They certainly got some serious rasping done:

Awesome! All that's missing is this. (4 MB, but worth it smile.gif )

Is it just me, or did they completely miss the oven? There's no obvious sign of sample on the mesh screen, just on the adjacent closed doors.

I don't think they missed it. There's some material visible on the bottom edge of the mesh as well. The thing is this was nowhere near as much material as the first TEGA delivery so I'm not completely surprised nothing is seen on the mesh. Not completely, but still somewhat surprised not a single particle was stuck at the mesh...

Looking at the early and late post dump shots htere doesn't seem to be much subliming although it is hard to see as the lighting is different between the 0740ish shot and the 1300ish shot

I venture they got an oven-full signal. Maybe.

There is a TEGA post-delivery image that shows soil on the adjacent door, at 0749:

There is an image of soil remaining in the scoop, at 0755, after the above:
http://phoenix.lpl.arizona.edu/images.php?...109&cID=179

I think it's likely that the programmed sequence was to sprinkle until oven-full was detected. That would leave some soil in the scoop. (But, I suppose it's possible that they sprinkled, imaged, sprinkled, imaged without regard to stopping upon oven-full, and that might lead to the same pictures.)

Could be a good sign. The sample went straight through the mesh?

I take it back - there are traces along the lower part of the right-hand door's hinge line, but much clearer dustings on the bottom part of the left-hand door - they're only clear in the RAC images I think.

Still... I would welcome a confirmation of "oven full" from one of our members-in-the-know.

I wonder if it sublimated between rasp/scoop and drop, or if they just didn't get enough out of the rasping?

Neither -- "much of the soil remained lodged in the robotic arm's scoop after the attempt to deliver the sample to the TEGA. "

See http://planetary.s3.amazonaws.com/data/pho...9_16B80MDM1.jpg, which was taken at 07:55, which was after the dumping (which happened some time between 07:33 and 07:49).

As the press release says "the robotic arm collected a more than adequate amount of icy soil", but most of it stuck to the back of the scoop.

Sounds like a pretty easy problem to fix, but then this is Mars.
