Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and since late 2018, the place that NASA’s OSIRIS-REx mission has called home.
When OSIRIS-REx arrived on Dec.
3, 2018, it began wrapping Bennu in a complex web of observations.
OSIRIS-REx departs Bennu on May 10, 2021, on a return voyage to Earth, bringing with it over 60 grams of sample collected from the asteroid.
