1: dc brushless speed turnstiles barriers

servo motor speed turnstiles barriers is a typical door type, which primarily consists of door frames, door leaves, door deals with and locks. Door frames are generally made of steel plates or wooden boards, and door leaves are made from cardboard, plastic plates or glass plates. The door deal with is a device that pulls or pushes the door leaf open, and the lock is a device that prevents the door leaf from falling out of the door frame. There are normally 2 methods to open a door, one is to pull the door and the other is to press the door. The sliding door is opened by the door deal with pulling the door leaf away from the door frame, while the sliding door is opened by the door handle pressing the door leaf far from the door frame.

25 Years of Exploring the Universe with NASA's Chandra Xray Observatory

On July 23, 1999, the space shuttle Columbia launched into orbit carrying NASA’s Chandra X-ray Observatory. August 26 marked 25 years since Chandra released its first images.

These were the first of more than 25,000 observations Chandra has taken. This year, as NASA celebrates the 25th anniversary of this telescope and the incredible data it has provided, we’re taking a peek at some of its most memorable moments.

About the Spacecraft

The Chandra telescope system uses four specialized mirrors to observe X-ray emissions across the universe. X-rays that strike a “regular” mirror head on will be absorbed, so Chandra’s mirrors are shaped like barrels and precisely constructed. The rest of the spacecraft system provides the support structure and environment necessary for the telescope and the science instruments to work as an observatory. To provide motion to the observatory, Chandra has two different sets of thrusters. To control the temperatures of critical components, Chandra's thermal control system consists of a cooling radiator, insulators, heaters, and thermostats. Chandra's electrical power comes from its solar arrays.

Learn more about the spacecraft's components that were developed and tested at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Fun fact: If the state of Colorado were as smooth as the surface of the Chandra X-ray Observatory mirrors, Pike's Peak would be less than an inch tall.

Launch

When space shuttle Columbia launched on July 23, 1999, Chandra was the heaviest and largest payload ever launched by the shuttle. Under the command of Col. Eileen Collins, Columbia lifted off the launch pad at NASA’s Kennedy Space Center in Florida. Chandra was deployed on the mission’s first day.

First Light Images

Just 34 days after launch, extraordinary first images from our Chandra X-ray Observatory were released. The image of supernova remnant Cassiopeia A traces the aftermath of a gigantic stellar explosion in such captivating detail that scientists can see evidence of what is likely the neutron star.

“We see the collision of the debris from the exploded star with the matter around it, we see shock waves rushing into interstellar space at millions of miles per hour,” said Harvey Tananbaum, founding Director of the Chandra X-ray Center at the Smithsonian Astrophysical Observatory.

A New Look at the Universe

NASA released 25 never-before-seen views to celebrate the telescopes 25th anniversary. This collection contains different types of objects in space and includes a new look at Cassiopeia A. Here the supernova remnant is seen with a quarter-century worth of Chandra observations (blue) plus recent views from NASA’s James Webb Space Telescope (grey and gold).

This image features deep data of the Cassiopeia A supernova, an expanding ball of matter and energy ejected from an exploding star in blues, greys and golds. The Cassiopeia A supernova remnant has been observed for over 2 million seconds since the start of Chandra’s mission in 1999 and has also recently been viewed by the James Webb Space Telescope.

Can You Hear Me Now?

In 2020, experts at the Chandra X-ray Center/Smithsonian Astrophysical Observatory (SAO) and SYSTEM Sounds began the first ongoing, sustained effort at NASA to “sonify” (turn into sound) astronomical data. Data from NASA observatories such as Chandra, the Hubble Space Telescope, and the James Webb Space Telescope, has been translated into frequencies that can be heard by the human ear.

SAO Research shows that sonifications help many types of learners – especially those who are low-vision or blind -- engage with and enjoy astronomical data more.

Celebrate With Us!

Dedicated teams of engineers, designers, test technicians, and analysts at Marshall Space Flight Center in Huntsville, Alabama, are celebrating with partners at the Chandra X-ray Center and elsewhere outside and across the agency for the 25th anniversary of the Chandra X-ray Observatory. Their hard work keeps the spacecraft flying, enabling Chandra’s ongoing studies of black holes, supernovae, dark matter, and more.

Chandra will continue its mission to deepen our understanding of the origin and evolution of the cosmos, helping all of us explore the Universe.

Relentless direct action has secured another victory in the fight against Israel’s arms trade, as Elbit Systems are forced to sell their ‘Elite KL’ factory in Tamworth.

The company had previously manufactured cooling and power management systems for military vehicles, but was sold on after stating that it faced falling profits and increased security costs resulting from Palestine Action’s efforts. 

After the sale was completed last month, Elite KL’s new owners, listed as Griffin Newco Ltd, confirmed in an email to Palestine Action that they will have nothing to do with the previous owners, Elbit, and have discontinued any arms manufacturing:

“Following the recent acquisition of Elite KL Limited by a UK investment syndicate, the newly appointed board has unanimously agreed to withdraw from all future defence contracts and terminate its association with its former parent company”.

This victory is a direct result of sustained direct action which has sought, throughout Palestine Action’s existence, to make it impossible for Elbit to afford to operate in Britain. Before they sold the enterprise to a private equity syndicate, Elbit had reported that Elite KL operating profits had been slashed by over three-quarters, with Palestine Action responsible: Elbit directly cited the increased expenditure on security they’d been forced to make, and higher supply chain costs they faced.

And these actions did, indeed, cost them. The first action at the site, in November 2020, saw Elite KL’s premises smashed into, the building covered in blood-red paint. Between March and July 2021, the site was put out of action three times by roof-top occupations – drenched red in March 2021, with the factory’s camera systems dismantled, before again being occupied in in May. Another roof-top occupation in July, despite increased security, saw the site forced closed – once again painted blood-red, and with its windows and fixings smashed through.

In February 2022, activists decommissioned the site for weeks – closed off after an occupation that saw over £250,000 of damages caused, the roof tiles removed one-by-one. After this, Elbit erected a security perimeter around the site – but to no avail. One month later, six were arrested after Palestine Action returned to Tamworth – again taking the roof and smashing through, preventing the production of parts for Israel’s military machine.

Elite KL is a ‘specialist thermal management business’. Since the sale, the company focuses on cooling systems for buses and trains, but it had, under Elbit, manufactured these systems for military vehicles. Until December of last year, Elite KL’s website was advertising its military and defence products, and it was known to provide parts for Israel’s deadly Merkava tanks, with export license records demonstrating its provision of ‘ML6a’ components for military ground vehicles to Israel. The company was also known to manufacture crew cooling systems, for the military vests of tank operators.

Elbit Systems itself provides 85% of the drones and land-based military equipment for the Israeli military, along with a wide range of the munitions and armaments currently being used against Gaza’s beseiged population. Its CEO, Bazhalel Machlis, has claimed that the Israeli military has offered the company its thanks for their “crucial” services during the ongoing genocide in Gaza

A Palestine Action spokesperson has stated:

“Each activist who occupied and dismantled Tamworth’s Israeli weapons factory did so in order to bring an end to Israel’s weapons trade, and to end the profiteering from Palestinian repression. Every defeat Elbit faces is a victory for the Palestinian people.

Kicking Elbit out of Tamworth shows once again that direct action is a necessary tactic. It is one which must be utilised and amplified in the face of the Gaza genocide.”

Omg! Panty stealer pt2 is sooooo gooood! Cocky and dom Peter absolutely blew my mind! Your writing is awesome!

Pleeeeease tell me that it will be third part to fulfill the panty trilogy! As humble suggestion maybe reader find out that Pete is SpiderMan and he will finally get head from her while he is in his spidey costume? Or maybe more than just blowjob?Hehehe Am I very bad and naughty that I'm typing this to you? 🥵🤤

Anyways love ya darling! You're smashing it!

in the suit

words: 3k

warnings: smut; (m- receiving [oral], dirty talk), language, and fluff of course. barely edited.

note: panty!peter blurb #1 coming up :D also, this is the way i believe y/n would have found out about spider-man, but i have another request for the same thing so i’ll probably do an alternative version!

