STS-122 Astronauts Prepare to Leave Station
The STS-122 and Expedition 16 crews are scheduled to bid one another farewell before the hatches close at 12:15 p.m. EST between space shuttle Atlantis and the International Space Station. Atlantis is slated to undock at 4:27 a.m. Monday.
Prior to hatch closure, the two crews will continue outfitting racks and systems inside Columbus.
STS-122 arrived at the station Feb. 9, delivering the European Space Agency’s (ESA) Columbus laboratory to the station. The crews installed Columbus Feb. 11 and conducted three spacewalks to prepare Columbus for its scientific work. They also replaced an expended nitrogen tank on the station’s P1 truss.
In addition, Atlantis delivered a new station crew member, Flight Engineer Leopold Eyharts, an ESA astronaut. He replaced astronaut Daniel Tani, who is returning to Earth aboard Atlantis.
The orbiter is scheduled to land at Kennedy Space Center, Fla., Wednesday.
