CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center, workers move the thermal vacuum fixture deeper into the Payload Hazardous Servicing Center. Space shuttle Atlantis is targeted to launch on the STS-125 mission Oct. 8. 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/Jack Pfaller
