Congratulations to SpaceX!
After a last-half-second abort on Saturday, they fixed their little problem and lit the candle early this morning. Their launch window to ISS was instantaneous, so this is quite a big deal that they could pull it off on just the second try. It also speaks well of Falcon 9’s reliability (and repair ability).
They have a lot of on-orbit tests to do before NASA will let it anywhere near the space station, but this is a very good start.
I’m saving up $$ for my ticket!
