Why it is an analog
Accessible Indian jarosite (acid-sulfate) site.
Key differences: where the analogy breaks down
Hot; monsoon rains; scrub and salt-marsh nearby (Rann).
Experiments done
Jarosite-bearing deposits in altered rocks of Kutch characterised as Mars analog (Bhattacharya et al. 2016); Indian Mars analog studies.
Experiments proposed
Spectroscopy vs CRISM jarosite; alteration pathways in basaltic-volcaniclastic rocks; Indian instrument tests.
How to adjust it
Cleared plots on jarosite beds; dry-season ops.

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, "lonar", is about 872.8 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.
