Maybe only tangentially related to SpaceX, but an amazing sign of the space revolution yet to come — thanks in large part to SpaceX for lowering the cost to get to orbit.
About the re-entry vehicle: "…we’re building like 1986 Toyota Corolla that is meant to be less than a million bucks a pop, quickly refurbished, and then shot right back into space.” How cool!
My laymen’s thought is that Chrystal growth requires nucleation points in the solution to start it off. In uG I guess the impurities required for the nucleation would be more evenly distributed and it means that as the crystals grow they would be more uniform. Having said that, I expect they just crush it all up in to a powder anyway so maybe that’s not the case.
