The Artemis I Mission: To the Moon and Back

The Artemis I mission was the first integrated test of the Orion spacecraft, the Space Launch System (SLS) rocket, and Exploration Ground Systems at NASA’s Kennedy Space Center in Florida. We’ll use these deep space exploration systems on future Artemis missions to send astronauts to the Moon and prepare for our next giant leap: sending the first humans to Mars.

Take a visual journey through the mission, starting from launch, to lunar orbit, to splashdown.

Liftoff

The SLS rocket carrying the Orion spacecraft launched on Nov. 16, 2022, from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. The world’s most powerful rocket performed with precision, meeting or exceeding all expectations during its debut launch on Artemis I.

"This is Your Moment"

Following the successful launch of Artemis I, Launch Director Charlie Blackwell-Thompson congratulates the launch team.

“The harder the climb, the better the view,” she said. “We showed the space coast tonight what a beautiful view it is.”

That's Us

On Orion’s first day of flight, a camera on the tip of one of Orion’s solar arrays captured this image of Earth.

Inside Orion

On the third day of the mission, Artemis I engineers activated the Callisto payload, a technology demonstration developed by Lockheed Martin, Amazon, and Cisco that tested a digital voice assistant and video conferencing capabilities in a deep space environment. In the image, Commander Moonikin Campos occupies the commander’s seat inside the spacecraft. The Moonikin is wearing an Orion Crew Survival System suit, the same spacesuit that Artemis astronauts will use during launch, entry, and other dynamic phases of their missions. Campos is also equipped with sensors that recorded acceleration and vibration data throughout the mission that will help NASA protect astronauts during Artemis II. The Moonikin was one of three “passengers” that flew aboard Orion. Two female-bodied model human torsos, called phantoms, were aboard. Zohar and Helga, named by the Israel Space Agency (ISA) and the German Aerospace Center (DLR) respectively, supported the Matroshka AstroRad Radiation Experiment (MARE), an experiment to provide data on radiation levels during lunar missions. Snoopy, wearing a mock orange spacesuit, also can be seen floating in the background. The character served as the zero-gravity indicator during the mission, providing a visual signifier that Orion is in space.

Far Side of the Moon

A portion of the far side of the Moon looms large in this image taken by a camera on the tip of one of Orion’s solar arrays on the sixth day of the mission.

First Close Approach

The Orion spacecraft captured some of the closest photos of the Moon from a spacecraft built for humans since the Apollo era — about 80 miles (128 km) above the lunar surface. This photo was taken using Orion’s optical navigational system, which captures black-and-white images of the Earth and Moon in different phases and distances.

Distant Retrograde Orbit

Orion entered a distant retrograde orbit around the Moon almost two weeks into the mission. The orbit is “distant” in the sense that it’s at a high altitude approximately 50,000 miles (80,467 km) from the surface of the Moon. Orion broke the record for farthest distance of a spacecraft designed to carry humans to deep space and safely return them to Earth, reaching a maximum distance of 268,563 miles (432,210 km).

Second Close Approach

On the 20th day of the mission, the spacecraft made its second and final close approach to the Moon flying 79.2 miles (127.5 km) above the lunar surface to harness the Moon’s gravity and accelerate for the journey back to Earth.

Cameras mounted on the crew module of the Orion spacecraft captured these views of the Moon’s surface before its return powered flyby burn.

Heading Home

After passing behind the far side of the Moon on Flight Day 20, Orion powered a flyby burn that lasted approximately 3 minutes and 27 seconds to head home. Shortly after the burn was complete, the Orion spacecraft captured these views of the Moon and Earth, which appears as a distant crescent.

Parachutes Deployed

Prior to entering the Earth’s atmosphere, Orion’s crew module separated from its service module, which is the propulsive powerhouse provided by ESA (European Space Agency). During re-entry, Orion endured temperatures about half as hot as the surface of the Sun at about 5,000 degrees Fahrenheit (2,760 degrees Celsius). Within about 20 minutes, Orion slowed from nearly 25,000 mph (40,236 kph) to about 20 mph (32 kph) for its parachute-assisted splashdown.

Splashdown

On Dec. 11, the Orion spacecraft splashed down in the Pacific Ocean off the coast of California after traveling 1.4 million miles (2.3 million km) over a total of 25.5 days in space. Teams are in the process of returning Orion to Kennedy Space Center in Florida. Once at Kennedy, teams will open the hatch and unload several payloads, including Commander Moonikin Campos, the space biology experiments, Snoopy, and the official flight kit. Next, the capsule and its heat shield will undergo testing and analysis over the course of several months.

houston, we have a problem

When he first met Sokka, he wanted to smack him for the arrogance that seemed to emanate from him. Zuko won’t say his confidence wasn’t earned; Sokka and a second-year tech, Teo, are responsible for the development of NASA’s anti-gravity technology (accomplished while still in graduate school). He’d been streamlined through the interview process, aced his space tests with flying colors, and had the added bonus of impressing Piandao enough within a week of working there that the man had hand-written him a recommendation letter when it came time to choose candidates for TUI-84’s mission to explore plant sustainability in different atmospheric conditions. According to Aunt Wu, Director Jeong Jeong had been so shocked at Piandao’s interference that he hadn’t even bothered considering other technicians. He was one of the youngest first-year candidates NASA had ever considered for a space mission to actually get the job. - Sokka is the youngest space engineer to be sent to outer space. Zuko is the ground control member assigned to track him. Falling in love wasn't part of the mission, but it happened anyway.

Nanowrimo made a half-assed, desperate ""apology"" post

Full text, for when they inevitably try to edit it; as of right now it's August 6th, 2024, around 5:30pm est.

A Note to Our Community About our Comments on AI – September 2024 To the NaNoWriMo Community: In early August, debates about AI on our social media channels became vitriolic. It was clear that the intimidation and harassment we witnessed were causing harm within our community of writers. The FAQs we crafted last week were written to curtail those behaviors. We wanted to send a clear signal that NaNoWriMo spaces would not be used to bully or delegitimize other writers. This was consistent with our May 2024 statement, which named a lack of civility in NaNoWriMo spaces as a longstanding concern. Taking a position of neutrality was not an abandonment of writers’ legitimate concerns about AI. It was an acknowledgment that NaNoWriMo can’t maintain a civil, inclusive community if we allow selective intolerance. We absolutely believe that AI must be discussed and that its ethical use must be advocated-for. What we don’t believe is that NaNoWriMo belongs at the forefront of that conversation. That debate should continue to thrive within the greater writing community as technologies continue to evolve. We apologize that our original message was unclear and seemingly random. Our note on ableism and classism was rooted in the desire to point out that, for people in certain circumstances, some forms of AI can be life-changing. We certainly don’t believe those with concerns about AI to be classist or ableist. Not being more careful about our wording was a bad decision on our part. Our Mission is about providing encouragement to writers and cheering them on as they progress toward their goals. That remains our primary focus. In the future, we will be more transparent about the issues that we are trying to address with any messaging we provide. Finally, we recognize that some members of our community have other questions and concerns that go beyond general context for our comments. We don’t think we can address all of these in a single communication. Additional context here is that we are a very small team (including our Interim Executive Director, who is a volunteer). We want to take the time to read through your letters with the care, attention, and concern they deserve. Please expect more in the coming weeks.  In partnership, The NaNoWriMo Team

I sincerely hope their other sponsors bail ship and leave them to flounder at this point lmao. There is no going back from "if you criticize generative AI you're just ableist classist and racist".

