Can you dig it? Sol 24 trench widening.


Looks like a nice chunk of white stuff has been excavated into the lower pile of debris.

Color shot of the work area and scoop:



There definitely is some differently colored soil down there. At least more gray than the rest, possibly bluish-greenish after all.

Dan, I think you've mistaken a part of sunlit soil in Phil's image as white stuff.

Loving this new trench...!

Q: just wondering... was this 'scratch' caused by the rasp?

To me, it looks like the tool has scraped across a flat hard surface...

Perhaps you were on to something - from Lemmon's directory:

I spent over an hour attempting to fill in the 3 gaps in the stereo image released this morning, only to have Phoenix downlink a better version soon after. Anyway, here is the exercise in futility:

I wonder why a greater percentage of images than usual are suffering from data loss in transit. Is this a Phoenix, Odyssey, MRO, or DSN problem?

There is just a 3x2 section to complete the horizon pan, the actual horizon bit (3x1) was taken on sol 22 but I believe lost due to the anomaly. Four pointings of the near field were also taken and downlinked on sol 21. I suspect we'll get most of the remaining data with the 'most-data-rich-sol-ever' going on tosol as a result of the anomaly.

Awesome!

It's probably the link between Phoenix and Odyssey. While there is a automatic re-transmission protocol (Go-back N per CCSDS Proximity standards), there was a implementation "feature" (error) where in some rare occassions some packets are dropped. Same happens between the MERs and Odyssey, since the UHF radio is the same. Drop-out can also happen between Orbiter and Earth if the signal-to-noise ratio drops below threshold (too much rain, wind, mispoint, eats all the margin) but this happens much less frequently.

Due to the Flash anomaly, they've added extra UHF passes. Perhaps some of these extra passes are less than optimal (low elevation etc.).

I've made a sol-by-sol comparison of the Dodo-Goldilocks area showing surface activities. Some of the images are fudged a bit, but it gives the idea.

Man, I really think this discovery, or rather confirmation, demands a new thread, something entitled "it IS ice"...


Agreed, moved posts to Water Ice Confirmed!

Using Phil's side-by-side comparison, here is the first and only definitive sol 5-20 über-animation (of doom).
