To Bennu and Back: Journey’s End

OSIRIS-REx is NASA’s first asteroid sample return mission. It launched in September 2016 on a journey to explore a near-Earth asteroid called Bennu. In October 2020, the spacecraft ventured to the asteroid’s surface and collected about 250 grams of material for delivery to Earth. Now, two years and four months after leaving Bennu, OSIRIS-REx is closing in on the place where its journey began. The mission’s thrilling finale will take place on September 24, 2023, as a capsule containing the Bennu samples touches down in Utah’s West Desert.
