Why it is an analog
Only simple crater in flood basalt; also a crater-lake analog.
Key differences: where the analogy breaks down
Lake, forest and farms (fails GSOP gates); humid monsoon.
Experiments done
Shocked basalt (maskelynite), impact-melt and post-impact alteration studies; comparisons with Martian craters in basalt; ISRO/PRL spectral work.
Experiments proposed
Impact-generated clays and carbonates in basalt; ejecta-alteration spectroscopy; crater-lake sediment cores as a paleolake analog (like Jezero).
How to adjust it
Rim ejecta plots and dry-season shoreline cores only.

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
Yes. This place matches the v1 site "lonar", about 0.5 km away.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Jezero, Base | Gated outevery tile in range failed a land-cover gate; most common: vegetated | not provided | not provided | not provided | not provided |
| Jezero, Ice resources | Gated outevery tile in range failed a land-cover gate; most common: vegetated | not provided | not provided | not provided | not provided |
| Jezero, Landing and mobility | Gated outevery tile in range failed a land-cover gate; most common: vegetated | not provided | not provided | not provided | not provided |
| Jezero, Power and night | Gated outevery tile in range failed a land-cover gate; most common: vegetated | not provided | not provided | not provided | not provided |
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.
