Dragon 2 is a class of partially reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX, primarily for flights to the International Space Station (ISS). SpaceX has also launched private missions such as Inspiration4 and Axiom Mission 1. There are two variants: Crew Dragon, a spacecraft capable of ferrying four crew, and Cargo Dragon, an updated replacement for the original Dragon 1. The spacecraft consists of a reuseable space capsule and an expendable trunk module. The spacecraft launches atop a Falcon 9 Block 5 rocket and the capsule returns to Earth via splashdown. Cargo Dragon supplies cargo to the ISS under a Commercial Resupply Services-2 contract with NASA. The first flight of Dragon 2 in a cargo configuration launched in December 2020. It shares this duty with Northrop Grumman Innovation Systems' Cygnus spacecraft, and Sierra Nevada Corporation's Dream Chaser spacecraft is expected to join them in 2023. As of January 2023, Crew Dragon is the only U.S. human-rated orbital transport spacecraft, the only reusable orbital crewed spacecraft and the only reusable orbital cargo spacecraft currently in operation. Its 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. It will be joined by Boeing Starliner in this role some time in 2023. 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.
