Triton Hopper is a proposed NASA lander to Triton, the largest moon of Neptune. The idea is to harvest the abundant nitrogen ice on the surface of Triton and use it as propellant for multiple short flights and explore a variety of locations. The concept transitioned in March 2018 to Phase II to refine their designs and explore aspects of implementing the new technology.
