  • I go back and forth on Gateway. A microgravity research station beyond LEO would be pretty helpful. Beyond that, though, it won’t literally be part of a Mars transit architecture like some long forgotten proposals, and stopping there on the way to the surface is unnecessary added delta-v. SLS+Orion also can’t fly often enough for Gateway to be its own destination or continuously crewed.

    In my perfect world, there’d be continuously crewed lunar surface and orbital stations with commercial vehicles flying public and private missions to both. One day…













  • Artemis is in an interesting place right now. It’s a bit of a mess. But it has a lot of cool and interesting parts.

    Artemis 2 might launch in 2026 with 4 astronauts for a loop around the moon. Artemis 3 might launch this decade for a lunar landing with 2 astronauts aboard a SpaceX Starship lander. A lot needs to happen for that to work, like massive progress on the Starship program and Axiom space suits, and continued progress on Lockheed’s Orion capsule.

    Artemis 2 and 3 aren’t givens anymore in the DOGE era, but they might still happen. A4+ rely on a new SLS stage from Boeing (EUS) and a new launch tower from Bechtel that are both running way over cost. Also in the mix is Lunar Gateway, a space station around the moon that isn’t really needed to get to the surface, but includes some different parts from international partners. So, who knows. We’ll see what happens.
