Capturing a piece of an asteroid and bringing it to Earth is even more difficult than it is time-consuming. After four years in space, NASA’s OSIRIS-REx craft made a brief landing on the asteroid Bennu to collect samples of the ancient rock. Six months later, part of the spacecraft began its journey home to Earth, and earlier this fall, that sample collection canister landed, via parachute, in Utah. Scientists will be studying those samples of Bennu for decades in the hope of unlocking the mystery of how life on Earth began — but they’ve already learned enough to get them excited.

In this episode, we speak with Linda Shiner, the former editor of Air & Space / Smithsonian magazine, about the challenges and triumphs of the OSIRIS-REx mission, and what scientists hope it will teach us about how life on Earth began.
