Here’s how it works. The near-Earth asteroid Bennu continues to reveal its secrets to NASA's OSIRIS-REx mission, which has been orbiting the space rock for nearly two years.

Five science instruments mapped Bennu's chemistry and mineralogy to determine the effect of sunlight on the asteroid's orbit. Cost of the mission, excluding launch, is $800 million.

Nearly 60 years later, NASA’s OSIRIS-REx mission returned from space with a sample of an asteroid named Bennu, similar to the one that rained rocks over Revelstoke. Our research team has ...

NASA says Bennu asteroid sample shows evidence of water, carbon Rocks and soil collected from the asteroid Bennu and brought back to Earth last month by NASA's OSIRIS-REx probe are rich in carbon ...

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.

Asteroid Bennu is the space rock with the highest known probability of hitting Earth in the next 200 years. NASA's OSIRIS-REx mission will help us protect ourselves.

Bennu isn’t an asteroid that will bring about worldwide devastation. If the asteroid were to collide with Earth, it would damage the planet outward up to 600 miles away from its impact zone ...

The results of this first Bennu analysis, NASA says, show that the asteroid has likely experienced multiple water-related episodes before it coalesced into the mess of debris we know today.

While Osiris-Rex has been orbiting Bennu, the probe has measured how much the asteroid's gravity pulled on it. At the same time, Bennu was also flinging marble-size bits of rock away from its surface.

If Bennu did slam into Earth, it wouldn’t wipe out life, dinosaur-style, but rather create a crater roughly 10 to 20 times the size of the asteroid, said Lindley Johnson, NASA's planetary ...
