Artemis Moon Program

Philip Sloss has a new update for Artemis III:


In the latest round-up video, a look at the signs of Artemis activities and progress that NASA published in the past week or so, and how much of that activity is a reminder of long-standing questions about other work needed to fly more astronauts and missions to the Moon.

NASA posted imagery of Artemis III preparations at the Kennedy Space Center, where the SLS boosters are being stacked, the SLS Core Stage RS-25 engines are now installed, and flight crew training is in progress. New pictures and video were published almost daily in the past week, but we have yet to see work on the other two spacecraft and rockets in the Artemis III flight plan.

There's similar mixed signals/messaging when looking at other recent Artemis work disclosed publicly, for example, the start of an Artemis VI SLS build that is simultaneously uncertain to either be finished or fly.

And there's still just as big unknowns about lunar lander and lunar surface spacewalk suit development, with both activity and progress a mystery. (At the end of the week, Blue Origin published another set of renders of their Blue Moon spacecraft concept, while their mission profiles and most of the flight hardware said to be in production remain secret.)

Although this is about the project Apollo mobile-launcher used to launch the Saturn V I posted it here as it has some relevance into the Artemis/SLS ML-1 and ML-2 platforms in regards to their design, complexity and construction:


Before Saturn V could leave Earth, NASA had to build something that would stay behind. Weighing approximately 12 million pounds, the Mobile Launcher was far more than a simple platform—it was a mobile part of the launch complex that carried the tower, access arms, swing arms, and hold-down mechanisms needed to support Saturn V from the VAB to ignition.

In this document-based engineering breakdown, we look at the design, steel erection, and system integration of the Mobile Launchers at Launch Complex 39:​

• Why NASA shifted from pad-assembly to mobile launch operations
• Structural steel fabrication by Reynolds, Smith & Hills and Ingalls Iron Works
• The 9 service arms, hold-down arms, and tail service masts
• How AS-500F verified Pad 39A before Apollo 4
• The activation struggles of 1966 and integrated systems testing

I wonder when a similar video will be made about the SLS launcher's ML-1 and ML-2 launch-pads

Those engine vertical-installers are legacy project Apollo hardware.

i was surprised to see its axis supporting the engine was moving radially independently from the rolling frame. That should make for some interesting design choice to see more in details!
 
More indecision concerning Washington and NASA management over the direction of Artemis, from Philip Sloss:


Approaching the final quarter of the 2026 calendar year, at the end of an otherwise slow news week, a look an accumulating list of questions about NASA's Artemis plans and schedules for the rest of this decade and the indecision in Washington about plans for the next one.

Sounds like both ESA and Canada could be frozen out of this. Though individual European countries might have a chance like we see here with Italy.

The problem is I imagine with Nasa canceling a bunch of things with partner investment in them, I imagine a lot of partners are a little hesitant to invest heavily in things with "optimistic" timelines.

NASA chief: I’m only interested in “good deals” from international partners
“There was absolutely a time where we were trying to make everyone happy.”
