They launched Falcon 9 to put another sixty satellites in orbit for SpaceX’s full-coverage internet Starlink project. Fun fact: there’s a thousand up there by now (out of a projected forty thousand). Another fun fact: that’s the ninth time the company used that booster.
I may be happier about this than the ongoing work on a no-fooling rocketship. The tests of their heavy rockets are genuinely exciting and fascinating, yes. No argument there. But this stuff with the Falcons is what’s going to end up making space a hell of a lot cheaper to exploit. And I’m very happy that somebody’s doing the tedious work involved.
