    If that's the case, then maybe there IS a good reason for it after all. They'll probably need all the energy they can get.

    I don't think it's fair to count destructive tests during the R&D phase as "failures". Even after the first successes there's a grey zone. Perhaps when they stopped referring to it as "experimental landing" and simply "landing" would be a good starting point to count failures/ successes.

    Hmmmm....is that a falcon?

    Right. It's not exactly rocket science

    Yeah, they didn't even bother to do the countdown this time.

    Given how much effort they put into their PR, I'm guessing that they DO care. Maybe those people aren't directly their customers, but they have an influence on the people who are.

    Probably, I didn't realize that they made ropes out of the stuff. Makes sense though.

    Based on this link, I estimate a kevlar cable would weigh about 5 kg/m for a 450 ton BFS at 1g. I don't know how much you want, maybe 100 m? So that's 500 kg, and that's probably waaaay over-engineered.

    Yeah, maybe, but it's tall and ladders aren't the safest things. But indeed, it will be on Mars anyway. Perhaps I overanalyzed. Still, if there is a big open common area, having space in 3d would be, well, more space.

    There's that, but there's also the sudden need for stairs and things like that. I don't know how much space that would take, but I imagine it's a lot.

    An elegant idea. Unfortunately, a big drawback with it, or pretty much any artificial gravity idea, it that it would drastically reduce the amount of usable space you have.

    Same article states that they've already deorbited a large number of the old-school versions of the satellites. RIP Iridium flares

    I'm guessing that the boat is cheaper than the fairing (half).

    If the cost-to-orbit is so cheap, maybe it's no big deal to simply add a super-cheap propulsion, like a compressed air tank with a de Laval nozzle, for example. I wonder how much delta v you could get out of something like that.

    Yeah, it looks like they got confirmation of booster destruction, but immediately after a "but don't say anything!!"...and then you can kind of see them backpedal and try to hide their emotions. As for the free ride on the Falcon, would have been a perfect opportunity to test that Cannae drive and put the whole thing to bed. Most of the arguments against doing just that seemed to be of the "putting it in space is too expensive" variety.
