Peggy Annette Whitson is an American biochemistry researcher, and astronaut working for Axiom Space. She retired from NASA in 2018, after serving as Chief Astronaut. Over all her missions, Whitson has a total of 665 days in space, more than any other American or woman.
Development of the Commercial Crew Program (CCDev) began in the second round of the program, which was rescoped from a smaller technology development program for human spaceflight to a competitive development program that would produce the spacecraft to be used to provide crew transportation services to and from the International Space Station (ISS). To implement the program, NASA awarded a series of competitive fixed-price contracts to private vendors starting in 2011. Operational contracts to fly astronauts were awarded in September 2014 to SpaceX and Boeing, and NASA expected each company to complete development and achieve crew rating in 2017. Each company performed an uncrewed orbital test flight in 2019.
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 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. Since 2020, when Dragon 2 flew its first crewed and uncrewed flights, it has proven to be the most cost-effective spacecraft ever used by NASA.
Crew Dragon Demo-2 was the first crewed test flight of the Crew Dragon spacecraft. The spacecraft, named Endeavour, launched on 30 May 2020 on a Falcon 9 rocket, and carried NASA astronauts Doug Hurley and Bob Behnken to the International Space Station in the first crewed orbital spaceflight launched from the United States since the final Space Shuttle mission in 2011, and the first ever operated by a commercial provider. Demo-2 was also the first two-person orbital spaceflight launched from the United States since STS-4 in 1982. Demo-2 completed the validation of crewed spaceflight operations using SpaceX hardware and received human-rating certification for the spacecraft, including astronaut testing of Crew Dragon capabilities on orbit.
Axiom Space, Inc., also known as Axiom Space, is an American privately funded space infrastructure developer headquartered in Houston, Texas.
SpaceX Crew-1 was the first operational crewed flight of a Crew Dragon spacecraft, and the maiden flight of the Crew Dragon Resilience spacecraft. It was also the second crewed orbital flight launch by the United States since that of STS-135 in July 2011. Resilience launched on 16 November 2020 at 00:27:17 UTC on a Falcon 9 from Kennedy Space Center Launch Complex 39A (LC-39A), carrying NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker, along with JAXA astronaut Soichi Noguchi, all members of the Expedition 64 crew. The mission was the second overall crewed orbital flight of the Crew Dragon.
The Boeing Orbital Flight Test-2 was a repeat of Boeing's unsuccessful first Orbital Flight Test (Boe-OFT) of its Starliner spacecraft. The uncrewed mission was part of NASA's Commercial Crew Program. OFT-2, using Starliner Spacecraft 2, launched 19 May 2022 and lasted 6 days. Starliner successfully docked with the International Space Station (ISS) on 21 May 2022. It stayed at the ISS for 4 days before undocking and landing in the White Sands Missile Range on 25 May 2022.
Axiom Mission 1 was a privately funded and operated crewed mission to the International Space Station (ISS). The mission was operated by Axiom Space out of Axiom's Mission Control Center MCC-A in Houston, Texas. The flight launched on 8 April 2022 from Kennedy Space Center in Florida. The spacecraft used was a SpaceX Crew Dragon. The crew consisted of Michael López-Alegría, a Spaniard-American and a professionally trained astronaut hired by Axiom, Eytan Stibbe from Israel, Larry Connor from the United States, and Mark Pathy from Canada.
The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational no earlier than 2025. NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.
Crew Dragon Resilience is the second operational Crew Dragon reusable spacecraft manufactured and operated by SpaceX. It first launched on 16 November 2020 to the International Space Station (ISS) on the SpaceX Crew-1 mission, the first operational flight of NASA's Commercial Crew Program. It was subsequently used for Inspiration4 in 2021, the first private spaceflight mission with an all-civilian crew, and the Polaris Dawn mission in September 2024.
Crew Dragon Endeavour is the first operational Crew Dragon reusable spacecraft manufactured and operated by SpaceX. The spacecraft is named after Space ShuttleEndeavour. 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, the private Axiom Mission 1 that launched in April 2022, and the SpaceX Crew-6 mission that launched in March 2023. It was last in orbit with the SpaceX Crew-8 mission from early March 2024 to late October 2024. Endeavour currently holds the single-mission record for the most time in orbit by an American crewed spacecraft at 235 days.
Expedition 67 was the 67th long-duration expedition to the International Space Station. The expedition began upon the departure of Soyuz MS-19 on 30 March 2022 with NASA astronaut Thomas Marshburn taking over as ISS commander. Initially, the expedition consisted of Marshburn and his three SpaceX Crew-3 crewmates Raja Chari, Kayla Barron, and Matthias Maurer, as well as Roscosmos cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov, who launched aboard Soyuz MS-21 on March 18, 2022 and transferred from Expedition 66 alongside the Crew-3 astronauts. However, continued international collaboration has been thrown into doubt by the 2022 Russian invasion of Ukraine and related sanctions on Russia.
SpaceX Crew-3 was the Crew Dragon's third NASA Commercial Crew operational flight, and its fifth overall crewed orbital flight. The mission successfully launched on 11 November 2021 at 02:03:31 UTC to the International Space Station. It was the maiden flight of Crew Dragon Endurance.
SpaceX Crew-4 was the Crew Dragon's fourth NASA Commercial Crew operational flight, and its seventh overall crewed orbital flight. The mission launched on 27 April 2022 at 07:52 UTC before docking with the International Space Station (ISS) at 23:37 UTC. It followed shortly after the private Axiom 1 mission to the ISS earlier in the month utilizing SpaceX hardware. Three American (NASA) astronauts and one European (ESA) astronaut were on board the mission.
Axiom Mission 2 was a private crewed spaceflight operated by Axiom Space. Ax-2 was launched on 21 May 2023 on a SpaceX Falcon 9, successfully docking with the International Space Station (ISS) on 22 May. After eight days docked to the ISS, the Dragon crew capsule Freedom undocked and returned to Earth twelve hours later.
Crew Dragon Endurance is the third operational SpaceX Dragon 2 reusable spacecraft manufactured and operated by SpaceX. It first launched on 11 November 2021 to the International Space Station (ISS) on the SpaceX Crew-3 mission. It has subsequently been used for the Crew-5 mission launched in October 2022 and the Crew-7 mission launched in August 2023. It is scheduled to next operate the private Fram2 spaceflight mission in 2025. The capsule was named in honor of the SpaceX and NASA teams who worked to build the spacecraft during the COVID-19 pandemic and Endurance, the ship used by Shackleton's Imperial Trans-Antarctic Expedition.
Axiom Mission 3 was a private spaceflight to the International Space Station. The flight launched on 18 January 2024, and lasted for 21 days, successfully splashing down in the Atlantic Ocean. It was operated by Axiom Space and used a SpaceX Crew Dragon spacecraft. The booster, B1080, had previously flown Axiom-2, among other high-profile missions.
SpaceX Crew-9 is the ninth operational NASA Commercial Crew Program flight and the 15th crewed orbital flight of a Crew Dragon spacecraft. Originally scheduled to launch a crew of four to the International Space Station (ISS) in mid-August 2024, the mission was delayed by more than a month due to technical issues with the Boeing Starliner Calypso spacecraft that was docked at the ISS for the Boeing Crew Flight Test. NASA ultimately decided to send the Starliner back to Earth uncrewed, launch Crew-9 with two crew members, and return with four crew members, including the two crew members of the Boeing Crew Flight Test. After that delay and other delays largely due to weather, Crew-9 launched on 28 September at 17:17:21 UTC.
