To collect samples, OSIRIS-REx flings an orbital web around an asteroid.

101955 One of Earth's nearest planetary neighbours is Bennu, an approximately skyscraper-sized asteroid that NASA's OSIRIS-REx probe has called home since late 2018. On Dec. 3, 2018, OSIRIS-REx touched down, and it immediately started to encircle Bennu in a complicated web of observations. On May 10, 2021, OSIRIS-REx will fly back to Earth from Bennu and bring with it more than 60 grammes of asteroid sample. The entire mission's course during its time at Bennu is shown in this narrated film.
