[2] 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.

In 1989, Voyager 2 flew past the moon at a distance of 40,000 km,[3] and discovered several cryovolcanoes on its surface.

[5][6] The largest technological challenge is to learn how to mine local surface nitrogen ice, and how to heat it for use as propellant.

[7][8] A rocket-powered vehicle, or "hopper", has several advantages due to the variety of terrain and a gravity of only 8% of that of Earth.
