Clocks have always played a fundamental role in the development of gravitational and relativity theories. The advent of atomic clocks with stability in the 10-l6 domain provides measurement capability for both distance and time measurement at a level significant for the testing of relativistic gravitation. This paper outlines some of the tests now possible with space techniques that have opened the entire solar system to us as a laboratory for physical experiments.
