Key Finding
Systematic LOLA Polar Illumination Baseline
First LOLA-based polar illumination maps. Shackleton rim identified as prime high-illumination zone. Topographic horizon masking drives solar availability at poles.
Key Finding
95.65% Illumination at 10 m Elevation
95.65% illumination achieved at 10 m above ground level using 20 m/pixel LOLA DTM. Mast elevation significantly improves solar capture at crater rim sites.
Key Finding
18.6-Year Precessional Cycle Validation
18.6-year lunar precessional cycle governs long-term illumination variation. Shackleton rim remains consistently high across the full cycle.
Key Finding
5 m/pixel DEM, ±0.30–0.50 m RMS Accuracy
5 m/pixel DEM with RMS height uncertainty 0.30–0.50 m — the highest resolution publicly available LOLA product.
Key Finding
94% Annual Illumination (Shackleton Rim)
LROC WAC image-based validation: Shackleton crater rim illuminated for ~94% of a lunar year from direct optical imagery.
Key Finding
92% Solar vs. 51% DTE Decoupling
Best South Pole site achieves 92% solar illumination but only 51% DTE visibility. Solar and DTE availability are decoupled.
Key Finding
3-Parameter Combined Site Scoring (ESA)
ESA lander study combining illumination, communications, and terrain slope in a multi-parameter framework.
Key Finding
Coverage 1550–2650 CE, Sub-Arcsecond Accuracy
DE440/DE441 ephemeris covers 1550–2650 CE with sub-arcsecond accuracy. Primary planetary kinematics dataset for modern spaceflight.
Key Finding
38 K Minimum Temperature Floor
PSR cold trap minimum temperature = 38 K (−235 °C). Among the coldest stable surfaces in the Solar System.
Key Finding
250 Billion Measurements, 0.5°/0.25 hr Resolution
250 billion calibrated Diviner measurements; 0.5° spatial resolution and 0.25 hr local-time resolution thermal model.
Key Finding
40,000 km² Total Micro Cold Trap Area
Micro cold traps exist at 1 cm–1 km scales; total estimated area ≈ 40,000 km². More abundant than large PSRs.
Key Finding
0.71 Illumination Fraction; 73–117 hr Battery Need
Shackleton rim average illumination fraction = 0.71; battery storage required = 73–117 hr depending on lander base load.
Key Finding
Independent JAXA/KAGUYA Altimetry Validation
KAGUYA LALT altimeter independently validates polar illumination zones without relying on LOLA — an independent JAXA cross-check.
Key Finding
7-Year LOLA Mission Summary (Provenance Standard)
Comprehensive 7-year LOLA mission summary validating all LOLA-derived terrain products. Gold-standard LOLA data provenance citation.
Key Finding
11 ROIs, 3-Criteria GIS Spatial Selection
11 ROIs evaluated using GIS multi-criteria: temperature <110 K, slope <20°, H₂O >100 ppm. Demonstrates multi-parameter South Pole site selection.
SelenSync Academic Positioning
SelenSync is the first web platform unifying terrain illumination (LOLA), DTE link budget (3 DSN complexes), cryogenic thermal survival (Diviner), techno-economic modeling, real-time DE440 ephemeris, and 4 CLPS commercial lander profiles within an integrated decision-support environment — building directly upon the multi-criteria frameworks of Koebel et al. (2012) and Flahaut et al. (2020).
