Elon Strikes Back

It will be quite amusing if Duffy has goaded him into beating SLS/Orion to the Moon.

I’m glad that he’s realized it was politically stupid to say that the Moon “is a distraction.”

    1. That was my initial thought too. But I have come to believe that that explanation gives Duffy way too much credit. The practical effect will be the same – SpaceX upshifting to Ludicrous Speed and building a complete lunar logistics architecture on its own. But I think Duffy’s little tantrum was motivated more by his uncritical acceptance of conventional DC “wisdom” about the PRC and resultant unwarranted panic about how failing to Beat the Chinese[tm] would look on his resume.

    1. Do you have a link to share?

      Kind of an amusing concept “excluding” SpaceX from exploring Ceres. If Elon sees any point in doing so, SpaceX will go to Ceres. Might be an interesting project to undertake once the Mars thing is well enough along. It would actually make reasonable sense to mount such an effort from Mars rather than from Earth anyway.

  1. I really hope they switch to horizontal landing, if nothing else for the sake of sanity.

    Landing on one Raptor is going to be tricky, as a Raptor 3 at 40% throttle still might be more of a slam landing, depending on the landing weight of the ship. That means they have to kill the engine as the ship touches down, before they know if it’s going to start tipping over. If it is tipping, they’ll need to have a second engine pre-chilled and spooling up or they’re not going to have an abort option.

    And then there’s the problem of the giant external elevator, along with a giant ladder in case the elevator jams.

    1. Based on the renders that accompanied SpaceX’s latest update, it looks as though the plan is still to land using the ring of “high-pockets” thrusters with the Raptors shutting down after managing most of the powered descent.

      I don’t think the elevator is really a problem. SpaceX has been testing it out for at lest two years. The only way it would jam is if there was a hard enough landing to tweak the whole ship. It that happens, a stuck elevator is the least of your concerns.

      1. I forgot about those. I think I try to forget about most of their design.

        The current renders more resemble penthouse apartments. I’m nto sure the interior designers are running their concepts past any engineers. The big windows continue to be featured, even though they’re a catastrophic failure mode, a large weight component, a structural weakness, and serve no purpose.

        The whole concept just makes no sense to me.

    2. I do think that there needs to be a backup for that elevator. I don’t think it needs to be a ladder though. At 1/6 G, a rope would be fine.

      The problem is designing and certifying the rope. Nasa could do it, if we’ve got a few spare years and billions. Or SpaceX could just send somebody to Walmart for a packaged coils of rope.
