Why it is an analog
Has the longest Quaternary basalt flow on Earth, comparable to long lunar mare flows. It scores high on composition (basalt), roughness and slope, has no lunar analog history, and is far from other known sites.
Key differences: where the analogy breaks down
Basalt is alkaline, oxidised; air; vegetation patches.
Experiments done
Volcanology of the longest Quaternary lava flow on Earth; inflation structures and lava tunnels.
Experiments proposed
Lunar mare long-flow and sinuous-rille analog; lava-tube/inflation-pit exploration for lunar skylights; long rover traverses on a single basalt surface; regolith development on young basalt.
How to adjust it
Simulant lanes across the flow surface; seal a lava tunnel section for thermal/radiation logging; night-time cold-soak 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, "atacama salars", is about 1439.8 km away.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 99.8 | 52.1 | 8.6 | In a flagged tile |
| Connecting Ridge C1, Landing and mobility | Scored | 99.5 | 42.5 | 15.9 | In a flagged tile |
| Connecting Ridge C1, Power and night | Scored | 99.8 | 37.9 | 8.6 | In a flagged tile |
| Shackleton rim, Base | Scored | 99.5 | 56.0 | 9.7 | In a flagged tile |
| Shackleton rim, Landing and mobility | Scored | 99.9 | 56.0 | 15.9 | In a flagged tile |
| Shackleton rim, Power and night | Scored | 99.5 | 40.7 | 9.7 | In a flagged tile |
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.
