In the Orbiter Processing Facility at NASA's Kennedy Space Center, STS-125 Mission Specialists Mike Massimino (left) and Michael Good (right) check out the orbiter boom sensor system and the attached camera in space shuttle Atlantis' payload bay. Equipment familiarization 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
