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. There are two variants of the Dragon spacecraft: Crew Dragon, capable of ferrying four crewmembers, and Cargo Dragon, a replacement for the original Dragon 1 used to carry freight to and from space. The spacecraft consists of a reusable space capsule and an expendable trunk module. The spacecraft launches atop a Falcon 9 Block 5 rocket and the capsule returns to Earth through splashdown. It has proven to be the most cost effective spacecraft in history to be used by NASA.[8]
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's Cygnus spacecraft, and Sierra Nevada Corporation's Dream Chaser spaceplane is expected to join them in 2024.[9] As of July 2023, it is the only reusable orbital cargo spacecraft in operation.
Crew Dragon's 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 is joined by Boeing's Starliner in this role. 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.
There are two variants of Dragon 2: Crew Dragon and Cargo Dragon.[6] Crew Dragon was initially called "DragonRider"[10][11] and it was intended from the beginning to support a crew of seven or a combination of crew and cargo.[12][13] 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.[14][15] For typical missions, Crew Dragon will remain docked to 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.[16][17][18][19][20][21] SpaceX uses the Falcon 9 Block 5 launch vehicle to launch Dragon 2.[5]
Crew Dragon incorporates an integrated pusher launch escape system consisting of eight SuperDraco engines, capable of accelerating the capsule away from the launch vehicle in an emergency. SpaceX originally intended to use the SuperDraco engines to land Crew Dragon on land, with parachutes and an ocean splashdown employed 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.[22] Propulsive landing was later cancelled, leaving ocean splashdown under parachutes as the only option.[23]
In 2012, SpaceX was in talks with Orbital Outfitters about developing space suits to wear during launch and re-entry.[24] Each crew member wears a custom space suit fitted for them. The suit is primarily designed for use inside the Dragon (IVA type suit): however, in the case of a rapid cabin depressurization, the suit can protect the crew members. The suit can also provide cooling for astronauts during normal flight.[25][26] 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 headquartersinHawthorne, California.[27][28][29] In October 2014, NASA selected the Dragon spacecraft as one of the candidates to fly American astronauts to the International Space Station, under the Commercial Crew Program.[30][31][32] 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".[33] SpaceX later decided to build a fifth Crew Dragon capsule, to be available by 2024.[34] SpaceX also manufactures 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,[35] while the face value of each seat has been estimated by NASA's Office of Inspector General (OIG) to be around US$55 million.[36][37][38] This contrasts with the 2014 Soyuz launch price of US$76 million per seat for NASA astronauts.[39]
Although Dragon 2 was intended from the earliest design concept to carry crew, or with fewer seats, both crew and cargo, a second round of multi-year cargo supply contracts (also known as CRS-2) was solicited by NASA in 2014, to supply the ISS in 2020–2024. This led to SpaceX proposing a separately-named model, Cargo Dragon, for this mission.[40] SpaceX won a contract award for Cargo Dragon as a result of the CRS-2 bid competition, with contracts awarded in January 2016 for six flights.
Cargo Dragon has now completed 9 successful missions to and from the ISS with 6 more planned.
Cargo Dragons are different from the crewed variant by launching without seats, cockpit controls, astronaut life support systems, and SuperDraco abort engines.[41][42] Cargo Dragon improves on many aspects of the original Dragon design, including the recovery and refurbishment process.[43]
In January 2022, NASA announced a planned date of January 2031 to de-orbit the ISS using a deorbit module and direct any remnants into a remote area of the South Pacific Ocean that has come to be known as the spacecraft cemetery.[44] NASA will launch the deorbiting spacecraft, a year before reentry, docking at the Harmony forward port either through a CBM or to PMA 2/IDA 2 after the removal of Axiom Orbital Segment. The spacecraft would only be functional during the final days of ISS, once the station's orbit has decayed to 220 km (140 mi). The spacecraft would then conduct one or more orientation burns to lower the perigee to 160 km (99 mi), followed by a final deorbiting burn.[45] In June 2024, NASA awarded a contract worth up to $843 million to SpaceX to build the deorbit vehicle, i.e, a flown Cargo Dragon 2 with an extended trunk, as it works to secure funding.[46][47] The follow on program is the Commercial LEO Destinations Program, meant to allow private industry to build and maintain their own stations, and NASA procuring access as a customer.
Dragon 2 includes the following features:[27][28][48]
A Dragon 2 spacecraft consists of a capsule and a trunk. While a new trunk is expended on each mission, the capsule is reusable. After earlier plans of SpaceX to use new capsules for every crewed flight for NASA[49] both agreed to reuse Crew Dragon capsules for NASA flights.[50][51] In 2022, SpaceX stated that a capsule can be reused up to fifteen times.[34] Cargo Dragon can carry 3,307 kg (7,291 lb) to the ISS. Crew Dragon has a capacity of four astronauts.[d] Above the seats, there is a three-screen control panel, a toilet (with privacy curtain), and the docking hatch. Ocean landings are accomplished with four main parachutes in both variants. The parachute system was fully redesigned from the one used in the prior Dragon capsule, due to the need to deploy the parachutes under a variety of launch abort scenarios.[53]
Crew Dragon has eight side-mounted SuperDraco engines, clustered in redundant pairs in four engine pods, with each engine able to produce 71 kN (16,000 lbf) of thrust to be used for launch aborts.[27] Each pod also contains four Draco thrusters that can be used for attitude control and orbital maneuvers. The SuperDraco engine combustion chamber is printed of Inconel, an alloy of nickel and iron, using a process of direct metal laser sintering. Engines are contained in a protective nacelle to prevent fault propagation if an engine fails.
