Discovery Program

Comet Hopper (CHopper) was a proposed lander to NASA's Discovery Program that, had it been selected, would have orbited and landed multiple times on Comet Wirtanen as it approached the Sun. The proposed mission was led by Jessica Sunshine of the UMD, working with Lockheed Martin to build the spacecraft and the NASA Goddard Spaceflight Center to manage the mission.^[1]
