WE DID IT -- Curiosity successfully lands on Mars

It was a weird, scary experience, watching the livestream of the NASA control room while Curiosity attempted to land.  They were reassuring.  Pretty much every new development, they said "Which is what we expected," or "Which is normal," which managed to mitigate the tension pretty successfully. Still, it's scary to watch like a hundred scientists -- some of the smartest people in the country -- sitting in a control room, relaying information that's almost ten minutes old, and knowing that, no matter what happens, there's nothing they could do.

I don't think there are very many times in human lives when you get moment-by-moment information about something happening, that's already happened.  It screws with my perception of causality.  Even moreso, this time, because it was the same seven minutes late for everyone. And it was on Twitter.

I imagine I'll be gathering my thoughts about this over the next several days, weeks, maybe years -- it could be a very long time before we have any clue how important this day really is.

DFTBA, Curiosity.  Best wishes.

Seven Minutes of Terror

(via Boing Boing) Scientists: You're Doing It Right.

In CrashCourse, Hank and John like to point out occasionally how terrible scientists and historians are at naming things, making the job of teachers a lot more difficult.  It's just hard to get people interested in a bunch of long series of boring names.

NASA scientists have made a video about the touchdown of Curiosity, the Mars rover currently en route to the planet.  That touchdown is seven minutes long.  It takes 14 minutes for signals to get to earth.   So, they won't know anything until 7 minutes after the entry is over.

They have named that event the Seven Minutes of Terror.

The video is great.  It's packed with information, presented in a highly dramatic fashion.  Watching this video shows how hard-won our knowledge about Mars is going to be. Once you know how hard it is, I imagine you're going to be a lot more interested in what it is we came to know.