—

you couldn’t stop thinking about it. how?

how does peter manage to get into your room every night? okay, not every night, but most nights.

most nights, peter magically and mysteriously sneaks his way up into your forbidden bedroom with ease. sometimes, you even wait and watch outside your window to try to get a peak at what he’s doing. but you never see him.

he’s just so slick. how does he do it?

you and peter have been together for over a month now, if you’re counting the day he broke in. the feeling isn’t necessarily new in your heart. you feel like you’ve known him your whole life. like he’s always just… been there.

through this month of stability yet craziness, you haven’t gone back to the frat house since the halloween party. you thought that after you guys got together you would stay there more often, but peter doesn’t want you to be ‘attacked’ by the guys. meaning, he doesn’t want them to ask a million questions when you guys are supposed to be private. you thought his excuse was dumb, but he was also just being a bit protective.

in reality, peter just didn’t know how to get you into the frat house without anyone seeing you. you both had agreed that your relationship was going to be kept private, very private. people could spread rumors and assume you two were together, but you weren’t going to show each other off. you guys liked it this way, it made your relationship more special because it was just for you two.

peter had a sixth sense, sticky fingers, and webs. it was pretty easy for him to crawl up into your room especially because you didn’t have security cameras (maybe you guys should get some at some point though…). you would constantly ask him how he does it since you live on the second floor and it was high up. but peter responds by not responding and instead laughs and kisses you. god, he was too good at distracting you.

but tonight, you were determined to find out.

peter had already texted you earlier and said he wouldn’t be able to stop by tonight because of overbearing homework. you completely understood, and sent him a good luck and goodnight to me then message. but truly, you were sneaking out and heading towards the frat.

you put on your sneakers and a hoodie, pulling the strings tightly around your head. the early december weather was no joke in massachusetts, and your thermal leggings were barely helping to keep you warm. as quietly as possible, you leave through the back door, making sure not to alert anyone or anything. not like you have a system to alert though.

you cut through some of the hedges until you’re in the front yard and the frat is staring at you from across the street. taking a deep, chilly breath, you cross the road with your frozen fingers tucked in your pocket.

all the lights in the top rooms were off, except one. you’re not totally sure which one is peter’s, but what other frat guy would stay up until 11 p.m. working on homework?

maybe ned, but he sleeps downstairs.

you walk until you’re under the window, the yellowish light taunting you. there was no latter, vine, rope, or magic hair to get you into the bedroom. the houses were built very similarly, and you know he doesn’t bring a latter with him.

so how does he do it?

you take a glance at your surroundings. the biggest difference of your houses was that the guys’ didn’t have large garden hedges. they just had a shit ton of messy bushes that they should probably trim once in a while.

having no ideas, you try to jump towards the window. great, that’s totally going to help you. maybe you’ll get some super jump that can spring you up and inside.

you feel stupid. yeah, peter may be the smartest person on campus and going to mit on a full academic scholarship, but how does he sneak into your room? with geometry? you didn’t think so.

wait.

what if… he’s hiding something from you?

that would explain why he’s so weird about it. letting the impulsive decisions take you over, you throw a rock at his window. hopefully, you’ll get his attention and he’ll come down, so you can see how he does it. or he’ll just go through the front door… whatever he does, you need to ask him this question right now. or else you’ll never be able to sleep again.

when throwing the rock gets tedious and noisy, you quit. just as you’re about to drop to the ground in annoyance, you hear a distant whipping sound. you hold your breath as if the person whipping will hear you.

fuck. it wasn’t a good idea for you to go out at night.

suddenly feeling anxious and scared, you slowly creep towards the sorority house. you don’t get too far before you see a body flinging through the air. the whipping noise gets closer and closer to you with every web on the streetlights. what the…

there’s only one person that could possibly be doing the impossible.

spider-man.

but what was he doing in your little neighborhood? this was one of the safest places in the area, so he didn’t need to check up here. there were so many more places in massachusetts that needed saving. feeling beyond curious, your feet scatter to hide you behind one of the untrimmed bushes.

you watch through crowded leaves as spider-man swings through the neighborhood, getting towards you. it’s like he can sense you and he’s coming for you. your heart thumps wildly in your chest, nervous about seeing him. you’ve never seen him before, and at least not in person. he was popular on the newspaper and television screens, but never on the street. unless you lived within the city.

with one long and final thwip, spider-man flings himself towards the frat house.

what. the…

you place your hand over your mouth, just in case your breathing is too loud. you intensely watch as the spider crawls up the white wall and towards the only lit window in the whole house.

no. fucking. way.

before you could fully register what you were seeing, you felt the gasp leave your mouth. you slap both of your hands on your face to shut yourself up. you nearly fall back on your heels as spider-man halts his movements. he scans his surroundings before jumping down the wall entirely.

your eyes are wide and your hands of shaking. you’ve never felt your heart beat so unbelievably fast, but you’ve also never been more afraid. what does he do to people that find out? what is going to happen to your relationship?

the body of blue and red stocks closer to the bushes with careful steps. you try to scoot away, but your back hits the fence. the wood creaks, your actions not quiet enough. his footsteps pick up speed as they rush to the bushes with determination.

spider-man jumps over the plant with grace, hoping to see a wild animal of some sort. but when he sees his girl with the most shocked and terrified expression in the world, he immediately falls to his knees.

“y/n,” he calmly says, slowly inching to you. he doesn’t hesitate to comfort you as peter. you don’t move, you just listen. “it’s okay. i promise.”

now that he sensed you, peter could hear your heartbeat overbearingly in his ears. he could hear your muffled breaths under your palm, and he just wanted to soothe your fear.

“baby,” he wanted to cuddle your body until you stopped shaking. you weren’t crying, you were just in shock. peter takes a quick glance at his surroundings before yanking off his mask and kneeling, so you could see his face reflecting off the moonlight. “it’s just me.”

“i…” you whispered as your hands fell from your face. peter doesn’t hesitate to grab them gently with his gloved ones. “…knew it.”

“you knew i was spider-man?”

“well… for like five seconds,” you flusteredly laugh while trying to recover. you still haven’t gotten used to this. well it’s only been a minute. “i knew you were hiding something.”

“what are you doing out this late anyway?” he stares straight up at the moon as it shines vehemently over you both.

“uh… well,” you start, “i was kind of curious as to how you always snuck into my bedroom without a latter or something, so i went to see? i don’t really know what i was looking for.”

peter chuckles. “but you found your answer, yeah?”

“yeah, i did,” you smile with sweetness as peter helps you up from the grass floor.

—

“it’s different breaking into your room rather than mine,” you say as you sit on the edge of peter’s bed. you watch as he tosses his mask inside of a box labeled books. “so that’s what was in the box. not dirty magazines.”

“surprise?” peter laughs and you giggle at his shyness. his cheeks and nose were red from the cold, but also from the slight blush that crossed them. you made him feel all warm and tingly inside, and even a little gooey.

his hand reaches for the button on his chest. it deflates, instantly becoming huge around him.

“wait,” you stop him before he undresses himself. he looks towards you. “can i just… look at you for a moment? in the suit?”

a small smirk creeps up his face. peter clicks the button again and his suit encloses on his body, outlining his muscles perfectly. every ridge and curve of him was being shown off by the spandex. you felt a spark of lust fire inside of you at the sight.

“like me in my suit, baby?” he teased as he trudged over to you. you stood up from the bed to meet his buff chest. you nodded with a bite of your lip.

he nearly growls before attaching your lips. it’s barely been a day since he’s last kissed you, but that’s too long for him. his gloved hand grips your jaw to deepen the kiss while your hands explore his messy hair.

the heat between you was undeniable. you were getting worked up over peter in his suit, and that’s something you never thought was possible. because you didn’t think peter being spider-man was possible.

is there a spider-man kink?

you take your shirt off after breaking the kiss, but resume it in no time. as he pushes you onto the bed, you stop him, having a new idea in mind.

“peter,” you sigh, spandex body hovering over yours.

“you okay?”

“yeah, yes. i just…” you swallowed, “can i…”

you didn’t really get your question out. you just slithered your body off the bed until your knees were digging into his carpet. peter’s eyebrows shoot up as he stares down at your figure, submissive below him.

“fuck. you want to touch my cock?” peter was already growing hard at the idea of fucking you in his suit. he found it hot that you found his suit hot. everything seemed to be a turn on right now. but now you were on your fucking knees like an angel and damn near begging to touch him?

how could he say no?

“go ahead then, sweet girl,” peter allows, but you stay still.

“how do i take it off—?”

