In about two hours (21/10/2020, 00:15 AM CET), NASA spacecraft OSIRIS-REx will scoop up a sample of Asteroid Bennu. Watch it live on NASA TV.
OSIRIS-REx launched from Cape Canaveral, Florida, on Sept. 8, 2016, and arrived at Bennu in December 2018. Now at a distance from Earth of 330 Million Km, the probe will make a touch and go to the surface of Bennu and collect some surface samples. Plan is to return these samples to Earth in 2023.
Asteroids are relics of the earliest materials that formed our solar system, and studying such a sample will allow scientists to answer fundamental questions about the origins of the solar system. Furthermore, Bennu is a near-Earth asteroid (NEA) with possible risk of impacting the Earth in the late 2100s, so the mission is also exploring ways in which such a collision might be avoided.
