Workers lower the Space Exploration Technologies Corp. SpaceX Dragon capsule at Cape Canaveral Air Force Station in Florida.

Workers lower the latest Space Exploration Technologies Corp. (SpaceX) Dragon capsule at Cape Canaveral Air Force Station in Florida on Oct. 23 so it can be processed and attached to the top of a Falcon 9 rocket on Space Launch Complex-40 for the company's next demonstration test flight for NASA's Commercial Orbital Transportation Services (COTS) program.

SpaceX is one of two companies under contract with NASA to take cargo to the International Space Station. NASA is working with SpaceX to combine its last two demonstration flights, and if approved, the Falcon 9 rocket would launch the Dragon capsule to the orbiting laboratory for a docking within the next several months.