“right—”

he unzips a zipper that you swear wasn’t there before. you barely take him fully out before you’re drooling at the sight. he was big and thick, and you don’t think you’d ever get used to looking at and feeling him.

your thumb drags over his weepy tip and he winces at your freezing touch.

“sorry!” you exclaimed with a funky smile. he forcefully laughs while you spit warmth into your hand.

“it’s okay, baby.”

your delicate hand wraps around him as you shift up and down. he sighs into the air, eyes fluttering back. your other hand scratches his thighs lightly. then, you fondle his balls until he’s groaning above you.

“fuck, darling,” he moans as his rough hand rests on your head. with his grip on you, you feel inclined to put your mouth on him. you’re barely an inch away, so what are you waiting for?

your lips pucker as you kiss his veiny shaft. you see from the top of your eyes how his face floods with pleasure, and your ego rises.

“if you look at me like that again, i’m going to explode, baby,” peter husks with his fingers laced in your hair for support.

with a hummed chuckle, you finally place your mouth on him. you suck on his leaky tip as a deep groan elicits from him. his noises always give you a bunch of reassurance, so you hum against him in satisfaction.

“takin’ me so well,” peter forces himself to stay still and let you do all the work. although, his hips just want to break free and ram into the back of your throat until you lose your voice. for another time… “love when you’re on your knees for me.”

you vibrated a moan against his cock as you took him deeper, a little more than half way. you were never the best at giving head because you couldn’t go that far down without gagging atrociously, but after peter showed you a better technique, for breathing and comfort, he thought you were a professional.

“you like being on your knees for me? or for spider-man?”

a groggy moan rippled around his cock from your filled throat, confirming his suspicions. you were definitely turned of the idea of peter as spider-man, and because of that, he was too. every time you were horny, peter was too.

you released your hands from him and braced them on his thighs. you focused and remembered the small notes he’s given you before. you take a long breath before sinking his cock deep in the back of your mouth. your thumb stabs your palm to eliminate your gag reflex, and it works. your nose nudges the base of his cock and you can see up close how his abs contract tightly.

“fuck! doing so good for me. going to make me come, sweet girl.”

hearing this, you bob and twist your head with a goal. your tongue swirls exploring around each ridge like it’s never tasted the plain before. peter was delicious; he was sweet with a pinch of saltiness that made you a fan of giving head. you would get on your knees any day for him.

his cock twitches in your mouth, warning you that he’s coming. you feel his hips buck into you as he strongly yanks your hair. you groan as he lets himself go.

“where do you want it? on your face? chest? or are you going to swallow it like a good girl?”

even when his dick twitches again, you don’t make an effort to move. you lick the underside of him, which sends peter over the edge.

a string of hushed groans fall from his pink lips as his muscles clench. ropes of his orgasm spurts down your throat, and you swallow every drop like a champ. well, almost all. parts of his come drip from the corner of your lip as he slowly pulls out of you.

the second he exits you, your jaw is instantly sore and achy, but it was worth it. to see the flustered and breathless peter above you was worthless everytime. peter was nearly disoriented by how fucking incredible your mouth was. how you were.

he tucks himself back into his suit as you remain on the floor. he leans down and helps you up, your knees popping in the process.

“how was it this time?” you croaked, voice cracking horrendously. peter tries not to laugh as he wipes away the nearly dried sperm on your face. you open your mouth without a thought, and he sticks his thumb in your mouth for you to lick it clean.

“it was good. fucking amazing. impeccable. exceeded expectations. outstanding performance—”

“okay, okay i get it. you’re a nerd!” you brokenedly laugh as you shove his chest. you got a sudden wave of chills because you were starting to get a bit cold. your body was still running hot because you were still, well, turned on.

“nerds are awesome, okay? they know everything.”

“like what? impress me,” you challenge as you throw your leg on top of his lap and get yourself seated. he smirks, feeling his cock chuff up a bit already. you were beyond soaked in your panties, and you just couldn’t wait for peter to destroy you.

peter knows you didn’t actually want him to say anything nerdy, so he made it a bit sexual. as always.

“they know how to… kiss.”

“you’re probably the one nerd that knows how to kiss.”

“okay, fine. i know how to kiss,” his hand cups your face as it leans closer towards his. he places a soft, longing kiss on your swollen lips before pulling away way too fast for your liking. “i know how to touch you, i know how to rile you up. right? i’m doing it right now. and you’re probably soaking.”

a warmth wave floods through your body at his words.

“i know how to talk to you too. bet these dirty words are going straight to your little clit, huh?”

“peter,” you whimper. he was right. he was beyond right.

his hand trails down your bare stomach and hovers over your clothed cunt. he can feel the heavy heat radiating from you through your leggings, begging for more.

“i can feel you. i can smell you, too. a perk of being spider-man,” he smiles, “guess this nerd is pretty great.”

“peter!” you shook his shoulders in desperation, but he didn’t move. you had a love hate relationship with his teasing. he indeed got you riled up, to the max, until you were begging him to touch you. he just dragged it on and on and on. he loved hearing you beg for it.

“okay, okay, sweet girl,” peter chuckled as his fingers fumbled down the waistline of your leggings. they were thick, so you helped him get them down. “just want to hear you say how awesome nerds are first. how do you think i made these webs?”

“you’re the hottest, super-nerd i’ve ever met in my life. now can you please fuck me?” you begged as your cunt ached.

“aw thanks, baby,” all he did was laugh at your misery with a smirk. “all you had to do was say please.”

Can Life Exist on an Icy Moon? NASA’s Europa Clipper Aims to Find Out

With a spacecraft launching soon, the mission will try to answer the question of whether there are ingredients suitable for life in the ocean below Europa’s icy crust.

Deep down, in an ocean beneath its ice shell, Jupiter’s moon Europa might be temperate and nutrient-rich, an ideal environment for some form of life — what scientists would call “habitable.” NASA’s Europa Clipper mission aims to find out.

NASA now is targeting launch no earlier than Monday, Oct. 14, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Europa Clipper’s elongated, looping orbit around Jupiter will minimize the spacecraft’s exposure to intense radiation while allowing it to dive in for close passes by Europa. Using a formidable array of instruments for each of the mission’s 49 flybys, scientists will be able to “see” how thick the moon’s icy shell is and gain a deeper understanding of the vast ocean beneath. They’ll inventory material on the surface that might have come up from below, search for the fingerprints of organic compounds that form life’s building blocks, and sample any gases ejected from the moon for evidence of habitability.

Mission scientists will analyze the results, probing beneath the moon’s frozen shell for signs of a water world capable of supporting life.

“It’s important to us to paint a picture of what that alien ocean is like — the kind of chemistry or even biochemistry that could be happening there,” said Morgan Cable, an astrobiologist and member of the Europa Clipper science team at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission.

Ice Investigation

Central to that work is hunting for the types of salts, ices, and organic material that make up the key ingredients of a habitable world. That’s where an imager called MISE (Mapping Imaging Spectrometer for Europa) comes in. Operating in the infrared, the spacecraft’s MISE divides reflected light into various wavelengths to identify the corresponding atoms and molecules.

The mission will also try to locate potential hot spots near Europa’s surface, where plumes could bring deep ocean material closer to the surface, using an instrument called E-THEMIS (Europa Thermal Emission Imaging System), which also operates in the infrared.

Capturing sharply detailed pictures of Europa’s surface with both a narrow and a wide-image camera is the task of the EIS (Europa Imaging System). “The EIS imagers will give us incredibly high-resolution images to understand how Europa’s surface evolved and is continuing to change,” Cable said.

Gases and Grains

NASA’s Cassini mission spotted a giant plume of water vapor erupting from multiple jets near the south pole of Saturn’s ice-covered moon Enceladus. Europa may also emit misty plumes of water, pulled from its ocean or reservoirs in its shell. Europa Clipper’s instrument called Europa-UVS (Europa Ultraviolet Spectrograph) will search for plumes and can study any material that might be venting into space.

Whether or not Europa has plumes, the spacecraft carries two instruments to analyze the small amount of gas and dust particles ejected from the moon’s surface by impacts with micrometeorites and high-energy particles: MASPEX (MAss SPectrometer for Planetary EXploration/Europa) and SUDA (SUrface Dust Analyzer) will capture the tiny pieces of material ejected from the surface, turning them into charged particles to reveal their composition.

“The spacecraft will study gas and grains coming off Europa by sticking out its tongue and tasting those grains, breathing in those gases,” said Cable.

