undocking, the two spacecraft were orbiting above the Southern Ocean southwest of Perth, Australia. The shuttle, guided by pilot Tony Antonelli, backed away from the ISS to a distance of about , at which time Antonelli began conducting a fly-around of the space station, so that crew members on both the ISS and shuttle could get photos of both vehicles. Once the fly-around was complete, the shuttle crew conducted two separation burns to move Atlantis away from the space station. May 24 (Flight day 11 – Late inspection) The crew of Atlantis awoke on flight day 11, and after a couple of hours of personal time, began the late inspection of the shuttle's wing leading edges and nose cap. The crew finished the scans about two and a half hours ahead of schedule. By 09:50 UTC, they had finished their look at the right wing, by 10:52 UTC the nose cap survey was complete, and the left wing survey was finished at 11:17 UTC. The TPS survey was done using the shuttle's robotic arm and its OBSS extension. While the scans were going on, some of the crew stowed items that were no longer needed or were transferred right before undocking. Spacewalkers Mike Good and Steve Bowen cleaned up and stowed their spacesuits for landing. The latter part of the crew's day was spent with some off-duty time. May 25 (Flight day 12 – Landing prep)Atlantis' astronauts devoted flight day 12 to preparing for the shuttle's landing. The crew executed standard day-before-landing activities. Commander Ham, Pilot Antonelli and Mission Specialist Good began the flight control system (FCS) hot-fire checkout at about 1:40 am EDT, operating the rudder and flaps that would control Atlantis' flight through the atmosphere to the KSC runway. That complete, Ham and Antonelli fired each of the shuttle's 44 attitude control thrusters, which were designed to orient Atlantis in space as it descended from orbit and through the upper atmosphere. Both these tests were completed successfully. All STS-132 crew members worked at various times throughout the day to stow items in the cabin to prepare for landing. They also gathered for a 30-minute deorbit briefing at 5:40 am EDT. Immediately afterward, the crew talked with representatives of the Colbert Report, ABC Radio Network, and WEWS-TV of Cleveland, Ohio. Late in the day, Mission Specialists Reisman and Sellers stowed the Ku band antenna in Atlantis' cargo bay. May
