On September 24, 2023, a capsule from space parachuted down into the Utah desert. Tucked inside it were 4.5-billion-year-old bits of rock and dust from a faraway asteroid named Bennu collected by the OSIRIS-REx spacecraft. These pristine space rocks, which contain carbon and other building blocks of life, could rewrite scientists’ understanding of our solar system. In this episode, sit in mission control and ride aboard helicopters with asteroid mission leaders like Dante Lauretta and Mike Moreau for a behind-the-scenes look at the OSIRIS-REx sample return mission’s epic conclusion.
