Abstract
Abstract High‐resolution images and elevation data sets from the Lunar Reconnaissance Orbiter along with spectral data from the Clementine mission are used to identify and map in detail the well‐preserved Late Imbrian Tsiolkovskiy crater situated on the far side of the Moon. This study identifies five distinct morphologic units associated with Tsiolkovskiy crater and the surrounding ejecta blanket. Analysis of the spatial and stratigraphic relationships of each of the ejecta units shows an asymmetrical distribution of the overall ejecta blanket, as well as a consistent overprinting of ballistic ejecta by ponds and flows of impact melt‐bearing material. This study shows that the asymmetric distribution of the ejecta blanket, including a distinct up‐range “forbidden zone,” is related to the impact direction and angle for the impactor that formed Tsiolkovskiy crater. The consistent presence of melt‐bearing ponds and flows overlying the ballistic ejecta deposits indicates that two separate ejecta emplacement events occurred. We interpret this as an initial phase of ballistic ejecta emplacement during the excavation stage, followed by a second phase of melt‐bearing ejecta emplacement. The second phase begins during the end of the excavation stage and continues throughout and beyond the modification stage of crater formation.

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
