Raman characterization of terrestrial analogs from the AMADEE‐18 astronaut simulated mission using the ExoMars RLS simulator: Implications for Mars
Bibliographic record
Abstract
Abstract Between February 1 and February 28, 2018, the Austrian Space Forum, in cooperation with research teams from 25 nations, conducted the AMADEE‐18 mission—a human‐robotic Mars expedition simulation in the Dhofar region in the Sultanate of Oman. As a part of the AMADEE‐18 simulated Mars human exploration mission, the Remote Science Support team investigated the Dhofar area (Oman) to qualify it as a potential Mars analog site. The motivation of this research was to study and register selected samples collected by the analog astronauts during the AMADEE‐18 mission with the European Space Agency (ESA) ExoMars Raman Laser Spectrometer (RLS) simulator, compare the results with standard laboratory measurements, and establish the implication of the results to the future ESA ExoMars mission. The Raman measurements identified minerals such as carbonates (calcite and dolomite), feldspar and plagioclase (albite, anorthite, orthoclase, and sanidine), Fe‐oxides (goethite, hematite, and magnetite), and Ti‐oxide (anatase), each relevant to planetary exploration. As we have presented here, Raman spectroscopy is a powerful tool for detecting the presence of organic molecules, particularly by analyzing the principal vibration of CC and CH bonds. It has also been shown that portable Raman spectroscopy is a relevant tool for in situ field studies such as those conducted during extra‐vehicular activities (EVA) in simulated missions like the AMADEE‐18 and the future AMADEE‐2020 campaign.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
