Technicians in the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center get ready to move an IMAX 3D camera for installation on the Orbital Replacement Unit Carrier, or ORUC, (in the background) to be installed in space shuttle Atlantis’ payload bay. The camera will record the STS-125 mission to service the Hubble Space Telescope. Space shuttle Atlantis' 11-day flight is targeted for launch May 12 and will include five spacewalks in which astronauts will refurbish and upgrade the telescope with state-of-the-art science instruments. As a result, Hubble's capabilities will be expanded and its operational lifespan extended through at least 2014. Photo credit: NASA/Dimitri Gerondidakis
