O_o if the ice is breaking up like that, what are the odds of scooping some of it up?
Ice cream, straight of the freezer, is hard to scoop up, but leave it out a while and it gets warmer and easier to carve into. (perhaps not the best of analogies, lolol, I don't even like ice cream). Is it's position under the lander going to make acquiring it difficult/impossible? Or would you not want to anyway for reasons of contamination when Phoenix landed? -------------------- -- Hungry4info (Sirius_Alpha)

I hope that Happy Pan will be significantly better than Peter Pan.
At last we have perfectly focused image of the horizon. Sol 73 SSI LEFT, filter unknown (probably 2), Az: 96 (E) Let's compare with out of focus image (Peter Pan). Sol 28 SSI RIGHT, filter 1, Az: 96 (E) -------------------- Free software for planetary science (including Cassini Image Viewer).

That's not a focus issue, rather a raw contrast stretch issue.

It is a focus issue, different filters have different focus
 . The SSI is probably optimised for the blue filter's focus, as are pancams on MERs.-------------------- Antti Kuosmanen

The diopters are optimized for near field studies (i.e. on the s/c deck), most others have good focus at distances such as this. It looks more to me like different filters and illumination angles than anything else.

Could be higher wavelett compression too, resulting in a softer image. The second image is clearly softer though, regardless of any illumination issues.

SSI focus is optimized for 3 to 3.5 m distance, since the main role for SSI is support of digging ops, and it has no role in picking where to drive next. It is still good at the horizon, but not ideal. Sampling is best in the red stereo filters. As with Pancam, the blue filters look sharper, but that is due to aliasing. Super sharp is good for pretty pictures; good sampling is important for good stereo models even if it looks slightly less sharp.
And the new pan better end up higher quality--it costs 10x as much. |

Some new extensions to Cupboard now. They've messed up poor old Dodo-Goldilocks a bit.

The new pan was sized to take to Nov 15, with various assumptions about available passes and competing priorities. That didn't include retakes of unrecoverable missing data, but there's a lot of slop in the estimate.

Couple of new 3Ds in my Phoenixpics gallery now, if anyone wants a look... Those dirt dumps really are starting to look like moden art now...

The Cupboard trench is getting bigger:
