Space Shuttle Atlantis lifts off on the 121st shuttle flight, a 13-day mission to deliver another laboratory module to the International Space Station. The European Space Agency’s Columbus lab module is ESA’s contribution to the station, and is attached to the recently-installed Harmony node over the course of three spacewalks. Aboard Atlantis for her 29th flight are Commander Steve Frick, Pilot Alan Poindexter, and mission specialists Stanley Love, Leland Melvin, Rex Walheim and Hans Schlegel. ISS Expedition 17 crewmember Leopold Eyharts travels to the station aboard Atlantis, while ISS Expedition 16 crewmember Daniel Tani returns to Earth on the shuttle in his place.
