Why in the discussion?

After nearly two years of travel, NASA’s spacecraft Osiris-Rex reached the asteroids Bennu on December 3 and took a picture of a diamond-shaped rock. This spacecraft will revolve around Bennu’s orbit from the coming days that is, 31 December. It is noteworthy that no spacecraft has reached the orbit of such a small asteroid so far.

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.

About asteroids

  • Small orbiting bodies of the Sun between the orbits of Mars and Jupiter are called asteroids.
  • These arithmetic shaped planets are orbiting the Sun in the elliptical orbit.
  • Asteroids are the remains of planetary elements in which natural resources are contained in water, organic matter, metals etc.
  • Bennu is also an asteroid known as ‘1999 RQ36’.


  • On September 8, 2016 NASA launched the Spacecraft Osiris-REx from the Cape Canaveral Air Force Station, Florida, from the Atlas-U rocket.
  • This spacecraft has been built by Lockheed Martin Space Systems.
  • The full name of Osiris-REx is Origin, Spectral Interpretation, Resource Identification, Security-Regulith Exfoller, Asteroid Sample Return Mission.
  • This NASA Space Mission will collect and study the specimen from the asteroid Bennu near the Earth.
  • The purpose of this mission is to gather accurate information about the atmosphere and its texture on the asteroid.
  • This spacecraft will collect samples of rocks and mineral elements on the surface of asteroids with the help of its robotic arm.
  • There are five devices in this spacecraft, which are as follows –
♦ Osiris-Rex Laser Ultimate (OLA), 
♦ Osiris-Rex Thermal Emission Spectrometer (OTES), 
♦ Osiris-Rex Visible and Infrared Spectrometer (OVIRS), 
♦ Osiris-Rex Camera Suite (OCAMS) and 
♦ Regulith , X-ray Imaging Spectrometer (REXIS).
