Uncrewed test flight. DM-1 launched on 2 March 2019 and docked to ISS PMA-2/IDA-2 docking port a little under 24 hours after launch. The Dragon spent five days docked to ISS before undocking and landing on 8 March 2019.
Uncrewed test flight. Was the first flight of an Atlas V with a dual engine Centaur upper stage. Was originally planned to spend eight days docked to ISS before landing. However, Starliner was unable to rendezvous with the station due to the MET anomaly forcing it to enter a lower-than-expected orbit.[5] The spacecraft returned on 22 December 2019 after spending two days in orbit. OFT-2 was proposed to meet all objectives.
A Falcon 9 booster launched a Dragon 2 capsule from LC-39A to perform an in-flight abort shortly after Max q in order to test Dragon 2's launch abort system. Abort occurred at 84 seconds after launch and Dragon 2 successfully separated from the Falcon 9 and flew away using its SuperDraco thrusters. The Falcon 9 booster disintegrated as a result of aerodynamic forces. Dragon 2 splashed down nine minutes after launch after successfully deploying its four parachutes.
Crewed test flight. Dragon 2 launched with two crew members and dock to the ISS about 18 hours later. Dragon and its crew spent up to 62 days on board the ISS.[7]
Uncrewed test flight. Suggested by Boeing and approved by NASA on July 30,2021 at 2:53 p.m. EDT due to the partial failure of software on the previous Starliner test flight, in particular its failure to reach or dock with the ISS.
