MSTAR: Testing lorentz invariance in space using high performance optical frequency references

The proposed mini SpaceTime Asymmetry Research (mSTAR) satellite mission will perform a test of special relativity. By comparing an absolute to a length based frequency reference, a Kennedy-Thorndike (KT) type experiment is carried out testing the boost dependency of the speed of light using the large velocity modulation in low Earth orbit (LEO). Using clocks with instabilities below the 10
