NASA Delays Launch of Shuttle Endeavour by 10 Days to Avoid Space Traffic Jam

NASA has delayed the last launch of the shuttle Endeavour toward the International Space Station by at least 10 days, to April 29, in order to avoid a space traffic jam with an unmanned Russian cargo ship, also headed for the orbiting laboratory later this month. Endeavour is now targeted to blast off on its STS-134 flight on Friday, April 29 at 3:47 p.m. EDT (1947 GMT), NASA officials said. The decision to postpone the launch removes a scheduling conflict with a Russian Progress cargo ship, which is currently scheduled to launch April 27. The robotic Progress vehicle will arrive at the station on April 29. More
