SpaceX's Falcon 9 rocket successfully launched from Cape Canaveral, Florida this morning, lofting the company's Dragon cargo capsule into orbit around Earth. Bound for the International Space Station, the Dragon will bring nearly 5,000 pounds of supplies and science experiments for the station's onboard crew. Today's launch marks the ninth cargo resupply mission that SpaceX has done for NASA, and the eighth one to make it to orbit.
