    This was actually a topic of my talk at UCL yesterday: can we formalize lifecycle of space habitats enough to show positive growth rate? (My answer: still need to demonstrate space mining, manufacturing and human reproduction, but looks good; even a tiny rate eats solar system)

    Once we reach a sort of compromise to work together, it becomes an interesting engineering challenge to address the visibility issue. SpaceX is full of engineers who love such challenges!

    Yesterday XB-1's wings were closed out successfully—meaning the skins and all internal structure and systems are bonded in place. We're gearing up for a full structural load test next month, followed by the wing to fuselage join in April.

    How ‘bout we start with the Central Park Five, mix in a little “there are good people on both sides” and top it off with some “shithole countries”. Mystery solved.

    Not trying to give any advice but like: Sanders fans have one super good argument (he's leading /will probably win both versions of the popular vote!—that should matter!) and one pretty bad argument (how dare Iowa release partial results!) and they should focus on the good one.

    Somnium was actually a scientific treatise in disguise, Kepler wrote it as fiction to push his heliocentric model without the church noticing. But he also considered the engineering challenges of space travel and wrote sections of proposed solutions to them.

    People forget that SF isn't a 20th century thing. The earliest SF date back to the ancient era. Plutarch for example wrote a moon landing story (which Verne liberally drew from). The first hard SF was Somnium by the great astronomer Kepler.

    Just realized this applies to philosophy and science too.

    Bernie/Bloomberg ticket: Couple of septuagenarian Jews, one a New Yorker who moved to New England and got into socialism and the other a New Englander who moved to New York and got into finance. Can this mismatched pair learn to get along and finish one last job?

  16. Amazing that educated astronomers can be this innumerate about satellites.

    I've done a lot of interviews over the past few years. Never has a journalist maliciously misrepresented my words or work. One journalist badly misrepresented me accidentally but fixed the article when I asked them to. Perhaps the trick is knowing which journalists are reputable.

    1/ I see a lot of people trying to argue that we shouldn't colonize space until we fix [problem on earth] They never explain why the two are mutually exclusive, which is clearly implied It's utterly facile. It is possible to do both.

  20. Wait... could you make a lens good enough for rough optical purposes out of amber or some other kind of tree resin?
