Crew Dragon Ĭrew Dragon incorporates an integrated pusher launch escape system consisting of eight SuperDraco engines, capable of accelerating the vehicle away from the rocket in an emergency. SpaceX uses the Falcon 9 Block 5 launch vehicle to launch Dragon 2. For typical missions, Crew Dragon will remain docked to the ISS for a nominal period of 180 days, but is designed to remain on the station for up to 210 days, matching the Russian Soyuz spacecraft. It is able to perform fully autonomous rendezvous and docking with manual override ability. Dragon 2 instead has an IDSS-compatible docking port to dock to the International Docking Adapter ports on ISS. Earlier spacecraft had a berthing port and were berthed to ISS by ISS personnel. Crew Dragon was initially called "DragonRider" and it was intended from the beginning to support a crew of seven or a combination of crew and cargo. There are two variants of Dragon 2: Crew Dragon and Cargo Dragon. Crew Dragon is also used for commercial flights, some of them to the ISS, and is expected to be used to shuttle people to and from Axiom Space's planned space station. It will be joined by Boeing Starliner in this role in 2024. Crew Dragon's primary role is to transport crews to and from the ISS under NASA's Commercial Crew Program, succeeding the crew orbital transportation capabilities of the Space Shuttle, which retired from service in 2011.
human-rated orbital transport spacecraft. As of July 2023 it is the only reusable orbital cargo spacecraft in operation.Īs of July 2023, Crew Dragon is the only U.S. It shares this duty with Northrop Grumman Innovation Systems' Cygnus spacecraft, and Sierra Nevada Corporation's Dream Chaser spaceplane is expected to join them in 2023. The first flight of Dragon 2 in a cargo configuration launched in December 2020. The spacecraft launches atop a Falcon 9 Block 5 rocket and the capsule returns to Earth through splashdown.Ĭargo Dragon supplies cargo to the ISS under a Commercial Resupply Services-2 contract with NASA. The spacecraft consists of a reusable space capsule and an expendable trunk module.
There are two variants of the Dragon spacecraft: Crew Dragon, a spacecraft capable of ferrying four crewmembers, and Cargo Dragon, an updated replacement for the original Dragon 1 used to carry freight to and from space. SpaceX also launches private missions, such as Inspiration4 and Axiom Mission 1.
