At right is Timothy Hughes, senior vice president and general counsel for SpaceX. On Feb. 18, a Falcon 9 rocket with a Dragon spacecraft atop is scheduled to lift off from the launch pad for the SpaceX CRS-10 mission. The historic site is where American astronauts first launched to the moon and was last used in 2011 for the final mission of the Space Shuttle Program. In April 2014, NASA officials signed a 20-year property agreement with SpaceX for use and operation of the launch pad for their Falcon 9 and Falcon 9 Heavy rockets. The SpaceX CRS-10 liftoff is another milestone further establishing Kennedy as a premier, multi-user spaceport. The Dragon spacecraft will deliver 5,000 pounds of supplies and research materials to the space station.

In April 2014, NASA officials signed a 20-year property agreement with SpaceX for use and operation of the launch pad for their Falcon 9 and Falcon 9 Heavy rockets. The SpaceX CRS-10 liftoff is another milestone further establishing Kennedy as a premier, multi-user spaceport. The Dragon spacecraft will deliver 5,000 pounds of supplies and research materials to the space station.

ISS033-E-011170 (10 Oct. 2012) --- The SpaceX Dragon commercial cargo craft is berthed to the Earth-facing side of the International Space Station's Harmony node. Working from the robotics workstation inside the seven-windowed Cupola, Japan Aerospace Exploration Agency astronaut Aki Hoshide, Expedition 33 flight engineer, with the assistance of NASA astronaut Sunita Williams, commander, captured Dragon at 6:56 a.m. (EDT) and used the Canadarm2 robotic arm to berth Dragon to Harmony Oct. 10, 2012. Dragon is scheduled to spend 18 days attached to the station. During that time, the crew will unload 882 pounds of crew supplies, science research and hardware from the cargo craft and reload it with 1,673 pounds of cargo for return to Earth. After Dragon?s mission at the station is completed, the crew will use Canadarm2 to detach Dragon from Harmony and release it for a splashdown about six hours later in the Pacific Ocean, 250 miles off the coast of southern California. Dragon launched atop a Falcon 9 rocket at 8:35 p.m. Oct. 7 from Cape Canaveral Air Force Station in Florida, beginning NASA's first contracted cargo delivery flight, designated SpaceX CRS-1, to the station.
