This combination of 2019 and 2021 images made available by NASA shows how the local surface of Bennu changed after the OSIRIS-REx spacecraft took a sample of the asteroid on Oct. 20, 2020. The earlier image, top, was taken on March 7, 2019, and the bottom was taken on April 7, 2021, as part of final observations to document the surface after sample acquisition. The Nightingale site is located in the relatively clear patch just above the crater's center - visible in the center of the earlier image. The large, dark boulder located at the center right measures 43 feet (13 meters) on its longest axis.

The earlier portray, top, used to be taken on March 7, 2019, and the backside used to be taken on April 7, 2021, as share of ultimate observations to doc the floor after sample acquisition.

CAPE CANAVERAL, Fla. (AP) — A NASA spacecraft left a huge quantity at an asteroid when it grabbed a load of rubble final year for return to Earth, unique photos published Thursday.

The Osiris-Rex spacecraft made one final flyby of asteroid Bennu on April 7 to engage photos of the disturbance left by October’s sample series.

A depression is viewed the set up Osiris-Rex penetrated the asteroid’s floor. Boulders possess been hurled by the pressurized nitrogen gas that used to be fired at the bottom to churn up fabric for vacuuming, and by the spacecraft’s getaway thruster. One 1-ton boulder used to be flung an estimated 40 toes (12 meters).

The Osiris-Rex team meticulously plotted the remaining flyover to be certain the most racy photography. The photos possess been taken around noontime to lead particular of shadows and better look the changes on Bennu’s rocky floor.

“These observations weren’t in the authentic mission conception, so we possess been angry to return and doc what we did,” the College of Arizona’s Dathon Golish acknowledged in a assertion.

Osiris-Rex will toddle away Bennu’s vicinity subsequent month and head support in direction of Earth with its precious 2-pound (1-kilogram) sample load. It’s ensuing from arrive in 2023.

The portray voltaic-orbiting, carbon-rich asteroid is 182 million miles (293 million kilometers) from Earth. By discovering out objects of it, scientists hope to better sign how our portray voltaic machine’s planets formed and the arrangement in which other folks must react if an asteroid endangers Earth.
