Hydrogen Rockets: The Key to Sustainable Space Exploration
Introduction to Hydrogen Rocket Engine
In the realm of space exploration, the quest for efficient propulsion systems has led to the development and utilization of hydrogen rocket engines. These engines harness the power of hydrogen, the most abundant element in the universe, to propel spacecraft into the cosmos with remarkable efficiency and power.
History of Hydrogen Rocket Engine Development
The concept of using hydrogen as a propellant dates back to the early days of rocketry. However, it wasn't until the mid-20th century that significant advancements were made in the development of hydrogen rocket engines. Pioneering work by scientists and engineers paved the way for the modern hydrogen propulsion systems we see today.
How Hydrogen Rocket Engines Work
Fuel Combustion Process
Hydrogen rocket engines operate on the principle of combustion. Liquid hydrogen is combined with liquid oxygen in a combustion chamber, where it undergoes a controlled explosion. This rapid combustion generates intense heat and pressure, producing a powerful stream of hot gases.
Thrust Generation
The expulsion of these hot gases through a nozzle at the rear of the rocket creates thrust according to Newton's third law of motion. This thrust propels the rocket forward, overcoming the forces of gravity and atmospheric resistance.
Advantages of Hydrogen Rocket Engines
Hydrogen rocket engines offer several key advantages over conventional propulsion systems:
High Efficiency: Hydrogen boasts one of the highest specific impulse values among rocket propellants, making it extremely efficient in terms of thrust per unit of propellant mass.
Clean Combustion: The combustion of hydrogen with oxygen produces water vapor as a byproduct, resulting in cleaner emissions compared to traditional rocket fuels.
Abundant Resource: Hydrogen is abundant in the universe, making it a sustainable and readily available resource for space exploration endeavors.
Challenges and Limitations
Despite its many advantages, hydrogen rocket technology also faces significant challenges and limitations.
Cryogenic Storage
One of the primary challenges associated with hydrogen rocket engines is the need for cryogenic storage. Liquid hydrogen must be kept at extremely low temperatures to remain in a liquid state, requiring specialized storage and handling systems.
Cost and Infrastructure
The infrastructure required to produce, store, and transport liquid hydrogen adds to the overall cost of hydrogen rocket technology. Additionally, the development of hydrogen propulsion systems necessitates substantial investments in research and development.
Applications of Hydrogen Rocket Engines
Hydrogen rocket engines find a wide range of applications in space exploration and satellite deployment missions.
Space Exploration
Hydrogen-powered rockets enable spacecraft to travel vast distances across the solar system, facilitating missions to explore distant planets, moons, and celestial bodies.
Satellite Deployment
The high efficiency and reliability of hydrogen rocket engines make them ideal for launching satellites into orbit around the Earth and beyond.
Comparison with Traditional Rocket Engines
Compared to traditional rocket engines fueled by kerosene or solid propellants, hydrogen rocket engines offer superior performance and environmental benefits. They deliver higher specific impulse and produce cleaner emissions, contributing to a more sustainable approach to space exploration.
Environmental Impact and Sustainability
The environmental impact of hydrogen rocket engines is relatively minimal compared to conventional propulsion systems. The use of hydrogen as a fuel results in cleaner combustion and reduced greenhouse gas emissions, aligning with efforts to mitigate the environmental footprint of space exploration activities.
Future Prospects and Developments
As technology advances and our understanding of hydrogen propulsion deepens, the future holds great promise for hydrogen rocket engines. Ongoing research and development efforts aim to enhance efficiency, reduce costs, and overcome existing limitations, paving the way for new frontiers in space exploration.

SAUVAGE.
jupiter, you’re hard (to get).
sum. jupiter may not smell like woody ambery trails or smoky accents, and he may seem like just a really big planet who’s really far away, but juno will always find him.
wc. 3.2k
cw. spacecrafts, stars, and planets, roman mythology, kudos to sabrina carpenter’s juno, producer!reader x idol!han, friends2lovers, a beer (if i must content warn you, i will) smut! car! heavy on kisses with a side of unprotected piv sex (don’t!) switch!jisung x switch!reader (undefined tbh)
scent. (♡) the perfume saga.
[🔺☆ 🚀 ☆🔺]
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
It is a gas giant with a mass more than two times that of all the other planets in the Solar System combined, and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth, and a tenth that of the Sun. Its name derives from that of Jupiter, the chief deity of ancient Roman religion. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years.
However, Han Jisung isn’t quite as big or gaseous. He likes to believe he isn’t made up of metallic hydrogen, but rather stardust, he had said once —and you remembered, of course, because how couldn’t you—. He isn’t the oldest planet in the Solar System. He doesn’t run hotter than the Sun. He doesn’t have many many moons (95!) that spend ages to rotate around him.
Well. Not moons, anyways.
Juno is a NASA space probe orbiting the planet Jupiter.
It was built by Lockheed Martin and is operated by NASA's Jet Propulsion Laboratory. Juno entered a polar orbit of Jupiter in 2016 to begin a scientific investigation of the planet. After completing its mission, Juno was originally planned to be intentionally deorbited into Jupiter's atmosphere, but has since been approved to continue orbiting until contact is lost with the spacecraft.
Thing is. You’re not a spacecraft either. You weren’t built by whoever Lockheed Martin is. You can’t orbit around planets. And most definitely, you don’t keep in contact with NASA. Nevertheless, a part of you can’t help but relate, because, somehow, even after your mission was ultimately done, you couldn’t stop orbiting around Jupiter.
Well. Not Jupiter, anyways.
you: let’s do some cardio next day
jisungie🎀💫: cardio, you say? 😏
jisungie🎀💫: not even a coffee before taking me to your place? 🤨📸
Jupiter couldn’t even reach to make you feel the giddiness that Han somehow could trigger and make it overcome you. You kicked your feet, but when you entered and found your reflection in the elevator mirror, you clicked your tongue.
“Don’t be such a schoolgirl”, you mumbled to yourself, pressing the button, and heading up back home.
you: tsk tsk, you’re always thinking about food
And you’re always thinking about him, a mean voice in your head snapped back at you. You cursed, damning your own mind for betraying you. But, to spare you, it wasn’t that serious, you thought. You two interacted just the right amount.
He was an idol, for god’s sake. You weren’t catching feelings. That would be dumb on your side, the least.
So of course, when your phone chimes in the specific ringtone that, of course, you hadn’t set just for his contact, of course, you didn’t almost drop your purse when you read what he replied.
jisungie🎀💫: as if, silly
jisungie🎀💫: i ain’t eating no one for free
The text made you dizzy, so you forced yourself to back off from replying the first thing that came to mind.
Hungry? Eat me.
“Think straight for once,” you cursed out loud, passing your hands through your hair. Closing the door to your apartment and knocking your shoes off while your mind went off to other, far more interesting places and memories.
You clearly remembered the moment you met quirky, loveable Han Jisung. How inevitable it had been to just start orbiting around him with the excuse of your mission— producing one of his solos for an upcoming skz-record.
Headphones. It had been such a silly first encounter, yet so fitting for you two that you couldn’t help but cherish it dearly.
