PARCS advances through NASA reviews. (News Briefs).


The NIST-led program entitled Primary Atomic Reference Clock in Space The Primary Atomic Reference Clock in Space or PARCS is an atomic-clock mission scheduled to fly on the International Space Station (ISS) in 2008. The mission, funded by NASA, involves a laser-cooled caesium atomic clock, and a time-transfer system using Global Positioning  (PARCS PARCS Primary Atomic Reference Clock in Space

) has successfully completed its second NASA review, the requirements definition review. This review, which included both a science panel and an engineering panel, considered both the scientific merits of the mission and the technical feasibility of the proposed experiments. This was the final review of the science. A series of additional reviews also address engineering issues of the flight systems.

In its report to NASA, the review panel recommended that "the PARCS project should proceed with all possible speed and deliberation toward the preliminary design review." The complete preliminary design of the system will be considered in the next review, which is scheduled for late summer.

The objectives are to test certain aspects of relativity theory, to improve upon the realization of the second, to study the performance of GPS clocks, and to study the dynamics of atoms in microgravity.
