Do you mean originally? ULA is a 50/50 joint venture that Boeing and Lockheed Martin were forced into after almost corporate-espionaging themselves into oblivion. It owns, operates, and manufactures the factories and rockets that each

Presumably GRU was using its mined coins to spend on things like hosting for shady sites. The idea isn't to cash it out for rubles.

At first this will be true, as with many new products. But as hardware and development costs are amortized over time and competitors enter the market, we can expect prices to drop to marginal cost. That could easily be in reach of ordinary

This is true, of course, but I think the grandparent is talking about the far future. Eventually, if Musk's and/or Bezos' visions are to be realized, the average person will be a consumer — whether for space tourism, earth-to

It's a valid point. Even though we informed spaceflight observers know that these explosions were experimental (and would've happened anyway, more violently even, when boosters were expended), the average member of the public may

That's the booster landing pad. Round parachutes have little control authority — I doubt the capsule steers them at all.

Note that New Glenn, like Falcon 9, is only partially reusable — the booster is recovered but the second stage is expended. Both companies have aspirations to reuse the second stage, but few tangible plans so far. New Shepard is in some way