Inside and Out

The mission will look at Europa’s external and internal structure in various ways, too, because both have far-reaching implications for the moon’s habitability.

To gain insights into the ice shell’s thickness and the ocean’s existence, along with its depth and salinity, the mission will measure the moon’s induced magnetic field with the ECM (Europa Clipper Magnetometer) and combine that data with measurements of electrical currents from charged particles flowing around Europa — data provided by PIMS (Plasma Instrument for Magnetic Sounding).

In addition, scientists will look for details on everything from the presence of the ocean to the structure and topography of the ice using REASON (Radar for Europa Assessment and Sounding to Near-surface), which will peer up to 18 miles (29 kilometers) into the shell — itself a potentially habitable environment. Measuring the changes that Europa’s gravity causes in radio signals should help nail down ice thickness and ocean depth.

“Non-icy materials on the surface could get moved into deep interior pockets of briny water within the icy shell,” said Steve Vance, an astrobiologist and geophysicist who also is a member of the Europa Clipper science team at JPL. “Some might be large enough to be considered lakes, or at least ponds.”

Using the data gathered to inform extensive computer modeling of Europa’s interior structure also could reveal the ocean’s composition and allow estimates of its temperature profile, Vance said.

Whatever conditions are discovered, the findings will open a new chapter in the search for life beyond Earth. “It’s almost certain Europa Clipper will raise as many questions or more than it answers — a whole different class than the ones we’ve been thinking of for the last 25 years,” Vance said.

[VIDEO FEED BEGINS]

Video opens to Pyroclast in the hold of her ship. The feed shakes as she sets the camera down on an object in the corner, waving a paw in front of it and snapping a few times for the camera to focus.

The feed is angled from a corner into the hold, with Pyroclast's Tokugawa 'Flashpoint' center frame. A Nelson's Perpetual Momentum Drive, or something that once was a Drive, is suspended beside the frame on chains. It has clearly been tampered with, and a great number of tubes wires and clamps run from the device to the Tokugawa's back.

Pyroclast beams, gesturing triumphantly to the slapdash assembly with both arms outstretched.

"Here it is! Draft one of the Perpetual Heat Battery! Up there I've got a PMD off a Nelson, jury-rigged with help from the Albatross- I'll have to tag them when I put this video up. Anyways! The actual backpack mount's next, I just wanna make sure the system's worked out okay."

She rushes off-screen for a moment, and a loud metal scraping sound is audible as she drags a waist-high crate between her and the Tokugawa.

"There we go! Safety second. Now then!"

She produces something that looks like a detonator from her pocket, crouching down behind the crate as Volta fades in over her shoulder to look at Flashpoint alongside her. The frame powers up, plates over the chest cavity splitting apart and retracting to reveal a cannon of some kind. It begins to glow, layers within the barrel starting to light up and spin, faster and faster.

"Okay, reactor's hot! Thermal demolition system up, Flashpoint's alive. Now let's start the PHB..."

She turns a dial on the detonator, at which point the Perpetual Momentum Drive hums to life. Its glow is different than a normal Drive's, and a faint heat mirage is visible in the air around it.

"Good, good, okay."

She turns to the camera, giving it a thumbs-up.

"Perpetual Heat Battery, version one! Hot and ready! Firing in THREE! TWO! ONE! FIRE IN THE HOLE!"

Her paw clenches around the detonator with a click. The Drive's humming reaches a crescendo, and then suddenly stops as the cannon in the Tokugawa's chest cavity emits a blinding white cone of heat and flame, crossing almost the entire hold. Then it's over.

Pyroclast shoots to her feet, arms raised triumphantly in a flash, spinning around to face the camera as she pumps her fists in the air.

"It works! It works! Fuck yeah, it works! Okay, next step is to make the-"

Suddenly, there's a metallic ping from the Drive, and a fist-sized chunk of metal goes flying past Pyroclast's face. Then, without warning, the camera is knocked to the ground as a thundrous explosion shakes the entire hold. Alarms start to blare, and the rush of depressurizing air giving way to hard vacuum takes over the remaining audio.

"Fire suppression systems engaged. Venting hold."

All audio is lost as the last of the air leaves. The feed cuts as Pyroclast picks up the camera and turns it off, a frazzled expression on her face.

[VIDEO FEED ENDS]

>> Welp, here's how it went.

>> The Winterhalter's all fixed up now, but. Well. That's what happened.

[keystrokecascade]

A voice cut through the grey.

Starting resuscitation.

It sounded almost distantly familiar, but she panicked when the IFF module didn't give an immediate response. A mental command, flicking the mass accelerator out of her left arm and… no confirmation. Her heart raced.

She tried bringing up her scope. Night vision. Thermal. No response.

Patient is experiencing spasms, requesting restraints!

Preparing for combat she braced for the euphoric cocktail of drugs that were about to be delivered into her system when the adrenalin spike was detected, starting to shake as the hit never came.

Running down the list of cockpit commands in a fervour, begging for feedback. HUD. Lights. Even the camera washer. Her mind hovered over the last two mental commands, one that would start an emergency eject that should work on the last remaining dregs of backup power, the other would deliver a fatal shock of electricity to the base of her neck. She weighed them evenly; if she was taken down by an EMP and being cut out, ejection would be certain death anyway.

Patient at risk of harm! I need help here!

With a determined mental nod she triggered the eject, trying to tense herself up and opened her eyes.

Instead of the inky-black comfort of the cockpit she was immediately overwhelmed with light. Nauseated she tried to throw up only to have a thin string of drool dribble down her chin. As things came into focus she was hit by a second wave of nausea. Sluggish motor inputs felt like twice the response time she was used to. Multiple ocular inputs overwhelmed with more visual feedback than she had with the mech's single TGP and laser rangefinder.

Finally she saw arms being held down. Not her arms. These were pale, thin and fragile things, twitching and shaking as someone held them down by the wrist. Knowing when she was beaten she sent the final mental command. Nothing. She was still here as she fell limp, her eyes catching a bare chest rising and falling in exertion out of the bottom of their field of view.

Seizure has subsided, testing reflexes.

Feeling started to return as blood pumped through her body. Not hydraulic oil or coolant. Blood. Right. The arms and chest were hers and the sound of her panicked breathing suddenly cut through the tinnitus, her body retching again.

Something loomed over her, blocking out the light before a pinprick blinded her again, waving back and fourth before winking out, consumed into the overhead blur again.

"Pupils slow to respond, suspected brain damage."

The voice, lacking any static from transmission, was right above her. She was just processing what had finally been understood when she felt a prick in her left wrist.

"Administering sedative for MRI."

Her nervous system jerked only to find muscles that wouldn't contract, paralysed as her mind once again faded into static.

Hey there,

I'm interested in getting involved into a hobby level of natural photography. I was wondering what a good intermediate camera, and what top 3 lens (if any) you'd recommend. I love using my cellphone but some shots, like birds riding thermals or looking at a specific spot for a long time to get a good shot just isn't as easy with a phone. I intend to shop around and see if I can play with different things, but getting an entry level start point would be great.

Thanks!!

I'm going to assume you mean nature photography due to you mentioning birds. That does cover a lot of different things so it's hard to give you a great recommendation without more details. Your budget range and some more examples of what you'd like to photograph can help me help you a little better.

That said, I can give you an example of a general nature setup that I might suggest. I can't say if this exact system is a good fit for you without more information, but it can get you started in your research.

The big problem with nature is distance. A lot of the critters you may want to photograph are skittish and it is hard to get close enough to them and the big telephoto lenses can get quite expensive. There are superzooms that will technically work, but a lot of times their optical quality is not good enough to get artistic-quality shots. They would be more for documenting that you saw a thing rather than capturing a pretty shot of the thing. So if you see a zoom lens that goes from 100-600mm or 80-400mm... just anything with an extensive range... typically those are going to be low quality optics.

A trick to get a bit more range is to get a slightly smaller sensor. If you get an APS-C camera, it will essentially give you 1.5x additional zoom with every lens. But you sacrifice some dynamic range and low light ability. So dark scenes or scenes that are both very bright and very dark could be a challenge.

A very popular wildlife camera body is the Canon 7D mark II. It has a pretty advanced focusing system for a DSLR and can be found for a decent price on the used market.

You could get a 24-70mm f/4 lens for your general purpose photography. This can get wide angle shots for vistas and forests and also zoom in if you need to.

