In the Vehicle Assembly Building, Mike Ravenscroft, with United Space Alliance, points to some of the foam repair done on the external tank of Space Shuttle Atlantis. Holes filled with foam are sanded flush with the adjacent area. In late February, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The launch now is targeted for June 8.

NASA, Boeing and United Launch Alliance officials discuss the Crew Access Arm under construction at a yard near NASA's Kennedy Space Center in Florida. The arm and white room are being built to bridge the space between the Crew Access Tower and the hatch to Boeing's CST-100 Starliner spacecraft as it stands atop a ULA Atlas V rocket at Space Launch Complex 41 before flight. Partnering with NASA's Commercial Crew Program, Boeing is one of two companies building a new, privately owned and operated space system to carry astronauts to the International Space Station. The speakers are, from left, Lisa Loucks, Launch Site Integration lead for Boeing; Steve Hirst, Launch Operations Group for ULA; Chris Ferguson, former astronaut and deputy program manager of Boeing's Crew and Mission Operations, Gary Wentz, vice president of Human Launch Services for ULA, and Mike Ravenscroft, Launch Site Integration manager for NASA's Commercial Crew Program.
