Moments before sample collection, the OSIRIS-REx boom and sample collector shadow stretched across the surface of the asteroid Bennu. Most of those rocks are a few centimeters across. Credit: NASA/Goddard/University of Arizona/Lockheed Martin

UPDATE: The Bennu asteroid sample collection was successful! Almost too successful

Debris from the surface of the asteroid Bennu blows away under the influence of nitrogen gas jets from the OSIRIS-REx TAGSAM device. Some of this material was collected and will be returned to Earth in 2023. Credit: NASA/Goddard/University of Arizona

BOOP! NASA spacecraft OSIRIS-REx pokes an asteroid and collects the debris

On the asteroid Bennu, how much you weigh depends on where you are

Bennu is a half-kilometer-wide asteroid on a near-Earth orbit. This image by the OSIRIS-REx spacecraft shows it is a rubble pile, a collection of rocks held together by their own gravity. Credit: NASA/Goddard/University of Arizona/Lockheed Martin

Bennu: The moody face of a rubble pile asteroid… that's spitting rocks in space.