Lost in thought, you hadn’t been paying attention to where you were headed. Neither had he, and, which had ended with a little crash against each other. A meteor, not quite as devastating as so to kill a couple dinosaurs, but to leave a crater in your heart and create a small moon out of the pieces that scattered away shyly.
“Sorry!” You bowed your head, then stared at him.
“Hi,” he had said in a sheepish tone, hints of panting that you attributed to how he must’ve run back in hopes of catching you. “Guess you like wave to Earth too?”
And while he giggled, you told yourself you weren’t going to fall, but both Jupiter and Juno knew.
They had said the same thing about Rome.
jisungie🎀💫: entering jyp
you: at 21:43? jeez
jisungie🎀💫: what? i ain’t afraid of success bbg 💪
jisungie🎀💫: come over if you want
What would happen with any other person was that they’d smile and turn off their phone.
Well. Not Juno.
Not you, no.
[🔺☆ 🚀 ☆🔺]
The studio smelled like bubble tea, and that’s how you knew he was still there.
“Oh, hey! I wasn’t sure if you were coming in.” Han smiled.
Sleepiness oozed off of him, and you grinned, cleaning the table from leftover crumbles as you set your bag down. Your heart twirled imaginary hairs when Jisung’s hands —hands with several rings, something that could sometimes be a lot to manage— left the keyboard and settled on his thighs, softly stroking them as he turned the chair to face you.
“Yeah. Wanted to work on a demo I owe to the girls,” you mentioned, taking your jacket and your mask off.
“Actually,” he started, and your hands tingled with the feeling that you’d help him in whatever he needed. Damnit, hands. Damn you, heart. “Could you help me with this demo? Jeonginnie asked me to go over it.”
You sipped from your own drink, as if to fake giving it a bit of a thought. You were going to say yes, of course. But instead, you scratched your arm, frowning lightly.
“Innie asked you?”
“It’s for his solo stage.” He clarified, turning back to face the computer. “We all have them for our tour.”
The way he entered the recording booth seemed distant, and a part of you couldn’t help but wonder why as you fidgeted with your necklace and settled everything on the desk comfortably. Ji turned the light off, something slightly weird. He never did that with you, after all these years, and considering you two were the only ones there, you asked.
“Is it a high register?” You wondered, pressing the button on your left so he could hear you in his headphones. You blinked when you saw his figure slightly jolt in something like surprise.
“Uh, no. It’s just the… style of the song,” he giggled, putting his beanie on and tucking in the hairs that fell over his eyes.
Oh. That’s the one you gifted him.
“Sure. Mind if I give it a listen first?”
“Go ahead,” he replied without looking at you through the window.
Helping him came off naturally. The track for the girls was an excuse, one you had already forgotten. And as he started singing, you weren’t sure you’d remember any time soon.
“T-those are some bold lyrics, huh?”
Hallucination.
Jisung covered his eyes with his beanie, giggling.
“It’s Innie’s fault. He gets it from Chan.”
“What’s Chan’s solo about?” You asked with a laugh.
You didn’t expect Jisung to stare at you and swallow dry.
“He says it’s about trains.” He shrugged, as if he had remembered suddenly that he was supposed to answer your question.
When you both were done, it was late. Really late. He insisted you two grabbed a beer in the convenience store nearby, but you took a juice, claiming you had to drive.
“I’ll uh, I’ll get the bus, seriously,” he raised his hands as you both exited the store, beer in hand.
“Ji,” you deadpanned, finishing your juice. Thank God you liked him, because sometimes you wanted to hit him. Softly. With a pillow. “Shut up. I’m taking you.”
[🔺☆ 🚀 ☆🔺]
“How come I didn’t remember you have a driver's license?” Han smiles sheepishly.
The drive to his apartment is silent, as if you two were submerged in a no-conversation. No words, no nothing, just the sound of the tires against the asphalt and the yellow lights from the streetlights that lightened your way.
It’s late enough that there are little to no cars on the driveway. But weirdly, Jisung sips from his beer and sighs.
“Actually, could to take a left here?” He says softly, his voice surprisingly low.
“That’s not the way to your apartment, is it?” You ask, as softly as him, turning anyways.
“Nah, it’s this place I found and I wanted to show you.”
Alcohol doesn’t get easy to him —not from a beer, at least—, but he’s smiling like silly, and you can’t help but smile too.
You park where he tells you, and surely enough, there’s no one there. It’s a secluded, empty area, far from the center and high enough so that the city can be seen clearly.
“Think I left my jacket here last time I came.” He snickers, and you can’t help but chuckle. His hand travels to your knee and he squeezes it gently. “I’ll come back in just a second.”
One blink. Two blinks.
Hot fucking damn.
Your head falls against the steering wheel as soon as he closes the door.
Get your shit together.
Looking up, the car tells you it’s way past midnight. Your head tells you you’re crazy, your heart giggles at the fact, guilty as charged. Sighing, you raise your face enough to look at the stars. Only to find Jisung’s silhouette, now with a dark jacket on, waving at you as he stands in front of the car.
You’re blushing, but you wave haphazardly, smiling, and still frown when instead of getting back to his seat, Jisung goes and opens your door instead.
“Hey,” he giggles, and your grin matches with his.
“What are you doing?”
Jupiter can sometimes be seen from Earth, when the Sun’s light hits it just right and the night is dark. Still, its shimmer doesn’t compare to that of Jisung’s eyes when he rests his forearms on the car’s roof and bends down to your height. You haven’t moved, your own eyes fixated on how he licks his lips.
“I think I’m being stupid,” he chuckles. You’re a goner, not even noticing how his hand slides in for a moment and turns the headlights off, leaving you two only illuminated by the shy light in the car that indicates that the door is open and by the moonlight, who cheekily shines at the both of you.
Instead, you blink. Normally you just get him, just as he gets you, but you’re almost as lost as how you feel when you stare into his dark brown eyes.
“Stupid?” You smile lightly. “Why?”
At your tender tone, Jisung lets his head fall down, shyness getting the best of him. And yet the little alcohol he’s had boosts him back.
“I, uh, had a dream. Been having these dreams for like, a bit over a month,” he swallows dry, much like he did at the studio, and his eyes suddenly feel darker than before, maybe because his gaze stops avoiding yours for longer than a minute.
A meteor shower threatens to fall over your heart.
“You were there. And I was there, too.”
For someone who composes and uses words for a living, he was struggling a lot to piece together what he wanted to say.
“This… there was… this… feeling, like, inside of me. Here.”
Not only does he not use his hand, but he takes yours from the steering wheel and settles it over his chest. His heart.
You’re frozen. Completely out of it. Is it possible that maybe you fell asleep in the studio and that none of this is real? Could that be it, you wonder, until Jisung groans and leans his forehead against the roof of the car with a thud.
“I’m being an idiot, am I?” He snickers, with an undertone that lingers in something that resembles resignation. “I just- I saw you the other day, and I was… you were with Hyunjin, and I…” he clenches his fist, and he tries to back off, rubbing his face and passing them through his hair.
“No, Ji, wait.”
He chuckles breathlessly. “I made it awkward, right?”
“Ji.”
