The aim of this paper is to present the concept of a dedicated gravity field mission for the
planet Mars, the Mars Quantum Gravity Mission (MaQuIs). The mission is targeted at
improving the data on the gravitational field of Mars, enabling studies on planetary
dynamics, seasonal changes, and subsurface water reservoirs. MaQuIs follows well known
mission scenarios, currently deployed for Earth, and includes state-of-the-art quantum
technologies to enhance the gained scientific signal.
