OSIRIS-REx (for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA space mission which aims to bring back to Earth at the end of 2023 samples of the carbonaceous near-Earth asteroid Bennu.
The probe was launched in September 2016 and arrived near Bennu in December 2018. Since then, it has been in orbit mapping the entire surface of the asteroid in order to choose the best place to collect samples. The collection at the Nightingale site was a success in autumn 2020.