Your hand pulls him back closer by the zipper of his jacket, and only the crunchy-like sound of the gravel beneath him as he walks echoes through the night and follows how you move your hands toward his wrists. Towards his own hands, stopping him from picking on his nails further.
“Tell me, Ji,” you mumble. “What were you saying?”
His voice threatens to tremble before he speaks. His eyes don’t move from yours, and you think you’re completely out of your mind, just as much as he thinks of himself too.
“I keep having these dreams where I see you and the ache of wanting you swells up in me, like I’m on a raft that’s sinking and I just can’t even escape thinking about you when I sleep because I-”
He’s rambling, but with a sudden move from your side, he’s not anymore.
The cold of November doesn’t hit you when you stand up bluntly and you link your arms behind his neck and kiss him like you have been wanting to do for years.
His lips crash against yours like the sea crashes against the sharp rocks against the shore, even if the coast is much further away than you think, but you don’t mind, because you can’t think.
You’re kissing him. Finally.
You’re kissing Han Jisung.
And then, just a beat after what you’ve done —what you’re doing— sinks in, he reacts. His hands travel underneath your jacket and in the blink of an eye, he’s letting you push him against the car. No words, no nothing, only the scent of his cologne that suddenly fills you.
You tremble beneath him, and he pants.
He’s not blinking, his eyes glued to you. He can’t think either.
You should say something. What should you say? ‘Me too’? That’s lame. How come your brain can’t work when you most need it?
As if to answer your question, Han kisses you this time. Of course you can’t think, not when his hands travel underneath your clothes and he twists you in a way that somehow it’s your back against the car now. He’s not breathing, and neither are you, because you’re not kissing anymore, not when your lips can feel the teasing dent of his teeth nibbling on them and when the only thing you can taste is his tongue.
You’re not against the car anymore, because he closes the driver’s door with a kick and he opens the one to the backseats while he keeps kissing you.
Crazy. You’ve gotta be, because dreaming something as wild as this and for it to feel real, as real as it gets, as real as it could ever be, it has to mean you’re crazy. And you’d die on that hill if it means you get to keep dreaming how Jisung takes his newly-found jacket off and throws it to the front seat, in the same foreign path as where he throws his shirt, or how you two barely fit in the car and so he settles his knee between your legs to help you move back enough so that he can close the door.
And now you’re there. Alone together.
He gasps against your neck, as if he remembered that he had to keep breathing to live, and you don’t lose your opportunity, taking your sweater off and throwing it towards the trunk.
You lean your head back, the car feeling heavy with only the sounds of both him and you panting.
“I… fuck, I need you to tell me you want this.” Han swallows dry. “I need you to say it. Please. I want this too much.”
A meteor shower? Scratch that. This is a meteor storm.
“I think this is a dream, but still, I want you. Please.”
No words, no nothing, just the sound of the leather against your sweaty skin when you sit up straight and kiss Jisung like you mean it. It’s all nasty, teeth and tongue and a string of saliva that lingers when you break the kiss to fumble with his zipper.
“What if it is a dream,” you gasp, out of breath, out of control, completely and irrevocably out of it as your eyes stare at his. “I want you. Even if I wake up right now.”
Your shirt is discarded as fast —if not faster— than the rest of your clothes before.
“So if it is a dream, let’s keep going until we wake up.” You swallow dry too. “Until the stars can’t be seen.”
The kiss is like a heroin kick, although it is one that seems familiar. Or maybe it’s that your lips have become used to kissing his, considering that breathing has become a second priority with how raw is the need to consume him. A wave of pleasure takes claim inside of you with each caress of his tongue, with every touch of his fingers on your back, with every eager breath next to your jaw. He pulls you closer and moans with his mouth buried in your skin unfinished phrases that drive you crazy little by little —more than you already were.
“It may end right away,” Jisung says in a hoarse voice, clinging to one of the headrests that are closest to him. “But I’ll make it up to you. With my mouth. Or with my fingers. Or both. Yes, fuck...”
It’s a mix of quick and ruthless kisses, mouths open. Wet and urgent, almost in bites, as if you’d want to eat the other alive as he takes his pants off and helps you with yours, going down to kiss your neck.
“You’re so... f-fuck, ah...” he mumbles while he runs his tongue down your throat and to your collarbone. “I never want to wake up.”
His lips taste like the feeling that overcomes you when you look at the sky on a starry night. Emotion. Ecstasy. You want to drink it whole until there’s not a single drop left. Drink him.
Jisunh squeezes your ass, while your mouths are a mess, while he bites your lip and pulls it, smiling like a cheeky bitch, while your mouths fight for the control of the kiss and your tongue caresses his, and before you can piece together that the windows are foggy because of the two of you, he’s sliding inside, his hand lacing with yours.
God, you want to moan. Moan so loud. And so you do, because there’s nothing in this dream that could stop you.
And he moans, too, because you are like a dream come true.
Juno and Jupiter.

TLT World Building: The Nine Houses and the Logistics of Space Empires
Building off my earlier post about stele-and-obelisk travel and the River, I wanted to talk about something that's been rattling around my mind for a while, which is subluminary travel and the logistics of the Nine Houses. One of the things that has been brought up as a criticism of Muir's world-building as far back as Gideon the Ninth is that the Empire seems to have very, very fast non-FTL travel, such that Gideon and Harrow travel the 3.3 billion miles from Pluto to Earth in an hour, without using a stele. How, it was asked, does an Empire whose military relies on swords and whose medical knowledge is incredibly uneven at best, accomplish a technological feat of that magnitude?
I think we got an answer for that in Nona the Ninth:
“That ship’s not big enough for a stele. Don’t know if it’s big enough for subluminary travel, even. How did it get here?” Crown leant back in her chair, staring at the projector screen, head balanced in the crook of one golden arm. Nona noticed that her biceps showed even through her shirt, and that there were rubber bandages wrapped around one palm. She said, “Oh, that’s big enough for subluminary travel, Millie. See the double struts, and the massive exhaust? That’s a Ziz-class.” ...Crown continued, “The Ziz isn’t Cohort standard. And it’s not as big on the inside as you think. Look at the windows—see how there’re none on the back end? It’s mostly engine. Not plated either. It’ll get to sublume without many problems … but it definitely doesn’t have room for a stele. Camilla is right. It can’t travel by obelisk anchor.” Pyrrha said suddenly, “Crown. How’s the fuel consumption on a Ziz-class ship?” “Thirsty,” said Crown, brightening up at being asked. “Its cell would be totally drained after a day in subluminary. It only takes the powerful stuff too—thalergy-enriched, not just hydrogen blend. Hydrogen blend stuffs up the engine.”
The answer is necromancy. (Because of course it is.) The Empire infuses shuttle fuel with thalergy - and we know that the necromantic specialty of the Second House is to "drain thalergy from any living source and use it," so the Empire can treat thalergy as a fungible resource that they can extract, store, and then use somewhere else. Moreover, we know that the necromantic specialty of the Fourth House is "exciting thanergy into a state of fission" in order to produce explosions.
