SpaceX, a privately funded company, launched its Falcon 9 rocket in a test flight on May 22, 2012. The rocket's prime cargo, a capsule called Dragon, was filled with food, clothes and supplies for the astronauts and cosmonauts living aboard the International Space Station. The Dragon returned to Earth on May 31, capping off its historic mission with a splashdown in the Pacific Ocean.
On October 10, Dragon successfully delivered a half-ton of supplies to the International Space Station as the first official shipment under a billion-dollar contract with NASA. The contract calls for 12 such shipments. - AP, msnbc, Reuters
