Gregory C. Johnson examines the cockpit window on space shuttle Atlantis checking for sharp edges.

In the Orbiter Processing Facility at NASA's Kennedy Space Center, STS-125 Pilot Gregory C. Johnson examines the cockpit window on space shuttle Atlantis, checking for sharp edges. The inspection is part of the crew equipment interface test, which provides hands-on experience with hardware and equipment for the mission. Atlantis is targeted to launch Oct. 8 on the STS-125 mission to service the Hubble Space Telescope. The mission crew will perform history-making, on-orbit “surgery” on two important science instruments aboard the telescope. After capturing the telescope, two teams of spacewalking astronauts will perform the repairs during five planned spacewalks. Photo credit: NASA/Kim Shiflett
