Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences for eight Cygnus flights, covering deliveries to 2016. The Falcon 9 and Antares rockets were also developed under the CRS program to deliver cargo spacecraft to the ISS.
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-9, also known as SpX-9, is a Commercial Resupply Service mission to the International Space Station which launched on 18 July 2016. The mission was contracted by NASA and is operated by SpaceX using a Dragon capsule.
SpaceX CRS-11, also known as SpX-11, was a Commercial Resupply Service mission to the International Space Station, launched successfully on 3 June 2017. The mission was contracted by NASA and was flown by SpaceX. The mission utilized a Falcon 9 launch vehicle and was the first reuse of C106, a CRS Dragon cargo vessel that was previously flown on the CRS-4 mission.
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.
SpaceX CRS-13, also known as SpX-13, was a Commercial Resupply Service mission to the International Space Station launched on 15 December 2017. The mission was contracted by NASA and is flown by SpaceX. It was the second mission to successfully reuse a Dragon capsule, previously flown on CRS-6. The first stage of the Falcon 9 Full Thrust rocket was the previously flown, "flight-proven" core from CRS-11. The first stage returned to land at Cape Canaveral's Landing Zone 1 after separation of the first and second stage.
SpaceX CRS-14, also known as SpX-14, was a Commercial Resupply Service mission to the International Space Station launched on 2 April 2018. The mission was contracted by NASA and was flown by SpaceX. This mission reused the Falcon 9 first stage booster previously flown on CRS-12 and the Dragon capsule flown on CRS-8.
SpaceX CRS-15, also known as SpX-15, was a Commercial Resupply Service mission to the International Space Station launched 29 June 2018 aboard a Falcon 9 rocket. The mission was contracted by NASA and flown by SpaceX.
SpaceX CRS-18, also known as SpX-18, was SpaceX's 18th flight to the International Space Station under the Commercial Resupply Services program for NASA. It was launched on 25 July 2019 aboard a Falcon 9 rocket.
SpaceX CRS-19, also known as SpX-19, was a Commercial Resupply Service mission to the International Space Station. The mission is contracted by NASA and was flown by SpaceX on a Falcon 9 rocket.
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 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.
SpaceX CRS-22, also known as SpX-22, was a Commercial Resupply Services (CRS) mission to the International Space Station (ISS) that launched at 17:29:15 UTC on 3 June 2021. The mission is contracted by NASA and is flown by SpaceX using a Cargo Dragon 2. This is the second flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016.
SpaceX CRS-23, also known as SpX-23, was a Commercial Resupply Service mission to the International Space Station, successfully launched on 29 August 2021 and docking the following day. The mission was contracted by NASA and was flown by SpaceX using the Cargo Dragon C208. This was the third flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. It was the second mission for this reusable capsule.
SpaceX CRS-24, also known as SpX-24, was a Commercial Resupply Service mission to the International Space Station launched on 21 December 2021, at 10:07:08 UTC. The mission is contracted by NASA and is flown by SpaceX using a Cargo Dragon. This is the fourth flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016.
Dragon C208 is the first Cargo Dragon 2 spacecraft, and the first in a line of International Space Station resupply craft which replaced the Dragon capsule, manufactured by SpaceX. The mission is contracted by NASA under the Commercial Resupply Services (CRS) program. It flew for the first time on the CRS-21 mission on 6 December 2020. This was the first flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. This was also the first time a Cargo Dragon was docked at the same time as a Crew Dragon spacecraft. This mission used Booster B1058.4.
SpaceX CRS-26, also known as SpX-26, was a Commercial Resupply Service mission to the International Space Station (ISS) launched on 26 November 2022. The mission was contracted by NASA and flown by SpaceX using a Cargo Dragon. This was the sixth flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016.
Dragon C209 is the second Cargo Dragon 2 spacecraft, and the second in a line of International Space Station resupply craft which replaced the Dragon capsule, manufactured by SpaceX. The missions are contracted by NASA under the Commercial Resupply Services (CRS) program. It was being flown for the first time on the CRS-22 mission on 3 June 2021. This was the second flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. This was also the second time a Cargo Dragon was docked at the same time as a Crew Dragon spacecraft, SpaceX Crew-2. This mission used a new Booster B1067.1.
SpaceX CRS-28, also known as SpX-28, is a Commercial Resupply Service mission to the International Space Station (ISS) launched on 5 June 2023. The mission was contracted by NASA and flown by SpaceX using Cargo Dragon C208. It was the eighth flight for SpaceX under NASA's CRS Phase 2.
SpaceX CRS-29, also known as SpX-29, is a Commercial Resupply Service mission to the International Space Station (ISS) launched on 10 November 2023. The mission is contracted by NASA and is scheduled to be flown by SpaceX using Cargo Dragon C211. This will the seventh flight for SpaceX under NASA's CRS Phase 2.
