Ideal Microhabitats on Mars: The Astrobiological Potential of Polar Dunes
Bibliographic record
Abstract
We briefly summarize the work and results obtained by the Mars Astrobiology Group at Collegium Budapest Institute for Advanced Study during the last 10 years on the Dark Dune Spot–Mars Surface Organism (DDS-MSO) hypothesis. The spots have been discovered by [1]. Proposed explanation for their changes was given by [2]. During our research we fused remote observations (MEX, MGS, MRO) of Mars, collected and analyzed samples of cryptobiotic crust (CBC) from hot and cold deserts on Earth, estimated environmental parameters and used results from Mars chamber tests [3] as well as analysis of microbial communities in the ice of Antarctic desert carried out by other researchers [4,5]. We also used our results and methods to gain insight into the estimation of the astrobiological potential not only for dunes but other surface features on Mars as well. 6. at the end of spring the surface gets dry and the MSOs go into dormant state [11]; 7. annual recurrence of DDS and seepage roughly at the same location [20].

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.
