67-531: Crew Dragon Demo-1 (officially Crew Demo-1 , SpaceX Demo-1 , or Demonstration Mission-1 ) was the first orbital test of the Dragon 2 spacecraft. The mission launched on 2 March 2019 at 07:49:03 UTC , and arrived at the International Space Station on 3 March 2019, a little over 24 hours after the launch. The mission ended with a splashdown on 8 March 2019 at 13:45:08   UTC. During

134-492: A FCC filing by SpaceX for Dragon 2 capsule telemetry, tracking, and command. Demo-1 passed its Flight Readiness Review (FRR) and Launch Readiness Review (LRR) on 22 February 2019 and 27 February 2019 respectively. The Falcon 9 with Demo-1 rolled out to the LC-39A on 28 February 2019 at around 15:00   UTC and went vertical a few hours later. The spacecraft was launched on 2 March 2019 at 07:49:03   UTC and docked with

201-508: A "super high tech zero-g indicator" ( a plush toy ). The "zero-g indicator" was left on board the ISS after undocking, while Ripley returned safely to Earth on 8 March 2019. SpaceX Dragon 2 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

268-458: A Block 4 rocket, completing the transition to an all-Block 5 fleet. The Block 5 design changes are principally driven by upgrades needed for NASA's Commercial Crew program and National Security Space Launch requirements. They include performance upgrades, manufacturing improvements, and increase the margin for demanding customers. In April 2017, SpaceX CEO Elon Musk said that Block 5 will feature 7–8% more thrust by uprating

335-505: 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

402-466: 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

469-493: A Falcon mission-extension kit to the standard second stage, which equipped the second stage with a dark-painted band (for thermal control), extra COPVs for pressurization control, and additional TEA-TEB ignition fluid. The upgrades afforded the second stage with the endurance needed to inject the payloads directly into geosynchronous or high energy orbit where the second stage needs hours after launch. Based on mission requirements, they are Medium Coast & Long Coast kits, i.e.,

536-647: 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, a test dummy was fitted with the spacesuit and sensors. The spacesuit is made from Nomex , a fire-retardant fabric similar to Kevlar . The spacecraft's design was unveiled on 29 May 2014, during a press event at SpaceX headquarters in Hawthorne, California . In October 2014, NASA selected

603-429: 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

670-484: 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

737-406: A duty it shares with Northrop Grumman 's Cygnus spacecraft. As of November 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. There are two variants of Dragon 2: Crew Dragon and Cargo Dragon. Crew Dragon was initially called "DragonRider" and it was intended from

804-488: 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

871-422: 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

938-529: A new expendable trunk for each flight. SpaceX's CCtCap contract values each seat on 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

1005-525: A reality after 2014, when NASA sought bids on a second round of multi-year contracts to bring cargo to the ISS in 2020 through 2024. In January 2016, SpaceX won contracts for six of these flights, dubbed CRS-2 . As of April 2024 , Cargo Dragon has completed nine missions to and from the ISS with six more planned. Cargo Dragons lack several features of the crewed variant, including seats, cockpit controls, astronaut life support systems, and SuperDraco abort engines. Cargo Dragon improves on many aspects of

1072-484: A remote area of the southern Pacific Ocean. The vehicle will attach to the ISS using one of the Cargo Dragon vehicles, which will be paired with a longer trunk module equipped with 46 Draco thrusters (instead of the normal 16) and will carry 30,000 kg (66,000 lb) of propellant, nearly six times the normal load. NASA plans to launch the deorbit vehicle in 2030 where it will remain attached, dormant, for about

1139-401: 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 . Crew Dragon's primary role is to transport crews to and from the ISS under NASA's Commercial Crew Program ,

1206-432: A separate test, on 20 April 2019, the capsule used on Crew Demo-1 was unexpectedly destroyed when firing the SuperDraco engines at Landing Zone 1. The spacecraft tested the approach and automated docking procedures with the International Space Station (ISS), consequent undocking from the ISS, full re-entry , splashdown and recovery steps to provide data requisite to subsequently qualify for flights transporting humans to

