  As space agencies are planning manned missions to reach Mars, researchers
need to pave the way for supporting astronauts during their sojourn. This will
also be achieved by providing broadband and low-latency connectivity through
wireless network infrastructures. In such a framework, we propose a Martian
deployment of a 3-Dimensional (3D) network acting as Cloud Radio Access Network
(C-RAN). The scenario consists, mostly, of unmanned aerial vehicles (UAVs) and
nanosatellites. Thanks to the thin Martian atmosphere, CubeSats can stably
orbit at very-low-altitude. This allows to meet strict delay requirements to
split functions of the baseband processing between drones and CubeSats. The
detailed analytical study, presented in this paper, confirmed the viability of
the proposed 3D architecture, under some constraints and trade-off concerning
the involved Space communication infrastructures, that are discussed in detail.
