Why it is an analog
Best-preserved simple impact crater on Earth and the classic Apollo training site; strong terrain match.
Key differences: where the analogy breaks down
Target rocks are sandstone/limestone, not anorthosite or basalt; eroded and weathered; mid-latitude sun; no permafrost.
Experiments done
Apollo crew geology training on ejecta stratigraphy and inverted rim sequences; Shoemaker's crater-mechanics mapping used to read lunar craters; NASA Desert RATS suit and rover trials (late 1990s-2000s); shock-metamorphism studies (coesite, stishovite).
Experiments proposed
Artemis EVA traverse rehearsal on blocky ejecta; ground-penetrating radar of breccia lens; regolith-mechanics tests on fine rim debris; lander hazard-detection LiDAR on rim boulders; sample-triage drills (which clasts to bag).
How to adjust it
Spread a few hectares of basaltic/anorthositic simulant on the rim to match regolith; use night-time ops with a single low-angle floodlight to mimic polar lighting; shade a crater-wall alcove with insulated covers to create a cold-trap test bay.

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
Unknown. The nearest v1 site, "sf volcanic field", is about 56.3 km away, and the files cannot say whether v1 meant the same place.
| Score view | Result | Percentile | Score | Distance to tile (km) | Overlap flag |
|---|---|---|---|---|---|
| Connecting Ridge C1, Base | Scored | 66.6 | 1.3 | 15.5 | Not in a flagged tile |
| Connecting Ridge C1, Landing and mobility | Scored | 71.2 | 1.0 | 15.5 | Not in a flagged tile |
| Connecting Ridge C1, Power and night | Scored | 66.6 | 0.9 | 15.5 | Not in a flagged tile |
| Shackleton rim, Base | Scored | 78.5 | 28.9 | 15.5 | Not in a flagged tile |
| Shackleton rim, Landing and mobility | Scored | 86.0 | 33.1 | 15.5 | Not in a flagged tile |
| Shackleton rim, Power and night | Scored | 78.5 | 21.0 | 15.5 | Not 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.
