Shuttle Endeavour was supposed to blast off April 19 with the husband of wounded congresswoman Gabrielle Giffords, Mark Kelly, at the helm. The launch is now scheduled for April 29.
NASA announced the postponement Monday, after conferring over the weekend with the Russian Space Agency and other space station partners.
It will be Endeavour's final flight and the next-to-last shuttle mission
An unmanned Russian cargo ship is set to blast off at the end of April. NASA did not want the craft docking at the International Space Station while Endeavour was still there.
