NIAC Award: Hopping Probes for Interior Mapping of Small Solar System Bodies

Gravity Popper mission concept: A spacecraft deploys a swarm of hopping probes to the surface of a small body and then tracks their trajectories to precisely and iteratively refine a model of the body’s gravity field and internal structure. (Credits: Benjamin Hockman)
