Discovery, the world's most traveled spaceship, thundered into orbit for the final time today, heading toward the International Space Station on a journey that marks the beginning of the end of the shuttle era. The six astronauts on board, all experienced space fliers, were thrilled to be on their way after a delay of nearly four months for fuel tank repairs. But it puts Discovery on the cusp of retirement when it returns in 11 days and eventually heads to a museum.
Discovery is the oldest of NASA's three surviving space shuttles and the first to be decommissioned this year. Two missions remain, first by Atlantis and then Endeavour, to end the 30-year program. This was Discovery's 39th launch and the 133rd shuttle mission overall. "Enjoy the ride," the test conductor radioed just before liftoff. Commander Steven Lindsey thanked everyone for the work in getting Discovery ready to go: "And for those watching, get ready to witness the majesty and the power of Discovery as she lifts off one final time."
