Abstract
To alter the orbit of a Near Earth Asteroid (NEA) over an extended period, we propose to alter the NEA albedo to either diminish or enhance the Yarkovsky effect. At present, the albedo change mechanism that appears the most effective involves a device that dispenses charged powder onto the NEA surface which is itself ionized by ultraviolet radiation. Electrostatic attraction provides the dominant force that attracts and binds the powder to the surface. The albedo change dispenser described here is based upon triboelectric powder dispensing technology. We describe the design details and the constraints on particle size and dispensing speed.
