Glen Reynolds and Michael Bloomberg (separately) call for cancellation of SLS in favor of a Starship-based program to go back to the moon:
Quote:
SLS requires Starship and the Lunar Gateway to get enough mass to the moon to make Artemis work. Starship can do the whole thing by itself. All things being equal, Artemis makes no sense.
But all things aren't equal. SLS costs $4 billion per launch just for the disposable rocket. SpaceX hopes to drive Starship costs down to $10 million per launch or less for a fully (and rapidly) reusable rocket.
Starship requires several launches to bring a full load of cargo to the moon because the second stage requires orbital refueling from more than one tanker. But SLS still costs 40 or 50 times what Starship would while still requiring Starship to complete Artemis and to get Lunar Gateway built.
Whatever becomes of Artemis specifically or the lunar program generally, there's zero case for SLS.
Anyway, mostly garbage comments as usual, but some are amusing. I'm not convinced the Orion capsule will really be any better than the Starliner, personally, and they have some heat shield issues with it still I believe.

That Nasa is actually planning to do that,
but get the astronauts there via SLS is pretty mind blowing. Hopefully SpaceX can start regularly launching/catching/reusing starships next year, and prove themselves capable of refueling in orbit as well. Once that happens, serious discussions can occur, imho.
