OSIRIS-REx Sample Site Selection Trailer

NASA's mission to collect samples from asteroid Bennu is its most ambitious since the Apollo program. After a two-year journey, including a gravity assist from Earth, the spacecraft arrived at Bennu. Initially seen as tiny pixels, Bennu revealed itself as a rugged world with giant boulders. The spacecraft mapped Bennu in unprecedented detail, and the mission team analyzed the data to select the best sample site. With months to go before collection, the team narrowed down to four potential sites.
