Abstract

The Space-Time Explorer and Quantum Equivalence Principle Space Test (STE-QUEST) mission is devoted to test Einstein’s Theories of Special and General Relativity using an atomic optical clock and a differential dual-species atom interferometer operated in a highly elliptical Earth orbit. As science objectives, STE-QUEST will measure the Earth gravitational redshift with a fractional uncertainty of 10-7, the Sun gravitational redshift with a fractional uncertainty of 2⋅10-6 and the Weak Equivalence Principle by testing the universality of free propagation of matter waves with an uncertainty of 1⋅10-15 in terms of Eötvös parameter.