They've also once again edited their "What Is Nanowrimo's Stance on AI?" post:

New text, in full; looks like it was updated sometime late yesterday or early today (August 6th 2024):

What is NaNoWriMo's position on Artificial Intelligence (AI)? 13 hours ago -Updated Not yet followed by anyone

NaNoWriMo neither explicitly supports nor condemns any approach to writing, including the use of tools that  leverage AI. We recognize that harm has been done to the writing and creative communities at the hands of bad actors in the generative AI space, and that the ethical questions and risks posed by some aspects of this technology are real. The fact that AI is a large, complex technology category (which encompasses both non-generative and generative AI, applied in a range of ways to a range of uses) contributes to our belief that AI is simply too big and too varied to categorically support or condemn. NaNoWriMo's mission is to "provide the structure, community, and encouragement to help people use their voices, achieve creative goals, and build new worlds—on and off the page." We fulfill our mission by supporting the humans doing the writing. Please see this related post that speaks to our overall position on nondiscrimination with respect to approaches to creativity, writer's resources, and personal choice.  We made mistakes in our initial expression of this position. We speak to those mistakes in this letter to our community, and we've simplified the language on this page to reflect our core position. 

If you're wondering why Nano's posting all these non-apologies, its because they started this debacle with seven huge sponsors.

Over the course of the last three days, they've gone down to four.

They have literally lost about half their sponsors because of their support of generative ai.

And, as you can see in the "apologies" above, they're still defending their AI stance, by now claiming that their stance is because they were defending poor, hapless AI users from a horde of harassment and bullying from all sides, and they're not a platform that condones bullying! totally! (sarcasm).

Have you SEEN the original moon landing feed, especially the scary bit near the end?

Now stay with me. I grew up hearing about these few minutes from my parents (in fact I took the TV they watched it on to grad school; DS9 and Babylon5 worked well in b&w).

This is even crazier than it looks like.

My parents were both scientists, my grandmother a planetarium director, and my dad was just about to land his job at a rocket company that built 95 small rockets that were part of the UpGoer Saturn V. (Yeah. Just the small ones. Saturn V was a BEAST.)

So my parents had a fair idea how dangerous this was, how Neil going manual was a bad sign, and just how close he was to running empty and crashing. They knew the problem that every ounce of fuel you carry requires even more fuel to lift off, so the Eagle was built light, carrying no excess weight even in fuel (it had to lift off the Moon with no rocket, after all).

But they didn't learn until years later just how jury-rigged and bespoke Apollo technology was. Every vehicle and part was designed like a Mythbusters build: extremely customized for the procedures it had to accomplish, using parts and even technology invented for specific mission tasks.

rope memory, predecessor to modern silicon chips: 1s and 0s woven by women (of course) at a Massachusetts textile plant

At the time, computers were the size of rooms and very touchy. Apollo's computer memory was core rope memory, never used before or since, to save space. The read/write guidance computer, too, was woven: physical media could better survive the rigors of space travel. (I suspect even my parents don't know it also used some of the very first integrated circuits, soldered by hand under a microscope by Navajo women).

Spacesuits were (and still are) designed and hand-stitched by Playtex bramakers. The lunar rovers' wheels were titanium meshes woven with piano wire to let dust through, and even had a clever navigation system despite no GPS or magnetic north.

They couldn't test these rigs with computer modeling. They didn't know for sure what the moon's surface would be like, apart from basic parameters like low gravity and near vacuum and a temperature ranging from 250°F in the sun to -250° in the shade. And it was nearly impossible to test for or practice in those conditions on Earth.

And then there were the unknowns. A massive solar flare between Apollo 16 and 17 might have killed or sickened them too much to operate their ship.

While the spacesuit and to some extent the rover design carried on, a lot of these hacks were so unusual that they might as well be alien tech. (I'm sorry woven technology fell out of vogue for several decades.) That goes some way towards explaining why humans haven't left Earth orbit since I was two.

The other problem, of course, is expense. Tech for human space exploration requires as much R&D and testing as fighter planes, which have developed through a century of multiple countries' military budgets. Human space programs are lucky to last two presidents; the next president usually doesn't think giving glory to his predecessor is a good use of money.

So for 40 years, NASA has mostly worked with other countries on human spaceflight or built robot explorers that can be launched in 3-4 years before Congress or the president can axe the program. They're less likely to shut down a mission when 99.99% of the money's been spent, and all that's left to do is download data and uplink occasional instructions.

TL:DR; Congress and the White House keep flashing the equivalent of that computer error message, every time NASA gets ready to send humans into space again. Overload. Abort mission.

Unless, you know, American citizens start saying Go. Go. Go. Go. We have some pretty important priorities down here on Earth (which Amazon and Disney and oil companies should be footing the bill for, though they try not to), but I bet the military can cough up the cost of a few fighter jets.

Watch the First Trailer for Michelle Yeoh’s STAR TREK: SECTION 31

The big Star Trek Universe panel wrapped up today with a first look at the upcoming Michelle Yeoh-lead Star Trek: Section 31 movie — more than five years after the idea of a Emperor Georgiou spin-off project was first announced.   Section 31 director Olatunde Osunsanmi was joined on the Hall H stage by Trek franchise boss Alex Kurtzman and cast members Omari Hardwick, Sam Richardson and Kacey Rohl who spoke about the upcoming film set to hit Paramount+ in early 2025.   The teaser was introduced by the film’s star, Academy Award winner Michelle Yeoh, by way of a special video message for the assembled SDCC audience.

The teaser gives viewers a taste of one of the Section 31 team’s missions — an action-filled visit to some kind of space nightclub, with a spaceship chase sequence — along with a hint of some of the flashbacks to Emperor Georgiou’s initial rise to power, growing up in the Mirror Universe.

