At each Space Shuttle launch (and a variety of other events) NASA invites 150 people to tweet from behind the scenes of the build up to and takeoff.
For STS-134, the final launch of the Space Shuttle Endeavour, I was one of that 150.
I also returned to Cape Canaveral for STS-135, to see the final Space Shuttle lift off.
This blog contains the majority of the pictures, videos and audioboos from that experience, but also keeps a day to day eye on the International Space Station and the people who work on and for it.
