The launch will mark Discovery’s 39th journey, and NASA’s 133rd shuttle mission overall. One final space shuttle launch is scheduled for Feb. 27, 2011, before NASA retires the shuttle fleet for good.

Discovery is scheduled to take off at 3:52 pm EDT on Wednesday, Nov. 3, but the Chicago Tribune reports an electrical glitch may push the launch back to Thursday or later.
