STS-135 video: Narrated flow tapes

Atlantis blasted off on May 11, 2009 for the final space shuttle mission to service the Hubble Space Telescope, a dramatic flight that prepared the iconic observatory for a new revolution of discovery

On the 30th anniversary of the Challenger disaster, crew families, friends and space workers gathered Thursday to remember the 17 men and women who lost their lives on the high frontier, 14 in two space shuttle disasters and three in an Apollo-era launch pad fire 49 years ago Wednesday.

Former astronaut Bruce McCandless II, a retired Navy captain and son of a Medal of Honor winner who joined NASA during the buildup to the Apollo program, served as capsule communicator when Neil Armstrong took his historic first step on the moon and later flew in space twice during the shuttle program, died Thursday. He was 80.
