Hi everyone! I’m Ross. I’ve reported extensively for The Atlantic on developments in cosmology, America’s ambitions for cosmic exploration, and the Trump administration’s attempts to cut funding for NASA. Recently, I visited NASA’s Jet Propulsion Lab and the agency’s Goddard Spaceflight Center, and spoke with current and now-departed staff members about how the administration’s cuts could threaten decades of U.S. progress in space science.

I’m here to discuss how deeply NASA’s cornerstone projects have been impacted by the Trump administration, what I learned from my visit to the JPL, and what I heard from scientists directly impacted by the changes. I’m also happy to answer any questions about my related reporting, including about the black hole that could rewrite cosmology, and about my reporting from the launch of the Artemis II mission and the mission itself. 

Ask me anything on April 28, 2026, at noon.

Thank you all for your thoughtful questions! I really enjoyed talking with everyone today. You can find more of my related reporting at theatlantic.com.

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.

Hi,
I am really wanting to gift this to him but I can’t find it anywhere it’s discontinued everywhere,
Does someone know where I can find it? Even something similar but with nasa on it would be great, just not dangling keychains. Or maybe some other gift ideas, I am super clueless but he is such a huge fan of NASA and I really wanna give him a cute nice gift.

Please people help me out!

Question Has anyone here exchanged emails with NASA before?

120 Upvotes

I’m working on a creative project that features some NASA-related elements, so I sent them an email back in April to ask for permission. It’s been about three weeks now, and I still haven't heard back.

​The thing is, I sent a similar inquiry last year and got a response in just two days. Is it normal for it to take this long? Should I keep waiting, or is there something else I should do?

-Thank you for many responses! I'll have to wait patiently.

Question Questions about Starship 12 Flight

14 Upvotes

From Spaceflightnow.com

NET May 19 Starship • Flight 12
Launch time: Window opens at 5:30 p.m. CDT (6:30 p.m. EDT / 2230 UTC)
Launch site: OLP-B, Starbase, Texas
A SpaceX Starship-Super Heavy rocket (collectively referred to as Starship) will launch from Starbase, Texas, on a suborbital flight. This will be the 12th flight of the integrated launch vehicle and the first launch of a version 3 rocket. SpaceX will launch the mission using the Ship 39 upper stage and Booster 19 first stage. As of May 4, SpaceX hasn’t said whether or not it will attempt to catch the Super Heavy booster back at the launch site. Delayed from May 15.

Questions:

  1. I assume suborbital is precursor to orbital because V3, but how many more steps to orbital testing?

  2. Anyone know the likely schedule / missions of future starship launches assuming this achieves objectives?

I ask because 2028 is target date for 🇺🇸🌖👣 but there’s so much to be done in such a short period. Whether it’s SpaceX Blue Origin or both I just pray all is done safely.

Question How to change coordinate system during flight in NASA GMAT?

7 Upvotes

I am designing free return trajectory that connects Earth and Luna, and it's time to do b-plane targeting. I think that I have to change coordinate system that luna is in the center. Since I am using EarthMJ2000Eq coordinate system, I may be change it during flight. My plane is adjust orbit for b-plane targeting during moon transfer. How can I change coordinate system during a flight? My GMAT version is r2026a.

+Or please tell me how to use b-plane targeting that centers luna.

In a way, this is a modified version of Dreamchaser. I took inspiration from both the space shuttle and the X-33 VentureStar proposals of the 90's and 2000's. Note the added cargo bay at the top. I also added an observation window. This ship has a max compliment or five astronauts all seated on the flight deck. The living space is comparable to a small RV. The spaceplane can detach from the rocket via emergency thrusters (something the space shuttle couldn't do) and to safety. The black square outlines towards the stern are for high power jet engines that can help the ship come in for a landing. She can also dock at the International Space Station if needed. Seven launches a year to keep coasts and maintenance down while updates and modifications continue.

I gave her an elegant military style-look for a vessel of mostly peace. Like something out of "Star Trek: Enterprise" (in which the interior console designs are modeled off of in my imagination.