Some of the cast featured in the teaser includes Kacey Rohl as Rachel Garrett (eventual captain of the Enterprise-C), Omari Hardwick, Sam Richardson (playing a Chameloid), Sven Ruygrok as a Vulcan, Humberly Gonzalez as a Deltan, and Robert Kazinsky as some sort of technologically-enhanced humanoid — perhaps an ex-Borg?

Also joining the cast is actor Miku Martineau, who portrays the younger version of Philippa Georgiou.

What this teaser does not give us is a taste of when the movie is expected to be set — the early 24th century, in the years after Star Trek VI: The Undiscovered Country and several decades before the events of Star Trek: The Next Generation. Aside from Garrett’s mention of Starfleet and a few familiar Trek aliens, there’s little connection to the “Lost Era” time period we’ve been expecting since Kacey Rohl’s character was announced back in March.

More news and footage from the film will roll out in the next several months, so we’re likely to get a wider look at the world of Star Trek: Section 31 before its 2025 debut.

Star Trek: Section 31 is in post-production now.

Cancelled Missions: NASA's October 1977 Space Shuttle Flight Itinerary

"Soon after President Richard Nixon gave his blessing to the Space Shuttle Program on January 5, 1972, NASA scheduled its first orbital flight for 1977, then for March 1978. By early 1975, the date had slipped to March 1979. Funding shortfalls were to blame, as were the daunting engineering challenges of developing the world's first reusable orbital spaceship based on 1970s technology. The schedule slip was actually worse than NASA let on: as early as January 32, 1975, an internal NASA document (marked 'sensitive') gave a '90% probability date' for the first Shuttle launch of December 1979.

In October 1977, Chester Lee, director of Space Transportation System (STS) Operations at NASA Headquarters, distributed the first edition of the STS Flight Assignment Baseline, a launch schedule and payload manifest for the first 16 operational Shuttle missions. The document was in keeping with NASA's stated philosophy that reusable Shuttle Orbiters would fly on-time and often, like a fleet of cargo airplanes. The STS Utilization and Operations Office at NASA's Johnson Space Center (JSC) in Houston had prepared the document, which was meant to be revised quarterly as new customers chose the Space Shuttle as their cheap and reliable ride to space.

The JSC planners assumed that six Orbital Flight Test (OFT) missions would precede the first operational Shuttle flight. The OFT flights would see two-man crews (Commander and Pilot) put Orbiter Vehicle 102 (OV-102) through its paces in low-Earth orbit. The planners did not include the OFT schedule in their document, but the May 30, 1980 launch date for their first operational Shuttle mission suggests that they based their flight schedule on the March 1979 first OFT launch date.

Thirteen of the 16 operational flights would use OV-102 and three would use OV-101. NASA would christen OV-102 Columbia in February 1979, shortly before it rolled out of the Rockwell International plant in Palmdale, California.

As for OV-101, its name was changed from Constitution to Enterprise in mid-1976 at the insistence of Star Trek fans. Enterprise flew in Approach and Landing Test (ALT) flights at Edwards Air Force Base in California beginning on February 15, 1977. ALT flights, which saw the Orbiter carried by and dropped from a modified 747, ended soon after the NASA JSC planners released their document.

The first operational Space Shuttle mission, Flight 7 (May 30 - June 3, 1980), would see Columbia climb to a 225-nautical-mile (n-mi) orbit inclined 28.5° relative to Earth's equator (unless otherwise stated, all orbits are inclined at 28.5°, the latitude of Kennedy Space Center in Florida). The delta-winged Orbiter would carry a three-person crew in its two-deck crew compartment and the bus-sized Long Duration Exposure Facility (LDEF) in its 15-foot-wide, 60-foot-long payload bay.

Columbia would also carry a 'payload of opportunity' - that is, an unspecified payload. The presence of a payload of opportunity meant that the flight had available excess payload weight capacity. Payload mass up would total 27,925 pounds. Payload mass down after the Remote Manipulator System (RMS) arm hoisted LDEF out of Columbia's payload bay and released it into orbit would total 9080 pounds.

A page from the STS Flight Assignment Baseline document of October 1977 shows payloads and other features of the first five operational Space Shuttle missions plus Flight 12/Flight 12 Alternate

During Flight 8 (July 1-3, 1980), Columbia would orbit 160 n mi above the Earth. Three astronauts would release two satellites and their solid-propellant rocket stages: Tracking and Data Relay Satellite-A (TDRS-A) with a two-stage Interim Upper Stage (IUS) and the Satellite Business Systems-A (SBS-A) commercial communications satellite on a Spinning Solid Upper Stage-Delta-class (SSUS-D).

Prior to release, the crew would spin the SBS-A satellite about its long axis on a turntable to create gyroscopic stability and raise TDRS-A on a tilt-table. After release, their respective solid-propellant stages would propel them to their assigned slots in geostationary orbit (GEO), 19,323 n mi above the equator. Payload mass up would total 51,243 pounds; mass down, 8912 pounds, most of which would comprise reusable restraint and deployment hardware for the satellites.

The TDRS system, which would include three operational satellites and an orbiting spare, was meant to trim costs and improve communications coverage by replacing most of the ground-based Manned Space Flight Network (MSFN). Previous U.S. piloted missions had relied on MSFN ground stations to relay communications to and from the Mission Control Center (MCC) in Houston. Because spacecraft in low-Earth orbit could remain in range of a given ground station for only a few minutes at a time, astronauts were frequently out of contact with the MCC.

On Flight 9 (August 1-6, 1980), Columbia would climb to a 160-n-mi orbit. Three astronauts would deploy GOES-D, a National Oceanic and Atmospheric Administration (NOAA) weather satellite, and Anik-C/1, a Canadian communications satellite. Before release, the crew would raise the NOAA satellite and its SSUS-Atlas-class (SSUS-A) rocket stage on the tilt-table and spin up the Anik-C/1-SSUS-D combination on the turntable. In addition to the two named satellites, NASA JSC planners reckoned that Columbia could carry a 14,000-pound payload of opportunity. Payload mass up would total 36,017 pounds; mass down, 21,116 pounds.

Following Flight 9, NASA would withdraw Columbia from service for 12 weeks to permit conversion from OFT configuration to operational configuration. The JSC planners explained that the conversion would be deferred until after Flight 9 to ensure an on-time first operational flight and to save time by combining it with Columbia's preparations for the first Spacelab mission on Flight 11. The switch from OFT to operational configuration would entail removal of Development Flight Instrumentation (sensors for monitoring Orbiter systems and performance); replacement of Commander and Pilot ejection seats on the crew compartment upper deck (the flight deck) with fixed seats; power system upgrades; and installation of an airlock on the crew compartment lower deck (the mid-deck).

