In Orbiter Processing Facility 1 preparations are under way to close the payload bay doors on Atlantis.

In Orbiter Processing Facility 1 at NASA's Kennedy Space Center, preparations are under way to close the payload bay doors on space shuttle Atlantis. The payload bay has been thoroughly cleaned and is ready to receive the carriers transporting the instruments and equipment needed to service the Hubble Space Telescope. Atlantis is targeted to launch Oct. 8 on the STS-125 mission to service Hubble. 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