1273-495: A separation and abort scenario in the troposphere at transonic velocities shortly after passing through max Q , where the vehicle experiences maximum aerodynamic pressure. The Dragon 2 used its SuperDraco abort engines to push itself away from the Falcon 9 after an intentional premature engine cutoff, after which the Falcon was destroyed by aerodynamic forces. The Dragon followed its suborbital trajectory to apogee, at which point

1340-431: A task 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 ,

1407-483: A year as the station's orbit naturally decays to 220 km (140 mi). The spacecraft is to then conduct one or more orientation burns to lower the perigee to 150 km (93 mi), followed by a final deorbiting burn. In June 2024, NASA awarded a contract worth up to $ 843 million to SpaceX to build the deorbit vehicle as it works to secure funding. SpaceX, which aims to dramatically lower space transportation costs, designed Dragon 2 to be reused, not discarded as

1474-448: Is typical of spacecraft. It is composed of a reusable capsule and a disposable trunk. SpaceX and NASA initially certified the capsule to be used for five missions. As of March 2024 , they are working to certify it for up to fifteen missions. To maximize cost-effectiveness, SpaceX incorporated several innovative design choices. The Crew Dragon employs eight side-mounted SuperDraco engines for its emergency escape system, eliminating

1541-468: The original Dragon design, including the recovery and refurbishment process. Since 2021, Cargo Dragon has been able to provide power to some payloads, saving space in the ISS and eliminating the time needed to move the payloads and set them up inside. This feature, announced on 29 August 2021 during the CRS-23 launch, is called Extend-the-Lab. "For CRS-23 there are 3 Extend-the-Lab payloads launching with

1608-466: The 2010s specified seven flights of any launch vehicle without major design changes before the vehicle would be NASA-certified for human spaceflight , and allowed to fly NASA astronauts. The Block 5 design launched astronauts for the first time on May 30, 2020, on a NASA-contracted flight, Crew Dragon Demo-2 . This was the first crewed orbital spaceflight launched from the United States since

1675-485: The Crew Dragon, above the two center seats (occupied by the commander and pilot), there is a three-screen control panel. Below the seats is the cargo pallet, where around 230 kilograms (500 lb) of items can be stowed. The capsule’s ceiling includes a small space toilet (with privacy curtain), and an International Docking System Standard (IDSS) port. For private spaceflight missions not requiring ISS docking,

1742-674: The Crew Dragon. The spacecraft can be operated in full vacuum , and "the crew will wear SpaceX-designed space suits to protect them from a rapid cabin depressurization emergency event". The spacecraft has also been designed to be able to land safely with a leak "of up to an equivalent orifice of 6.35 mm [0.25 in] in diameter". The spacecraft's nose cone protects the docking port and four forward-facing thrusters during ascent and reentry. This component pivots open for in-space operations. Dragon 2's propellant and helium pressurant for emergency abort and orbital maneuvers are stored in composite-carbon-overwrap titanium spherical tanks at

1809-600: The Dragon spacecraft as one of the candidates to fly American astronauts to the International Space Station, under the Commercial Crew Program . In March 2022, SpaceX President Gwynne Shotwell told Reuters that "We are finishing our final (capsule), but we still are manufacturing components, because we'll be refurbishing". SpaceX later decided to build a fifth Crew Dragon capsule, to be available by 2024. SpaceX also manufactures

1876-404: The Falcon 9 is not reused. This variant sacrifices 10% thrust in exchange for a 75% reduction in material usage, primarily the rare metal niobium . As a result, SpaceX can triple its launch frequency using the same amount of this critical resource. Due to its reduced performance, this nozzle is exclusively used on missions with lower performance requirements. The NASA certification processes of

1943-517: The IDSS port can be replaced with a 1.2-meter (3 ft 11 in) domed plexiglass window offering panoramic views, similar to the ISS Cupola . Additionally, SpaceX has developed a "Skywalker" hatch for missions involving extravehicular activities . The Cargo Dragon is also loaded from the side hatch and has an IDSS port on the ceiling. However, it lacks the control panels, windows, and seats of

2010-533: The ISS for a nominal period of 180 days, but is designed to remain on the station for up to 210 days, matching the Russian Soyuz spacecraft . Crew Dragon includes an integrated pusher launch escape system whose eight SuperDraco engines can pull 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

