Cygnus is an expendable American automated cargo spacecraft designed for International Space Station (ISS) resupply missions. It was initially developed by Orbital Sciences Corporation with financial support from NASA under the Commercial Orbital Transportation Services (COTS) program. To create Cygnus, Orbital paired a pressurized cargo module, largely based on the Multi-Purpose Logistics Module, built by Thales Alenia Space and previously used by the Space Shuttle for ISS resupply, with a service module based on Orbital's GEOStar, a satellite bus. After a successful demonstration flight in 2013, Orbital was chosen to receive a Commercial Resupply Services (CRS) contract. A larger Enhanced Cygnus was introduced in 2015. Orbital Sciences merged into Orbital ATK in 2015; Northrop Grumman purchased Orbital ATK in 2018 and has continued to operate Cygnus missions. A further enlarged Mission B Cygnus is expected to be introduced in 2025.
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.
SpaceX CRS-1, also known as SpX-1, was SpaceX's first operational cargo mission to the International Space Station, under their Commercial Resupply Services (CRS-1) contract with NASA. It was the third flight for the uncrewed Dragon cargo spacecraft, and the fourth overall flight for the company's two-stage Falcon 9 launch vehicle. The launch occurred on 8 October 2012 at 00:34:07 UTC.
SpaceX CRS-2, also known as SpX-2, was the fourth flight for SpaceX's uncrewed Dragon cargo spacecraft, the fifth and final flight for the company's two-stage Falcon 9 v1.0 launch vehicle, and the second SpaceX operational mission contracted to NASA under a Commercial Resupply Services (CRS-1) contract.
SpaceX CRS-10, also known as SpX-10, was a Dragon Commercial Resupply Service mission to the International Space Station (ISS) which launched on 19 February 2017. The mission was contracted by NASA as part of its Commercial Resupply Services program and was launched by SpaceX aboard the 30th flight of the Falcon 9 rocket. The mission ended on 19 March 2017 when the Dragon spacecraft left the ISS and safely returned to Earth.
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-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-17, also known as SpX-17, was a Commercial Resupply Services mission (CRS) to the International Space Station that was launched aboard a Falcon 9 rocket on 4 May 2019. The mission was contracted by NASA and was flown by SpaceX. An umbilical connection from the strongback remained attached to the spacecraft and is visible in photos taken of it approaching & attached to the ISS.
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.
SpaceX CRS-20, also known as SpX-20, was a Commercial Resupply Services mission to the International Space Station (ISS) launched on 7 March 2020. The mission was contracted by NASA and flown by SpaceX. It was the final flight of Dragon 1 and concluded the NASA Commercial Resupply Services (CRS-1) contract extension.
SpaceX Dragon 1 is 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). It was succeeded by the Dragon 2 spacecraft which has both crewed and cargo versions.
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-25, also known as SpX-25, was a Commercial Resupply Service mission (CRS) to the International Space Station (ISS) that was launched on 15 July 2022. The mission was contracted by NASA and was flown by SpaceX using their reusable spacecraft, the Cargo Dragon. The vehicle delivered supplies to the crew aboard the ISS along with multiple pieces of equipment that will be used to conduct multiple research investigations aboard the ISS.
