3... 2... 1... Liftoff

The space shuttle Discovery sets off on its final mission (STS-133) today at 4:50pm. The Discovery will complete an eleven-day voyage to the International Space Station and then enjoy a long retirement, maybe work on its golf handicap, putter around in the garage, the usual stuff. Follow minute-by-minute coverage of the events at Kennedy Space Center, read about the shuttle's past missions, and watch the launch at NASA's Launch Blog.
