Dragon C2 - C15

Dragon [SpaceX]

Dragon is a space capsule designed by SpaceX to provide supplies to the International space station.

The Dragon spacecraft is made up of a pressurized capsule and unpressurized trunk used for Earth to LEO transport of pressurized cargo, unpressurized cargo, and/or crew members. Initiated internally by SpaceX in 2005, Dragon will be utilized to fulfill our NASA COTS contract for demonstration of cargo re-supply of the ISS.

The Dragon capsule is comprised of 3 main elements: the Nosecone, which protects the vessel and the docking adaptor during ascent; the Pressurized Section, which houses the crew and/or pressurized cargo; and the Service Section, which contains avionics, the RCS system, parachutes, and other support infrastructure. In addition an unpressurized trunk is included, which provides for the stowage of unpressurized cargo and will support Dragon's solar arrays and thermal radiators.

SpaceX was one of two winners of the NASA Commercial Orbital Transportation Services competition. The SpaceX portion of the award is $278 million for three flight demonstrations of Falcon-9 carrying the Dragon spaceship, which are scheduled to occur in mid 2009 and 2010. The prototype Dragon C1 capsule lacks several systems of the operational Dragon-C capusle. The final flight will culminate in the transfer of cargo to the International Space Station (ISS) and return of cargo safely to Earth.

The agreement also contains an option for three demonstration flights of the seven person manned version of Dragon taking people to the ISS and back. The cargo Dragon and crewed Dragon are almost identical, with the exception of the crew escape system, the life support system and onboard controls that allow the crew to take over control from the flight computer when needed.

In addition to servicing NASA needs, the F9/Dragon will possibly also be of service to Bigelow Aerospace, which plans to orbit a commercial space station. Bigelow Aerospace and SpaceX have an ongoing dialogue to ensure that F9/Dragon meets the human transportation needs of their planned space station as efficiently as possible.

In December 2008 SpaceX received a contract to deliver 20.000 kg to the ISS by the means of 12 Dragon flights.
