Technology Development for Space Time Asymmetry Research (STAR) Mission

摘要: The Space Time Asymmetry Research (STAR), recently proposed as a NASA Small Explorer Mission (SMEX) will test isotropy and symmetry of space time at unprecedented precision. We use precision molecular iodine stabilized Nd:YAG laser interferometers to search for small deviations from Lorentz Invariance, cornerstone relativity particle physics thus our understanding the Universe. A violation would have profound implications cosmology physics. An improved null result constrain theories attempting unite gravity. previously submitted Science White Paper Astro 2010. While self contained, this mainly outlines technology development STAR mission, with emphasis on science payload spacecraft. With funding level compatible SMEX, we plan develop high performance, reliability in 4~5 year frame. mission is designed work one-year space, possible extension indefinitely longer long remains functional.
