Spacecraft call signs are radio call signs used for communication in crewed spaceflight. These are not formalized or regulated to the same degree as other equivalent forms of transportation, like aircraft. The three nations currently launching crewed space missions use different methods to identify the ground and space radio stations; the United States uses either the names given to the space vehicles or else the project name and mission number. Russia traditionally assigns code names as call signs to individual cosmonauts, more in the manner of aviator call signs, rather than to the spacecraft.
Expedition 31 was the 31st long-duration expedition to the International Space Station (ISS). It began on 27 April 2012 with the departure from the ISS of the Soyuz TMA-22 spacecraft, which returned the Expedition 30 crew to Earth. The expedition ended on 1 July 2012, when crew members Oleg Kononenko, André Kuipers and Don Pettit departed from the ISS aboard Soyuz TMA-03M, marking the beginning of Expedition 32.
Dragon 2 is a class of partially reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX, primarily for flights to the International Space Station (ISS). SpaceX also launches private missions, such as Inspiration4 and Axiom Space Missions. There are two variants of the Dragon spacecraft: Crew Dragon, a spacecraft 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.
SpaceX CRS-12, also known as SpX-12, was a Commercial Resupply Services mission to the International Space Station launched on 14 August 2017. The mission was contracted by NASA and was flown by SpaceX using a new Dragon capsule. The Falcon 9 rocket's reusable first stage performed a controlled landing on Landing Zone 1 (LZ1) at Cape Canaveral Air Force Station. After delivering more than 2,900 kilograms (6,400 lb) of cargo, the Dragon spacecraft returned to Earth on 17 September 2017.
Crew Dragon Demo-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 following a successful splashdown on 8 March 2019 at 13:45:08 UTC.
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 Douglas Hurley and Robert 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.
Dragon, also known as Dragon 1 or Cargo Dragon, was a class of fourteen partially reusable cargo spacecraft developed by SpaceX, an American private space transportation company. The spacecraft flew 23 missions between 2010 and 2020. Dragon was launched into orbit by the company's Falcon 9 launch vehicle to resupply the International Space Station (ISS).
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.
SpaceX CRS-21, also known as SpX-21, was a Commercial Resupply Service mission to the International Space Station which launched on 6 December 2020. The mission was contracted by NASA and was flown by SpaceX using a Cargo Dragon 2. This was the first flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. This was also the first Cargo Dragon of the new Dragon 2 variant, as well as the first Cargo Dragon flight that was docked at the same time as a Crew Dragon spacecraft. This mission used Booster B1058.4, becoming the first NASA mission to reuse a booster previously used on a non-NASA mission. This was also first time SpaceX launched a NASA payload on a booster with more than one previous flight.
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, an American born in Spain 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 a Crew Dragon spacecraft manufactured by SpaceX and built under NASA's Commercial Crew Program. In November 2020, it was launched into orbit to the International Space Station as part of the Crew-1 mission. With crew prompting, Resilience docked autonomously to the station at 04:01 UTC on 17 November 2020, or Day 2 of the mission, marking the first operational docking of a Crew Dragon and the first operational docking of the Commercial Crew Program. The mission carried four additional members of Expedition 64 to the three already on station.
Crew Dragon Endeavour is a Crew Dragon space capsule manufactured and operated by SpaceX and used by NASA's Commercial Crew Program. As of 2023 it has successfully completed four crewed missions to the International Space Station (ISS). It was first launched into orbit atop a Falcon 9 rocket on 30 May 2020 and successfully docked to the International Space Station (ISS) as part of the Crew Dragon Demo-2 mission. This was the first crewed flight test of a Dragon capsule, carrying Doug Hurley and Bob Behnken on first crewed orbital spaceflight from the United States since STS-135 in July 2011 and the first crewed orbital spaceflight by a private company. On 2 August 2020 it returned to Earth. The spacecraft was named by Hurley and Behnken after the Space ShuttleEndeavour, aboard which they first flew into space during the STS-127 and STS-123 missions, respectively. The name Endeavour is also shared by the command module of Apollo 15. The spacecraft's second mission, Crew-2, ended 8 November 2021 after having spent almost 200 days in orbit. Crew Dragon Endeavour set the record for the longest spaceflight by a U.S. crew vehicle previously set by her sibling Crew Dragon Resilience on 2 May 2021. Collectively, Endeavour has spent over 450 days in orbit the most time so far by a crewed spacecraft, surpassing Space Shuttle Discovery.
