May 18, 2009--Seeming to float above the Gulf of California (Golfo de California), space shuttle astronaut Andrew Feustel (center) participates in the fifth and final spacewalk of NASA's last hands-on repair mission to the Hubble Space Telescope.

The mission successfully installed two new science tools, fixed two ailing ones, and replaced batteries and gyrators.

After weather-related delays, the returning shuttle Atlantis touched down on May 24—two days late but safe—at Edwards Air Force Base in California.
