Why in the discussion?

Important point

  • This is the first American effort to collect asteroids sampling and return to Earth, before that, Japan has made some efforts in this area to some extent.
  • In the year 2020, scientists will collect samples collected by this vehicle and by 2023 it will return to Earth. 
  • Scientists are eager to study the material of carbon rich asteroids such as Bennu, which is proof of the initial construction of our Solar System 4.5 billion years ago.
  • Thus Bennu is similar to a celestial time capsule.
  • Meanwhile, a Japanese spacecraft named Ryugu, will depart from earth to collect samples of asteroids from June. This is Japan’s second asteroid mission.
