The shuttle was lifted into High Bay 3 where it was attached to its external fuel tank and solid rocket boosters on the mobile launcher platform. (NASA/Cory Huston)

# 6The tools that will be used to service NASA's Hubble Space Telescope on the STS-125 mission are displayed in the NASA News Center at NASA's Kennedy Space Center in Florida. At far right is the pistol grip tool. It can install and remove instruments, drive latches and open doors. A self-contained, high-torque drive, the tool features an on-board computer that permits users to tailor its performance to the mission demands. In the foreground are the card extraction and insertion tools to enable removal of electronic cards. At top center is the plastic version of the pistol grip tool used by astronauts during practice in the water tank at NASA's Johnson Space Center. At center left is the bit caddy. (NASA/Jack Pfaller)

# 9Two NASA T-38 jet trainer aircraft fly over the Space Shuttle Endeavour on Pad 39B at the Kennedy Space Center. After Atlantis leaves Pad A (out of frame), Endeavour will be moved from Pad B to Pad A to support the STS-127 mission. Currently, Endeavour is being prepared as a backup vehicle for Atlantis, and it will be designated STS-400 if in the unlikely event it's needed for a rescue flight. The two pictured aircraft were piloted by Jack Nickel (in jet with tail number 62, top) and Charles Justiz (in jet with tail number 24). (NASA)

Just below the "shaded" pair of windows are panels of displays and controls very instrumental in the success of the work being done on the giant observatory. (NASA)
