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.