Flight 10 (November 14-16, 1980) would be a near-copy of Flight 8. A three-person Columbia crew would deploy TDRS-B/IUS and SBS-B/SSUS-D into a 160-n-mi-high orbit. The rocket stages would then boost the satellites to GEO. Cargo mass up would total 53,744 pounds; mass down, 11,443 pounds.

Flight 11 (December 18-25, 1980) would see the orbital debut of Spacelab. Columbia would orbit Earth 160 n mi high at 57° of inclination. NASA and the multinational European Space Research Organization (ESRO) agreed in August 1973 that Europe should develop and manufacture Spacelab pressurized modules and unpressurized pallets for use in the Space Shuttle Program. Initially dubbed the 'sortie lab,' Spacelab would operate only in the Orbiter payload bay; it was not intended as an independent space station, though many hoped that it would help to demonstrate that an Earth-orbiting station could be useful.

ESRO merged with the European Launcher Development Organization in 1975 to form the European Space Agency (ESA). Columbia's five-person crew for Flight 11 would probably include scientists and at least one astronaut from an ESA member country.

Flight 12 (January 30 - February 1, 1981), a near-copy of Flights 8 and 10, would see Columbia's three-person crew deploy TDRS-C/IUS and Anik-C/2/SSUS-D into 160-n-mi-high orbit. Payload mass up would total 53,744 pounds; mass down, 11,443 pounds.

JSC planners inserted an optional 'Flight 12 Alternate' (January 30 - February 4, 1981) into their schedule which, if flown, would replace Flight 12. Columbia would orbit 160 n mi above the Earth. Its three-person crew would deploy Anik-C/2 on a SSUS-D stage. The mission's main purpose, however, would be to create a backup launch opportunity for an Intelsat V-class satellite already scheduled for launch on a U.S. Atlas-Centaur or European Ariane I rocket. An SSUS-A stage would boost the Intelsat V from Shuttle orbit to GEO.

NASA JSC assumed that, besides the satellites, stages, and their support hardware, Columbia would for Flight 12 Alternate tote an attached payload of opportunity that would need to operate in space for five days to provide useful data (hence the mission's planned duration). Payload mass up would total 37,067 pounds; mass down, 17,347 pounds.

Space Shuttle Flights 13 through 18 would include the first orbital mission of the OV-101 Enterprise (Flight 17), during which astronauts would retrieve the LDEF payload deployed during Flight 7.

Flight 13 (March 3-8, 1981) would see three astronauts on board Columbia release NOAA's GOES-E satellite attached to an SSUS-D stage into a 160-n-mi-high orbit. OV-102 would have room for two payloads of opportunity: one attached at the front of the payload bay and one deployed from a turntable aft of the GOES-E/SSUS-D combination. Payload mass up would total 38,549 pounds; mass down, 23,647 pounds.

Flight 14 would last 12 days, making it the longest described in the STS Flight Assignment Baseline document. Scheduled for launch on April 7, 1981, it would carry a 'train' of four unpressurized Spacelab experiment pallets and an 'Igloo,' a small pressurized compartment for pallet support equipment. The Igloo, though pressurized, would not be accessible to the five-person crew. OV-102 would orbit 225 n mi high at an inclination of 57°. Mass up would total 31,833 pounds; mass down, 28,450 pounds.

Flight 15 (May 13-15, 1981) would be a near-copy of Flights 8, 10, and 12. OV-102 would transport to orbit a payload totaling 53,744 pounds; payload mass down would total 11,443 pounds. The JSC planners noted the possibility that none of the potential payloads for Flight 15 — TDRS-D and SBS-C or Anik-C/3 — would need to be launched as early as May 1981. TDRS-D was meant as an orbiting spare; if the first three TDRS operated as planned, its launch could be postponed. Likewise, SBS-C and Anik-C/3 were each a backup for the previously launched satellites in their series.

Flight 16 (June 16-23, 1981) would be a five-person Spacelab pressurized module flight aboard OV-102 in 160-n-mi-high orbit. Payloads of opportunity totaling about 18,000 pounds might accompany the Spacelab module; for planning purposes, a satellite and SSUS-D on a turntable behind the module was assumed. Payload mass up would total 35,676 pounds; mass down, 27,995 pounds.

Flight 17, scheduled for July 16-20, 1981, would see the space debut of Enterprise and the retrieval of the LDEF released during Flight 7. OV-101 would climb to a roughly 200-n-mi-high orbit (LDEF's altitude after 13.5 months of orbital decay would determine the mission's precise altitude).

Before rendezvous with LDEF, Flight 17's three-man crew would release an Intelsat V/SSUS-A and a satellite payload of opportunity. After the satellites were sent on their way, the astronauts would pilot Enterprise to a rendezvous with LDEF, snare it with the RMS, and secure it in the payload bay. Mass up would total 26,564 pounds; mass down, 26,369 pounds.

For Flight 18 (July 29-August 5, 1981), Columbia would carry to a 160-n-mi-high orbit a Spacelab pallet dedicated to materials processing in the vacuum and microgravity of space. The three-person flight might also include the first acknowledged Department of Defense (DOD) payload of the Space Shuttle Program, a U.S. Air Force pallet designated STP-P80-1. JSC called the payload 'Planned' rather than 'Firm' and noted somewhat cryptically that it was the Teal Ruby experiment 'accommodated from OFT [Orbital Flight Test].'

The presence of the Earth-directed Teal Ruby sensor payload would account for Flight 18's planned 57° orbital inclination, which would take it over most of Earth's densely populated areas. Payload mass up might total 32,548 pounds; mass down, 23,827 pounds.

Space Shuttle Flights 20 through 23 would include the first mission to make use of an OMS kit to increase its orbital altitude (Flight 21), the first European Space Agency-sponsored Spacelab mission (Flight 22), and the launch of the Jupiter Orbiter and Probe spacecraft (Flight 23)

Flight 19 (September 2-9, 1981) would see five Spacelab experiment pallets fill Columbia's payload bay. Five astronauts would operate the experiments, which would emphasize physics and astronomy. The Orbiter would circle Earth in a 216-n-mi-high orbit. Payload mass up would total 29,214 pounds; mass down, 27,522 pounds.

Flight 20 (September 30-October 6, 1981), the second Enterprise mission, would see five astronauts conduct life science and astronomy experiments in a 216-n-mi-high orbit using a Spacelab pressurized module and an unpressurized pallet. JSC planners acknowledged that the mission's down payload mass (34,248 pounds) might be 'excessive,' but noted that their estimate was 'based on preliminary payload data.' Mass up would total 37,065 pounds.

