SpaceX Dragon
From Wikipedia, the free encyclopedia
The SpaceX Dragon is a proposed conventional blunt-cone ballistic capsule spacecraft, capable of carrying seven people or a mixture of personnel and cargo, to and from low Earth orbit. The nosecone of the vehicle has a hinged cap which opens to reveal a standard ISS Common Berthing Mechanism, which allows the Dragon to dock to the US segment of the ISS. The capsule is being developed by SpaceX, a space transportation startup company.
The Dragon capsule will be launched atop a Falcon 9[1] vehicle. SpaceX has built a full-sized prototype of the vehicle and "thoroughly tested" its life support system. SpaceX CEO Elon Musk has stated that he plans to have the capsule enter service by 2009.

[edit] NASA launch partnership
Dragon is part of a proposal submitted on March 3, 2006 for NASA's Commercial Orbital Transportation Services program for commercially delivering cargo and crew to the International Space Station. SpaceX's team for the COTS proposal consists of a number of companies, including MD Robotics, a Canadian company which built the International Space Station's Mobile Servicing System, a robotic arm with a mobile re-attachable base. They intend to use the robotic arm to simplify docking with the space station, thus avoiding the added weight, extra cost and complexity of an on-board docking system such as APAS-89 or the LIDS.
On August 18, 2006, NASA announced that SpaceX has been chosen, along with Kistler Aerospace, to develop crew and cargo launch services for the International Space Station. The plan using SpaceX's Dragon capsule calls for demonstration flights between 2008 and 2010. SpaceX may receive up to $278 million if they meet all NASA milestones.[4][5][6]
[edit] Development
As of December 2007[7], development of the Merlin 1C which would power the Falcon 9 have been completed and is currently undergoing qualifications. Testing firings of Falcon 9's first stage have been conducted.
The Critical Design Review for the Dragon have been completed and approved by NASA. Development of mockups for aerodynamic modelling, ergonomics have been completed. Development and testing on the Dragon heat shield have started.
