The PARCS (Primary Atomic Reference Clock in Space) mission is designed, not only to perform certain tests of relativity theory, but also to demonstrate space-clock technology that may prove useful as an international standard of frequency and time and for space exploration of the Moon and beyond. After a short review of the project, this paper presents a brief description of the considerations that have led to the specific design parameters chosen for the PARCS mission.
