One important aspect of future missions to ice-covered moons within our solar system is the exploration of the oceans underneath the ice. Based on the exploration concept developed in the Europa-Explorer project, the aim of the EurEx-LUNa project is to further evolve the under-ice navigation and exploration capabilities of an autonomous system and subsequently evaluate them in an analog mission. In order to allow for persistent exploration in challenging and difficult to access environments, both the software and the hardware of an autonomous underwater vehicle must be thoroughly tested and continuously improved. An essential part is the safe return of the underwater vehicle and to successfully attach to the docking interface, allowing data and energy exchange. To evaluate the capabilities and robustness of the overall system an analog mission will be carried out in an ice-covered lake.

Schematic overview of a possible mission scenario. 0) ice-drill penetrated the ice-shield. 1) AUV has been released from the payload compartment. 2) AUV descends to ocean floor. 3) exploration using cameras/sonar and internal sensors. 4) ascend to the ice/water boundary. 5) return to ice-drill (using autonomous localization buoys) and docking for energy/data exchange.
