Crew-2 Mission – UPSC Prelims

Demo-2 Mission:
  • In May 2020, NASA and SpaceX launched the Demo-2 test mission.
  • The mission carried two astronauts to the International Space Station (ISS).
  • Aim: The aim of this mission was to test flight to see if SpaceX capsules could be used on a regular basis to ferry astronauts to and from the ISS.
Crew-1 Mission:
  • After the success of Demo-2, Crew-1 was launched in November 2020. It was the first of six crewed missions between NASA and SpaceX, marking the beginning of a new era in the US for space travel.
  • Purpose: The crew together with expedition 64 members conducted microgravity studies at the ISS. It included materials to investigate food physiology meant to study the effects of dietary improvements on immune function and the gut microbiome and how those improvements can help crews adapt to spaceflight.
Crew-2 Mission:
  • Crew-2 Mission is the second crew rotation of the SpaceX Crew Dragon and the first with international partners.
  • The mission carried four astronauts to ISS. Among them, two are from NASA and two are from the Japan Aerospace Exploration Agency (JAXA) and the European Space Agency(ESA).
  • The central focus of the mission will be to continue research on a series of Tissue Chips in Space studies.
Tissue Chips:
  • Tissue Chips are small models of human organs that contain multiple cell types that behave similarly to the human body organs.
  • According to NASA, these chips can potentially speed up the process of identifying safe and effective drugs and vaccines.
  • Scientists can use these tissue chips in space to study diseases that affect specific human organs, which would take months or years to develop on Earth.