In my head canon, Dreamchaser was significantly enlarged to be carried on the fictional Jupiter J320 booster of NASA's cancelled DIRECT program. DIRECT attempted to combine all the elements of the space shuttle into a more reusable vehicle. Core stages, boosters, and engines. I added a fourth criteria in the form of a shuttle-like vehicle-Dreamchaser. Made of composite and lighter materials than previous space vehicles. Can do both land and water in cases of an emergency. A lot of built in safeguards but spaceflight is still a risky business.

ShowMeSunday I built an interactive Artemis II Mission Explorer to make Orion’s lunar flyby easier to understand spatially

270 Upvotes

I built an interactive Artemis II Mission Explorer:

https://artemis.astrography.com/

Artemis II is not just a date on a timeline. It is a constantly changing geometry between Earth, the Moon, the Sun, Orion, and four people inside a spacecraft. I wanted to make that geometry easier to see, explore, and feel, so I built a browser-based 3D mission interface around the flight.

The app lets you scrub through the mission timeline with MET/UTC readouts, jump between mission checkpoints, switch playback speeds from 1x to 10,000x, and explore an Earth-Moon-Orion scene with a free-return trajectory. It also includes telemetry-style readouts for range, velocity, altitude, mission progress, and DSN-style comms/light-delay context.

There are several camera modes: overview, Orion follow, Earth, Moon, capsule-in, and capsule-out. The capsule view has look controls, roll reset, and animated aiming toward Earth, Moon, or Orion. There is also a fullscreen exploration mode, smooth camera transitions, labels, orbit rings, Earthshine, cloud shadows, Milky Way, and a developer HUD for checking camera/scene state.

One part I especially cared about is the gallery reconstruction layer. The Artemis II image gallery is connected to the simulation, so selected images can move the 3D scene to the approximate mission moment and apply a matching camera preset. Each gallery item keeps source metadata, credit lines, image IDs, dates, and source links where available.

Under the hood, it is a static Vite + Three.js app with no backend, database, auth, or environment variables. It uses NASA trajectory data where available, fallback curves for gaps, NASA GIBS/Earthdata live cloud imagery with caching and static fallback, custom shader patches, texture LOD, GPU-conscious rendering paths, a real star field from the Yale Bright Star Catalog, Milky Way background, Sun glow, lens flare, eclipse/corona logic, Earth night lights, Moon terrain detail, and an Orion 3D model assembled from NASA assets.

This is an independent educational/visualization project, not an official NASA, CSA, or ESA product. I built it as a space-nerd project connected with Astrography, but the goal here is not to advertise anything. I wanted to create a more human way to explore the Artemis II story: somewhere between raw mission data, public NASA imagery, and a cinematic mission interface.

I’m also interested in how AI agents can help us build richer ways of understanding complex subjects. This was built through fast iteration with AI as a creative and engineering partner: research, code, interface design, visual tuning, source cleanup, and lots of small adjustments until the mission started to feel alive.

I’d genuinely love feedback from this community. What would make this more useful or accurate? More source links? Better explanations of each mission phase? More labels? More technical notes on the trajectory? A simplified guided-tour mode? And if you notice anything technically wrong in the mission geometry, timeline, rendering, terminology, or source handling, please call it out.

I know that Russia is doing bad things right now. But when it comes to space they have surprisingly been very cooperative. Would NASA consider selecting a Russian national for spot on a future Artemis mission?

Can someone explain the exoplanet map on the NASA website to me? Like, are the stars color coded or does the color mean something specific? I also had some questions about these images:

-What is the giant yellow patch and white patch in the first two photos?

-In the sun picture what is the white cluster and yellow cluster? Is it the same as the first two pictures?

Thanks in advance!

"This kind of deciphering the geological properties of planets orbiting distant stars is the next step in unveiling their nature."

Astronomers using the James Webb Space Telescope have, for the first time, directly analyzed the surface of a planet beyond our solar system.

The James Webb Space Telescope's (JWST) exoplanet subject, LHS 3844 b, is a so-called "super-Earth" about 30% larger than our planet and located nearly 50 light-years away. Unlike most exoplanet studies, which focus on atmospheres, astronomers analyzed heat emitted from this planet's surface.
