NASA announced Thursday that space shuttle Atlantis’ STS-125 mission to repair the Hubble Space Telescope is targeted to launch May 12, 2009.
NASA delayed the final servicing mission to Hubble in September when a data-handling unit on the telescope failed. Since then, engineers are working to prepare a spare unit for flight. They expect to be able to ship the spare, known as the Science Instrument Command and Data Handling System, to NASA’s Kennedy Space Center in Florida in spring 2009.
STS-125 is an 11-day flight featuring five spacewalks to extend Hubble’s life into the next decade by refurbishing and upgrading the telescope with state-of-the-art science instruments and swapping failed hardware.
The manifest has been adjusted to reflect current planning. The next space shuttle mission, STS-119, is targeted for launch February 12, 2009. Preparations continue for the STS-127 mission, currently targeted for launch in May 2009. That launch will be further assessed and coordinated with NASA’s international partners at a later date. STS-128 is targeted for August 2009, and STS-129 is targeted for November 2009. All target launch dates are subject to change.