2077-556: The ISS on 3 March 2019 at 10:51   UTC. The Dragon 2 spacecraft undocked from the ISS on 8 March 2019 at 07:32   UTC. The capsule separated from the trunk, performed its de-orbit burn, entered the Earth's atmosphere and splashed down in the Atlantic Ocean about 320 km (200 mi) off Florida's east coast later that day at 13:45:08   UTC. The capsule was recovered using SpaceX's recovery ship GO Searcher and

2144-417: The ISS. Life support systems were monitored throughout the test flight. The capsule was to be re-used in an in-flight abort test , but it was destroyed in an accident during a static fire test of its SuperDraco thrusters. The mission was launched on a SpaceX Falcon 9 Block 5 launch vehicle contracted by NASA's Commercial Crew Program . Initial plans had hoped to see CCDev2 flights as early as 2015. Demo-1

2211-608: The ISS. SpaceX was to receive up to US$ 2.6 billion under this contract to provide development test flights and up to six operational flights. Dragon was the less expensive proposal, but NASA's William H. Gerstenmaier considered the Boeing Starliner proposal the stronger of the two. However, Crew Dragon's first operational flight, SpaceX Crew-1 , was on 16 November 2020 after several test flights, while Starliner suffered multiple problems and delays, with its first operational flight slipping to no earlier than early 2025. In

2278-560: The United States by SpaceX . It is the fifth major version of the Falcon 9 family and the third version of the Falcon 9 Full Thrust . It is powered by Merlin 1D engines burning rocket-grade kerosene ( RP-1 ) and liquid oxygen (LOX). The main changes from Block 3 (the original Falcon 9 Full Thrust) to Block 5 are higher-thrust engines and improvements to the landing legs along with numerous other small changes to streamline recovery and re-use of first-stage boosters and increase

2345-512: The beginning to support a crew of seven or a combination of crew and cargo. Earlier spacecraft had a berthing port and were berthed to ISS by ISS personnel. Dragon 2 instead has an IDSS -compatible docking port to dock to the International Docking Adapter ports on ISS. It is able to perform fully autonomous rendezvous and docking with manual override ability. For typical missions, Crew Dragon will remain docked to

2412-431: 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,

2479-412: The capsule's base in an area known as the service section. For launch aborts, the capsule relies on eight SuperDraco engines arranged in four redundant pairs. Each engine generates 71 kN (16,000 lb f ) of thrust. Sixteen smaller Draco thrusters placed around the spacecraft control its attitude and perform orbital maneuvers. When the capsule returns to Earth, a PICA-3 heat shield safeguards

2546-442: 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 was later cancelled, leaving ocean splashdown under parachutes as the only option. In 2012, SpaceX was in talks with Orbital Outfitters about developing space suits to wear during launch and re-entry. Each crew member wears

2613-464: The engines (from 176,000 pounds-force (780,000 N) to 190,000 pounds-force (850,000 N) per engine). Block 5 includes an improved flight control system for an optimized angle of attack on the descent, lowering landing fuel requirements. For reusability endurance: For rapid reusability: Since the debut of Block 5, SpaceX has continued to iterate on its design, manufacturing processes, and operational procedures. Among other changes,

2680-530: The entirety the test flight. The same capsule was planned to be re-used in June 2019 for an in-flight abort test before it exploded on 20 April 2019. On 20 April 2019, Crew Dragon  C204 , the capsule used in the Demo-1 mission, was destroyed in an explosion during static fire testing at the Landing Zone 1 facility. On the day of the explosion, the initial testing of the Crew Dragon's Draco thrusters

2747-425: The final Space Shuttle mission, STS-135 . The first orbital test of Crew Dragon was an uncrewed mission, commonly called "Demo-1" and launched on 2 March 2019. The spacecraft tested the approach and automated docking procedures with the ISS, remained docked until 8 March 2019, then conducted the full re-entry, splashdown and recovery steps to qualify for a crewed mission. Life-support systems were monitored for

Crew Dragon Demo-1 - Misplaced Pages Continue

2814-450: The first crewed Crew Dragon Demo-2 to the International Space Station would launch on 27 May 2020. Astronauts Bob Behnken and Doug Hurley crewed the mission, marking the first crewed launch to the International Space Station from U.S. soil since STS-135 in July 2011. The original launch was postponed to 30 May 2020 due to weather conditions at the launch site. The second launch attempt

