Looks like the Sol 12 images are coming down
http://phoenix.lpl.arizona.edu/images.php?...3286&cID=50 Motion in the scoop for sure, so hopefully a full delivery will be imaged...in full. |

These two are from the same filter (RC, right blue) from sols 9 and 13:

I don't see any difference that isn't explained by phase angle effects. Here's a flicker gif between sol 12 (lower sun elevation) and sol 13 (more overhead). The regolith is strongly backscattering, while the mystery stuff is less phase angle dependant, suggesting non-powdery (crystalline?) makeup.

The regolith is strongly backscattering, while the mystery stuff is less phase angle dependant, suggesting non-powdery (crystalline?) makeup. Indeed, there's no evidence for a temporal change in the white material (sublimation or whatever), but those phase effects are certainly interesting! I don't think we saw this kind of behaviour for any white material dug up by Spirit! Thanks for this image, Gordan. |
