I've watched that video so many times now. NASA released an 'official version' that plays back at the actual speed of the descent, with voiceover from mission control, but the quality didn't seem to be as good as what was in that clip you linked.

I'm so thrilled by the Curiosity mission. I have the latest images archive bookmarked and check it at least once a day.

Semi-related, I was very disappointed when I saw the headline "Who knew? Curiosity photos show Mars teeming with UFOs" hit several of my news aggregators. I'd like to shout out a big hearty "fuck you" to MSNBC for muddying the waters with garbage like that.
