Maybe also seriously threaten Boeing with cancelations and restrictions for their constant failures and corruption. We've had the espionage scandal that forced the formation of ULA, SLS's extreme delays and overruns, supressing Vulcan's capabilities to prevent it from impinging on SLS's blank check, Starliner's inability to deliver (and at this point it seems unlikely the station will be around long enough for their 6 flights), and the scandal that caused their disqualification from the original HLS bid.
Starship is being painted as the sole blocker in Artemis, but I can't think of any component of Artemis that has any contractors delivering competently and on-time.
We still haven't heard anything about the status of the EVA suits, which the US has an even worse track record on than rockets. My understanding is that they haven't been able to build and bring a new suit into use, for 25+ years now, and not due to a lack of spending.
SLS Block 1: >27,000 kg (59,500 lb)
SLS Block 1B: 42,000 kg (92,500 lb)
SlS Block 2: >46,000 kg (101,400 lb)
Vulcan Centaur: 12,100 kg (26,700 lb)
New Glenn: 7,000 kg (15,000 lb)
Orion crew module by itself weighs 10,400 kg (22,900 lb), the service module is 15,461 kg (34,085 lb).
Orion is a heavy spacecraft. SLS, like or not (I don't), it has a lot of lift. Unless you're sticking an Orion inside of a Starship (lol), Orion basically dies with SLS.
Supposedly, as of a week ago, LM sees at least some possible routes to having Orion without SLS to not outright give up on the idea, but doesn't have specifics for now: https://arstechnica.com/space/2025/10/once-unthinkable-nasa-...