2881-499: The first crewed flight launched on 30 May 2020 with the launch of the Demo-2 mission. In June 2019, Bigelow Aerospace announced it had reserved with SpaceX up to four missions of four passengers each to the ISS as early as 2020 and planned to sell them for around US$ 52 million per seat. These plans were cancelled by September 2019. Space Adventures contracted SpaceX for a five-day high elliptic orbit space tourism mission with

2948-630: The initial Block 5 boosters did not have the redesigned composite overwrapped pressure vessel (COPV2) tanks. The first booster with COPV2 tanks was booster B1047 on the Es'hail 2 mission on November 15, 2018, and the second booster using the COPV2 tanks was CRS-16 / B1050 , which had its first launch on December 5, 2018. Later Block 5 boosters are also easier to prepare for flight, so SpaceX "prefer to retire" older cores by assigning them to expendable missions when possible. A pressure relief valve

3015-422: The mission, and once docked, a 4th which is currently already on the space station will be added to Dragon". For the first time, Dragon Cargo Dragon  C208 performed test reboost of the ISS via its aft-facing Draco thrusters on 8 November 2024 at 17:50 UTC. The US Deorbit Vehicle is a planned Cargo Dragon variant that will be used to deorbit the ISS and direct any remnants into the " spacecraft cemetery ",

3082-481: The most challenging atmospheric conditions of the flight trajectory, imposing the worst structural stress of a real flight on the rocket and spacecraft. The abort test was performed using a Falcon 9 Block 5 rocket with a fully fueled second stage with a mass simulator replacing the Merlin engine. Earlier, this test had been scheduled before the uncrewed orbital test, however, SpaceX and NASA considered it safer to use

3149-535: The need for a traditional, disposable escape tower . Furthermore, instead of housing the critical and expensive life support , thruster , and propellant storage systems in a disposable service module , Dragon 2 integrates them within the capsule for reuse. The trunk serves as an adapter between the capsule and the Falcon 9 rocket's second stage and also includes solar panels , a heat-dissipation radiator , and fins to provide aerodynamic stability during emergency aborts. Dragon 2 integrates solar arrays directly into

3216-399: The number of helium bottles for pressurization and added batteries for power and other hardware to make sure that the fuel and stages systems operate as long as needed. The Transporter-7 mission marked the debut of a second stage with a Merlin 1D Vacuum engine with a shorter nozzle extension designed to accelerate production and reduce costs. Unlike the first stage, the second stage on

3283-417: The passengers approximately two hours prior to the scheduled launch; the ground crew will then depart the launch pad and move to a safe distance. The launch escape system will be activated approximately 40 minutes prior to launch, with propellant loading commencing several minutes later. The first automated test mission launched to the International Space Station (ISS) on 2 March 2019. After schedule slips,

3350-477: The production rate. Each Block 5 booster is designed to fly ten times with only minor maintenance between launches and potentially up to 100 times with periodic refurbishment. In 2018, Block 5 succeeded the transitional Block 4 version. The maiden flight of the Block ;5 launched the satellite Bangabandhu-1 on May 11, 2018. The CRS-15 mission on June 29, 2018, was the last to be launched on

3417-480: The spacecraft before it began carrying astronauts to the International Space Station under NASA's Commercial Crew Program. Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams conducted full data reviews that needed to be completed prior to NASA astronauts flying on the system during SpaceX's Demo-2 mission. On 17 April 2020, NASA Administrator Jim Bridenstine announced

3484-541: The spacecraft's trunk was jettisoned. The smaller Draco engines were then used to orient the vehicle for the descent. All major functions were executed, including separation, engine firings, parachute deployment, and landing. Dragon 2 splashed down at 15:38:54 UTC just off the Florida coast in the Atlantic Ocean. The test objective was to demonstrate the ability to safely move away from the ascending rocket under

3551-407: The spacecraft, a pilot who serves as backup for both command and operations and two mission specialists who may have specific duties assigned depending on the mission. However, the Crew Dragon can fly missions with just two astronauts as needed, and in an emergency, up to seven astronauts could return to Earth from the ISS on Dragon. On the ground, crews enter the capsule through a side hatch. On

