NASA’s Lucy Mission launched in October of 2021 and will be the first to Jupiter’s Trojan asteroids. By the end of its twelve-year mission, the spacecraft will have flown by a record-breaking number of asteroids for a single mission (eleven and counting!).

Why does the mission’s asteroid count keep increasing? And how does the Lucy Team pinpoint the asteroid positions in the first place? 

Join a member of the Lucy Occultation Team for a deep dive into the science and adventure of observing asteroids by observing the shadows of these celestial bodies as they pass in front of distant stars (kind of like a mini solar eclipse). Stick around for a mission update about what the Lucy spacecraft observed on November 1 as it flew by the main belt asteroid Dinkinesh.
