NASA is about to play ‘tag’ with asteroid Bennu: Here’s how it will work.

NASA’s OSIRIS-Rex spacecraft will “TAG” asteroid Bennu Tuesday (Oct. 20) and collect a sample for return to Earth. 

OSIRIS-REx is NASA’s first asteroid-sampling spacecraft. The “touch-and-go” (TAG) sample collection attempt involves a series of maneuvers that will bring the spacecraft down to the asteroid’s surface. The location selected for touchdown is called Nightingale, which is a rocky area measuring 52 feet (16 meters) in diameter and located in Bennu’s northern hemisphere, according to NASA.
