NASA set the official expiration date on its aging space shuttle program. The Endeavour will blast off from the Kennedy Space Center on May 31, 2010. When it touches down, the entire fleet will hit retirement.
But before the moth balls come out, NASA will show off its new line of space craft – the Ares. The space agency hopes to test drive these next-gen ships by April 2009.
In the meantime, there are still several important missions left: Hubble telescope repairs in October, space station addition all next year, etc. The BBC pulled together a play-by-play schedule of the 10 remaining missions, so you can count down to the end of the shuttle program and into the age of Ares.
Also, save up your vacation days and plan a trip to Cape Canaveral. You only have 10 more chances to watch these shuttles light up the sky.
