In the course of an investigation with EADS Astrium concerning operational boundary conditions and transportation system requirements of future European Lunar robotic missions, the essential infrastructure elements were identified that would be required for ensuring a stepwise built-up of scientific payloads on the Lunar surface and their subsequent operations. Since only European infrastructure elements should be considered for the first phase, an ATV-based lunar lander was chosen as basis for payload transport to the lunar surface. It shall be launched with an Ariane and be capable of transporting a payload of up to 1.7 Mg to the lunar surface. The estimated time frame for the missions was set to 2015-2020. In order to fulfill the demanding requirements of automated robotic missions in terms of mobility, power supply and communications, the basic configuration of the lunar lander concept was adapted and extended for a diversity of applications. Complementary to the various types of lunar landers further mission elements were identified in order to carry out tasks in lunar orbit or at Lagrange point L2 of the system Earth-Moon. During conceptual design of mission scenarios these had to include specific conditions of the landing site, such as the local lunar topography or the light-shadow phases that result from the location. Due to their particular qualities the Lunar South Pole and Lunar Far Side were pre-selected as suitable landing sites. Two different scenarios were hence investigated. For the first one, the Lunar South Pole was suggested as initial landing site, with the lunar infrastructure extending towards Lunar Far Side. Energy production was to be based on solar power. The second one is based on Lunar Far Side as initial landing site followed by stepwise expansion of the infrastructure. Corresponding to the significantly different conditions at Lunar South Pole this scenario shall rely on nuclear power. The most important mission elements will be presented against the background of their range of application as well as their operational requirements.
