Space shuttle Atlantis lifted off this morning, beginning the last mission of the shuttle program. The program began when space shuttle Columbia flew into space in 1981, and Atlantis flew its first mission in 1985. To mark the final flight, Atlantis crew members are planning to take a flag from the first 1981 shuttle mission to the International Space Station, where it will stay until the first commercial flight to the station. The astronauts will also be taking an iPhone, marking the first time the iPhone has traveled into space.