Since necromancy can easily convert thalergy into thanergy, I think that the Empire's higher-end shuttles are powered by necromantic pulse propulsion, such that shuttle fuel is burned to produce thrust, but then at the same time the thanergy is turned into a massive fission explosion behind the shuttle, producing even more thrust.
I think this also explains why the Second and Fourth are so disproportionately represented in the Cohort, because in addition to producing soldiers for the front lines, they're heavily involved with making the Cohort Fleets move. (I'm going to further speculate that the Fourth make up a lot of the Fleets' pilots, since that would fit their necromantic specialties, the nature of their planet, and their image as gung-ho "go fast" types.) This leads me to a few conclusions:
it explains why the Empire is so focused on short-term extraction; it's essentially stripping the thalergy for fuel to power subluminary transportation in the Dominicus system and beyond, in the same way that we're burning fossil fuels to power our economies today. There is a profound irony in that Mr. Environmentalist John Gaius has so precisely recreated the dynamics of the carbon economy through necromancy.
it explains how logistics in the Nine Houses work. If you can use necromantic fission drives to get from the outer edge of the Dominicus system to the core that quickly, than most of the logistical complexities of running a multiplanetary economy fall away. All you have to do is get your transport shuttle full of goods from the colonies to a stele at the edge of the Dominicus system, and then necromantic fission solves the "last mile problem" of getting your Necro-Amazon "just-in-time" deliveries to the hungry markets of the Third or the Fifth. You don't need to worry about the fact that you can't produce a lot of organic resources on thanergetic planets (especially ones that are space stations and the like rather than fully terraformed), because you just have everything delivered.
it similarly explains how logistics out in the colonies work. Even if you're at the edge of the stele network, necromantic fission shuttles can transport goods between planets in the same solar system with relative ease. It only becomes an issue when you're a ways out from the edge of the network, because that involves burning more thalergy-enriched fuel. Hence why Corona talks about "the Cohort movements didn’t make sense to her...shepherd planets got more costly the further the Houses extended themselves."
This makes me think of necromancy in a different way than I had before. Rather than just being about magic and warfare, necromancy is essentially the technology of the Nine Houses (aside from some legacy technologies that they have left over from pre-Resurrection), the tool that they use to solve all of their problems and make their society and economy and government function.

IS THE MOON RUSTING??
Blog#309
Wednesday, June 28th, 2023
Welcome back,
While our Moon is airless, research indicates the presence of hematite, a form of rust that normally requires oxygen and water. That has scientists puzzled.
Mars has long been known for its rust. Iron on its surface, combined with water and oxygen from the ancient past, give the Red Planet its hue. But scientists were recently surprised to find evidence that our airless Moon has rust on it as well.
A new paper in Science Advances reviews data from the Indian Space Research Organization's Chandrayaan-1 orbiter, which discovered water ice and mapped out a variety of minerals while surveying the Moon's surface in 2008. Lead author Shuai Li of the University of Hawaii has studied that water extensively in data from Chandrayaan-1's Moon Mineralogy Mapper instrument, or M3, which was built by NASA's Jet Propulsion Laboratory in Southern California. Water interacts with rock to produce a diversity of minerals, and M3 detected spectra - or light reflected off surfaces - that revealed the Moon's poles had a very different composition than the rest of it.
Intrigued, Li homed in on these polar spectra. While the Moon's surface is littered with iron-rich rocks, he nevertheless was surprised to find a close match with the spectral signature of hematite. The mineral is a form of iron oxide, or rust, produced when iron is exposed to oxygen and water. But the Moon isn't supposed to have oxygen or liquid water, so how can it be rusting?
The mystery starts with the solar wind, a stream of charged particles that flows out from the Sun, bombarding Earth and the Moon with hydrogen.
Hydrogen makes it harder for hematite to form. It's what is known as a reducer, meaning it adds electrons to the materials it interacts with. That's the opposite of what is needed to make hematite: For iron to rust, it requires an oxidizer, which removes electrons. And while the Earth has a magnetic field shielding it from this hydrogen, the Moon does not.
"It's very puzzling," Li said. "The Moon is a terrible environment for hematite to form in." So he turned to JPL scientists Abigail Fraeman and Vivian Sun to help poke at M3's data and confirm his discovery of hematite.
"At first, I totally didn't believe it. It shouldn't exist based on the conditions present on the Moon," Fraeman said. "But since we discovered water on the Moon, people have been speculating that there could be a greater variety of minerals than we realize if that water had reacted with rocks."
After taking a close look, Fraeman and Sun became convinced M3's data does indeed indicate the presence of hematite at the lunar poles. "In the end, the spectra were convincingly hematite-bearing, and there needed to be an explanation for why it's on the Moon," Sun said.
Their paper offers a three-pronged model to explain how rust might form in such an environment. For starters, while the Moon lacks an atmosphere, it is in fact home to trace amounts of oxygen. The source of that oxygen: our planet.
Earth's magnetic field trails behind the planet like a windsock. In 2007, Japan's Kaguya orbiter discovered that oxygen from Earth's upper atmosphere can hitch a ride on this trailing magnetotail, as it's officially known, traveling the 239,000 miles (385,00 kilometers) to the Moon.
That discovery fits with data from M3, which found more hematite on the Moon's Earth-facing near side than on its far side. "This suggested that Earth's oxygen could be driving the formation of hematite," Li said. The Moon has been inching away from Earth for billions of years, so it's also possible that more oxygen hopped across this rift when the two were closer in the ancient past.
Then there's the matter of all that hydrogen being delivered by the solar wind. As a reducer, hydrogen should prevent oxidation from occurring.
But Earth's magnetotail has a mediating effect. Besides ferrying oxygen to the Moon from our home planet, it also blocks over 99% of the solar wind during certain periods of the Moon's orbit (specifically, whenever it's in the full Moon phase). That opens occasional windows during the lunar cycle when rust can form.

NASA’s Webb Peers into the Extreme Outer Galaxy
Astronomers have directed NASA’s James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For comparison, Earth is approximately 26,000 light-years from the center.)
A team of scientists used Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) to image select regions within two molecular clouds known as Digel Clouds 1 and 2. With its high degree of sensitivity and sharp resolution, the Webb data resolved these areas, which are hosts to star clusters
undergoing bursts of star formation
, in unprecedented detail. Details of this data include components of the clusters such as very young (Class 0) protostars, outflows and jets, and distinctive nebular structures.
These Webb observations, which came from telescope time allocated to Mike Ressler of NASA’s Jet Propulsion Laboratory in Southern California, are enabling scientists to study star formation in the outer Milky Way in the same depth of detail as observations of star formation in our own solar neighborhood.
“In the past, we knew about these star forming regions but were not able to delve into their properties,” said Natsuko Izumi of Gifu University and the National Astronomical Observatory of Japan, lead author of the study. “The Webb data builds upon what we have incrementally gathered over the years from prior observations with different telescopes and observatories. We can get very powerful and impressive images of these clouds with Webb. In the case of Digel Cloud 2, I did not expect to see such active star formation and spectacular jets.”
Stars in the Making
Although the Digel Clouds are within our galaxy, they are relatively poor in elements heavier than hydrogen and helium. This composition makes them similar to dwarf galaxies
and our own Milky Way in its early history. Therefore, the team took the opportunity to use Webb to capture the activity occurring in four clusters of young stars within Digel Clouds 1 and 2: 1A, 1B, 2N, and 2S.
