Sending a rover to the moon is an exciting event, but first, the design must be thoroughly evaluated. Within every engineering design process, no matter on which scale, review is required to ensure functionality and to point out errors, or minor details, that could potentially lead to failure of the whole design. The Preliminary Design Review (PDR) is a multi-disciplined technical review to ensure that the Lunar Zebro can proceed its way to the fabrication of the test model and that it can meet all performance requirements within cost, schedule, and risk.

The PDR structure splits up into the various subsystems, who have been documenting the progress of the project in the last months. The documentation was sent to reviewers who attended the presentations during the PDR week, given by the team members of the corresponding subsystems. The reviewers are experts in the field, both internal from the TU Delft faculty and external from our partners. They are tough and professional and the students have less experience, which makes the PDR both challenging and insightful. It was a lesson in explaining your design works to the experts.

The reviewers gave detailed suggestions that the books do not tell you but come from experience. Their feedback will be taken into account to advance to the Test Readiness Review and the building of the test model.