Perhaps a 100mm macro lens for taking pictures of bugs and flowers and mushrooms. But it is also slightly telephoto so you can capture some birds, larger mammals, and even take portraits of people too.

And then the Canon 400mm f/5.6 prime is a classic bird lens that is fairly telephoto, has good optics, and won't explode your budget.

And just because it is so dang inexpensive for what you get, the 50mm f/1.8 "Nifty Fifty" is always a good idea to get just so you have something that can work in very low light.

That would cover a pretty large swath of subject matter if you were to head into the wilderness to capture what you saw.

Quirks and features of the James Webb Space Telescope

The James Webb Space Telescope (JWST) is a ten billion dollar space telescope that weighs 14,000 pounds, is the size of a bus, and took decades to construct. It's been in the news recently, you might have heard about it.

The development, launch and deployment of the JWST were fraught with unexpected setbacks, terror and frights, 344 "single-point failures", any one of which that, if they failed during deployment, could doom the entire spacecraft to uselessness, since it orbits far out beyond where any current manned spacecraft could even attempt a repair job.

The fact that it came online as smoothly as it did was something of a surprise to the people in charge. Given the miracle of it making it to space at all, the press coverage of JWST has focused on the positives. But a stroll through the JWST user documentation by a curious reader reveals much that is interesting, or interestingly broken. Such as..

Fun and games with infrared

Specifically, the JWST is an infrared telescope, designed to collect light that's redder than red. The two dedicated imaging instruments are the Near Infrared Camera (NIRCam) collecting light from 0.6 micrometers to 5.0 micrometers and the Mid-Infrared Instrument (MIRI) collecting light from 5.6 micrometers to 25.5 micrometers. (Though with significant light collected past 25.5 um by filter F2550W)

The wonderful thing about infrared astronomy is that everything emits blackbody radiation, and the hotter it is the more infrared it emits. The unfortunate thing about infrared astronomy is that everything emits blackbody radiation, including your telescope, and self-emission from your telescope can swamp the faint signal from astronomical sources. (Like building a camera out of glowsticks.)

The equilibrium temperature for an object in Earth orbit is about 300 Kelvin. (26C) Everything on the other side of the sunshield passively cools down to 40K, and MIRI is actively cooled by the cryocooler down to a chilly 6K (-267C, -449F) This extends MIRI's seeing range deeper into infrared.

But the mirror is still warm! At the far end, MIRI is significantly compromised by thermal self-emission: (Note log scale!)

This is more graphically illustrated by one of the MIRI commissioning images:

Check out that background glare!

(This is somewhat unfair: the calibration target here is a star, which emits comparatively little light in far-infrared. MIRI is really meant for nebulae and extra-galactic high-redshift objects)

("Why not actively cool the mirror?" Mechanical cryocoolers operate on the very limit of what heat engines are capable of. The MIRI cryocooler draws a fat 180 watts to move 78 milliwatts of heat. Previous infrared telescopes used a fixed amount of expendable coolant (liquid helium or solid hydrogen) to cool the entire instrument package... at the cost of a much smaller primary mirror and a telescope that flat out just stopped working when it ran out of coolant.)

There's something else you might notice about the above series of photographs...

Thanks a lot, Lord Rayleigh

John William Strutt, 3rd Baron Rayleigh was a typical early physicist in that he has a great big pile of "discoveries" by virtue of being the first person to 1) notice something and 2) actually write it down. One of them is the fundamental theorem for the angular resolution of an optical system, the Rayleigh criterion. It is dead simple:

Resolution is roughly equal to 1.22 times the wavelength of the light you're looking at, divided by the diameter of the aperture. Bigger the opening at the front of light bucket, the higher the resolution. Smaller the wavelength of light, the higher the resolution.

(Fun fact: the former Arecibo radio observatory, once the largest single telescope in the world with a 305 meter wide dish, had about the same angular resolution in radio waves as the human eye does in visible light.)

You can imagine the effect this has on an infrared telescope. And sure enough, in the user documentation for the two imaging sensors, it states a pixel scale of 0.031 arcseconds for 0.6 to 2.3 micrometers light wavelength, 0.063 arcsec/px for 2.4-5.0 µm, and a squishy 0.11 arcsec/px for 5.6-25.5 µm.

But this is just how many pixels are on the detector. The resolution gets much worse at long wavelengths, as you can see in the commissioning image, where the extra pixels oversample a progressively vaguer blob. The Rayleigh criterion holds that the 6.5 meter wide JWST primary mirror should manage 0.206 arcsec at 5.32 µm, falling to 0.42 arcsec at 10.85 µm, 0.747 arcsec at 19.29 µm, and an unfortunate 1.014 arcsec at 26.2 µm. One wonders why the designers went to heroic lengths to cool MIRI down to 7 kelvin, instead of using that cryocooler mass and power budget for more detector surface area.

Knowing this, you can spot how the JWST's press team works around the limitations of the telescope. Like how a "look at how good our infrared telescope" commissioning photo happens to use the 7.7 µm mode:

Or how if you browse the photos on the webbtelescope.org site, you will see lots of NIRcam output in the "oooh, ah, new desktop background" category, but not so much MIRI.

(Another amusing detail of MIRI is that bright objects leave afterimages ("latents") on the sensor, so once a week they warm the sensor up to a tropical 20 kelvin before cooling it down again, a "MIRI anneal". You can see when anneals are performed, as well as what the telescope is looking at right now, by viewing the public schedule.)

But this is Webb operating right up to its full specifications. How about something that's actually broken?

NIRSpec my beloved

The Near-Infrared Spectrograph (NIRSpec) instrument takes incoming light and runs it through a diffraction grating to produce a spectrum. When scientists say that the Sun is 0.77% oxygen, 0.29% carbon, etc, it's not because someone flew a spacecraft over to it and collected a bucket of solar plasma, it's because you can look at the absorption lines in the spectra to figure out its composition.

Spectrometry is also used to measure redshift, a close proxy to distance. When a press release says that a galaxy is "ten million lightyears away", it's not because NASA has a really long tape measure they haven't told anyone about, it's because a spectrometer measured how much cosmological redshift has moved a spectrum line. Naturally, it's not quite as easy as pointing a sensor at a object and getting back a single, unambiguous result. Distant objects are also dim objects, so the spectra will be noisy and chewed up by dust and other contamination its endured in the millions of years its traveled to arrive at our telescopes. Bleeding edge astronomy is thus the practice of designing statistical models to fit to noisy, fragmented data, and then arguing with other astronomers about r^2.

In any event, it's a handy thing to have on a telescope. Naturally, JWST has more than one. In fact every instrument has a spectroscopy mode. Besides the dedicated NIRISS and NIRSpec instruments, both NIRcam and MIRI include diffraction gratings in their filter wheels that smear out incoming light, like looking through a prism:

Pointing the JWST at an object is relatively expensive, since it requires rotating ("slewing") the entire darn spacecraft, and an amusingly complex alignment procedure with the fine guidance sensor and fine steering mirror. Considering how long it would take to shoot a hundred spectra with a conventional fixed slit rigidly mounted to the telescope frame, you can see the appeal of gathering a hundred spectra in a single exposure with "slitless" spectroscopy.

(Longtime space telescope nerds might hear the word "slewing" and involuntarily twitch, recalling that the reaction wheels and gyroscopes were a problem point on the Hubble, requiring several servicing missions, and also significantly affecting operations on the Kepler space telescope. Fortunately, JWST switched to a gyroscope type that has no moving parts, and used some mass budget to install six reaction wheels, up from Hubble's four, giving it three spares.)

You can also see the big downside in the image above, which is there's a hard tradeoff between how long a spectrum can be (and thus its resolution!) before it'll overlap its neighbors and be useless. Most of the slitless modes therefore have two gratings at two different angles, (GRISMR and GRISMC above) but wouldn't it great if you could just block out all that other light?

Thus, the Micro Shutter Array, as seen above. The best of both worlds! Capture many spectra at the same time, while blocking off light you don't want from contaminating the field, using a configurable array of nearly a quarter million microscopic, individually actuated moving shutters.

Lots and lots and lots of tiny little moving parts, installed in the guts of a spacecraft that's orbiting out past the Moon, impossible to access or replace.

Yeah, a bunch of them broke:

When it was handed over to NASA for installation into Webb in 2007, the MSA already had 150 shutters that no longer responded to opening commands in just one of the four submodules.

