The 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. On space shuttle Atlantis’ STS-125 mission, Hubble will be serviced for the fifth and final time. The flight will include five spacewalks during which astronauts will refurbish and upgrade the telescope with these state-of-the-art science instruments. As a result, Hubble's capabilities will be expanded and its operational lifespan extended through at least 2014. The payload includes a Wide Field Camera 3, fine guidance sensor and the Cosmic Origins Spectrograph. Launch is scheduled for 2:01 p.m. EDT May 11. Photo credit: NASA/Jack Pfaller