For Cloud 2S, Webb captured the main cluster containing young, newly formed stars. This dense area is quite active as several stars are emitting extended jets of material along their poles. Additionally, while scientists previously suspected a sub-cluster might be present within the cloud, Webb’s imaging capabilities confirmed its existence for the first time.
“We know from studying other nearby star-forming regions that as stars form during their early life phase, they start emitting jets of material at their poles,” said Ressler, second author of the study and principal investigator of the observing program. “What was fascinating and astounding to me from the Webb data is that there are multiple jets shooting out in all different directions from this cluster of stars. It’s a little bit like a firecracker, where you see things shooting this way and that.”
The Saga of Stars
The Webb imagery skims the surface of the Extreme Outer Galaxy and the Digel Clouds, and is just a starting point for the team. They intend to revisit this outpost in the Milky Way to find answers to a variety of current mysteries, including the relative abundance of stars of various masses within Extreme Outer Galaxy star clusters. This measurement can help astronomers understand how a particular environment can influence different types of stars during their formation.
“I’m interested in continuing to study how star formation is occurring in these regions. By combining data from different observatories and telescopes, we can examine each stage in the evolution process,” said Izumi. “We also plan to investigate circumstellar disks
within the Extreme Outer Galaxy. We still don’t know why their lifetimes are shorter than in star-forming regions much closer to us. And of course, I’d like to understand the kinematics of the jets we detected in Cloud 2S.”
Though the story of star formation is complex and some chapters are still shrouded in mystery, Webb is gathering clues and helping astronomers unravel this intricate tale.
These findings have been published in the Astronomical Journal
IMAGE: Scientists used NASA’s James Webb Space Telescope to examine select star-forming areas in the Extreme Outer Galaxy in near- and mid-infrared light. Within this star-forming region, known as Digel Cloud 2S, the telescope observed young, newly formed stars and their extended jets of material. This Webb image also shows a dense sea of background galaxies and red nebulous structures within the region. In this image, colors were assigned to different filters from Webb’s MIRI and NIRCam: red (F1280W, F770W, F444W), green (F356W, F200W), and blue (F150W; F115W). Credit NASA, ESA, CSA, STScI, M.

HIII! I’ve been obsessing over your starships, they are truly staggeringly beautiful. I must know your style guide, or references! I am building my own artistic background and your stylized design is so… pointy and Victorian and shit. I MUST know! How does it WORK!
Tunguska is a giant root vegetable covered in ship hull texture. It's a cone because that's what physics says the optimal warship is. The radiators were supposed to explicitly evoke the masts, wires and ropes you'd find on ships.
Navikea is more of a mix of trains and tractors. There's no armor so it's all naked function - big boxy cargo bay, ring habitat, giant hydrogen cisterns (physics says you need them) and then just the propulsion part.
Both of them have radiators and engines based on real proposals.
It helps to reference everything but the thing you wanted to make. So, if you want to draw a spaceship, have references that aren't other artists' spaceships. Or even real spaceships.

"Rockwell concept for an air-launched spaceplane produced as part of the Advanced Military Spaceflight Capability study."
"In December 1980, Don Hart of the Air Force Rocket Propulsion Laboratory at Edwards Air Force Base wrote a memo describing a proposed Air Force Space Sortie Vehicle that would be launched from the back of a 747. Ehrlich says that he knew Hart at the time, and that it is possible that Hart got the idea of the Space Sortie Vehicle concept from some work that Rockwell was then engaged in. “I’m not sure which came first, Don’s or ours, or they may even have been shared concepts,” Ehrlich remembers. He said that around 1978 or ’79 the Air Force was interested in a concept that they then called 'On-Demand Launch.' Rockwell learned of the Air Force interest and began working on several concepts. In 1979, the Air Force initiated an Advanced Military Spaceflight Capability Technology Identification Study (known as AMSC) and Rockwell was ready for it. The AMSC study actually preceded and ran concurrently with the Air Force Space Sortie Vehicle outlined in Hart’s December 1980 memo.
Ehrlich had taken his lifting body knowledge with him to Rockwell. The FDL-5A shape seen pulled out of the C-5 in the artist impression is the more angular version, with the single tail. But when Rockwell started working on the AMSC, they considered a spacecraft with drop tanks and mounted above a 747. The shape they used in that study was the more rounded version, with winglets. 'Different mission, different shape, but retaining the critical aerodynamic features which were key,' Ehrlich explained. The craft could be wider because it did not have to fit inside an aircraft. The Rockwell craft also had three rocket engines in its tail.
The Rockwell approach was to use the V-shaped drop tank only for hydrogen. The spacecraft itself would carry both oxygen and a little bit of hydrogen for the final push into orbit. This simplified the tank design, and since the tank was the expendable part of the spacecraft that reduced cost.
But Rockwell ran into the same limitations experienced by other companies that looked into the Sortie Vehicle Concept. Such a craft could only carry a relatively small payload. But it also required drop tanks, and that increased the expense. The Air Force wanted a cheaper vehicle and the only way to achieve that would be to develop one that was fully reusable."

Cool little animation I made of an alien creature that utilizes endogenous hydrogen gas to fly! Kinda like Kirby, but I guess biologically plausible??? Maybe??? Probably, I dunno. But yeah!
These guys are called the Tik'ltia, and they originally evolved from 9-limbed pack-hunting cephalopod-like animals.
More info under the read more!
In the oceans, they used the hydrogen produced inside their digestive systems as a sort of jet propulsion boost, either to escape larger predators, or to quickly ambush prey. They have very potent venom, potent enough to kill 200 adult men!
Yikes, that's pretty deadly!
As they eventually moved onto land, the first pair of fins on their heads became sort of multi-purpose structures, using them as pinnae for better hearing, wing-ish structures to gain altitude, and also to balance when in the air.
Their second pair of fins turned into their hands, of course. Their eight front tentacles fused on each side, becoming sort of like paws.
And their ninth tentacle became a kind of weird tail-limb thing that they can grab stuff with.
They have two siphons, one under each of their eyes. They also have chelicerae to inject the venom with, which are hidden within their mouths. When relaxed, they are curled up, resembling the mouth of a cat on the outside.
Due to the conditions on land being a lot colder than on earth, they had to quickly find a way to stay on land without dying of hypothermia.
And what better way to stay warm than to get a nice coat of fur?
Well, in this case, it's more like setae. But still, good insulation! They're actually even fluffier than chinchillas, I might add!
When not in flight, they are only about the size of basketballs. Yes, very small...
By the way, they're still pack-hunting ambush predators. Now, they congregate to the skies, using their countershading as an advantage.
They stalk their prey for miles, flying silently overhead.
Then... They drop down, injecting their lethal paralyzing venom into the target, swiftly taking it down.
Also, they may or may not be a bit sapient... Heeheehee...

Inspired by this post by striderl, here are the explanations for my characters' serials.
