Why it is an analog
Japan's active lunar test field, with an established industry and university user base.
Key differences: where the analogy breaks down
Rounded humid quartz sand; coastal; temperate.
Experiments done
ispace HAKUTO rover tests (2016-18, incl. night tests under side lighting); Bridgestone lunar tyre tests; SLAM navigation and in-crater communication tests on a 0.5 ha field with flat and 5-20° slope zones.
Experiments proposed
Rover traction on loose sand; crater-wall communications; navigation datasets.
How to adjust it
Fine simulant beds; artificial craters; low-angle lighting rigs for polar-light tests.

v1 score, percentile and overlap flag
A descriptive lookup of scores v1 already stored. It is not a test, and a high percentile here does not show that this is a good analog.
v1 used this site
No. The nearest v1 site, "samoylov", is about 4119.2 km away.

Overlap flag: whether the tile used for the score is one v1 flagged as stable in its top group across the Monte Carlo runs.
What these scores can and cannot tell you
- This is a lookup of scores v1 already stored. It is descriptive and is not a test of the method.
- A site is matched to the best-scoring tile that passed the gates within the match radius. A different radius would give different numbers.
- Tiles are large compared with most sites, so a score describes the surrounding area, not the site itself.
- Scores exist only for tiles that passed the land-cover and data gates. A gated-out or unscored site has no score, which says nothing about how good an analog it is.
- Percentile is the share of scored tiles in that view with a lower score.
- The Moon score is effectively terrain only. Mars is a low-confidence secondary result.
- v1 failed its negative controls, so a high percentile here does not show that a site is a good analog.
- The ranking is not checked against independent data. Gravity, air, dust and radiation are not scored.
- Sites are compared with views of their own body only.
- Match radius: 20 km, the radius v1 used.
