PARCS
- Primary Atomic Reference Clock in Space
PARCS is an atomic-clock mission scheduled to fly on the International
Space Station (ISS) in early 2005. The mission, funded by NASA and including
NIST as a partner, involves a laser-cooled cesium atomic clock, a high
stability hydrogen-maser oscillator, and a time-transfer system using
Global Positioning System (GPS) satellites. The objectives of the mission
are to:
Test
gravitational theory
Study laser-cooled atoms in microgravity
Improve the accuracy of timekeeping on earth