3618-411: The system 100 ms before firing damaged a check valve and resulted in the explosion. SpaceX modified the Dragon 2 replacing check valves with burst discs , which are designed for single use, and the adding of flaps to each SuperDraco to seal the thrusters prior to splashdown, preventing water intrusion. The SuperDraco engine test was repeated on 13 November 2019 with Crew Dragon  C205 . The test

3685-504: The trunk separation but with the parachutes it was a pretty significant jolt". List includes only completed or currently manifested missions. Dates are listed in UTC , and for future events, they are the earliest possible opportunities (also known as NET dates) and may change. Falcon 9 Block 5 Falcon 9 Block 5 is a partially reusable , human-rated , two-stage-to-orbit , medium-lift launch vehicle designed and manufactured in

3752-483: The trunk's structure, replacing the deployable panels of its predecessor, Dragon 1. The trunk can also accommodate unpressurized cargo, such as the Roll Out Solar Array transported to the ISS. The trunk is connected to the capsule using a fitting known as "the claw." The typical Crew Dragon mission includes four astronauts: a commander who leads the mission and has primary responsibility for operating

3819-544: The use of the SuperDraco thrusters for propulsive landing was enabled again, but only as a back-up for parachute emergencies. Crew Dragon is used by both commercial and government customers. Axiom launches commercial astronauts to the ISS and intends to eventually launch to their own private space station. NASA flights to the ISS have four astronauts, with the added payload mass and volume used to carry pressurized cargo. On 16 September 2014, NASA announced that SpaceX and Boeing had been selected to provide crew transportation to

3886-416: The vehicle. And as the vehicle tries to control, you feel a little bit of that shimmy in your body. ... We could feel those small rolls and pitches and yaws—all those little motions were things we picked up on inside the vehicle. ... All the separation events, from the trunk separation through the parachute firings, were very much like getting hit in the back of the chair with a baseball bat ... pretty light for

3953-615: The way to starting commercial services under an upcoming ISS Crew Transportation Services contract. On 3 August 2018, NASA announced the crew for the DM-2 mission. The crew of two consisted of NASA astronauts Bob Behnken and Doug Hurley . Behnken previously flew as mission specialist on the STS-123 and the STS-130 missions. Hurley previously flew as a pilot on the STS-127 mission and on

4020-529: Was added to the grid fins’ hydraulic system following a stall that resulted in a landing failure in 2018. Similarly, after a booster was damaged at sea in 2022, much of the fleet was upgraded with "self-leveling" landing legs. These legs help ensure the booster can be properly secured to the Octograbber, even in suboptimal sea states. To improve the rocket's performance, SpaceX has tweaked throttle settings and separation timings. SpaceX CRS-18 featured

4087-582: Was detected after the flight in one of the eight SuperDraco engines causing it to under perform, but did not materially affect the flight. On 24 November 2015, SpaceX conducted a test of Dragon 2's hovering abilities at the firm's rocket development facility in McGregor, Texas . In a video, the spacecraft is shown suspended by a hoisting cable and igniting its SuperDraco engines to hover for about 5 seconds, balancing on its 8 engines firing at reduced thrust to compensate exactly for gravity. The test vehicle

4154-476: Was eventually slated for no earlier than December 2016, and then delayed several times throughout 2017. The first exact date was published by NASA in November 2018 to be 17 January 2019, but this was delayed until February 2019. The static fire took place on 24 January 2019 and the launch date was set to 23 February 2019. By the end of January 2019, the launch was delayed to no earlier than 2 March 2019 according to

4221-559: Was returned to the mainland where it was examined and the data collected by the on board sensors was analyzed. Instead of carrying astronauts to the ISS, this flight had an Anthropomorphic Test Device (ATD) wearing SpaceX's custom flight suit . The ATD is named Ripley , as a homage to Sigourney Weaver's character in the Alien movies franchise . The capsule was weighted similarly to missions with astronauts onboard and carried about 180 kg (400 lb) of supplies and equipment including

4288-405: 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

4355-450: 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

4422-464: 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

4489-480: 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
