The OSIRIS-REx is expected to land on Bennu and attempt to return to Earth with at least 60 grams of sample material from the asteroid.

As the time draws closer for NASA’s OSIRIS-REx sample-gathering spacecraft to land on the asteroid Bennu, researchers continue to provide further insights into the nature of this massive space rock, Science Alert reports.

According to the media outlet, a new global spectral survey of Bennu, led by Amy Simon of NASA-Goddard, has confirmed the presence of organic and carbon-bearing materials on the asteroid’s surface, apparently making it the first “concrete detection” of such substances on a near-Earth asteroid.

Also, the efforts of a team of scientists led by Michael Daly of York University in Toronto, Canada, have yielded a “detailed 3D digital terrain map of the asteroid”.

And the analysis of carbonate materials present in some of the boulders on the asteroid’s surface appear to hint at the presence of an “asteroid-scale hydrothermal system” on the “parent body” that produced Bennu.

The OSIRIS-REx is expected to land on Bennu and attempt to return to Earth with at least 60 grams of sample material from the asteroid.
