STS-134 space shuttle mission Commander Mark Kelly (left) addresses employees gathered at the foot of the A-2 Test Stand at NASA's John C. Stennis Space Center during a crew visit June 11. Kelly and fellow crew members visited the rocket engine testing facility prior to their mission later this year aboard shuttle Endeavour. The STS-134 mission is the last scheduled mission for NASA's Space Shuttle Program. Space shuttle Endeavour's STS-134 mission to the International Space Station will deliver the Alpha Magnetic Spectrometer, an instrument designed to measure cosmic rays to help researchers study the formation of the universe. All six members of the STS-134 crew joined Kelly during the visit to Stennis (l to r): Kelly, Mission Specialist Mike Fincke, Pilot Greg Johnson, Mission Specialist Greg Chamitoff, European Space Agency Mission Specialist Roberto Vittori and Mission Specialist Andrew Feustel. During their visit, crew members toured the A-2 Test Stand, where the last scheduled space shuttle main engine test at Stennis was conducted on July 29, 2009. Stennis has tested all of the main engines used on the space shuttle missions, including the ones to be used on the STS-134 flight, targeted for launch in November.
