Discovery’s Final Mission Extended By One Day NASA said on
Tuesday that space shuttle Discovery’s mission to the
International Space Station (ISS) has been extended an extra day
and is now scheduled to return back to Earth on March 8. "The
extension day will be devoted to emptying the Permanent
Multipurpose Module and moving supplies between Discovery and
station," NASA said in a tweet. The shuttle embarked on its
final voyage into space on February 24.Â It is the first of
three U.S. shuttles to be retired this year. Endeavour is set to
take off on its final mission April 19, followed by space
shuttle Atlantis on June 28.Â Discovery’s mission will last 12
days, with a second spacewalk planed for Wednesday. The first
spacewalk was completed on Monday after installing preparations
for the addition of a permanent storage module. Image Caption:
