The AZ meteorite fell near the Costa Rican town of the same name, coincidentally also in 2019, and was donated to the Chicago Field Museum. As a CM2 carbonaceous chondrite, its composition is ...

In 2019, NASA's OSIRIS-REx spacecraft sent back images of a geological phenomenon no one had ever seen before: pebbles were flying off the surface of the asteroid Bennu.

This helped OSIRIS-REx to scoop up 121.6 g (4.29 oz), far more than the amount that would have made the mission a success. By returning the sample to Earth, the asteroid's chemical profile was ...

2.9K. Scientists from NASA’s OSIRIS-REx asteroid sample return mission recently delivered remarkable findings about asteroid 101955 Bennu after the mission returned its samples to Earth in 2023.

A meteorite on Earth holds new evidence that asteroids do indeed mysteriously spit out pebbles, a new study finds. In 2019, NASA's OSIRIS-REx spacecraft discovered a strange new phenomenon when ...

Although NASA won’t know exactly how much material is in the OSIRIS-REx capsule until it returns in September 2023, astromaterials curator Nicole Lunning says she expects an amount “at least ...

Since arriving at the asteroid, Osiris-rex has been busy taking measurements and sizing Bennu up. It performed close flybys to get a high-resolution look at the surface and caught the asteroid ...

In December, 16 years after kneeling over a meteorite in Antarctica, and 14 years after the fateful call from Michael Drake, OSIRIS-REx had arrived at asteroid Bennu. Preparations began for the ...

Asteroid Bennu particles coat the base of the OSIRIS-REx science canister. One of these small fragments, or one like them, is headed for public display at the Smithsonian on Nov. 3.

Meteorite hunter Robert Ward has donated a piece of one of the rarest meteorites ever found to the UA Lunar and Planetary Laboratory to possibly help answer questions regarding the earliest forms ...

“From OSIRIS-REx we know that these particle ejection events are much more frequent than these high-velocity impacts,” said Heck, “so they probably play a more important role in determining the makeup ...
