NASA Mission Control Center said Atlantis' landing opportunity at the Kennedy Space Center, Fla., is scheduled for 6:21 a.m. EDT (1021 GMT) Thursday.

    During the first inspection, the astronauts used cameras on the shuttle's robotic arm to conduct scans. Imagery specialists and engineers reviewed the data from Wednesday's scan and previous activities. They did not see any areas of concern from the first inspection.

    The astronauts then attached the orbiter boom sensor system to the arm and performed additional inspections. The boom allowed engineers to inspect areas that could not be seen with the arm above. Specialists will continue to analyze the data.

    Mission managers decided to wave off Atlantis' landing attempts on Tuesday, in order to allow the crew to inspect the orbiter. The extra scans are being used to ensure that all of Atlantis' critical equipment is in good shape for landing.

    To get ready for landing, the crew may pack up gear and stow the Ku-Band antenna later on Wednesday. The antenna is used for television coverage.

    Forecasts for Thursday call for acceptable weather at the Florida landing site.

    Atlantis' mission has resumed the construction of the International Space Station. Atlantis delivered the new integrated truss to the station on Sept. 11. The Atlantis crew and Expedition 13 on station, used the shuttle and station robotic arms to attach the truss to the orbital outpost. Then Atlantis astronauts conducted three spacewalks in four days, to prepare the truss and its solar arrays for operation. Enditem