On Flight 21, scheduled for launch on October 14, 1981, Columbia would carry the first Orbital Maneuvering System (OMS) Kit at the aft end of its payload bay. The OMS Kit would carry enough supplemental propellants for the Orbiter's twin rear-mounted OMS engines to perform a velocity change of 500 feet per second. This would enable OV-102 to rendezvous with and retrieve the Solar Maximum Mission (SMM) satellite in a 300-n-mi-high orbit.

Three astronauts would fly the five-day mission, which would attain the highest orbital altitude of any flight in the STS Flight Assignment Baseline document. JSC planners noted that the Multi-mission Modular Spacecraft (MMS) support hardware meant to carry SMM back to Earth could also transport an MMS-type satellite into orbit. Payload mass up would total 37,145 pounds; mass down, 23,433 pounds.

On Flight 22 (November 25 - December 2, 1981), Enterprise might carry an ESA-sponsored Spacelab mission with a five-person crew, a pressurized lab module, and a pallet to a 155-to-177-n-mi orbit inclined at 57°. Payload mass up might total 34,031 pounds; mass down, 32,339 pounds.

During Flight 23 (January 5-6, 1982), the last described in the STS Flight Assignment Baseline document, three astronauts would deploy into a 150-to-160-n-mi-high orbit the Jupiter Orbiter and Probe (JOP) spacecraft on a stack of three IUSs. President Jimmy Carter had requested new-start funds for JOP in his Fiscal Year 1978 NASA budget, which had taken effect on October 1, 1977. Because JOP was so new when they prepared their document, JSC planners declined to estimate up/down payload masses.

Flight 23 formed an anchor point for the Shuttle schedule because JOP had a launch window dictated by the movements of the planets. If the automated explorer did not leave for Jupiter between January 2 and 12, 1982, it would mean a 13-month delay while Earth and Jupiter moved into position for another launch attempt.

Almost nothing in the October 1977 STS Flight Assignment Baseline document occurred as planned. It was not even updated quarterly; no update had been issued as of mid-November 1978, by which time the target launch dates for the first Space Shuttle orbital mission and the first operational Shuttle flight had slipped officially to September 28, 1979 and February 27, 1981, respectively.

The Space Shuttle Orbiter Columbia lifts off at the start of STS-1.

The first Shuttle flight, designated STS-1, did not in fact lift off until April 12, 1981. As in the STS Flight Assignment Baseline document, OV-102 Columbia performed the OFT missions; OFT concluded, however, after only four flights. After the seven-day STS-4 mission (June 27 - July 4, 1982), President Ronald Reagan declared the Shuttle operational.

The first operational flight, also using Columbia, was STS-5 (November 11-16, 1982). The mission launched SBS-3 and Anik-C/3; because of Shuttle delays, the other SBS and Anik-C satellites planned for Shuttle launch had already reached space atop expendable rockets.

To the chagrin of many Star Trek fans, Enterprise never reached space. NASA decided that it would be less costly to convert Structural Test Article-099 into a flight-worthy Orbiter than to refit Enterprise for spaceflight after the ALT series. OV-099, christened Challenger, first reached space on mission STS-6 (April 4-9, 1983), which saw deployment of the first TDRS satellite.

NASA put OV-101 Enterprise to work in a variety of tests and rehearsals (such as the 'fit check' shown in the image above), but did not convert it into a spaceflight-worthy Orbiter.

The voluminous Spacelab pressurized module first reached orbit on board Columbia on mission STS-9 (November 28- December 8,1983). The 10-day Spacelab 1 mission included ESA researcher Ulf Merbold and NASA scientist-astronauts Owen Garriott and Robert Parker. Garriott, selected to be an astronaut in 1965, had flown for 59 days on board the Skylab space station in 1973. Parker had been selected in 1967, but STS-9 was his first spaceflight.

The 21,500-pound LDEF reached Earth orbit on board Challenger on STS-41C, the 11th Space Shuttle mission (April 6-13, 1984). During the same mission, astronauts captured, repaired, and released the SMM satellite, which had reached orbit on 14 February 1980 and malfunctioned in January 1981. Challenger reached SMM without an OMS kit; in fact, no OMS kit ever reached space.

STS Flight Assignment Baseline document assumed that 22 Shuttle flights (six OFT and 16 operational) would occur before January 1982. In fact, the 22nd Shuttle flight did not begin until October 1985, when Challenger carried eight astronauts and the West German Spacelab D1 into space (STS-61A, October 30 - November 6, 1985). Three months later (28 January 1986), Challenger was destroyed at the start of STS-51L, the Shuttle Program's 25th mission.

In addition to seven astronauts — NASA's first in-flight fatalities — Challenger took with it TDRS-B, NASA's second TDRS satellite. The Shuttle would not fly again until September 1988 (STS-26, September 29 - October 3, 1988). On that mission, OV-103 Discovery deployed TDRS-C. The TDRS system would not include the three satellites necessary for global coverage until TDRS-D reached orbit on board Discovery on mission STS-29 (13-18 March 1989).

Following the Challenger accident, NASA abandoned — though not without some resistance — the pretense that it operated a fleet of cargo planes. The space agency had at one time aimed for 60 Shuttle flights per year; between 1988 and 2003, the Shuttle Program managed about six per year. The most flights the Shuttle fleet accomplished in a year was nine in 1985.

Shuttle delays meant that JOP, renamed Galileo, missed its early January 1982 launch window. It was eventually rescheduled for May 1986, but the Challenger accident intervened. Galileo finally left Earth orbit on 18 October 1989 following deployment from OV-104 Atlantis during STS-34 (October 18-23, 1989).

Between the time JOP/Galileo received its first funding and the Challenger explosion, NASA, the White House, and Congress had sparred over how the Jupiter spacecraft would depart Earth orbit. Eventually, they settled on the powerful liquid-propellant Centaur-G' rocket stage.

Citing new concern for safety following Challenger, NASA canceled Centaur G'. Galileo had to rely on the less-powerful IUS, which meant that it could not travel directly to Jupiter; it had instead to perform gravity-assist flybys of Venus and Earth to reach its exploration target. Galileo did not reach the Jupiter system until December 1995.

LDEF had been scheduled for retrieval in March 1985, less than a year after deployment, but flight delays and the Challenger accident postponed its return to Earth by nearly six years. On mission STS-32 (January 9-20, 1990), astronauts on board Columbia retrieved LDEF, the orbit of which had decayed to 178 n mi. LDEF remains the largest object ever retrieved in space and returned to Earth.