Cygnus (5022)
Inspired by a Cheapshow (podcast) episode in which a character mangled some bingo calls, calling 22 as 'two little swans' instead of the traditional 'two little ducks'. Instantly I knew I had to use that for a character somehow: give them a serial ending in 22 and call them Cygnus (the genus of swans).
The 'Fifty' came later just because I liked the sound of 'Fifty-Twenty-Two'.
Phaeton (1842)
This one actually gets explained in-universe. As Phaeton is a human, they weren't automatically assigned a serial, so they had the opportunity to choose their own one. Phaeton chose 1842 because the atomic numbers of hydrogen, oxygen and molybdenum are 1, 8 and 42. The chemical abbreviations of those elements are H, O and Mo, which can be put together to spell Homo (the genus of humans).
In this way, Phaeton and Cygnus have 'matching' serials; Cygnus's name is an organic genus derived from their serial, whereas Phaeton's serial is digits derived from their organic genus.
Engineer 1668 (lead engineer on the TV Titan's maintenance crew)
It's the melting point (in degrees Celsius) of titanium. (Geddit, titan-ium?)
I wanted to use the Kelvin temperature because Kelvin seems more Science than Celsius, but 1668°C is 1941°K, and 1668 was just a more pleasing number.
Agent 1791 (TV Titan's identity pre-upgrade)
(Yes, the Titan's not actually my character, but [fart])
It's the year of discovery of the element titanium. (Although it was initially named maccanite, and didn't receive the name titanium until 1795.)
Primus (1153) and Icarus (1566) (TV Matriarch's bodyguards)
(Also not actually my characters. But also it appears to be fanon that these two are the Matriarch's bodyguards at all! We've never seen them since their first appearance.)
I devised their nicknames and serials concurrently; I wanted to give them serials that Phaeton could turn into nicknames.
I decided I wanted one of them to be called Primus, so I looked up 4-digit primes looking for one that was both 'pleasing' and was splittable into a pair of 2-digit primes.
For Icarus I looked up asteroid names and numbers until I found one that was both a reasonable character name and had a pleasing number.
Fornax (4304)
The number was just one I found pleasing. The hard part was later coming up with a nickname, after I decided I'd got attached to this character enough to name them.
I initially wanted to carry over Cygnus's theme of 'bird name that's also a constellation'. Unfortunately the birb constellations don't have terribly pleasing names. Besides Cygnus, there's Apus (bird of paradise), Aquila (eagle), Columba (pigeon), Corvus (crow), Grus (crane), Pavo (peafowl), Phoenix (not a real birb), and Tucana (toucan).
Corvus is admittedly kinda cool-sounding, but was a bit too close to Cygnus for my liking. I initially wanted to go with Grus, because I noticed that so far all my named TVs had names ending in -us (Cygnus, Primus, Icarus) and I wanted to continue that theme, but I just couldn't make myself like it as a name, plus it just didn't feel like something Phaeton would pick for them.
In the end I threw out the bird link and kept just the constellation link. Phaeton chooses Fornax as a name just because of that and because 'four' and 'for' sound similar.
(Fornax means 'furnace', and Phaeton means 'one who shines'. So the trio are basically called Shiny, Swan and Oven.)
Other engineers
I literally used random.org to generate numbers, and picked the first 15 that fulfilled my criterion of 'last digit can't be 0' (see link below for why not).
I wanted to give myself a little challenge of coming up with nicknames for existing numbers that I didn't pick, instead of picking numbers that would fit a specific name.
I ended up with two characters with serials ending in 07, so they'll get nicknames to tell them apart. 5007 and 9807 both work on the Titan's propulsion systems and are collectively referred to as 'the Sevens'; 5007 is nicknamed 'Stannum' (Latin for tin, which has atomic number 50) and 9807 is nicknamed 'Ianthe' (for the asteroid 98-Ianthe).
Engineer 9779 is nicknamed Palindrome for obvious reasons.
Unfortunately, one of the numbers random.org gave me was 6918. I considered not using that one, because people will likely assume I added the 69 to be funny, then I thought 'nah, just add it, things like this would be inevitable with procgenned serials'.
There are two engineers with nearly identical serials (because that happens with true randomness): 7672 and 7678. They'll probably get nicknames at some point.
That's the Doylist explanation. The Watsonian explanation of how TV serials are generated is in this post I made earlier this year.

silly WH40K inspired idea.
It's the year XXX in the future. A cabal of people exist that take up a paladin-esque role with elements of cowboyism and monastic trappings.
As part of the graduation, the prospective member of the order is provided the hand tools necessary to construct their own firearm. They must design it on paper and utilize simulator technology to prove the design is safe and capable of withstanding the brutalities associated with its own existence. Unwise decisions that result in the operator's self-harm or destruction of the firearm are possible, and politely discouraged.
But every member of the group effectively needs to be capable of being an engineer and gunsmith, able to turn raw ingredient metals into components for firearms and ammunition. The organization supplies the education necessary, and at least information on how to hand make the tools to make firearms, but it's ultimately up to the prospective gunsmith to smith them.
There'd also be an organization standard for firearm blueprints and ammunition size and case style. Exactly what, I don't know, but the organization's emphasis is on being able to make that exact kind of firearm almost anywhere on planet earth from locally available rocks, sunlight and parabolic mirrors (for the heat) and component molds.
There'd be a trial to just make Whatever Was Necessary to fire a bullet at a target to a minimum small arms range, and then exceptional marks are made for ranges exceeding the length of the curvature of the earth, and a separate trial to be able to make an Organization Standard Performance Rifle, out of materials ideal for that (assuming care would be taken to acquire the necessary materials, not just scrap together something that just has to survive firing a bullet once.)
Reason being is the continued education in the traditions of the personal firearm, as well as other force multiplier forms of weaponry, and the continued fabrication of such when you have a minimum of material components to work with. And yes, the implication such materials might be being bottlenecked and withheld from the public is not an accident, but the organization's trials and system assumes as much, that simple trade and procurement may not be possible or legal.
That's the lowest level member. Being able to make your own small arms is the minimum base requirements for initiation. Above those are the Large Arms makers. Kinetic weapons that are just really big guns that may or may not require multiple people to man. This includes everything from mortars, to howitzers, to artillery, to anti-air gun batteries. Whom similarly operate under the idea that the only way these things might exist in an area, is if they know how to personally manufacture and fabricate each and every component themselves.
Perhaps they have some process to work backwards and marry carbon with hydrogen to create propellants. Perhaps they eschew "messy" forms of propellants and use some custom material that is effectively just hydrogen, for light gas guns. That'd be neat. I'm not 100% sure. But I do know as the component of a kinetic weapon, it'd be another part of the manufacturing process of your own gun and ammunition.
Why light gas guns, specifically? Because when you use hydrogen as a propellant, it burns cooler (temperature-wise, I don't mean, 'that's cool/awesome') and has greater impulse. A person so inclined could literally fire a payload and escape the earth's orbit with it, while conventional propellants cannot do this. Hydrogen gas or liquid as a propulsion system means very very fast projectiles that can conceivably move so fast that they tear themselves apart in the atmosphere. When you need to fire something screaming and generating its own plasma out into space from the ground, but you can't use a railgun, you go to the Light Gas Gun guys.