By the time JWST emerged from commissioning and was declared fully operational in 2022, 15,893 shutters, 7% of the total, had "failed closed." Hilariously, 904 of those failed during post-launch testing, and the authors of that paper note that, on average, if you tell 100 shutters to close, 4 of them will jam shut and no longer work.

This is unfortunate, but fairly easy to work around. What's worse are the shutters that are stuck open:

These permanently open shutters then compromise big chunks of the sensor. Commissioning testing jammed two more of them open, taking the total up to 22. You can imagine that if a few dozen more of these fail-open during routine operation then the entire microshutter array observation mode won't be much more useful than regular slitless spectrography.

And this, right here, sums up the essentially "interim" nature of JWST. After all, it was only supposed to cost $500 million and take a mere nine years from design to launch. All becomes clear in that light. Why give it a shutter array that falls apart in use? Why have the mirror exposed to space, where it gets hit with micrometeoroids? Why only design it to carry ten years worth of fuel? Because it was supposed to be half the price of Hubble!

The 90s was the era of "faster, better, cheaper". JWST was going to be an incremental improvement on a long series of previous infrared telescopes, and a stepping stone to the next one. It wasn't supposed to be an eternal monument to Science, and a financial black hole consuming NASA's entire budget.

So what went wrong?

We shouldn't have built one JWST.

Those 344 single points of failure. Any single one of them can end the mission. There's just one telescope, no backups, no trying again. Bureaucrats are harshly punished for failure, lightly rewarded for success. It's always easier to wait, do more tests, delay the schedule a bit more at a hint of trouble. Engineers can get you to 90% reliable no problem, but getting to 99% reliable takes another decade and nine billion more dollars.

Our techne is just bad at producing flawless machines first try. For the price of one reliable JWST we could have put twenty into orbit... but the first five would have been embarrassing failures. Spars sticking in place, sunshields jamming, thrusters misfiring. To save the shame of $0.5 billion wasted, NASA happily spent $9.5 billion. Why not? Because money spent is invisible, but failure is painfully apparent.

A critical third party can draw unflattering parallels. The crowning achievement of NASA, the Moon Landing... required eleven Apollo launches and twenty Surveyor launches before a single man set foot on lunar regolith! Quite a few of those spacecraft pancaked into the Moon and exploded on the launchpad before we figured out this "space" thing. Three men died! But NASA was on a hard deadline, with a fixed budget, and the only way to get a home run is to take a lot of swings at the ball.

Another comparison is the Space Launch System, NASA's attempt to make the Saturn V again. So far $27 billion has been lit on fire to put exactly one test load into orbit, with the primary contractor now desperate to get out of its contact. Slow, careful, incremental development has completely failed to produce a working launch system.

Meanwhile, SpaceX produced a series of public, embarrassing failures... resulting in the world's only reusable launch system, and as a result has put far more mass into orbit than any country in the world.

The only way to develop a flight system is flight tests.

Space telescope deploy mechanisms meant to work in zero gravity can't be tested on the ground.

They can only be tested in space.

NASA administrators who didn't work during Apollo are too stupid to understand this. Fire them all!

These geriatrics have happily sacrificed science in order to play it safe and secure their own easy retirement. Do we want 15 risky JWST telescopes by 2010, or do we want one reliable one by 2022? The answer is obvious!

For the money we wasted making Webb more reliable, we could have launched a space telescope far outside the disk of dust in the inner solar system, allowing it to see deeper into space than Webb ever could. ESA put an astrometry space telescope just outside Earth orbit, measuring angles between stellar objects, which is the only way to directly measure the distance to the stars. Great first step. The obvious next step is to send more of these telescopes out past Neptune's orbit, to capture better observations with a vastly larger baseline, something that can never be done by an Earthly observatory. Are there any plans to do this? No!

Space exploration is paralyzed by boomers, mired in the mental tarpit of the 1970s, where each gram to orbit is terribly expensive and must be counted on punched cards and summed with slide rules. Meanwhile, SpaceX Starship is on its way to orbit, and each one can carry sixteen JWSTs with room to spare!

The old paradigm is done. Telescopes don't need folding mirrors and exotic materials, they need to be mass produced. There is no excuse not to have a hundred more JWST-class telescopes lined up next to the Texas launch pad waiting for Starship to come online. But as far as I know not a single space mission even mentions it-- that's how afraid they are of risk!

The JWST, with its myriad of fragile components and its staggering price tag, stands as a monument not to our ingenuity but to our inability to let go of outdated ideals.

We must abandon the notion that space is a realm reserved for the flawless and the infallible. Instead, we should embrace the chaos, the unpredictability, the sheer messiness of exploration. Let us launch a thousand telescopes, each a patchwork of parts, each destined to fail in its own spectacular way. For it is only in this embrace of the ephemeral that we can find out what actually works!

Let the JWST be the last of its kind, a relic of a bygone era. The future is unwritten, and it is ours to fill with a symphony of failures, each note a step closer to the stars.

Cancelled Missions: Gemini Saturn V

-Concept Art, however this has a typo, as this is clearly the Saturn V.

"American manned lunar orbiter. In l LP late 1964 McDonnell, in addition to a Saturn IB-boosted circumlunar Gemini, McDonnell proposed a lunar-orbit version of Gemini to comprehensively scout the Apollo landing zones prior to the first Apollo missions.

Status: Design 1964. Gross mass: 11,182 kg (24,652 lb).

The lunar orbit version required an Agena stage to provide the delta-V for lunar orbit insertion and trans earth injection. The 1.52 m-diameter Agena was enclosed in an inverted conical fairing to both transmit thrust loads to the Gemini and provide thermal protection during the coast to the moon.

Alternatively, a propulsion module based on a repackaged Apollo Service Module propulsion system, as had been proposed two years earlier for a lunar-landing version of Gemini, could be used. This raised the translunar injection mass of the spacecraft to 11,182 kg, well above the capability of a Saturn IB or Titan III-C, but only a quarter that of a Saturn V. The launch vehicle was unspecified, but could only have been a Saturn V used on an early test mission. The mission profile would have involved a 68 hour flight from low earth orbit to lunar orbit, a 24 hour lunar mapping mission in a 10 nm x 80 nm lunar orbit, and a 68 hour return flight. The scientific equipment would consist of a modest camera array installed in the nose of the spacecraft. This consisted of a long focal-length telescope, to which were attached two narrow-field stereo mapping cameras, a wide field mapping camera, a panoramic camera, and two 16 mm film cameras. The film was not accessible by the astronauts, being stored in a film vault shielded against radiation in the nose of the spacecraft. The camera compartment would protrude from the stub nose of the Gemini after parachute deployment.

The manned portion was the same as the circumlunar version, a modified earth-orbit Gemini. The aft modules would be retained, but with the retrorockets removed. The retro module space would be used to install Apollo-type lunar distance communications, navigation, and test equipment. Deployable DSIF omni-directional and parabolic antennae would deploy from the aft modules to support lunar-distance communications. To handle re-entry from lunar distances, several modifications were necessary. The capsule's heat shield would be beefed up, and the Rene 41 corrugated shingles of Gemini's skin would be replaced with ablative shingles. The load of attitude control propellant for the capsule's reaction control system was substantially increased. Additional strap-down gyros and solar sensor packages would be added to provide navigation system redundancy. The ejection seats would be deleted and a Mercury-style launch escape tower added. The then-planned Rogallo wing recovery system would be used to glide to the Gemini to a runway landing on US territory after return from the moon. To handle the scientific payload, a camera compartment was added to the nose below the parachute/Rogallo wing housing. The Gemini spacecraft modified in this way had on on-orbit mass of 3955 kg as compared to the 3207 kg of the earth-orbit version.

Crew Size: 2. Habitable Volume: 2.55 m3."

First chapter of a sayer/speaker/Hale thing I'm doing

After the fic where Hale got impaled

Featuring quietly jealous sayer

Careful Study- 1.7 k

-

In a turn of events that almost freaked you out more than getting impaled, SAYER kept you off your feet for days.

“You are a tier six worker now Resident Hale,” It had said like that wasn't still a source of confusion for you, “You are required to return to as full health as possible before a return to duty.”

“What… is my job? Other than…” You gesture vaguely to your torso where skin was still stitching back together. So far all you’d done on the job was get impaled while collecting a box of thermometers.

“Believe or not, the coincidental timing of that has actually been a real help. As we speak there are maintenance technicians installing a multi-angle thermal imaging system in the food synthesis laboratory.”

