Discovery's launch last week will be followed by the space shuttles Endeavour in April and Atlantis in June. When Atlantis makes its return to earth this summer, it will be the final time a space shuttle will enter earth's atmosphere, as the program is to be dismantled. Discovery's launch has been called "the beginning of the end of the U.S. space-shuttle program" by The Chicago Tribune.
The following images from the final mission were released by NASA.
