And she's off. Here's video of Space Shuttle Atlantis taking off on the final mission for the iconic spacecraft. Atlantis lifted off from Cape Canaveral, Fla., about two hours ago carrying four astronauts on a 12-day mission to deliver a year's worth of supplies to the international space station and haul as much trash as possible back to Earth. This last mission comes 30 years after the first shuttle launch. After this flight, it's anyone's guess as to when the U.S. will field another manned spacecraft despite plans for private companies to deliver American astronauts to space later in this decade. Until that happens, we'll rely on cheap but proven Russian Soyuz capsules to get our astronauts to the International Space Station.
