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. Dragon 2 is a class of partially reusable spacecraft developed, manufactured, and operated by the American space company SpaceX for flights to the International Space Station (ISS) and private spaceflight missions. The spacecraft, which consists of 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 ca 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… Dragon 2 is a class of partially reusable spacecraft developed, manufactured, and operated by the American space company SpaceX for flights to the International Space Station (ISS) and private spaceflight missions. The spacecraft, which consists of 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, 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, a duty it shares with Northrop Grumman's Cygnus spacecraft. As of January 2025, it is the only reusable orbital cargo spacecraft in operation. 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 the trunk's structure, replacing the deployable panels of its predecessor, Dragon 1. On Cargo Dragon missions, the trunk can also be used to transport unpressurized payloads, such as the Roll Out Solar Array, or it can be fitted with a "boost kit" to perform reboosts of 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 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. When the capsule returns to Earth, a PICA-3 heat shield safeguards 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, the use of the SuperDraco thrusters for propulsive landing was enabled again, but only as a backup for parachute emergencies. The pad abort test was conducted successfully on May 6, 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 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 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 November 24, 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 was the same capsule that performed the pad abort test earlier in 2015; it was nicknamed DragonFly. The Crew Dragon in-flight abort test was launched on January 19, 2020, at 15:30 UTC from LC-39A on a suborbital trajectory to conduct 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 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
