The spacecraft is named after Space Shuttle Endeavour . It first launched on 30 May 2020 to the International Space Station (ISS) on the Crew Dragon Demo-2 mission. It has subsequently been used for the SpaceX Crew-2 mission that launched in April 2021,
164-479: A 3.5-year effort to upgrade the International Space Station’s power system. At completion, 24 new lithium-ion batteries and adapter plates will replace 48 aging nickel-hydrogen batteries. In April 2019, one of the newly installed lithium-ion batteries on the near port truss blew a fuse, so two nickel-hydrogen batteries were re-installed to take its place. A new replacement lithium-ion battery arrived to
246-442: A Crew Dragon flight to be around US$ 88 million, while the face value of each seat has been estimated by NASA's Office of Inspector General (OIG) to be around US$ 55 million. This contrasts with the 2014 Soyuz launch price of US$ 76 million per seat for NASA astronauts. Dragon 2 was intended from the earliest design concept to carry crew, or with fewer seats, both crew and cargo. The cargo version, dubbed Cargo Dragon , became
328-545: A Crew Dragon in 2022. In October 2021, Space Adventures stated that the contract had expired and would not be executed, but left open the possibility of a partnership with SpaceX in the future. SpaceX planned a series of four flight tests for the Crew Dragon: a pad abort test, an uncrewed orbital flight to the ISS, an in-flight abort test, and finally, a crewed flight to the ISS, which was initially planned for July 2019, but after
410-460: A Dragon capsule explosion, was delayed to May 2020. The pad abort test was conducted successfully on 6 May 2015 at SpaceX's leased SLC-40 launch site. Dragon landed safely in the ocean to the east of the launchpad 99 seconds after ignition of the SuperDraco engines. While a flight-like Dragon 2 and trunk were used for the pad abort test, they rested atop a truss structure for the test rather than
492-478: A departure from the prior NASA practice, where construction contracts with commercial firms led to direct NASA operation of the spacecraft, NASA is purchasing space transport services from SpaceX, including construction, launch, and operation of the Dragon 2. In August 2018, NASA and SpaceX agreed on the loading procedures for propellants , vehicle fluids and crew. High-pressure helium will be loaded first, followed by
574-477: A dragon all the way up ... a little bit less g's [than the Space Shuttle ] but more 'alive' is probably the best way I would describe it". Regarding descent in the spacecraft, Behnken stated, "Once we descended a little bit into the atmosphere, Dragon really came alive. It started to fire thrusters and keep us pointed in the appropriate direction. The atmosphere starts to make noise—you can hear that rumble outside
656-479: A flight representative capsule rather than the test article from the pad abort test. This test was previously planned to use the capsule C204 from Demo-1, however, C204 was destroyed in an explosion during a static fire testing on 20 April 2019. Capsule C205 , originally planned for Demo-2 was used for the In-Flight Abort Test with C206 being planned for use during Demo-2. This was the final flight test of
738-422: A full Falcon 9 rocket. A crash test dummy embedded with a suite of sensors was placed inside the test vehicle to record acceleration loads and forces at the crew seat, while the remaining six seats were loaded with weights to simulate full-passenger-load weight. The test objective was to demonstrate sufficient total impulse , thrust and controllability to conduct a safe pad abort. A fuel mixture ratio issue
820-493: A full production Crew Dragon capable of staying in space for up to 210 days. During the mission, NASA gave SpaceX approval to reuse flight-proven Crew Dragon spacecraft.

