Asteroids and comets are among the oldest objects in our solar system. They mostly reside at safe distances from Earth, but some find their way into our planetary backyard. “The Hunt for Space Rocks” chronicles JPLs pioneering work to understand asteroids and comets as part of NASA’s larger effort to protect our planet from cosmic marauders. From JPL’s effort to mount a mission to study the most famous comet of all – Halley’s comet – to the lab’s current role in planetary defense with its Center for Near Earth Object Studies (CNEOS). The documentary drives home a clear message: We need to find the asteroids and comets before they find us.
