A Falcon 9 rocket with a Dragon capsule secured atop rolls into position between the lightning masts on the pad at Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida. Preparations are under way to lift the rocket into a vertical position for launch.

Space Exploration Technologies Corp., or SpaceX, built both the rocket and capsule for NASA's first Commercial Resupply Services, or CRS-1, mission to the International Space Station. Rollout was complete at 9:55 p.m. EDT. SpaceX CRS-1 is an important step toward making America’s microgravity research program self-sufficient by providing a way to deliver and return significant amounts of cargo, including science experiments, to and from the orbiting laboratory. Launch is scheduled for 8:35 p.m. EDT on Oct. 7. NASA has contracted for 12 commercial resupply flights from SpaceX and eight from the Orbital Sciences Corp.