During reentry at the end of mission STS-107 (16 January-1 February 2003), Columbia broke apart over northeast Texas, killing its international crew of seven astronauts. This precipitated cancellation of the Space Shuttle Program by President George W. Bush, who announced his decision on 14 January 2004.

The end of the Space Shuttle Program was originally scheduled for 2010, immediately following the planned completion of the International Space Station. In the event, STS-135, the final Space Shuttle mission, took place four years ago (July 2011), three months after the 30th anniversary of STS-1. The Orbiter Atlantis lifted off on 8 July with a four-person crew — the smallest since STS-6. It docked with the International Space Station to deliver supplies and spares and landed in Florida 13 days later."

NASA's mini BurstCube mission detects mega blast

The shoebox-sized BurstCube satellite has observed its first gamma-ray burst, the most powerful kind of explosion in the universe, according to a recent analysis of observations collected over the last several months.

“We’re excited to collect science data,” said Sean Semper, BurstCube’s lead engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s an important milestone for the team and for the many early career engineers and scientists that have been part of the mission.”

The event, called GRB 240629A, occurred on June 29 in the southern constellation Microscopium. The team announced the discovery in a GCN (General Coordinates Network) circular on August 29.

BurstCube deployed into orbit April 18 from the International Space Station, following a March 21 launch.

The mission was designed to detect, locate, and study short gamma-ray bursts, brief flashes of high-energy light created when superdense objects like neutron stars collide. These collisions also produce heavy elements like gold and iodine, an essential ingredient for life as we know it. 

BurstCube is the first CubeSat to use NASA’s TDRS (Tracking and Data Relay Satellite) system, a constellation of specialized communications spacecraft. Data relayed by TDRS (pronounced “tee-driss”) help coordinate rapid follow-up measurements by other observatories in space and on the ground through NASA’s GCN.

BurstCube also regularly beams data back to Earth using the Direct to Earth system — both it and TDRS are part of NASA’s Near Space Network.

After BurstCube deployed from the space station, the team discovered that one of the two solar panels failed to fully extend. It obscures the view of the mission’s star tracker, which hinders orienting the spacecraft in a way that minimizes drag. The team originally hoped to operate BurstCube for 12-18 months, but now estimates the increased drag will cause the satellite to re-enter the atmosphere in September. 

“I’m proud of how the team responded to the situation and is making the best use of the time we have in orbit,” said Jeremy Perkins, BurstCube’s principal investigator at Goddard. “Small missions like BurstCube not only provide an opportunity to do great science and test new technologies, like our mission’s gamma-ray detector, but also important learning opportunities for the up-and-coming members of the astrophysics community.”

BurstCube is led by Goddard. It’s funded by the Science Mission Directorate’s Astrophysics Division at NASA Headquarters. The BurstCube collaboration includes: the University of Alabama in Huntsville; the University of Maryland, College Park; the Universities Space Research Association in Washington; the Naval Research Laboratory in Washington; and NASA’s Marshall Space Flight Center in Huntsville.

Canada selects Boeing's P-8A Poseidon as its new multi-mission aircraft

The partnership with Canadian industry will provide long-term economic prosperity to Canada 🇨🇦

Fernando Valduga By Fernando Valduga 11/30/2023 - 18:52 in Military

With the P-8, Canada guarantees the interchangeability of allies NORAD and FIVE EYES.

The government of Canada signed a letter of offer and acceptance of foreign military sales for up to 16 Boeing P-8A Poseidon aircraft, as part of the Canadian Multimission Aircraft Project (CMMA).

Canada joins eight defense partners, including all allies of FIVE EYES, the intelligence alliance that also includes the United States, the United Kingdom, Australia and New Zealand, and becomes the fifth NATO nation to have selected the P-8 as its multi-mission aircraft. The first delivery is scheduled for 2026.

“The P-8 will strengthen Canada's defense capability and readiness, and we look forward to delivering that capability to the Royal Canadian Air Force,” said Heidi Grant, president of Business Development at Boeing Defense, Space & Security. “Together with our Canadian partners, we will deliver a strong package of industrial and technological benefits that will ensure continued prosperity for Canada's aerospace and defense industry.”

The P-8 is the only proven in-service and production solution that meets all CMMA requirements, including range, speed, strength and payload capacity. This decision will benefit hundreds of Canadian companies and bring decades of prosperity to Canada through the support of the platform provided by our Canadian industrial partners.

The acquisition of P-8 will generate benefits of almost 3,000 jobs and $358 million annually in economic output for Canada, according to a 2023 independent study by Ottawa-based Doyletech Corporation.

“This is a very important day for the Royal Canadian Air Force and Boeing,” said Charles 'Duff Sullivan, managing director of Boeing Canada. "The P-8 offers unparalleled capabilities and is the most affordable solution for acquisition and life cycle maintenance costs. There is no doubt that the P-8 will protect Canada's oceans and borders for future generations."

The partnership with Canadian industry will provide long-term economic prosperity to Canada.

The Poseidon Team is the cornerstone of Boeing's Canadian P-8 industrial partnership, composed of CAE, GE Aviation Canada, IMP Aerospace & Defense, KF Aerospace, Honeywell Aerospace Canada, Raytheon Canada and StandardAero. The team is based on the 81 existing Canadian suppliers for the P-8 platform and more than 550 Boeing suppliers in all provinces, contributing to the company's annual economic benefit of approximately CAD$ 4 billion for Canada, supporting more than 14,000 Canadian jobs.

With more than 160 aircraft delivered or in service and 560,000 collective flight hours, the P-8 has proven capabilities for anti-submarine warfare, anti-surface warfare, intelligence, surveillance, reconnaissance and humanitarian assistance/disaster relief response.

In this view, Saturn’s icy moon Rhea passes in front of Titan as seen by NASA’s Cassini spacecraft. Some of the differences between the two large moons are readily apparent. While Rhea is a heavily-cratered, airless world, Titan’s nitrogen-rich atmosphere is even thicker than Earth’s.

This natural color image was taken in visible light with the Cassini narrow-angle camera on Nov. 19, 2009, at a distance of approximately 713,300 miles (1,148,000 kilometers) from Rhea.

The Cassini spacecraft ended its mission on Sept. 15, 2017.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

So, NaNo's got a new statement re: the AI mess.

What do we think?

"To the NaNoWriMo Community:

In early August, debates about AI on our social media channels became vitriolic. It was clear that the intimidation and harassment we witnessed were causing harm within our community of writers. The FAQs we crafted last week were written to curtail those behaviors. We wanted to send a clear signal that NaNoWriMo spaces would not be used to bully or delegitimize other writers. This was consistent with our May 2024 statement, which named a lack of civility in NaNoWriMo spaces as a longstanding concern.

