NASA technicians are preparing space shuttle Endeavour for its upcoming launch attempt on Monday, May 16 from Kennedy Space Center's Launch Pad 39A in Florida. Shuttle Weather Officer Kathy Winters has forecasted a 70 percent chance of having favorable weather for Endeavour's liftoff scheduled for 8:56 am Monday.

The six astronauts arrived at the Kennedy's Shuttle Landing Facility in a shuttle training aircraft at 9 am EDT on May 12 for their prelaunch preparations. The crew members for space shuttle Endeavour's STS-134 mission are Commander Mark Kelly, Pilot Gregory Johnson and Mission Specialists Michael Fincke, Greg Chamitoff, Andrew Feustel and European Space Agency astronaut Roberto Vittori.

Endeavour and its crew, during the 16-day mission, will deliver the Alpha Magnetic Spectrometer (AMS) and spare parts including two S-band communications antennas, a high-pressure gas tank and additional spare parts for Dextre.

It's great to be back. We really appreciate all the hard work by the team that's worked over the last couple of weeks to get shuttle Endeavour ready, Commander Mark Kelly said during the press briefing.

Kelly introduced Endeavour's pilot Greg Johnson who commented, I can't think of a more perfect way to spend my birthday then to come here with my crew a get ready to fly Endeavour next week.

We get a lot of attention as the crew, but the real heroes are the folks here at KSC who've been supporting the space shuttle. And hats off to Dana Hutcherson and her team for preparing Endeavour for this flow and finally a special thanks to the APU team for all the hard work you've done getting us to this point. Kudos for solving it and getting us back on track, said Johnson.

Mission Specialists Mike Fincke, Andrew Feustel, Greg Chamitoff and Roberto Vittori, European Space Agency astronaut, Vittori in his native Italian language, each had an opportunity to speak a few words before departing the shuttle runway.
