Mission STS-128 finally got off the ground with the great nighttime launch of shuttle Discovery Friday night. I was unable to watch NASA TV as I usually do for a launch, as I was busy directing a flight of students in the Magellan Simulator at the Space Center. However, the NASA TV replays got me caught up on events and the flight has proceeded as normal so far.
