For the accomplished earth demonstration scenario, the Shakelton crater at the lunar south pole is taken as reference. In the areas of permanent darkness within this crater, samples of scientific interest are

The space segment comprises of up to 4 S/C swarms each consisting of up to 6 nano satellites (NanoProbes) and 1 mother spacecraft (MSC) to be launched with a single launcher in polar low Earth orbits. The NanoProbes, equipped with magnetometer payloads operate in the vicinity of the MSCs. The MSCs will eject the NPs after acquisition of the initial orbits, provide control and maintenance of the swarm constellation and serve as communication relay to the ground. The systems design relies on near to medium term technology.

The polar terrain is located at the rim of the Aitken Basin, being the largest impact crater in the solar system, where material from the lunar mantle has been ejected to the surface. This basin features a diameter of 2,500 km and variations in altitude as large as 14 km. Since the solar elevation never exceeds 1.5 at the pole, there exist mountain peaks in this area that are characterised by near eternal illumination. These summits provide a benign thermal environment for any long-term robotic or manned lander mission, and ideal conditions for photovoltaic power generation. The smaller impact craters in the polar region, on the other hand, possess depths with constant darkness. These craters are evidently harbouring water resources that remain conserved through the cryogenic temperatures inside them. The ice originates from the bombardment of comets throughout the billions of years after the formation of the lunar crust. For this terrain updated analyses of the solar illumination and ground station visibility conditions have been performed. These are based on the refined lunar digital elevation model provided by the Japanese Kaguya/Selene mission, originating from its LASER altimeter instrument. The resulting maps for the South polar region will be presented in this paper. Some considerations on the geology of interesting locations within the SPA are complemented. With these prerequisites, several possible landing sites for a future lunar mission have been selected. A detailed analysis of illumination timelines will be presented for these sites.

The first is technology demonstration for enabling technologies like propulsion-based soft precision landing for future planetary landing missions. This involves also enabling technology experiments, like fuel cell, life science and life support, which are embedded in the stationary payload of the lander. The second main and equally important aspect is the in-situ investigation of the surface of the Moon at the lunar South Pole by stationary payload inside the Lander, deployable payload to be placed in the vicinity of the lander and mobile payload carried by a rover. The currently assessed model payload includes 15 instruments on the lander and additional five on the rover. They are addressing the fields geophysics, geochemistry, geology and radio astronomy preparation. The mission is currently under investigation in frame of a phase A mission stud...
