<strong>Final</strong>ly, in Figure 4.5-3 the side panels of the spacecraft body are folded away such that the internal<br />
arrangement of equipment becomes visible.<br />
All equipment is spread over the North panel (on the left) and the South panel (on the right). These are<br />
the preferred locations since the conditions for heat rejection are optimum there which is beneficial for<br />
the sizing of the thermal control system. Since the available mounting surface of these panels is<br />
comfortable also in view of a later optimisation of the spacecraft balancing, no equipment needs to be<br />
mounted on the East and West panels. Hence, the East and West panels are designed as light weight<br />
closure panels.<br />
As a conclusion it can be stated that for the overall spacecraft configuration no major criticality has<br />
been identified. All design concepts applied are based on heritage thus providing a solution with low<br />
risk.<br />
