Following a detailed, integrated assessment, NASA selected target launch dates for the remaining eight space shuttle missions on the current manifest in 2009 and 2010. The manifest includes one flight to the Hubble Space Telescope, seven assembly flights to the International Space Station, and two station contingency flights, planned to be completed before the end of fiscal year 2010. The agency previously selected Oct. 8 and Nov. 10 as launch dates for Atlantis' STS-125 mission to service Hubble and Endeavour's STS-126 / ULF-2 mission to supply the space station and service both Solar Alpha Rotary Joints on the port and starboard end of its truss backbone that supports equipment and solar arrays.

The approved target dates are subject to change based on processing and other launch vehicle schedules. They reflect the agency's commitment to complete assembly of the station and to retire the shuttle fleet as transition continues to the new launch vehicles, including Ares and Orion.
