Tardigrade Exposure to Outer Space Conditions - An Experimental Validation
Bibliographic record
Abstract
Researchers have identified and used regions characterized by extreme environmental conditions on Earth as analogue sites for conducting astrobiological experiments. Researchers also have simulated extreme environmental conditions in laboratory settings. Whether data obtained at analogue sites or in laboratory settings would be similar to data obtained extraterrestrially is unknown because opportunities for comparison occur very rarely. We realized such an opportunity by replicating a 'bioexposure' experiment that was conducted recently in Earth orbit. Tardigrades (Phylum Tardigrada -extreme-tolerant, microscopic invertebrate animals) exposed to desiccation and radiation treatment combinations in a laboratory setting yielded survivorship curves similar to survivorship curves yielded in 2007 by Tardigrades exposed to outer space conditions in the BIOPAN facility aboard the FOTON-M3 spacecraft. This constitutes the first direct comparison demonstrating that data acquired extraterrestrially can be replicated in a laboratory setting on Earth, validating Earth-based, laboratory setting research.

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.
