The spacecraft's design was unveiled on 29 May 2014, during a press event at SpaceX headquarters in Hawthorne, California . In October 2014, NASA selected
657-429: A departure from the prior NASA practice, where construction contracts with commercial firms led to direct NASA operation of the spacecraft, NASA is purchasing space transport services from SpaceX, including construction, launch, and operation of the Dragon 2. In August 2018, NASA and SpaceX agreed on the loading procedures for propellants , vehicle fluids and crew. High-pressure helium will be loaded first, followed by
730-422: A dragon all the way up ... a little bit less g's [than the Space Shuttle ] but more 'alive' is probably the best way I would describe it". Regarding descent in the spacecraft, Behnken stated, "Once we descended a little bit into the atmosphere, Dragon really came alive. It started to fire thrusters and keep us pointed in the appropriate direction. The atmosphere starts to make noise—you can hear that rumble outside
803-488: A flight representative capsule rather than the test article from the pad abort test. This test was previously planned to use the capsule C204 from Demo-1, however, C204 was destroyed in an explosion during a static fire testing on 20 April 2019. Capsule C205 , originally planned for Demo-2 was used for the In-Flight Abort Test with C206 being planned for use during Demo-2. This was the final flight test of

Some of the reviews that may be done on an effort include: The MCR affirms the mission need and examines the proposed mission's objectives and the concept for meeting those objectives. The SRR examines
1022-529: A new expendable trunk for each flight. SpaceX's CCtCap contract values each seat on a Crew Dragon flight to be around US$ 88 million, while the face value of each seat has been estimated by NASA's Office of Inspector General (OIG) to be around US$ 55 million. This contrasts with the 2014 Soyuz launch price of US$ 76 million per seat for NASA astronauts. Dragon 2 was intended from the earliest design concept to carry crew, or with fewer seats, both crew and cargo. The cargo version, dubbed Cargo Dragon , became
1095-525: A reality after 2014, when NASA sought bids on a second round of multi-year contracts to bring cargo to the ISS in 2020 through 2024. In January 2016, SpaceX won contracts for six of these flights, dubbed CRS-2 . As of April 2024 , Cargo Dragon has completed nine missions to and from the ISS with six more planned. Cargo Dragons lack several features of the crewed variant, including seats, cockpit controls, astronaut life support systems, and SuperDraco abort engines. Cargo Dragon improves on many aspects of
1168-484: A remote area of the southern Pacific Ocean. The vehicle will attach to the ISS using one of the Cargo Dragon vehicles, which will be paired with a longer trunk module equipped with 46 Draco thrusters (instead of the normal 16) and will carry 30,000 kg (66,000 lb) of propellant, nearly six times the normal load. NASA plans to launch the deorbit vehicle in 2030 where it will remain attached, dormant, for about
1241-495: A separation and abort scenario in the troposphere at transonic velocities shortly after passing through max Q , where the vehicle experiences maximum aerodynamic pressure. The Dragon 2 used its SuperDraco abort engines to push itself away from the Falcon 9 after an intentional premature engine cutoff, after which the Falcon was destroyed by aerodynamic forces. The Dragon followed its suborbital trajectory to apogee, at which point

Crew Dragon includes an integrated pusher launch escape system whose eight SuperDraco engines can pull the capsule away from the launch vehicle in an emergency. SpaceX originally intended to use the SuperDraco engines to land Crew Dragon on land; parachutes and an ocean splashdown were envisioned for use only in
2774-608: The ISS. SpaceX was to receive up to US$ 2.6 billion under this contract to provide development test flights and up to six operational flights. Dragon was the less expensive proposal, but NASA's William H. Gerstenmaier considered the Boeing Starliner proposal the stronger of the two. However, Crew Dragon's first operational flight, SpaceX Crew-1 , was on 16 November 2020 after several test flights, while Starliner suffered multiple problems and delays, with its first operational flight slipping to no earlier than early 2025. In
2847-431: The capsule during reentry. Dragon 2 uses a total of six parachutes (two drogues and four mains) to decelerate after atmospheric entry and before splashdown, compared to the five used by Dragon 1. The additional parachute was required by NASA as a safety measure after a Dragon 1 suffered a parachute malfunction. The company also went through two rounds of parachute development before being certified to fly with crew. In 2024,
2920-412: The capsule's base in an area known as the service section. For launch aborts, the capsule relies on eight SuperDraco engines arranged in four redundant pairs. Each engine generates 71 kN (16,000 lb f ) of thrust. Sixteen smaller Draco thrusters placed around the spacecraft control its attitude and perform orbital maneuvers. When the capsule returns to Earth, a PICA-3 heat shield safeguards
2993-442: The case of an aborted launch. Precision water landing under parachutes was proposed to NASA as "the baseline return and recovery approach for the first few flights" of Crew Dragon. However, propulsive landing was later cancelled, leaving ocean splashdown under parachutes as the only option. In 2012, SpaceX was in talks with Orbital Outfitters about developing space suits to wear during launch and re-entry. Each crew member wears