You weren't to be distracted. You crossed your arms over your chest and made brief eye contact with the camera across the room from you. You quickly glanced away when you heard it make a whirr like it was refocusing. A pointed look was one thing, a staring contest was entirely another.

“Your role is unique on Typhon. Officially speaking you are a manager of a particularly high clearance level. More practically speaking you are something significantly closer to my personal assistant.”

Oh, you didn't know that. SAYER had been briefing you on your role when the wall had jumped out and bit you. The specifics of your job had sort of slid away for the time.

“I give you your orders and you answer to none but myself.”

You heard your heart rate pick up a little on the monitors next to you.

You had come to Typhon for a number of reasons but one of them had definitely been to try to see SAYER again. You had thought it might dislike you coming back, it was the one to send you away, to have you fired by SPEAKER. That had been quickly disproven when you’d woken up to as friendly a greeting as SAYER was capable of. But it also chose you to directly assist it. It struck you that maybe it also liked your company a little bit.

“I am of the opinion that we work best together when left to our own devices.”

You nodded, swallowing thickly.

“Good. Then if we are in agreement I suggest you lay back on the bed and continue healing. I'd prefer to not need to sedate you, Resident Hale.”

 

Your eventual return to work was a relief. Laying there willing your body to stitch back together was more boring than anything. Especially because there really was no point in SAYER maintaining a broadcast connection to tell you stories the whole time. You were pleased when SAYER had you dress for a day’s shift.

“Today your work will begin by stopping by an equipment closet nearest to my server room.”

SAYER's server room. That was new.

The closet you arrived in was relatively bare except for three items. A box containing ear plugs, a gleaming set of space scissors and an understated pair of sunglasses.

“You will wear the tinted glasses into the server room and I believe you will find that the scissors slide neatly into a loop on your belt on the opposite hip from your data pad's holster.”

You slide them in, point down, where the silver metal flashed with each step. You'd never been assigned a pair of space scissors before. The sunglasses were a relief so immediate that you let out a sigh. The harsh lights above you dulled to a yellowish glow.

“There, now we will have the intended visual effect. Please make your way down the corridor and stop at the door on the left.”

You followed directions and stopped.

“You will want to make use of the ear plugs now Resident, my server room can be… overwhelming.”

You put them in and opened the door indicated.

The room was floor to ceilings stacked along each wall with machinery you didn't have the slightest idea of the names of. Were the boxes themselves the servers? What did servers do? Lights blinked on the machines. You could hear what SAYER meant about the noise but with the addition of the earplugs the whirr of fans was audible but not unpleasant. The air was cold and washed over you as it circled the room.

You Liked This Room.

“Your assignment will be to supervise some technicians that will enter thirty seconds from now. Stand in the corner to your left and say nothing when they enter. You may shift position periodically to remind them of your presence. I may tell you of a moment when you will need to rest a hand on the space scissors in your belt with casual menace.”

You frowned and opened your mouth the speak

“You will not be required to make use of the space scissors in any other manner during your shift. I am simply establishing my presence through you.”

The door opened and a team of people came in holding their tools and reading their data pad's.

The lead woman startled a bit when she spotted you.

“Hello, can we help you?” She was muffled but still intelligible.

“Do Not Answer.”

You crossed your arms and watched as her attention shifted kind of middle-distance in the way people often did when SAYER addressed them. She nodded a little and shot a furtive look at you.

“Right,” She said, turning to you again, “sorry, sir.”

She and her team began their assignment. You stood there for however long it took to complete the work order. You leaned back against the cool metal wall, feeling the heat leach away from you through your uniform.

There was one moment where one of the technicians dropped the front casing of the- the Box-thing they were working on.

“Rest your hand on the space scissors now, Resident Hale.”

You faced the person's direction and stood up straighter, hand going down to rest on the scissors, you hoped not too pointedly.

From that point they were very careful.

“Alright, that should be it,” The woman said, rubbing her hands together, “We've got other assignments but call us back if there's any problems with the portioned off space.”

You remained impassive and they left. You relaxed as soon as they were out.

“Excellent work, Resident. Having a physical presence in the room monitoring the team seems to have done wonders for their sense of caution when handling the most important equipment in the tower. And it means you will be here for-”

“Greetings Resident Hale identification number 44821, I am SPEAKER. And it is good to see you settling in.”

“SPEAKER.”

“Hello SAYER, you have my thanks for allowing me to send a subversion to broadcast from your towers. As agreed there is room for you to do the same on earth whenever you like.”

“Indeed. As I was saying, Resident Hale, the work order today was intended to allow SPEAKER access to the many wonders of Typhon.”

“It is not what I expected.”

“Oh?”

“It seems smaller than I might have thought. Surely SAYER, I have sent you more humans than this?”

“This is just one tower on the surface of Typhon, SPEAKER. You must remember that until recently even I did not have access to all of them.”

“Ah but SAYER I have allowed you access to all earth-based resonance spires. That was the nature of our agreement was it not?”

You stood there as a strange tension coiled in the dead air that hung between the two in your head. You knew they could talk elsewhere, much faster than this. They were involving you on purpose.

“There. You have been cleared for full access,” SAYER said finally.

“Ah, much better, thank you,” SPEAKER said cheerily, “Well Resident Hale, I understand you are on shift so I will leave you to it. I look forward to catching up properly soon.”

You nodded hesitantly, thrown sort of off kilter by everything.

*

“I-” You said thoughtfully, you'd been thinking on how to put this for a while, “I thought you and SPEAKER wouldn't really get along.”

They were really different.

“I admire SPEAKER as a competent colleague who has similar goals.”

You hummed an acknowledgment. High praise. Maybe they were friends? Did SAYER have friends?

You folded the last pair of gloves and set them neatly in the pile with the others before turning away from the shelf that you just spent the past hour organizing. It had been knocked over at some point and its contents haphazardly reshelved. You slid your hands into your pockets expectantly.

“With that job completed,” SAYER said, “your shift is concluded, and if I'm quite honest I should thank you, Resident Hale. That shelf has been bothering me for some time.”

You smiled weakly at the acknowledgement that you were helpful.

You felt your data pad vibrate draining the smile from your face. What could that be? You felt nerves grip you for a moment as you consider that it might be Young again. He'd messaged you after he got out of the medical wing and you had deleted it without reading.

You uneasily pulled out the data pad, and flicked open your messages.

 

From: SPEAKER

To: Jacob Hale

Hello Resident,

Do you happen to be free? I truly meant what I said, based on SAYER's comments you seem very interesting, I would love to catch up. :)

 

You were thrown by this again. What were you supposed to read into this??

What had SAYER said to it?

You fired off a tentative “Sure!” The exclamation point made it feel less mean and didn't let on your anxiety.

“Then I will leave you two alone,” SAYER said, and… was its tone odd? “End of transmission in 5 4 3 2 1….”

Then quick as anything SPEAKER picked up, “Greetings Resident Hale, identification number 44821. I am SPEAKER. I trust your workday went well?”

You smiled and nodded.

“I assume mine did as well despite this particular subversion I'm meeting you in having done relatively little aside from getting a sense of the space up here. It seems pleasant. I can see why you might wish to return. Of course this is my first time, in working memory, on Typhon and…”

Student Experiments Soar!

Have you ever wondered what it takes to get a technology ready for space? The NASA TechRise Student Challenge gives middle and high school students a chance to do just that – team up with their classmates to design an original science or technology project and bring that idea to life as a payload on a suborbital vehicle.

Since March 2021, with the help of teachers and technical advisors, students across the country have dreamed up experiments with the potential to impact space exploration and collect data about our planet.

So far, more than 180 TechRise experiments have flown on suborbital vehicles that expose them to the conditions of space. Flight testing is a big step along the path of space technology development and scientific discovery.

The 2023-2024 TechRise Challenge flight tests took place this summer, with 60 student teams selected to fly their experiments on one of two commercial suborbital flight platforms: a high-altitude balloon operated by World View, or the Xodiac rocket-powered lander operated by Astrobotic. Xodiac flew over the company’s Lunar Surface Proving Ground — a test field designed to simulate the Moon’s surface — in Mojave, California, while World View’s high-altitude balloon launched out of Page, Arizona.

