New research reveals veins of carbonite materials in Bennu's boulders, as well as signs of organic minerals widespread across its surface. The variety of rock compositions on the asteroid's ...

Asteroid Bennu's most prominent boulder, a rock chunk jutting out 71 ft (21.7 m) from the asteroid's southern hemisphere, finally has a name. The boulder - which is so large that it was initially ...

Asteroid Bennu's boulder-covered surface gives it protection against small meteoroid impacts, according to observations of craters by NASA's OSIRIS-REx (Origins, Spectral Interpretation, Resource ...

The observations, however, suggested that Bennu's soft surface acts almost like a crumple zone of a car, absorbing a large portion of the impacts nearly without a trace.

A space rock is making big news this weekend. And it could make even bigger news next century. Potentially hazardous near-Earth asteroid Bennu, the subject of NASA's OSIRIS-REx mission that's set ...

The van-size spacecraft had to negotiate building-size boulders around the landing area to touch down on a relatively clear space that's only as large as a few parking spaces.

One outlier from the predicted shape model is the size of the large boulder near Bennu's south pole. The ground-based shape model calculated this boulder to be at least 33 feet (10 meters) in height.

Touchdown on Bennu will prove a bit more tricky than originally anticipated. As NASA reported months ago, Bennu is rockier than expected; it is home to large boulders that put the spacecraft at ...

The near-Earth asteroid Bennu has been in an orbit that brings it near to Earth for 1.75 million years, based on a study of craters on the asteroid’s surface.

ROUGH TERRAIN The boulder-strewn asteroid Bennu, shown here in a mosaic of images taken by the OSIRIS-REx spacecraft on December 2, is full of water-rich minerals. Univ. of Arizona/Goddard/NASA ...

“Both large craters and a widespread population of fractured boulders date back hundreds of millions of years to when Bennu was in the main asteroid belt,” Walsh said.
