Dragon capsuleC106 made its third flight on CRS-19 having previously flown on CRS-4 and CRS-11. Dragon successfully returned to Earth on 7 January 2020 after a month-long stay at the ISS.
In February 2016, it was announced that NASA had awarded a contract extension to SpaceX for five CRS additional missions (CRS-16 toCRS-20).[7] In June 2016, a NASA Inspector General report had this mission manifested for December 2018.[8] The mission was later delayed to 15 October 2019,[9] but launched in December 2019.[6]
On 5 December 2019, CRS-19 launched successfully, followed by a successful first stage landing on the bargeOf Course I Still Love You.[10]
NASA has contracted for the CRS-19 mission from SpaceX and therefore determines the primary payload, date/time of launch, andorbital parameters for the Dragonspace capsule. CRS-11 carried a total of 2,617 kg (5,769 lb) of material into orbit. This included 1,693 kg (3,732 lb) of pressurised cargo with packaging bound for the International Space Station, and 924 kg (2,037 lb) of unpressurised cargo composed of theKibō-mounted Hyperspectral Imager Suite (HISUI) from Japan, the Robotic Tool Stowage (RiTS) platform, and a replacement lithium-ion battery for the station's solar array truss.[5][1]
The following is a breakdown of cargo bound for the ISS:[5]
Science investigations: 977 kg (2,154 lb)
Crew supplies: 256 kg (564 lb)
Vehicle hardware: 306 kg (675 lb)
Spacewalk equipment: 64 kg (141 lb)
Computer resources: 15 kg (33 lb)
External payloads:
Hyperspectral Imaging Suite (HISUI): ~500 kg (1,100 lb)[11]
Among the science experiments transported to the station are theAnheuser-Busch-sponsored Germination of ABI Voyager Barley Seeds in Microgravity, the Confined Combustion experiment, and 40 genetically engineered mice as part of theRodent Research-19 experiment.[12][13]
A number ofCubeSats were launched on CRS-19. TheELaNa-25B flight included AzTechSat-1, SORTIE, and CryoCube, while the ELaNa-28 flight included CIRiS and EdgeCube.[12] Othersmall satellites launched on this mission include QARMAN and MakerSat-1.[13]
Launches are separated by dots ( • ), payloads by commas ( , ), multiple names for the same satellite by slashes ( / ). Crewed flights are underlined. Launch failures are marked with the † sign. Payloads deployed from other spacecraft are (enclosed in parentheses).
