categorical

This fall, a capsule carrying samples from the distant asteroid Bennu parachuted to Earth. It is a reward from the unmanned mission Osiris-Rex, which spent years exploring area rocks. Analyzing this materials will give scientists an unparalleled glimpse into situations through the early planet-forming days of the photo voltaic system, when Bennu shaped 4.5 billion years in the past.
