“Following discussions among the International Space Station partners on Sunday, NASA has targeted the launch of space shuttle Endeavour’s STS-134 mission for 3:47 p.m. EDT on Friday, April 29. The delay removes a scheduling conflict with a Russian Progress supply vehicle scheduled to launch April 27 and arrive at the station April 29.”
