We’ve had more space posts than usual in the last week or so, but I wanted to give a shoutout to the Space Shuttle Discovery and its crew, for the safe landing and the successful completion of its final mission. I’m one of over 80,000 viewers watching the post-landing video stream on NASA TV over at uStream, and I think that the approaching end of the shuttle program has really reminded everyone of its amazing achievements over the past 30 years.
