Is art allowed on this subreddit as long as it is related to the SLS or Orion spacecraft?

I have some ceramic models of the SLS and Orion spacecraft I’ve been wanting to show, but I haven’t found any subreddits for them. r/art, for instance, only allows one image.

Am I alarmist for being worried about SLS Block 1B?

Given the election results, I fear that SLS is gonna be on the chopping block. EUS I’d think is first to go, along with gateway. Any thoughts?

Will Block 2 be the last major version of SLS?

Block 2 with EUS and BOLE boosters is enough to meet the needs of manned or cargo lunar missions of the Artemis program or even manned missions to Mars (building MTV with Block 2 Cargo, transporting people to MTV with Block 2 Crew or even using Orions in Martian orbit to explore the moons/or meteorites around Mars, send large equipment to Mars, etc.)

So does this make Block 2 the last major version of the SLS? Maybe there will be Block 2 V2, Block 2 V3 etc but no Block 3?

All I could think of for a Block 3 is SMART reusability like the Vulcan Centaur will do, ie a small section at the bottom of the SLS core would detach along with the engines, and use an inflatable heat shield for re-entry and splashdown. Or BOLE+ boosters that will be able to provide enough thrust to the SLS so that they can be made reusable, meaning they don't need to be made expendable for extra thrust. So they can be reused in a direct or indirect way.

Maybe in the future partial reusability will make sense when a large launch rate is achieved

Thoughts on Artemis 3 alternatives

I've seen talk that if Starship HLS is not ready for Artemis 3 that the mission should be changed to one that remains in low earth orbit and simply docks with Starship before heading home. I don't really understand why this is being proposed. It seems that, should HLS be ready in time, NASA is perfectly fine going ahead with a Lunar landing, despite Orion never having docked with Starship before. Instead, (and I know my opinion as a stranger on a space flight enthusiast subreddit carries a lot of weight here), I think Artemis 3 should go to the Moon regardless of weather or not HLS is ready. Artemis 2 will being going to the Moon, yes, but only on a free-return trajectory. Artemis 3 could actually go into Lunar orbit, a progression from Artemis 2, and even break the record for the longest ever crewed flight beyond LEO, currently held by Apollo 17 at 12.5 days (Orion is rated for 21 days). What do you think?
