Nearly two years after launch, the University of Arizona-led OSIRIS-REx mission caught its first glimpse of the asteroid Bennu on Aug. 17 from 1.4 million miles away. The asteroid appeared as a ...

Bennu is classified as a “potentially hazardous asteroid,” meaning the object is more than 460 feet (140 meters) wide and could theoretically come within 4.65 million miles of Earth.

On Sunday, Sept. 24, 2023, the spacecraft will fly by Earth and drop off what is expected to be at least a cupful of rubble it grabbed from the asteroid Bennu, closing out a seven-year quest.

A series of images from NASA’s OSIRIS-REx mission show the spacecraft approach and touch down on asteroid Bennu’s surface, over 200 million miles away from Earth, to collect a sample on ...

In 2018, it arrived at Bennu, a near-Earth asteroid as wide as the Sears Tower is tall. The mission collected pieces of the asteroid and brought them back to Earth in 2023.

The OSIRIS-APEX mission, a follow-up to OSIRIS-REx, which successfully returned a sample from asteroid Bennu in 2023, has repurposed the spacecraft to visit a new target, asteroid Apophis.

Because this asteroid will zoom by Earth in 2029, a detailed study of its trajectory will deliver even further restrictions on the fifth force than what Bennu could provide.

I knew that the engineering team leaned toward an overabundance of caution: They didn’t want the asteroid ... at the University of Arizona and the OSIRIS-REx principal investigator, speaks at a press ...
