This paper describes work aimed at producing a “Primary Atomic Reference Clock in Space (PARCS),” scheduled for flight on the International Space Station in 2004. The microgravity environment of space will allow this clock to achieve an uncertainty ten times lower than can be achieved on earth. The experimental objectives are to measure several relativistic effects on clocks and to provide both time and frequency references available as an international standards accessible to anyone on earth. © 2000 American Institute of Physics.
