Artemis is a joke. You can tell this is politically motivated by their stance on SLS. If they were serious they would give Spacex the SLS contract for being years and years behind schedule.

If they were serious, they'd properly look into ending SLS after the ones that are being built are launched, cancel the upgrade, go after the company that spent the entire launch tower budget before even starting construction, open up bids for rockets to fly Orion (probably Vulcan or New Glenn IIRC), and sort out their space suit issues.

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.

Payload capacities to trans-lunar injection (source wikipedia):

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.

New Glenn at least claims to eventually be able to put 45,000kg to LEO. Once in orbit, refueling or docking boost stages can come into play. With Vulcan, I have mainly heard of proposals involving modifying Orion to dock the service module in orbit after separate launches.

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-...
