Shuttle Return Pushed Back a Week

Mission controllers have decided to give technicians an extra week to get the Space Shuttle Discovery ready for its return to flight. Originally schedule to lift off on May 15, Discovery is now tentatively set to return to orbit on May 22. One reason for the delay is to give technicians more time to test an extension to the Canadarm which will let astronauts examine the shuttle for damage while in orbit. Its launch window closes on June 3, and doesn’t open up again until mid-July when Atlantis is expected to launch.
