The NASA managers have decided that they would launch the space shuttle called as Discovery on March 11, 2009 to the international space station. The news came after the inspection of the hydrogen flow control valves. The launch date has been one day earlier than the date that was prescribed earlier. However the final say is expected to come up after the review of the flight on Friday. However the managers have felt quite confident enough that they can take away the launch after the final analysis and testing. The liftoff time would be at 9.20 P.M on Wednesday. However it is important to note the fact that the NASA must launch the Discovery by March 13 so that it would stick on to its plan of ten day stay at the station and then return on March 26 on completion of its 72 hour journey, otherwise the shuttle will have to be postponed till April 7. There are seven astronauts who are intending to take up the mission of Discovery and haul the fourth and the final set of the American solar wings to the International Space Station.