Taking a position of neutrality was not an abandonment of writers’ legitimate concerns about AI. It was an acknowledgment that NaNoWriMo can’t maintain a civil, inclusive community if we allow selective intolerance. We absolutely believe that AI must be discussed and that its ethical use must be advocated-for. What we don’t believe is that NaNoWriMo belongs at the forefront of that conversation. That debate should continue to thrive within the greater writing community as technologies continue to evolve.

We apologize that our original message was unclear and seemingly random. Our note on ableism and classism was rooted in the desire to point out that, for people in certain circumstances, some forms of AI can be life-changing. We certainly don’t believe those with concerns about AI to be classist or ableist. Not being more careful about our wording was a bad decision on our part.

Our Mission is about providing encouragement to writers and cheering them on as they progress toward their goals. That remains our primary focus. In the future, we will be more transparent about the issues that we are trying to address with any messaging we provide.

Finally, we recognize that some members of our community have other questions and concerns that go beyond general context for our comments. We don’t think we can address all of these in a single communication. Additional context here is that we are a very small team (including our Interim Executive Director, who is a volunteer). We want to take the time to read through your letters with the care, attention, and concern they deserve. Please expect more in the coming weeks. 

In partnership, The NaNoWriMo Team"

Bit wishy-washy, huh?

What I hear is: "The discussion got nasty, so instead of moderating the particular, offending behaviours and engaging with the topic, we'll just not do that. We'll just not be the place for that topic."

Also, zero acknowledgement of how their AI statement just might have something to do with their sponsorship from ProWritingAid and how that means it came from anything but a neutral position.

And I'm not sure how a writing challenge community, in particular, is the place for a neutral stance on generative AI. Is it a neutral stance, for such a community in particular, to say "AI generated text is welcome"? This is a community that ought to be, explicitly, about the act of writing, not the end product of said writing. And, well, generative AI is there to do exactly that step, the act of writing. Therefore, in this context, welcoming Ai generated text (really, algorithm-generated text, no actual intelligence involved) doesn't seem like a neutral stance at all to me. "This technology makes our stated purpose for existing redundant and we welcome it because we don't judge", hmmmm...

Anyway. I don't regret deleting my account and I won't be back. I am having quite a lot of fun writing over at 4thewords, anyway.

Mars Sample Return a top scientific priority, Lunine testifies - Technology Org

New Post has been published on https://thedigitalinsider.com/mars-sample-return-a-top-scientific-priority-lunine-testifies-technology-org/

Mars Sample Return a top scientific priority, Lunine testifies - Technology Org

At the western end of Mars’ Jezero Crater, a river channel and pile of sediments resembling river deltas on Earth hold clues about how Mars evolved from a more Earth-like world to the barren, inhospitable surface seen today.

Since 2021, NASA’s Perseverance rover has collected more than 20 samples of rocks and sediments from the crater floor, delta fan and hills above it – resources that could answer crucial questions about what happened to the red planet’s climate and geology and improve understanding of our own.

But those samples could be stranded on Mars if Congress fails to provide adequate funding for the space agency to design and build the Mars Sample Return mission, Jonathan Lunine, the David C. Duncan Professor in the Physical Sciences and chair of the Department of Astronomy in the College of Arts and Sciences, testifiedm before a congressional subcommittee reviewing NASA’s science programs.

“The benefit of succeeding in bringing back rock and soil from an ancient riverbed on a planet 140 million miles away is that it will tell the world that this nation has the imagination, will and courage to accomplish just about anything,” Lunine said in written testimony. “And that message is priceless. To not complete Mars Sample Return – to leave the samples stranded on Mars – would be … a national disgrace.”

Lunine was one of four experts invited to testify at the U.S. House Subcommittee on Space and Aeronautics hearing titled, “Advancing Scientific Discovery: Assessing the Status of NASA’s Science Mission Directorate.” Watch a replay here.

Earlier this year, budget uncertainty led NASA to plan for the lower of two proposed funding levels for the mission and to lay off staff at its Jet Propulsion Lab in California. Current appropriations bills defer a decision on funding, which could range from $300 million to nearly $1 billion, while the agency reassesses the mission’s architecture.

Nicola Fox, associate administrator of NASA’s Science Mission Directorate, said that after an independent review board’s “sobering analysis” of the mission’s costs and challenges last fall, the agency would complete its internal reassessment this spring.

“It’s our willingness to acknowledge these challenges and overcome them, to conduct science in ways that have barely been imagined, that makes us NASA,” Fox testified.

Lunine called Mars Sample Return the most ambitious robotic program the United States has ever attempted, requiring challenging new technology and involving multiple NASA centers and the European Space Agency.

But having served as a member of an independent review board that examined the mission last year, Lunine said he’s “supremely confident” that it can and will be done despite budget pressures requiring difficult choices.

“It can be done because American engineering prowess is up to the task,” he told lawmakers. “It will be done because as a nation we surely will not simply walk away from a daring, highly visible and scientifically important challenge.”

Successive National Academies of Sciences decadal surveys have identified the mission as the top priority in planetary science, Lunine said, to help answer the questions: Did life begin on Mars? How did Mars dry up? Exactly when did it dry up?

Only instruments in laboratories on Earth, instruments far more precise and powerful than those carried by the Mars rovers, can precisely analyze the collected rock and soil samples to determine their composition and age, Lunine said. In the same way, the samples Apollo astronauts returned from the moon established a definitive chronology for the earliest history of the Earth-moon system – the program’s most profound scientific achievement, Lunine said. More than a half-century later, moon samples continue to be studied by increasingly capable instruments.

“The samples returned from Mars in the coming decade will be analyzed not only by scientists active today, but by scientists who are not yet born, using laboratory techniques not yet invented,” Lunine said. “These precious records of early Mars will be a lasting scientific treasure and a legacy of American technological prowess.”

Beyond the stars

(JUNO X Fem Reader)

Kaleidoscope (Chapter four)

As I stepped into Y/N's apartment, she greeted me warmly,

"Welcome to my humble abode!" Her voice was cheerful as she guided me through the door. The hallway beyond was adorned with pictures that told stories of her life. There were frames capturing moments with her family and others showcasing her at work.

As Y/N slipped off her shoes, I took a moment to glance around, observing the memories and snapshots that lined the walls. Each photograph seemed to hold a piece of her journey, from cherished family gatherings to professional achievements.

