Pellet simulator

Back to Learn

Finding very sensitive trajectories, like those requiring multiple gravity assists, is a very time consuming trial and error process. This tool allows you to try a whole range of velocities at once to narrow down the trajectory much faster. The idea is neither new nor mine, this is just an implementation.
