The accelerating expansion of the universe and galaxy rotation curves, which are described by dark energy and dark matter, could be related to a modification of gravity on large scales. As ground-based tests of Newtonian inverse square law of gravity are affected by the Earth gravity and terrestrial noise, it is essential to perform these experiments in spaceborne laboratories using drive and test masses isolated from any terrestrial and seismic noise. In-situ micro-gravity measurements of the inverse square law will help us comprehend better gravitational phenomena at different scales.
