Solar System Voyager (SSVG)

SSVG is simulation software that allows us to fly our own spacecrafts in the solar system. Each spacecraft has three propulsion systems: a chemical propulsion engine, an electric propulsion engine, and a solar sail.

Fly your own spacecrafts in the precisely simulated solar system.
