CAPE CANAVERAL, Fla. - As nine engines ignite under the SpaceX Falcon 9, the rocket springs to life at Space Launch Complex 40 on Cape Canaveral Air Force Station, boosting the Dragon resupply spacecraft on the SpaceX-3 mission to the International Space Station. Launch was at 3:25 p.m. EDT. Dragon is making its fourth trip to the space station. The SpaceX-3 mission, carrying almost 2.5 tons of supplies, technology and science experiments, is the third of 12 flights through a $1.6 billion NASA Commercial Resupply Services contract. Dragon's cargo will support more than 150 experiments that will be conducted during the station's Expeditions 39 and 40.
