As observed in the unique orbits of cosmic dust particles, at small length scales,
environmental forces such as solar pressure and the Loretz force can compete with gravity so
significantly accelerate a body in space. We propose to employ recent advances in nanofabrication
to create a new category of extremely small, low-cost, expendable spacecraft which capitalize on
this scaling to enable propellantless propulsion. Such devices could open up new spacecraft
mission opportunities, including distributed sensing, scientific research, exploration, and in-orbit
inspection of larger satellites.