2870-423: The capsule away from the launch vehicle in an emergency. SpaceX originally intended to use the SuperDraco engines to land Crew Dragon on land; parachutes and an ocean splashdown were envisioned for use only in the case of an aborted launch. Precision water landing under parachutes was proposed to NASA as "the baseline return and recovery approach for the first few flights" of Crew Dragon. However, propulsive landing
2952-431: The capsule during reentry. Dragon 2 uses a total of six parachutes (two drogues and four mains) to decelerate after atmospheric entry and before splashdown, compared to the five used by Dragon 1. The additional parachute was required by NASA as a safety measure after a Dragon 1 suffered a parachute malfunction. The company also went through two rounds of parachute development before being certified to fly with crew. In 2024,

In 2012, SpaceX was in talks with Orbital Outfitters about developing space suits to wear during launch and re-entry. Each crew member wears a custom-fitted space suit that provides cooling inside inside the Dragon (IVA type suit) but can also protect its wearer in a rapid cabin depressurization . For the Demo-1 mission,
6068-622: Was later used by his wife, K. Megan McArthur on the Crew-2 flight. Endeavour's most recent mission was SpaceX Crew-8 . It launched on 3 March 2024 (local time) and returned to Earth on 25 October 2024. One of the crew members, Mission Specialist Jeanette Epps , became the second African-American woman to be part of a long-duration mission onboard the ISS. The mission spent extra time in space due to an unexpected need to support Boeing Crew Flight Test mission astronauts Sunita Williams and Butch Wilmore after problems with their spacecraft. Weather in
6150-568: Was originally planned to be used for the Crew Dragon In-Flight Abort Test . However, on 20 April 2019, Crew Dragon C204 was destroyed in an explosion during static fire testing at the Landing Zone 1 facility. On the day of the anomaly, the initial testing of the Crew Dragon's Draco thrusters was successful, with the explosion occurring during the test of the SuperDraco abort system. Crew Dragon C205 , then slated to be used for
6232-405: Was successful, showing that the modifications made to the vehicle were successful. Since the destroyed capsule had been slated for use in the upcoming in-flight abort test, the explosion and investigation delayed that test and the subsequent crewed orbital test. The Crew Dragon in-flight abort test was launched on 19 January 2020 at 15:30 UTC from LC-39A on a suborbital trajectory to conduct
6314-450: Was successful, with capsule C206, later named Endeavour by the crew, launching on 30 May 2020 19:22 UTC . The capsule successfully docked with the International Space Station on 31 May 2020 at 14:27 UTC. On 2 August 2020, Crew Dragon undocked and splashed-down successfully in the Atlantic Ocean. Launching in the Dragon 2 spacecraft was described by astronaut Bob Behnken as "smooth off the pad" but "we were definitely driving and riding
6396-406: Was successful, with the anomaly occurring during the test of the SuperDraco abort system. Telemetry, high-speed camera footage, and analysis of recovered debris indicate the problem occurred when a small amount of dinitrogen tetroxide leaked into a helium line used to pressurize the propellant tanks. The leakage apparently occurred during pre-test processing. As a result, the pressurization of
6478-408: Was the 10th spacewalk for each astronaut, tying them with Michael Lopez-Alegria and Peggy Whitson as the only other U.S. astronauts to complete 10 spacewalks. Behnken has now spent a total of 61 hours and 10 minutes spacewalking, which makes him the U.S. astronaut with the third most total time spacewalking, behind Lopez-Alegria and Andrew Feustel , and the fourth most overall. Cassidy now has spent
6560-571: Was the first to carry a crew to the International Space Station from the United States since STS-135 in July 2011. In a video tour of the spacecraft, shortly after the launch, Behnken and Hurley revealed they named the capsule Endeavour after the Space Shuttle Endeavour . They both flew their first space missions on Space Shuttle Endeavour , on missions STS-123 and STS-127 , respectively. Additionally, each crew member brought along
6642-469: Was the same capsule that performed the pad abort test earlier in 2015; it was nicknamed DragonFly . In 2015, NASA named its first Commercial Crew astronaut cadre of four veteran astronauts to work with SpaceX and Boeing – Robert Behnken , Eric Boe , Sunita Williams , and Douglas Hurley . The Demo-1 mission completed the last milestone of the Commercial Crew Development program, paving
6724-595: Was then mated to a Falcon 9 rocket and was rolled out onto the launch pad on 21 May 2020, with a static fire test completed the next day. Astronauts Bob Behnken and Doug Hurley were selected by NASA as the Demo-2 mission crew on 3 August 2018. Their mission validated crewed spaceflight operations using SpaceX hardware, including the Dragon spacecraft, the Falcon 9 rocket. SpaceX scrubbed Demo-2's first launch attempt because of weather conditions. The Demo-2 mission successfully launched on 30 May 2020. Hurley and Behnken's launch
