Terraluna: Scale-Resolved Terrain Fingerprints for Earth Analogs of Lunar and Martian Sites, with a Benchmark of a Physics-Informed Encoder

Abstract (excerpt)

We compare the terrain of Connecting Ridge, one of the candidate Artemis III landing regions that NASA announced near the lunar south pole, and of two Martian sites, Jezero crater and Arcadia Planitia, with Earth surfaces, using elevation data alone. A deterministic fingerprint of relief and texture, the structure function ν(L) at hectometre lags and its Hurst exponent, ranks 71 Earth windows from two declared regions for each target, and the same code computes it in Python and in a browser within stated numerical tolerances. …
