Why it is an analog

India's composition analog for lunar highlands.

Key differences: where the analogy breaks down

Vegetation and humidity; Archaean metamorphic rock, not lunar ferroan anorthosite.

Experiments done

Anorthosite quarried to make ISRO's lunar highland soil simulant (LSS) used for Chandrayaan-2/3 lander-leg and rover-wheel tests; petrology by GSI and universities.

Experiments proposed

Highland-composition reference spectra; simulant production; drill tests in anorthosite.

How to adjust it

Quarry-floor test pads; crushed-rock simulant beds next to the source outcrop.

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 981.7 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.
