Description
The Space Time Explorer and QUantum Equivalence principle Space Test (STE-QUEST) is a M-class mission proposal that has recently been submitted to the M7 call in ESA's science program. This proposal has successfully passed the phase 1 selection and is currently under investigation for the phase 2. STE-QUEST will provide an atom interferometric measurement of the universality of free fall in space by measuring the differential acceleration between Rb and K atoms. It will reach the impressive level of 10^-17 in measuring the Etovos parameter, improving by 2 orders of magnitude the most recent results provided by the MICROSCOPE space-mission. In this presentation, I will present the principles of the STE-QUEST measurement, the main characteristic of the mission and discuss the main scientific expected outcome.
