An Introduction to Assembly Integration and Test (AIT) Requirements for Martian Systems
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
