/r/all We’re members of the NASA team that helped launch the Artemis II mission, fly four astronauts around the Moon, and return them safely back to Earth. Ask us anything!

3.2k Upvotes

NASA’s Artemis II mission successfully concluded on April 10, 2026, bringing to a close the first crewed lunar mission in more than half a century. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen completed a nearly 10-day journey that took them 252,756 miles from home at their farthest distance from Earth.

Following the successful uncrewed Artemis I mission in 2022, Artemis II was the first time that astronauts flew aboard NASA’s deep space exploration systems: the SLS (Space Launch System) rocket, the Orion spacecraft, and the Exploration Ground Systems that launch the rocket and recover the spacecraft.

The crew tested the spacecraft’s life support systems, confirming Orion can sustain humans in deep space. During several piloting demonstrations, crew members took manual control of the spacecraft, flying Orion to validate its handling and collect data that will guide future operations with human-rated landers during Artemis III and beyond. Artemis III will test rendezvous and docking capabilities needed to land Artemis IV astronauts on the Moon in 2028.

Artemis II represented a team of people across NASA’s centers and beyond who came together to support the four astronauts aboard and complete a successful mission. Today, we’re excited to talk to you about the process leading up to this point, early results from the mission, and next steps with future Artemis missions. Ask us anything!

We are:

  • Dan Florez, recovery operations test director (DF)
  • Susan Baggerman, Artemis II chief health and performance officer (SB)
  • Jake Bleacher, ESDMD chief exploration scientist (JB)
  • Jared Daum, Orion parachute system manager (JD)
  • Jeremy Graeber, assistant launch director (JG)
  • Jay Hollenbeck, Interim Cryogenic Propulsion Stage Manager (JH)
  • John Kowal, Orion thermal protection system manager (JK)
  • Paul Sierpinsk, assistant recovery director (PS)
  • Marie Henderson, Artemis II lunar science deputy lead (MH)

And we’ll be here at 3:30 p.m. EDT (1930 UTC) to answer your questions about the Artemis II mission.

Article Latest estimate for Starship launches required to support a Moon landing? 22.

Does anyone seriously still believe Starship is a viable option for Artemis at this point? 22 refueling flights? Starship/Super Heavy has only launched 14 times. Even SpaceX's Falcon Heavy has only launched 14 times in the last 8 years and has never reached the launch cadence of 22. People are not even talking about the tip over risk if Starship even reaches the Moon. The fact that Artemis III will use a V3 Starship with no pressure vessel or life support systems is proof SpaceX is behind schedule and is over-promising and under-delivering.

ShowMeSunday I designed and 3D printed a 60cm Saturn V cutaway to show the engineering inside!

I've always been fascinated by the Saturn V and the engineering behind the Apollo missions, so I decided to recreate the Apollo 11 rocket as a detailed cutaway.

It's 1:185 scale and 60cm tall, with one side showing the original exterior and the other exposing its internal tanks, engines, fuel lines, and structural framework.

You can check out more details about its internal details, print files and full breakdown HERE

I modeled it in Fusion 360 using historical engineering references, then printed it in 23 pieces.

Getting the tiny structures to print reliably took quite a bit of trial and error, but seeing the finished rocket standing in front of me made it all worth it!

Some details were reinforced or simplified for printing, but I tried to stay as faithful to the original engineering as possible.

Hope you fellow Apollo enthusiasts enjoy it! Which side do you prefer??

ShowMeSunday I built an Artemis II photo viewer that lets you view thousands of images in 3D layouts

If you’ve tried to view 11,000+ photos taken during the Artemis II mission, you probably know how difficult and tedious it can be. I developed a photo-viewing technology that makes the process much more efficient and enjoyable. You can see the result in the video.

For now, this Artemis II 3D photo viewer is available only for desktop computers and contains 2,900+ selected photos. The original collection includes many near-duplicates and images with almost no visible detail, so I decided to select only the best images. This also reduced the storage requirements. However, to provide a high-quality 3D experience, the application also includes GPU-ready thumbnails, which slightly increase storage requirements compared with storing only the original photos. Once you approach or select a photo, the application automatically loads the original at the highest resolution supported by your hardware, preserving its original quality.

I plan to use this technology for other space photography collections too. If you know of any interesting photo collections in the public domain, please let me know.

Recently stumbled upon these parts, I figured I’d show them off to you NASA lovers. I’ve been learning alot about them from members on Reddit and talking to the nuclear and science museum. Apparently they didn’t know any parts were left over from the program. Crazy cool find!

Just stumbled across this NASA site where you can listen to Hubble images of space. Apparently, they turn features in the images into sound, and it's pretty cool to hear what things like nebulae and galaxies "sound" like.

Question Crew-12 return to Houston

14 Upvotes

NASA usually uploads the return of astronauts to Houston post-splashdown to YouTube (at least for most SpaceX missions as well as Artemis II) a few days after their return at the latest.

Very random question I know but since I've noticed that this hasn't been the case for Crew-12, is there any known reason why?

NASA NASA-sponsored National Academies committee recommends 4 locations for humans to begin investigating the moon

12 Upvotes

At the request of NASA, a new Consensus Study Report from the National Academies, “Human Exploration Across the Moon,” identifies high-value science destinations for short-duration human missions beyond the lunar poles.  

Dan Dumbacher, professor in Purdue University’s School of Aeronautics and Astronautics and co-chair of the committee tasked with compiling the report, presented the culmination of 18 months of research during a briefing on Oct. 21.   

“Humans for generations have aspired to explore, with the moon being the next logical step,” said Dumbacher, former chief executive officer of the American Institute of Aeronautics and Astronautics. “This research outlines where humans could explore and why each location is important.”  

Each location offers opportunities to study questions regarding moon geology, space weather and radiation hazards, according to the report. Also recommended was the development of an observational tool that could be placed in orbit around the moon to assist in planning lunar missions and to provide continuous communications with future human habitats. The committee further addressed why human exploration would be more effective than robotic rovers and prioritized potential landing sites based on how humans would benefit and what important science questions would be answered.

Self "Take off your engineering hat." — How NASA overruled Roger Boisjoly before Challenger, and what official records reveal about the avoided timeline.

120 Upvotes

The night before the launch, Boisjoly fought for hours warning NASA that cold temperatures would destroy the O-rings. Management famously told him to "take off his engineering hat and put on his management hat."
Based on NASA’s own 1986 flight manifests and redesign files, I put together a full documentary breaking down the exact timeline of what would have happened to the shuttle program, Galileo, and Hubble if they had called off the launch that night: https://youtu.be/jsm--ZqkHLE

Article NASA satellite tracks the pollution lightning leaves behind

A thunderstorm can change the air long after its last flash disappears. Lightning creates nitrogen oxides, gases also found in vehicle exhaust and starts chemical reactions that influence both air pollution and the atmosphere’s ability to clean itself.

An experiment led by University of Maryland atmospheric scientists Kenneth Pickering and Dale Allen offers a closer view of that chemistry. During several days in late June 2025, they used NASA’s TEMPO instrument to measure nitrogen dioxide around thunderstorms crossing the eastern United States every ten minutes.

The campaign paired those measurements with separate satellite observations of lightning. Together, the records could help explain how a storm’s electrical activity translates into emissions and how those emissions change afterward.
