2.1.1 Commercial Orbital Transportation Services.Further SpaceX commercial resupply flights to ISS under the second Commercial Resupply Services (CRS-2) program use the cargo-carrying variant of the SpaceX Dragon 2 spacecraft. This mission was the last mission of SpaceX of the first Commercial Resupply Services (CRS-1) program, and marked the retirement of the Dragon 1 fleet. The last flight of the first version of the Dragon spacecraft (Dragon 1) launched 7 March 2020 (UTC) it was a cargo resupply mission ( CRS-20) to International Space Station (ISS). The first flight of astronauts on Dragon 2 occurred on the Crew Dragon Demo-2 mission in May 2020. Flight testing was completed in 2019, after a delay caused by a test pad anomaly in April 2019, which resulted in the loss of a Dragon 2 capsule. SpaceX developed a second version called Dragon 2, which is capable of transporting humans. On 3 June 2017, the C106 capsule, largely assembled from previously flown components from the CRS-4 mission in September 2014, was launched again for the first time on CRS-11, with the hull, structural elements, thrusters, harnesses, propellant tanks, plumbing and many of the avionics reused, while the heat shield, batteries and components exposed to sea water upon splashdown for recovery were replaced. With the Dragon spacecraft and the Orbital ATK Cygnus, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry. SpaceX is contracted to deliver cargo to the ISS under NASA's Commercial Resupply Services program, and Dragon began regular cargo flights in October 2012. On, a cargo variant of Dragon became the first commercial spacecraft to successfully rendezvous with and attach to the ISS. Dragon was launched into orbit by the company's Falcon 9 launch vehicle to resupply the International Space Station (ISS).ĭuring its maiden flight in December 2010, Dragon became the first commercially built and operated spacecraft to be recovered successfully from orbit. The SpaceX Dragon, also known as Dragon 1 or Cargo Dragon, was a class of partially reusable cargo spacecraft developed by SpaceX, an American private space transportation company.
