On May 23, 2010 the American Space Shuttle "Atlantis” (STS-132 flight) undocked from the ISS at 15:22 UTC.
Atlantis spent 7 days, 0 hrs, and 54 minutes docked to the orbiting laboratory.
Pilot Tony Antonelli flew the shuttle one lap around the station to document its new configuration that includes the Rassvet module the STS-132 mission delivered. Atlantis' other crew members took photos of the station.
