Hi Walter,

Thanks for the question. Navigation in deep space can be accomplished by a few methods. First, there is differential thrust due to radiation pressure (the momentum transfer of photons). Second, there can be ion engines which eject ions and thereby give thrust. Third, there is the mainstay of compressed gases (a fuel and an oxidizer) used for thrust.

I hope this helps. Please let me know if you have more questions. Thanks Jeff Grell
