Abstract
The possibility of a sustained human presence on the Moon is getting closer every day. A prolonged human presence will require the utilization of lunar resources to minimize the transportation of materials from Earth. Aluminum, an abundant, widespread element found in both lunar highlands and mare, offers significant potential for structural and manufacturing applications. However, conventional terrestrial methods such as the Bayer and Hall-Héroult processes are not well suited for lunar implementation due to their environmental and material constraints. This study presents and experimentally validates an alternative lunar-compatible pathway for aluminum production. A lunar highlands simulant (LHS-1), was beneficiated and subsequently leached with hydrochloric acid to refine it to alumina. The refined alumina was electrochemically reduced to aluminum afterwards. The reaction products were analyzed and imaged using a series of analytical techniques. The aluminum produced was ⩾ 99 % pure falling within alloy 1100 standards. The aluminum produced was successfully shaped into a wire spool that can be used for electron beam additive manufacturing on the Moon. The present work shows that the critical steps for a lunar aluminum production chain are feasible. A review of the key operational and material requirements for implementing each stage of the process under lunar conditions is also presented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
