Discovery concludes a stellar career

The most-flown aircraft in the history of the world is now going into retirement. Space shuttle Discovery landed safely on Wednesday, ending its 39th and final space mission. Discovery spent a total of 365 in pace while making 5.830 orbits of Earth and flying an astonishing 148 million miles. If flown in a straight line, this distance could have put the spacecraft roughly 50 million miles past the Sun! Discovery first flew in 1984, following only sister shuttles Challenger and Columbia....both of which were destroyed during failed missions. She will now be decommissioned and moved to a museum, likely the Smithsonian.
