Endeavour to Launch Wednesday, LRO/LCROSS on Thursday

NASA MISSION UPDATES

At NASA’s Kennedy Space Center in Florida, space shuttle Endeavour is set to launch on its STS-127 mission at 5:40 a.m. EDT Wednesday, June 17.

Endeavour’s planned June 13 liftoff was postponed because of a leak associated with the gaseous hydrogen venting system outside the shuttle’s external fuel tank. The system is used to carry excess hydrogen safely away from the launch pad. Technicians have removed and replaced the ground umbilical carrier panel and seal, and repair work should be complete by 3 p.m. Tuesday.

“Our teams have been working very hard over the last couple of days to get this piece of equipment fixed,” said NASA Test Director Steve Payne during a briefing Monday afternoon. “Endeavour is in good shape and the teams are excited to be back to working toward a launch on Wednesday morning.”

According to Shuttle Weather Officer Kathy Winters, the weather is expected to cooperate with NASA’s launch plans, with an 80 percent chance of favorable weather expected.

As a result of the rescheduling of space shuttle Endeavour’s STS-127 mission for June 17, the Lunar Reconnaissance Orbiter and Lunar Crater Observation and Sensing Satellite are now set to lift off together aboard an Atlas V rocket on Thursday, June 18.

There will be three launch opportunities from Cape Canaveral Air Force Station in Florida at 5:12 p.m., 5:22 p.m. and 5:32 p.m. EDT.
