Going to see Captain Archer play Abraham Lincoln at Ford's Theater tonight, so that's going to be an experience.

Long and very informative thread! I learned a bit.

DRACO is a space term that means:
1. This experimental mission
2. Thrusters on Crew Dragon
3. The telescope on DART
4. The drill on Dragonfly
5. The experimental NTR propulsion demonstration mission
Any I'm missing?

After visiting Bletchley Park last week, had to rewatch The Imitation Game. Even worse than I remembered. So inaccurate and not even in mostly understandable ways, but *especially* so with the sheldonization of Turing. Man deserved so much more than that movie. Hopefully one day he'll get it.

Of all the things to try and verify the software for, this one would hurt the most. https://oldbytes.space/@kenshirriff/112990160257378951

You have a problem, and think, "I know, I'll solve this with a distributed system!"
Now you have N problems.

My car has a new software update, with, and I quote, "software enhancements and bug fixes". That's the extent of the detail.
At this point I think I will release the next Dragonfly flight software build with just that as the release notes and see if anyone complains.

I'm not sure. In 2015 even I think that source selection statement is entirely reasonable. Obviously wrong in hindsight, and arguably wrong in the moment, but still defensible. And there was a reason for two providers, and in that sense I think NASA has done exactly the right thing there - one has a problem and they still have a working transport capability.

Apropos of nothing, reading the NASA CCtCap source selection statement from 2015 today, picking Boeing and SpaceX to develop crew capsules.

I think the last two debuts of new rockets (Vulcan and Ariane 6) both launched successfully on their first attempt, no scrubs no problems?
