NASA mission catches nearby asteroid ejecting material into space
(CNN)NASA’s OSIRIS-REx mission arrived at near-Earth asteroid Bennu a year ago, and the spinning top-shaped space rock has been full of surprises. The latest findings now classify it as an active asteroid with observable events happening on the surface.
OSIRIS-REx and Bennu got to meet face-to-face on December 3 of last year. OSIRIS-REx has been orbiting the asteroid, which is 70 million miles from Earth, since December 31, 2018. It’s a “rubble pile” asteroid, a grouping of rocks held together by gravity rather than a single object.
