Tides on Earth have a far-reaching influence, including disturbing satellites' measurements by affecting their motion. The LAser RElativity Satellite (LARES), is the best ever relevant test particle to move in the Earth's gravitational field. In a new study, LARES proves its efficiency for high-precision probing of General Relativity and fundamental physics.
