SpaceX CRS-20, also known as SpaceX-20, is a Commercial Resupply Service mission to the International Space Station (ISS) launched on 7 March 2020.[1][6] The mission is contracted by NASA and was flown by SpaceX using Dragon. This was SpaceX's last flight for Dragon CRS and concludes the NASA CRS-1 contract extension. The second contract (CRS-2) was awarded in January 2016 and will begin with the SpaceX CRS-21 mission planned for October 2020 using Dragon 2.[7]

The Dragon capsule C112 used for CRS-20 previously flew to the ISS on CRS-10 and CRS-16.[8] It arrived at the ISS on 9 March at 10:25 UTC and was captured by the station's Canadarm2 robotic arm, the last-ever capture of a Dragon with Canadarm. Cargo Dragon 2 vehicles, which will replace Dragon 1, will dock directly at the space station.[9]

Launch schedule history

On February 2016, it was announced that NASA had awarded a contract extension to SpaceX for five CRS additional missions (CRS-16 to CRS-20).[10] On June 2016, NASA Inspector General report had this mission manifested for 2019,[11] but by June 2019 the launch had been pushed back to March 2020.[1]

Primary payload

NASA contracted for the CRS-20 mission from SpaceX and therefore determines the primary payload, date of launch, and orbital parameters for the Dragon CRS.[12] The CRS-20 mission carries 1977 kg of cargo to ISS.[13]

  • Science investigations: 960 kg
  • Vehicle hardware: 219 kg
  • Crew supplies: 273 kg
  • Spacewalk equipment: 56 kg
  • Computer resources: 1 kg
  • Unpressurized payloads: Bartolomeo Platform 468 kg

Bartolomeo (named for the younger brother of explorer Christopher Columbus), is an external payload platform developed by Airbus Defence and Space, German-built and operated by the European Space Agency. Bartolomeo provides power and data transmission for up to 12 payload slots and is the first external commercial research platform to be installed on the ISS.[14][15]

Along with Bartolomeo, the Dragon cargo mission delivers about a ton of scientific experiments, including biological research investigations studying microgravity's impact on stem cells, intestinal diseases and chemical reactions.[16] A new European platform was also robotically installed outside the space station on 2 April 2020, giving the international research lab a new outdoor deck to host a range of materials science, Earth observation and space science instruments.[17]

The Dragon spacecraft is also packed with spare parts and replacement hardware for the space station's research facilities and life support systems. The components include upgraded hardware for the station's urine processing system, which converts human waste into drinking water. The new components allow NASA teams to test out modifications designed to extend the lifetime of the urine processing system's distillation assembly ahead of future missions to the Moon and Mars, which will require longer-lasting life support equipment.[18][16]

The 20 CRS-1 missions by SpaceX carried more than 94,000 pounds (43000 kg) of cargo to the International Space Station, and returned about 74,000 pounds (33000 kg) of equipment and specimens to Earth, according to NASA.[19]
