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.
The mission’s thrilling finale will take place on September 24, 2023, as OSIRIS-REx releases a capsule containing the Bennu samples for touchdown in the Utah desert.