Above them would be the Electropropulsion Systems. Yes, I'm talking railguns and coil guns. Due to the sheer complexity and investment in materials required for the magnets and armatures, considered somewhat impractical, but when you need absurd range and power and want a simpler propulsion system, you go to the coil and rail guys. A big advantage of these sorts of drive systems would be it's simply less high profile than components to create or transport hydrogen gas than it is electronic components.
And above them, would be the realm of computer scientists and electricians, because now the order gets into rockets and guided self-propelled projectiles. Requiring the organization's resources and manpower, they still standardize fabrication units to make the exact specified digital computer components needed to create missiles with the topological data and inertial drives to tell exactly where they are on earth at any given moment of time, and where they should be. No more computing power than is necessary to go as far as a missile of their size with the fuel that offers the greatest possible range to chemical science and physics and get it from where it's fired to where it needs to be. They do not rely on satellites (though the option may exist), they hard insulate the self-propelled projectiles against radio interference, give them a very detailed map and send them on their way.
Sitting atop the heap are the engineers and electricians and computer scientists for fire control systems for everything from large kinetic weapons like naval guns and artillery, as well as the guys behind the computers and component standards for missiles. Not just components of other specialty weapon types, but their own group in the organization, given how essential a standard and the science is for the function of other weapon types. They bear the standards on the absolute minimum material components and methods for fabricating the ideally sized and powered pieces, be they electro-mechanical, or digital. As a rule, for things that are made to resist neglect and the rigors of time, electro-mechanical things are preferred. For power and control and performance, refined and perfected digital fire control systems are ideal. Cartographers, map makers, cosmologists, everything one would need for obscenely accurate missiles ranging from lipstick tube sized to ICBMs.
And from there we get to limited robotics and machines for mobility. Terrestrial, legged or wheeled, flying, swimming. Drones. Turrets. Things that allow movement. Considered its own subset skill, it's added last only because it encompasses everything that comes before, and applies to all. That includes rockets and jets.
And, really. That's kind of all she wrote. Well, he. 'Cause, I wrote it, and I'm a cisgendered dude. Once you get to the point you've reached the end of the tech tree for chemical propulsion bullets and how to be pinpoint dead on balls accurate down to a science, once you've acquired the knowledge and resources to do the same for artillery and triangulation to within millimeters even in adverse weather conditions, once you have the capacity to make and fire hypersonic missiles capable of taking off from the ground, going around the world at LEAST once to its origin point the long way and blowing up or entering orbit and staying up there until a scheduled time or parameters dictate to change trajectory, then, well.. you kind of have every method of long range weapon figured out.
Bows, longbows and crossbows? Yeah. But they're for especially oppressive times. The science and instructions on how to make bows and strings and arrows capable of being fired over 1,000 feet. Given how one doesn't need chemical propellants or potentially brow raising amounts of metals or smithery, they're a lesser science. May even be training wheels for would-be initiates.

Building a cargo spaceship capable of exploring our solar system based on current technology and the knowledge gleaned from our understanding of engineering, science, and chemistry requires us to work within practical and realistic constraints, given that we're not yet in an era of faster-than-light travel. This project would involve a modular design, reliable propulsion systems, life support, cargo handling, and advanced automation or AI. Here’s a conceptual breakdown:
1. Ship Structure
Hull and Frame: A spaceship designed for deep space exploration needs a durable, lightweight frame. Advanced materials like titanium alloys and carbon-fiber composites would be used to ensure structural integrity under the stress of space travel while keeping the mass low. The outer hull would be made with multi-layered insulation to protect against micrometeorites and space radiation.
Dimensions: A cargo space vessel could be roughly 80-100 meters long and 30 meters wide, giving it sufficient space for cargo holds, living quarters, and propulsion systems.
Cost: $500 million (materials, assembly, and insulation).
2. Propulsion Systems
Primary Propulsion: Nuclear Thermal Propulsion (NTP) or Nuclear Electric Propulsion (NEP):
NTP would involve heating hydrogen with a nuclear reactor to achieve high exhaust velocities, providing faster travel times across the solar system. NEP converts nuclear energy into electricity, driving highly efficient ion thrusters. Both systems offer relatively efficient interplanetary travel.
A hybrid solution between NTP and NEP could optimize fuel efficiency for longer trips and maneuverability near celestial bodies.
Cost: $1 billion (development of nuclear propulsion, reactors, and installation).
Fuel: For NTP, hydrogen would be used as a propellant; for NEP, xenon or argon would be the ionized fuel. It would be replenished through in-space refueling depots or by mining water on asteroids and moons (future prospect).
Cost (fuel): $50 million.
3. Power Systems
Nuclear Fission Reactor: A compact fission reactor would power the ship’s life support, propulsion, and onboard systems. Reactors designed by NASA’s Kilopower project would provide consistent energy for long missions.
Backup Solar Arrays: Solar panels, optimized for efficiency beyond Mars’ orbit, would serve as secondary power sources in case of reactor failure.
Cost: $300 million (including reactors, solar panels, and energy storage systems).
4. Cargo Modules
The cargo holds need to be pressurized and temperature-controlled for sensitive materials or scientific samples, while some holds could be left unpressurized for bulk materials like metals, water, or fuel.
Modular Design: The ship should have detachable cargo pods for easy unloading and resupply at different planetary bodies or space stations.
Cost: $200 million (modular design, pressurization systems, automation).
5. Life Support Systems
Water and Oxygen Recycling: Systems like NASA’s Environmental Control and Life Support System (ECLSS) would recycle water, oxygen, and even waste. These systems are key for long-duration missions where resupply may be limited.
CO2 Scrubbers: To remove carbon dioxide from the air, maintaining breathable conditions for the crew.
Artificial Gravity (optional): A rotating section of the ship could generate artificial gravity through centripetal force, improving the crew’s health on longer missions. However, this would increase complexity and cost.
Cost: $200 million (life support systems, with optional artificial gravity setup).
6. AI and Automation
AI-Controlled Systems: AI would manage navigation, propulsion optimization, cargo handling, and even medical diagnostics. Automated drones could be used for ship maintenance and repairs in space.
Navigation: Advanced AI would assist in calculating complex orbital maneuvers, interplanetary transfers, and landings.
Autonomous Cargo Handling: Robotics and AI would ensure that cargo can be efficiently moved between space stations, planets, and the ship.
Cost: $150 million (AI development, robotics, automation).
7. Communication and Sensors
Communication Arrays: High-gain antennas would allow for deep-space communication back to Earth, supplemented by laser communication systems for high-speed data transfers.
Radars and Sensors: For mapping asteroid belts, detecting anomalies, and navigating planets, advanced LIDAR, radar, and spectrometers would be necessary. These sensors would aid in planetary exploration and mining operations.
Cost: $100 million (communication systems, sensors, and diagnostics).
8. Radiation Protection
Water Shielding: Water, which is also used in life support, would double as a radiation shield around the living quarters.
Electromagnetic Shields: Experimental concepts involve creating a small electromagnetic field around the ship to deflect solar and cosmic radiation (early TRL, requires more development).