Moving further down the hallway, it opened into a spacious room where a cozy couch beckoned and a compact kitchenette stood. Next to it, a small counter space and breakfast bar were adorned with fairy lights that softly illuminated the room. The ambiance was inviting, with its soft lighting creating a sense of comfort that made me feel instantly at ease in her space.

Taking it all in, I couldn't help but appreciate the glimpse into Y/N's life that her home provided. Each detail, from the photographs on the walls to the cozy setup of the living area, reflected her personality and the moments that had shaped her world.

"So what do you think?" Y/N asked with a giggle. "I mean, you haven't seen my bedroom yet, but I think you'll like it. And if you need to use the bathroom, just let me know—it's in my bedroom."

"Also question how you eat and drink or even go to the bathroom in that suit." Y/n asked as she walked to her couch, and she took a seat.

"Ah, good question," I chuckled, following Y/N as she settled onto her couch and activated her hologram TV with the remote. "Well, the suit is actually designed to be quite versatile. It has built-in mechanisms for eating and drinking, so I can enjoy a meal or a drink without any hassle. As for the bathroom," I continued,  "it's equipped with a waste disposal system that takes care of that. I just have to be near a toilet for it to ....dump out"

"Ah, that sounds convenient," Y/N replied with a grin, clearly amused by my explanation about the suit's functionalities. She patted the space next to her on the couch, prompting me to join her. With a playful leap, I activated my space shoes, allowing me to gracefully float down and settle beside her.

As I made myself comfortable on the couch, I glanced around the room once more, taking in the cozy ambiance enhanced by the soft glow of the hologram TV. Y/N seemed at ease, enjoying the moment in her own space.

" So" I say, trying to break the silence of the moment.

"What have you been doing these last couple of years?" I ask as she slowly turns towards me

As Y/N recounted her experiences over the past few years, I listened attentively, genuinely interested in her journey since we last met. Her accomplishments in aerospace and her current role as Director of Mission Information and Technology filled me with pride for her achievements.

"That's amazing, Y/N," I responded, genuinely impressed. "You've really carved out a successful path for yourself. It's great to see how far you've come."

As she mentioned going on dates, I couldn't help but feel a twinge of surprise and perhaps even a hint of jealousy. It was a reminder that life had moved on for both of us since our previous encounter. I tried to hide my reaction, but Y/N's openness about her personal life stirred up unexpected feelings within me.

"That must have been... interesting," I managed to say, attempting to keep the conversation light despite the flurry of thoughts racing through my mind. Just thinking about what she might've done flurys my anxiety.

"PTFFF not really. I realized I wasn't into men at all" Y/N's laughter filled the room, light and genuine, washing away any tension that lingered in the air. Her words, though unexpected, were delivered with such casual honesty that I couldn't help but smile in response.

"Well, that's a revelation," I replied with a hint of amusement, trying to match her lighthearted tone. Despite the flurry of thoughts swirling in my mind, her laughter was like a soothing melody, momentarily easing my anxiety.

Y/N's laughter softened into a gentle chuckle, and she glanced at me with a playful glimmer in her eyes. "Yeah, it took a few dates to realize it," she confessed with a smile. "But after you left, there was this Juno-shaped hole in my heart that no one else quite filled like you, Juno."

Her words hung in the air, unexpected yet deeply sincere. I was taken aback, my mind racing with memories of our shared past and the emotions her confession stirred within me. Love had a way of making everything feel surreal, and here I was, with the girl I loved, sitting on her couch in her cozy apartment.

Everything around me seemed to fade into the background, leaving only her presence to fill the space between us. Her question broke through my thoughts, prompting me to speak.

"Did you get my letter?" I asked quietly, the words tumbling out as I sought to bridge the gap between our past and present, hoping she understood the depth of my feelings and the significance of what we once had.

"Yes," she answered softly, a smile playing on her lips.

Then, against the warnings in my mind, against the rules that governed our interaction, I did something impulsive. I unlocked my helmet.

"Juno? What are you doing? Can you do that?" Y/N interjected, her voice tinged with concern as she reached for my helmet. But I couldn't resist. I took it off, revealing myself to her. Y/N looked at me with a mixture of worry and curiosity, and I simply smiled.

"Juno, what are you—" Her words were cut off as my lips met hers. Letting go of my helmet to gently cup the back of her head. Drawing her closer in a moment, I felt both daring and inevitable. I closed my eyes, savoring the warmth of her lips against mine, feeling a sense of completeness that only her presence could bring.

For a brief, suspended moment, the world outside ceased to exist. There was only the soft touch of her lips, the faint sound of our breaths mingling, and the palpable tension that hung in the air. It was a risk, a leap into the unknown, but in that instant, it felt like the most natural thing in the world.

We parted for a moment, and as I looked into her eyes, I saw them light up with a galaxy of emotions. Her eyes, a captivating blend of colors, held me in admiration. One of her hands tenderly brushed against my hair, and she laughed softly.

"I remember when your hair used to be so long, Juno, and now it's so short. It suits you so well, and you look even more beautiful. You've grown into being breathtaking, and I don't understand how," she said with a giggle, her words washing over me like a warm embrace.

I chuckled nervously, my cheeks warming at her compliments. Y/N's laughter and her gentle touch were like a soothing balm to my soul, easing the tension that had built up inside me. In her presence, everything seemed to glow brighter, more vibrant, as if her energy infused life into every corner of the room.

Suddenly, the air quality registered in my mind, and I coughed reflexively. Y/N's expression turned concerned, her eyes searching mine.

It's okay, I'm fine," I reassured her quickly, attempting to ease her worry. "It's just the air. It's pretty diluted here. I'm used to the pure stuff." Her concern softened into a small smile of understanding, and she nodded gently.

"Okay, good, cause you scared the fuck out of me." she said with a hint of relief in her voice. Then her concern shifted to my well-being without the helmet. "Will you be okay without your helmet?"

"Well, they told me to keep everything on for a couple of weeks," I replied, acknowledging her concern with a faint smile. The protocols were clear, but being here with Y/N, feeling her warmth and concern, made the temporary discomfort easier to bear.

Y/N leaned over the couch to retrieve my helmet that I had dropped, then straightened up and turned to me. I assumed she was going to put it back on me, but instead, she surprised me by leaning in and planting a gentle kiss on my lips before placing the helmet back in its rightful place.

The touch of her lips lingered for a brief moment, soft and warm against mine, sending a wave of warmth through me that had nothing to do with the air quality in the room. It was a tender gesture, filled with unspoken emotions and a reassurance that transcended words. As she pulled away, I met her gaze, feeling a rush of gratitude for her presence and her understanding.

"Thank you," I whispered softly, touched by her gesture and the depth of care she showed in that simple act. I lock my helmet in place and smile.
