ASTRIUMSystem Approach

Baseline Assumptions:• Launcher Ariane5 ECA • Lander based on ATV technology

and similar projects


ASTRIUMSystem Aspects: Lunar Far Side

• Primary landing site on lunar far side:- Deadalus crater at 179° E, 5° S

93 km

• Best shielding from terrestrial RF spillage

• Best shielding from solar RF bursts at lunar night


ASTRIUMSystem Aspects: Payload Data Transfer (1)

• High data rate to be transferred from lunar far side to earth via data relay satellite

• Propose to use one data relay satellite DRS in halo orbit aroundL2 of Earth/Moon System

• EMI considerations suggest optical link to DRS, Ka-band link to earth GS (baud rate ≥ 100 Mbit/s)

ASTRIUMConclusion

Within the LIFE scenario, the Lunar Lander is a very challengingproject:

• With todays technology, only RTGs can fulfill the power require-ments during lunar night – the power demand is a serious challenge (considering the RTG procurement problems)

• It is therefore proposed to refrain from night time operations• The data transfer requirements and the unique location on lunar

far side necessitate additional infrastructural elements (e. g. optical laser link, data relay satellites)

• Compared to the above, the remaining technical challenges can be covered with moderate development effort
