Payload at the Pad

At NASA's Kennedy Space Center in Florida, the payload for space shuttle Endeavour's STS-134 mission arrived at Launch Pad 39A last night.

Crews will move the payload into the Payload Ground Handling Mechanism, or PGHM, today. The rotating service structure will then be rotated back around the spacecraft early tomorrow morning. The payload is set to be loaded into Endeavour's cargo bay on Friday.

At NASA's Johnson Space Center in Houston, the STS-134 crew will practice undocking and rendezvous procedures.

Launch of Endeavour to the International Space Station is targeted for April 19 at 7:48 p.m. EDT.
