This paper has two main objectives: to review the current status of the Martian environmental conditions that impact Martian systems, and to derive from them the top-level requirements for the assembly, integration, and test (AIT) of Martian systems. Each planetary system must be space qualified in order to survive harsh planetary conditions on top of other mission phases like launch, cruise from Earth to the specific celestial body, entry, descent and landing (EDL), and end of operation. In general, Martian systems include three types of landers: long term permanent stations, rovers, and any other landers for long term operation required for unmanned or manned missions. The Martian environmental conditions from the engineering points of view include: temperature variation, radiation environment, Martian gravity, regolith/soil conditions (dust), and Martian geological features, depending on the Martian surface mission profile and their impact on any system operating on Mars for the required time range. Then, top-level AIT requirements for surface Martian systems are developed and presented based on knowledge of Martian environmental conditions. The impact of the most recent Martian landers and orbiters is explained. Future Martian missions are also briefly described. Special attention is given to AIT requirements associated with the thermal variation, radiation environment, Martian atmosphere, and dust. Finally, conclusions and recommendations from a Canadian perspective are also included.
