Dragon 2 is a class of partially reusable spacecraft developed, manufactured, and operated by American space company SpaceX for flights to the International Space Station (ISS) and private spaceflight missions. The spacecraft, which consists of a reusable space capsule and an expendable trunk module, has two variants: the 4-person Crew Dragon and Cargo Dragon, a replacement for the Dragon 1 cargo capsule. The spacecraft launches atop a Falcon 9 Block 5 rocket, and the capsule returns to Earth through splashdown. Since 2020, when Dragon 2 flew its first crewed and uncrewed flights, it has proven to be the most cost-effective spacecraft ever used by NASA.[11]
Crew Dragon's primary role is to transport crews to and from the ISS under NASA's Commercial Crew Program, a task which was handled by the Space Shuttle until it was retired in 2011. It will be joined by Boeing's Starliner in this role when NASA certifies it. Crew Dragon is also used for commercial flights to ISS and other destinations, and is expected to be used to transport people to and from Axiom Space's planned space station.
Cargo Dragon brings cargo to the ISS under a Commercial Resupply Services-2 contract with NASA, a duty it shares with Northrop Grumman's Cygnus spacecraft. As of July 2024, it is the only reusable orbital cargo spacecraft in operation, though it may eventually be joined by Sierra Nevada Corporation's under-development Dream Chaser spaceplane.[12]
