Space Shuttle Endeavour At International Space Station

The launch was once again postponed until April 29, 2011, in order to avoid a scheduling conflict with a Russian supply vehicle heading for the International Space Station.
The launch was finally carried out on May 16, 2011. Shuttle Endeavour's last mission, STS-134, was a successful launch at 8:56 EST.
One final mission, STS-135, has since been added to the schedule, and Atlantis is allocated to fly in July 2011.
NASA offered the three remaining orbiters for museum donation once they are withdrawn from service. After more than twenty organizations submitted proposals to NASA for the display of an orbiter, NASA announced that Enterprise, from the Udvar-Hazy Center, will go to New York's Intrepid Sea, Air and Space Museum. Discovery will go the Steven F. Udvar-Hazy Center of the National Air and Space Museum, Atlantis will remain in the Visitor Complex at Kennedy Space Center, and Endeavour will go to the California Science Center.
