Finally discovery has been launched

The shuttle Discovery blasted its way into orbit on Saturday through wispy clouds against blue skies on its way to deliver a bus-size laboratory to the International Space Station.

… The laboratory, the $1 billion Kibo module, is the largest and the second part of three shuttle payloads that will bring the full Kibo assembly up to the station.

It will be the largest “room” on the station, and will eventually include an exposed area, like a back porch, where some experiments will be exposed to the harsh vacuum and temperature extremes of space.
