The mSTAR instrument will investigate a fundamental assumption of physics by searching for variations in the speed of light as a function of velocity of the reference frame. The discovery of such dependencies would revolutionize physics, our understanding of how the Universe began and have profound implications for astrophysics, Special Relativity and the Standard Model that describes the physics of matter and energy.More »

This experiment is designed to assess the mass gauging resolution of a novel implementation of experimental modal analysis (EMA). The central objectives of the MPG experiment are to (1) record the modal response of a model propellant tank at different fill-levels under unsettled, microgravity conditions, and (2) record the modal response of the propellant tank during simulated propellant transfer. Phase II utilized a full-fidelity propellant tank with flight heritage, extending the gauging analysis to accommodate changes in tank pressure during low-gravity propellant transfer operations. The technology is expected to impact commercial and military satellite providers, NASA's human spaceflight program, and commercial launch service providers in addition to NASA programs developing on-orbit fuel depots.