Once in orbit, Dragon 2 is able to autonomously dock to the ISS. Dragon 1 was berthed using the Canadarm2 robotic arm, requiring substantially more involvement from ISS crew. Pilots of Crew Dragon retain the ability to dock the spacecraft using manual controls interfaced with a static tablet-like computer. 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". Also, the spacecraft will be able to return safely if a leak occurs "of up to an equivalent orifice of 6.35 mm [0.25 in] in diameter".[22]
Propellant and helium pressurant for both launch aborts and on-orbit maneuvering is contained in composite-carbon-overwrap titanium spherical tanks. A PICA-X heat shield protects the capsule during reentry. A reusable nose cone "protects the vessel and the docking adaptor during ascent and reentry",[22] pivoting on a hinge to enable in-space docking and returning to the covered position for reentry and future launches.[29]
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. As previously, the parachute compartments are located on the front of the capsule. Plans to land the capsule propulsively, using the engines used for launch escape, were abandoned in 2017. SpaceX was required by NASA to add an additional main parachute by default as a safety measure, after a Dragon 1 suffered a parachute malfunction. The company also improved on the design of the parachutes used on Dragon 1, developing new parachutes twice before being certified to fly with crew.[54]
The trunk is the third structural element of the spacecraft, containing solar panels, heat-removal radiators, and fins to provide aerodynamic stability during emergency aborts.[22]
The previous Cargo Dragon's deployable solar arrays have been eliminated and are now built into the trunk itself. This increases volume space, reduces the number of mechanisms on the vehicle and further increases reliability.
Announced on 29 August 2021 during the CRS-23 launch is a new feature called Extend-the-Lab installed in the Cargo Dragon. "Our new Cargo Dragon vehicle is also able to act as a laboratory in the advancement of science and research. We call this capability Extend-the-Lab. It allows some powered payloads to remain on Dragon for experimentation during the duration of the mission. This is especially helpful when there is limited to no space on station for additional science. And it also helps cut down the amount of time the crew has to move payloads in and out of Dragon. For CRS-23 there are 3 Extend-the-Lab payloads launching with the mission, and once docked, a 4th which is currently already on the space station will be added to Dragon".[55][56]
For Crew Dragon missions not involving docking, the capsule docking adapter which is normally used to dock with the ISS can be replaced by a domed plexiglass window. This provides panoramic views of space and the Earth like the Cupola Module on the ISS to provide interest and make up space left after removal of the docking adapter during flight.[57] The dome's first use was on the Inspiration4 flight.
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.[53]
On 16 September 2014, NASA announced that SpaceX and Boeing had been selected to provide crew transportation to 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.[58] Dragon was the less expensive proposal,[31] 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.[59]
In 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.[60]
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 the passengers approximately two hours prior to 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.[61]
The first automated test mission launched to the International Space Station (ISS) on 2 March 2019.[62] After schedule slips,[63] the first crewed flight launched on 30 May 2020[64] 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.[65] These plans were cancelled by September 2019.
