CHINA’S MANNED MISSION

  • Recently, a Chinese spaceship “Shenzhou-12” carrying a three-person crew docked with China’s new space station module Tianhe-1.
  • his has come after the launch of the Tianzhou-2 cargo spacecraft, which carried vital supplies for the space station.

Important points:

  • The Shenzhou-12 craft connected with the Tianhe space station module about six hours after takeoff from the Jiuquan launch center in Gobi Desert.
  • The three-man crew will spend three months on the Tianhe module, which is orbiting at some 340km to 380km above the earth.
  • China is the third country after the former Soviet Union and the United States to carry out a manned mission on its own.
  • This is the first of two manned space missions planned for this year, part of an intense schedule of launches aimed at completing the Chinese space station in 2022.
  • At least five more missions are planned for the year, with the Shenzhou-13 manned mission, also carrying three astronauts, set for later this year.
  • The three astronauts are the first to take up residency in the main living module and will carry out experiments, test equipment, conduct maintenance and prepare the station for receiving two laboratory modules next year.
  • It was China’s seventh crewed mission to space but marked a number of firsts for the country – the first manned one during the construction of China’s space station, the first in nearly five years after the country’s last manned mission in 2016 and China’s longest crewed space mission to date.
  • It will help test technologies related to long-term astronaut-stays and health care, the recycling and life support system, the supply of space materials, extravehicular activities and operations, and in-orbit maintenance.
  • China is not a participant in the International Space Station (ISS), largely as a result of US objections to the Chinese program’s secrecy and close military ties.
  • The ISS is a joint project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and b (Canada).
  • However, China has been stepping up cooperation with Russia and a host of other countries, and its station may continue operating beyond the ISS, which is reaching the end of its functional life.
