Some of the first science results from the Bennu sample are in. They indicate that Bennu may have had a watery past.

NASA’s OSIRIS-REx mission delivered samples of the asteroid Bennu to researchers on Earth, providing a look at pristine materials that formed early on in the Solar System’s history.

Researchers have discovered that the samples are unaltered and haven’t melted and resolidified since their formation.

One surprising discovery is that the samples mirror the rock found at Earth’s mid-ocean ridges, suggesting they encountered water for long periods.
