A small capsule carrying pristine specimens from an asteroid parachuted to landing in the Utah desert Sunday, capping a seven-year voyage through the Solar System to bring home samples for eager scientists seeking clues about the origins of life.
NASA’s OSIRIS-REx mission brought back the largest unspoiled sample of material ever returned to Earth from beyond the Moon, probably on the order of about 250 grams, or roughly 8 ounces, according to estimates. The spacecraft collected the samples from asteroid Bennu, a loosely-bound rocky world about the size of a small mountain, during a touch-and-go landing in October 2020.
It’s the third asteroid sampling mission in history, and the first for the United States, following two Japanese spacecraft that returned a smaller quantity of asteroid specimens to Earth in 2010 and 2020.