Cost: $50 million (radiation shielding).
9. Crew Quarters
Living Quarters: Designed for long-duration missions with the capability to house 4-6 crew members comfortably. The quarters would feature radiation protection, artificial lighting cycles to simulate day and night, and recreational facilities to maintain crew morale on multi-year missions.
Medical Bay: An AI-assisted medical bay equipped with robotic surgery and telemedicine would ensure the crew remains healthy.
Cost: $100 million (crew quarters, recreational facilities, medical systems).
10. Landing and Exploration Modules
Surface Exploration Vehicles: For landing on moons or planets like Mars or Europa, a modular lander or rover system would be required. These vehicles would use methane/oxygen engines or electric propulsion to take off and land on various celestial bodies.
Cost: $300 million (lander, rovers, exploration modules).
---
Total Estimated Cost: $2.95 Billion
Additional Considerations:
1. Launch Vehicles: To get the spacecraft into orbit, you would need a heavy-lift rocket like SpaceX’s Starship or NASA’s Space Launch System (SLS). Multiple launches may be required to assemble the ship in orbit.
Cost (launch): $500 million (several launches).
2. In-Space Assembly: The ship would likely be built and assembled in low-Earth orbit (LEO), with components brought up in stages by heavy-lift rockets.
Cost: $200 million (orbital assembly infrastructure and operations).
---
Grand Total: $3.65 Billion
This estimate provides a general cost breakdown for building a cargo spaceship that could explore and transport materials across the solar system. This concept ship is realistic based on near-future technologies, leveraging both nuclear propulsion and automation to ensure efficient exploration and cargo transportation across the solar system.

Good News From Israel
In the 16th July 23 edition of Israel’s good news, the highlights include:
Israeli personally tailored therapies can cure infections and infertility.
Israeli surgeons don’t need electricity to save a life in Ethiopia.
Israeli scientists won awards from France and NASA.
A new European fund is to invest a quarter of a billion dollars in Israeli startups.
An Israeli startup will generate electricity from Taiwan’s choppy seas.
The Israel Premier Tech cycling team won the 9th stage of the Tour de France.
An Israeli NGO is saving the bees – one swarm at a time.
This newsletter edition is entitled "Chai-Tech", merging the term "Hi-Tech" with "Chai" - the Hebrew word for "Living" / "Lives". The reason is that there is so much recent news about Israeli technology to benefit human lives.
Almost all the medical articles involve Israelis using hi-tech to save lives, including breakthroughs in personalized medicine, global vaccines, stroke monitors, digital insoles, brain disease diagnosis, prescription checkers and the innovations of Sheba Medical Center.
Israeli life-saving climate-tech features high in this newsletter with Israel's plans for a 1,000-strong delegation to COP28, the recent climate-tech delegation to the UK, 15 Israeli Climate Awards candidates, France's award to an Israeli hydrogen scientist, and Taiwan implementing Israel's wave energy solution. Israeli hi-tech is also benefiting the environment by using seaweed to generate electricity, turning potato waste foliage into a food source, more vegan substitutes for meat, sustainable farming solutions and ultra-efficient space propulsion.
Other hi-tech programs include multi-million investments into Israeli companies developing 3D printed organs, security for schools, digital health, food-tech and agri-tech solutions. No wonder Israeli hi-tech startups are actively being sought by the US States of Virginia and Maryland.
The photo shows the construction of a solar roof over the soccer pitch of our local school in Netanya, providing shade to the young players, and green electricity for the school and the grid. Another "high"-tech solution making life better for the next generation. Am Yisrael Chai!

IS THE MOON RUSTING??
Blog#341
Wednesday, October 18th, 2023
Welcome back,
While our Moon is airless, research indicates the presence of hematite, a form of rust that normally requires oxygen and water. That has scientists puzzled.
Mars has long been known for its rust. Iron on its surface, combined with water and oxygen from the ancient past, give the Red Planet its hue. But scientists were recently surprised to find evidence that our airless Moon has rust on it as well.
A new paper in Science Advances reviews data from the Indian Space Research Organization's Chandrayaan-1 orbiter, which discovered water ice and mapped out a variety of minerals while surveying the Moon's surface in 2008. Lead author Shuai Li of the University of Hawaii has studied that water extensively in data from Chandrayaan-1's Moon Mineralogy Mapper instrument, or M3, which was built by NASA's Jet Propulsion Laboratory in Southern California. Water interacts with rock to produce a diversity of minerals, and M3 detected spectra - or light reflected off surfaces - that revealed the Moon's poles had a very different composition than the rest of it.
Intrigued, Li homed in on these polar spectra. While the Moon's surface is littered with iron-rich rocks, he nevertheless was surprised to find a close match with the spectral signature of hematite. The mineral is a form of iron oxide, or rust, produced when iron is exposed to oxygen and water. But the Moon isn't supposed to have oxygen or liquid water, so how can it be rusting?
The mystery starts with the solar wind, a stream of charged particles that flows out from the Sun, bombarding Earth and the Moon with hydrogen. Hydrogen makes it harder for hematite to form. It's what is known as a reducer, meaning it adds electrons to the materials it interacts with. That's the opposite of what is needed to make hematite: For iron to rust, it requires an oxidizer, which removes electrons. And while the Earth has a magnetic field shielding it from this hydrogen, the Moon does not.
"It's very puzzling," Li said. "The Moon is a terrible environment for hematite to form in." So he turned to JPL scientists Abigail Fraeman and Vivian Sun to help poke at M3's data and confirm his discovery of hematite.
"At first, I totally didn't believe it. It shouldn't exist based on the conditions present on the Moon," Fraeman said. "But since we discovered water on the Moon, people have been speculating that there could be a greater variety of minerals than we realize if that water had reacted with rocks."
After taking a close look, Fraeman and Sun became convinced M3's data does indeed indicate the presence of hematite at the lunar poles. "In the end, the spectra were convincingly hematite-bearing, and there needed to be an explanation for why it's on the Moon," Sun said.
Their paper offers a three-pronged model to explain how rust might form in such an environment. For starters, while the Moon lacks an atmosphere, it is in fact home to trace amounts of oxygen.
The source of that oxygen: our planet. Earth's magnetic field trails behind the planet like a windsock. In 2007, Japan's Kaguya orbiter discovered that oxygen from Earth's upper atmosphere can hitch a ride on this trailing magnetotail, as it's officially known, traveling the 239,000 miles (385,00 kilometers) to the Moon.
That discovery fits with data from M3, which found more hematite on the Moon's Earth-facing near side than on its far side. "This suggested that Earth's oxygen could be driving the formation of hematite," Li said. The Moon has been inching away from Earth for billions of years, so it's also possible that more oxygen hopped across this rift when the two were closer in the ancient past.
Then there's the matter of all that hydrogen being delivered by the solar wind. As a reducer, hydrogen should prevent oxidation from occurring. But Earth's magnetotail has a mediating effect. Besides ferrying oxygen to the Moon from our home planet, it also blocks over 99% of the solar wind during certain periods of the Moon's orbit (specifically, whenever it's in the full Moon phase). That opens occasional windows during the lunar cycle when rust can form.
