NASA’s OSIRIS-REx asteroid probe is giving scientists an even better look at the surface of the space rock known as Bennu now that it’s moved even closer to the object.

Despite the slightly higher chance of impact, the risks from Bennu shouldn’t keep anyone awake at night. There’s more than a 99.9 percent chance that Bennu will not hit Earth in the next three ...

On October 22, two days after touching Bennu, engineers realized that OSIRIS-REx's Touch-and-Go Sample Acquisition Mechanism (TAGSAM) sampling head on was leaking precious rocks and dust.

The Field Museum received a rare, pristine sample of asteroid Bennu from NASA — a "time capsule" from the early solar system, untouched for 4.6 billion years. Scientists will study the carbon ...
