Inside the White Room on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-125 crew members review procedures for entry into space shuttle Atlantis with a trainer (right). From left are Pilot Gregory C. Johnson, Mission Specialist Megan McArthur, Commander Scott Altman, and Mission Specialists Andrew Feustel and Mike Massimino. Not seen clearly are Mission Specialists Michael Good (left) and John Grunsfeld (right). Space shuttle Atlantis' 11-day flight is targeted for launch May 12 and will include five spacewalks to 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/Cory Huston
