GS Paper - 3 (Space Technology)

NASA has again delayed the upcoming launch of the agency's SpaceX Crew-3 mission to November 10 because of weather concerns. SpaceX noted there was an 80 percent chance of favourable weather for the new date. Following Crew-2's return to Earth, Falcon 9 will launch Dragon's third long-duration crew mission to the Space Station as soon as on 10 November 2021.


  1. The Crew-3 launch to the International Space Station was earlier planned for 31 October 2021 but was postponed, due to unfavourable weather, to 3 November 2021 and then delayed to 6 November 2021.
  2. The SpaceX Crew Dragon spacecraft and Falcon 9 rocket are in good shape and will remain at Launch Complex 39A at Kennedy.
  3. This is the third crew rotation mission with astronauts on the SpaceX Crew Dragon spacecraft and the fourth flight with astronauts, including the Demo-2 test flight, as part of the agency's Commercial Crew Programme.
  4. The Crew-3 astronauts are also scheduled to conduct many additional experiments and technology demonstrations during their mission.
  5. Crew-3 is crucial for the testing of new upgrades to the space station's Environmental Control and Life Support System (ECLSS), including the newly installed toilet, the Brine Processing Assembly, carbon dioxide scrubbers, and two new hydrogen sensors slated to arrive aboard a SpaceX Cargo Dragon in late December.
