For the final time in space shuttle program history, both launch pads at Kennedy Space Center are occupied. Endeavour was rolled to pad 39B before sunrise last Friday, taking its perch a mile-and-a-half north of pad 39A where Atlantis stands poised for the last mission to service the Hubble Space Telescope. These panoramas shot Friday show Endeavour at dawn and the mid-afternoon spectacle of seeing double shuttles.

Improved odds ease NASA's space debris concerns
Even factoring in a recent satellite collision, an analysis of the threat posed by space debris at the Hubble Space Telescope's 350-mile-high altitude shows the crew of shuttle Atlantis, scheduled for launch May 12 on a mission to service the observatory, will not face a dramatically higher risk of potentially catastrophic damage.