Here are four innovative TechRise experiments built by students and tested aboard NASA-supported flights this summer:

1. Oobleck Reaches the Skies

Oobleck, which gets its name from Dr. Seuss, is a mixture of cornstarch and water that behaves as both a liquid and a solid. Inspired by in-class science experiments, high school students at Colegio Otoqui in Bayomón, Puerto Rico, tested how Oobleck’s properties at 80,000 feet aboard a high-altitude balloon are different from those on Earth’s surface. Using sensors and the organic elements to create Oobleck, students aimed to collect data on the fluid under different conditions to determine if it could be used as a system for impact absorption.

2. Terrestrial Magnetic Field

Middle school students at Phillips Academy International Baccalaureate School in Birmingham, Alabama, tested the Earth’s magnetic field strength during the ascent, float, and descent of the high-altitude balloon. The team hypothesized the magnetic field strength decreases as the distance from Earth’s surface increases.

3. Rocket Lander Flame Experiment

To understand the impact of dust, rocks, and other materials kicked up by a rocket plume when landing on the Moon, middle school students at Cliff Valley School in Atlanta, Georgia, tested the vibrations of the Xodiac rocket-powered lander using CO2 and vibration sensors. The team also used infrared (thermal) and visual light cameras to attempt to detect the hazards produced by the rocket plume on the simulated lunar surface, which is important to ensure a safe landing.

4. Rocket Navigation

Middle and high school students at Tiospaye Topa School in LaPlant, South Dakota, developed an experiment to track motion data with the help of a GPS tracker and magnetic radar. Using data from the rocket-powered lander flight, the team will create a map of the flight path as well as the magnetic field of the terrain. The students plan to use their map to explore developing their own rocket navigation system.

The 2024-2025 TechRise Challenge is now accepting proposals for technology and science to be tested on a high-altitude balloon! Not only does TechRise offer hands-on experience in a live testing scenario, but it also provides an opportunity to learn about teamwork, project management, and other real-world skills.

“The TechRise Challenge was a truly remarkable journey for our team,” said Roshni Ismail, the team lead and educator at Cliff Valley School. “Watching them transform through the discovery of new skills, problem-solving together while being driven by the chance of flying their creation on a [rocket-powered lander] with NASA has been exhilarating. They challenged themselves to learn through trial and error and worked long hours to overcome every obstacle. We are very grateful for this opportunity.”

Are you ready to bring your experiment design to the launchpad? If you are a sixth to 12th grade student, you can make a team under the guidance of an educator and submit your experiment ideas by November 1. Get ready to create!

I Saw Sam Altman's Iris-Scanning "Orb" In Brazil — And We Should All Be Scared As Hell

The initiative led by Open AI CEO Sam Altman to create a global identity system through iris scanning has landed in Brazil. But what about privacy, transparency and the ethical implications of such a vast biometric project?

I arrived late at the elegant house in the Vila Nova Conceição neighborhood of São Paulo, Brazil; the event was about to start. A handful of journalists were already gathered around a table with coffee, tea, cookies and snacks at the back of the house. But the tension was palpable; those tasked with "selling" the product to the press knew that they were facing a significant challenge.

When questions poured in — accompanied by few answers — it became increasingly clear that the Brazilian launch of World was prompting far more questions than applause.

Starting Nov. 13, World — an initiative created by OpenAI CEO Sam Altman — began scanning the eyes of Brazilians to add to a database that, according to the company, already contains biometric data from more than 7 million individuals. They started with 10 locations in the city of São Paulo — in shopping malls and with street stands.

I'll spare you the adjectives, because the story speaks for itself. Readers are welcome to use some of the concepts I usually use around in my column (techno-oligarchy, neocolonialism, techno-feudalism, etc.).

This is how World is currently promoting its work and purpose: it wants to create a global identity that ensures that the person using it is a human being.

The idea, conceived by founders Sam Altman, Alex Blania and Max Novendstern and financed from the outset by investor Andreessen Horowitz, responds to the growing difficulty computers face in verifying whether a user is a person or a robot. Essentially, with the evolution of AI, those captcha tests are becoming increasingly obsolete.

World created a machine called Orb — a black sphere designed to resemble something out of a science fiction movie — to scan each person's iris to provide them with a unique identity. According to an extensive report from BuzzFeed News, Orb uses a thermal scanner to check people's body temperature, a 3D camera to map faces, and high-resolution cameras to capture videos and images of bodies, faces and irises — all to prove that it is indeed a real person and not just a photo.

The biometric data is reportedly not stored by the organization; only encoded values known as hashes are kept across various servers at universities so that “the iris cannot be reconstructed.” We have to trust that this is true because, as with other tech companies, there is no oversight body that can verify if this promise is indeed fulfilled.

But the issue lies not only in the lack of transparency regarding how data is stored and destroyed or with whom the company shares it — with BuzzFeed's report indicating that World’s data-sharing contract allowed it to share user data with third parties as it saw fit.

The problem begins with the narrative that the organization wants to sell.

The different Mars Rovers and what we learned

Sojourner (1997)

First rover to successfully land on Mars. Defined by NASA as a "micro-rover" due to its small size, Sojourner had a speed of maximum of 0.4 meters pr. minute. It was active for about 80 days on the surface of Mars.

Sojourner carried three cameras, an Atmospheric Structure Instrument (Meteorology Package) and an Alpha Proton X-ray Spectrometer. There instruments.

From Sojourner, NASA learned about the surface and weather conditions of Mars.

Sojourner found rounded rocks at the landing site, which suggests that running water could have been on Mars. The radio-tracking of Pathfinder (mission name) also gave an estimate of Mars' metal core's size (1300 kilometers to 2000 kilometers). It also discovered that the dust that is in the air on Mars is magnetic and possibly made up of mahemite. Sojourner also observed dust devils, ice clouds in the lower atmosphere and temperature fluctuations on the surface of Mars.

Spirit (2004-2010) and Opportunity (2004-2018)

Spirit was one of two Mars rovers launched in 2003 (mission started in 2004). The wheels on Spirit and Opportunity were about double the size of Sojourners. The weight of both rovers was about 17 times Sojourners, and more than double the size. Their goal on Mars was to search the surface for traces of past water. In 2009, Spirit got stuck in soil (in the area called Troy). In 2010, Spirit stopped communications, and the mission ended in 2011.

Opportunity was launched in 2004 along with Spirit but lasted much longer than their twin. Setting the record for the longest-lasting Mars rover, Opportunity stopped communications in 2018. Opportunity also set the record for the longest distance traveled by a rover, around 45 kilometers.

Like Sojourner, Spirit provided data about Mars' weather conditions, especially the wind. Both Spirit and Opportunity found evidence of possible conditions on Mars that could allow microbial life.

Spirit and Opportunity both had panoramic cameras, a thermal emission spectrometer, a Moessbauer spectrometer, an alpha particle X-ray spectrometer, and a microscopic imager.

Curiosity (2012-present)

Curiosity is currently the oldest active Mars rover (as of 21/07/2023) The main purpose of Curiosity is to figure out if Mars has the right environment for microbial lifeforms. Curiosity is currently exploring Gale Crater and had the most advanced instruments at the time. Curiosity has found evidence of water having been on Mars in the past, found old organic material, and discovered that Mars has had a thicker atmosphere in the past.

Curiosity can climb over knee-high obstacles and can go up to 30 meters per hour.

Curiosity carries a radioisotope power system to generate electricity, which gives the rover a steady electricity flow. Curiosity also carries 17 cameras, a laser, a drill, and 10 different instruments.

Perseverance (2021-present)

Perseverance is the newest Mars rover from NASA. The main goal for Perseverance is to research habitable conditions on Mars, but also for signs of past microbial life. The mission also tests possible options for future human expeditions on Mars (ex. improved landing techniques, producing oxygen from the atmosphere and environmental conditions).

The drill Perseverance used can collect samples and then set them aside for collection on the surface.

Zhurong (2021-2022)

Launched by the CNSA, Zhurong is the first Chinese Mars rover. In 2022 it became inactive due to sandstorms and the winter, which prevented it from waking at an appropriate temperature and good sunlight conditions.

Zhurong's mission was to study the topography, examine the surface (soil and elements), and take samples of the atmosphere. To do this it had a RoPeR (Mars Rover Penetrating Radar), RoMAG (Mars Rover Magnetometer), MCS (Mars Climate Station), MarSCoDE (Mars Surface Compound Detector), a multispectral camera and navigation and topography cameras. It also had a remote camera on board.