Space Adventures contracted SpaceX for a five-day high elliptic orbit space tourism mission with a Crew Dragon in 2022.[66][67] 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.[68]
SpaceX planned a series of four flight tests for the Crew Dragon: a pad abort test, an unmanned orbital flight to the ISS, an in-flight abort test, and finally a crewed flight to the ISS,[69] which was initially planned for July 2019,[63] but after a Dragon capsule explosion, was delayed to May 2020.[70]
The pad abort test was conducted successfully on 6 May 2015 at SpaceX's leased SLC-40 launch site.[53] Dragon landed safely in the ocean to the east of the launchpad 99 seconds after ignition of the SuperDraco engines.[71] 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 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.[60][72] The test objective was to demonstrate sufficient total impulse, thrust and controllability to conduct a safe pad abort. A fuel mixture ratio issue was detected after the flight in one of the eight SuperDraco engines causing it to under perform, but did not materially affect the flight.[73][74][75]
On 24 November 2015, SpaceX conducted a test of Dragon 2's hovering abilities at the firm's rocket development facilityinMcGregor, 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.[76] The test vehicle was the same capsule that performed the pad abort test earlier in 2015; it was nicknamed DragonFly.[77]
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.[78] The Demo-1 mission completed the last milestone of the Commercial Crew Development program, paving the way to starting commercial services under an upcoming ISS Crew Transportation Services contract.[60][79] On 3 August 2018, NASA announced the crew for the DM-2 mission.[80] 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 the final Space Shuttle mission, STS-135.[81]
The first orbital test of Crew Dragon was an un-crewed mission, commonly called "Demo-1" and launched on 2 March 2019.[82][83] The spacecraft tested the approach and automated docking procedures with the ISS,[84] remained docked until 8 March 2019, then conducted the full re-entry, splashdown and recovery steps to qualify for a crewed mission.[85][86] Life-support systems were monitored for 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.[82][87]
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.[88][89] On the day of the explosion, the initial testing of the Crew Dragon's Draco thrusters was successful, with the anomaly occurring during the test of the SuperDraco abort system.[90]
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 the system 100 ms before firing damaged a check valve and resulted in the explosion.[90][91]
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.[92] The SuperDraco engine test was repeated on 13 November 2019 with Crew Dragon C205. The test was successful, showing that the modifications made to the vehicle were successful.[93]
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.[94]
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 a separation and abort scenario in the troposphereattransonic 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 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.[95] The test objective was to demonstrate the ability to safely move away from the ascending rocket under the most challenging atmospheric conditions of the flight trajectory, imposing the worst structural stress of a real flight on the rocket and spacecraft.[53] 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.[96]
Earlier, this test had been scheduled before the uncrewed orbital test,[97] however, SpaceX and NASA considered it safer to use a flight representative capsule rather than the test article from the pad abort test.[98]
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.[99] Capsule C205, originally planned for Demo-2 was used for the In-Flight Abort Test[100] with C206 being planned for use during Demo-2. This was the final flight test of 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.[101]
On 17 April 2020, NASA Administrator Jim Bridenstine announced the first crewed Crew Dragon Demo-2 to the International Space Station would launch on 27 May 2020.[102] 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.[103] The second launch attempt was successful, with capsule C206, later named Endeavour by the crew, launching on 30 May 2020 19:22 UTC.[104][105] The capsule successfully docked with the International Space Station on 31 May 2020 at 14:27 UTC.[106][107][108] 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 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".[109]
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 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 the trunk separation but with the parachutes it was a pretty significant jolt".[110]

Walker revealed at the briefing SpaceX plans to build a fifth and likely final Crew Dragon.
This is a firm fixed-price, indefinite-delivery/indefinite-quantity contract modification for the Crew-10, Crew-11, Crew-12, Crew-13, and Crew-14 flights. The value of this modification for all five missions and related mission services is $1,436,438,446. The amount includes ground, launch, in-orbit, and return and recovery operations, cargo transportation for each mission, and a lifeboat capability while docked to the International Space Station. The period of performance runs through 2030 and brings the total CCtCap contract value with SpaceX to $4,927,306,350
According to the NASA audit, the SpaceX Crew Dragon's per-seat cost works out at an estimated $55 million while a seat on Boeing's Starliner is approximately $90 million ...
Eventually, a round-trip seat on the Crew Dragon is expected to cost about $US55 million. A seat on Starliner will cost about $US90 million. That's according to a November 2019 report from the NASA Office of Inspector General.
NASA will likely pay about $90 million for each astronaut who flies aboard Boeing's CST-100 Starliner capsule on International Space Station (ISS) missions, the report estimated. The per-seat cost for SpaceX's Crew Dragon capsule, meanwhile, will be around $55 million, according to the OIG's calculations.
a highly-modified second-generation Dragon capsule fitted with myriad upgrades and changes – including new rocket thrusters, computers, a different outer mold line, and redesigned solar arrays – from the company's Dragon cargo delivery vehicle already flying to the space station.
'With [the addition of parachutes] and the angle of the seats, we could not get seven anymore', Shotwell said. "So now we only have four seats. That was kind of a big change for us".
Currently, the first uncrewed test of the spacecraft is expected to launch in May 2017. Sometime after that, SpaceX plans to conduct an in-flight abort to test the SuperDraco thrusters while the rocket is traveling through the area of maximum dynamic pressure – Max Q.
Shotwell said the company is planning an in-flight abort test of the Crew Dragon spacecraft before the end of this year, where the vehicle uses its thrusters to separate from a Falcon 9 rocket during ascent. That will be followed in 2017 by two demonstration flights to the International Space Station, the first without a crew and the second with astronauts on board, and then the first operational mission.
In the updated plan, SpaceX would launch its uncrewed flight test (DM-1), refurbish the flight test vehicle, then conduct the in-flight abort test prior to the crew flight test. Using the same vehicle for the in-flight abort test will improve the realism of the ascent abort test and reduce risk.This article incorporates text from this source, which is in the public domain.

After CRS-25, the next commercial cargo mission is NG-18, a Northrop Grumman Cygnus mission tentatively scheduled for mid-October. The SpaceX CRS-26 Dragon mission will follow late in the year, delivering among other cargo a set of solar arrays to be installed on the station by spacewalking astronauts.
