Space Project SEE for Measuring G and its Possible Spatial and Time Variations

A SEE (Satellite Energy Exchange) mission is designed to make extremely accurate measurements on fundamental gravitation by observing the orbital perturbation of unconstrained orbiting test bodies in a femto-g to atto-g environment. A SEE mission will use novel and original test body dynamics. Gravitation is the missing link in unification theory. The broad objective of a SEE mission is to support development of gravity theory and unification theory by carrying out sensitive gravitational tests capable of discriminating among alternative theories. A SEE mission will introduce and utilize new technology for near-zero-g environment creation, passive cryogenic temperature control, passive station-keeping capability, and non-contact sub-micron-accuracy distance measurement, all of which promise to have applications in a wide variety of spacecraft.
