Awwal 01, 1432, April 05, 2011, SPA -- The National Aeronautics and Space Administration (NASA) on Monday delayed its next space shuttle flight, citing a conflicting Russian launch. Shuttle Endeavour was supposed to launch on April 19, but the launch is now scheduled for April 29. NASA announced the postponement on Monday, after meeting with the Russian Space Agency and other space station partners on Saturday and Sunday. The flight will be the last one for Endeavour, and the next-to-last shuttle mission for the space shuttle.
