Abstract [en]

The ExoMars Rover, developed by EADS Astrium to perform in-situ investigations into the potential existence of life on Mars, may also be exploited for use on other planetary bodies. The Icy Moons of Jupiter (JIMs): Europa, Ganymede and Callisto, are in particular also of key interest to astrobiologists and geologists. The purpose of this research was to perform a feasibility analysis on the operation of the ExoMars rover on these Icy Moons. Specifically, this involved the conduction of design/concept study to determine whether it is possible from a thermal and system power point of view with the current design and, if not, what modifications would need to be implemented for successful operation. The European Space Agency standard tool ESATAN-TMS was employed to perform a detailed thermal analysis. Initially the original model as provided by EADS Astrium-UK was simulated in the extreme environment of Jupiter’s icy moons. On the basis of findings, it was determined that alterations were necessary to the passive thermal control and power sub-system. The rover model was updated and then again placed in the environments of icy moons to be analysed over five scenarios encompassing: equatorial and polar regions of both Europa and Ganymede and on equator of Callisto. The results of these missions were post-processed in the advance post processing tool Thermal NV. It was found that major design changes were required as the original rover failed completely to work on JIMs. Key changes implemented were: the reduction of radiator areas, replacement of solar arrays with Multi Mission Radioisotopes Thermoelectric Generators and their accessories. The structural temperature was also found not to compatible with moon’s surface and a redesign of this element is recommended: however, altering the structural design was beyond the scope of this thesis. From the analysis of all defined scenarios, it was concluded that the rover need major changes in structure, power subsystem and slight changes in radiators sizing, Of key significant, however, was the finding that if the modified rover is made suitable for one moon, then it would be able to operate in the environments of all three icy moons. Consequently, it is feasible that following these design changes that the ExoMars rover concept could be employed for the exploration of JIMs, which would have significant scientific value over a range of science missions, findings of life and other geological investigations.
