Phoenix Oven Doors - Sol 25

The saga with the Oven (TEGA) doors continues.

As can be seen from the image above Phoenix is trying to open the next oven door - and it looks like it is having a problem doing so. The door to Oven 3 is only partially opened - probably as a result of all the soil that remains on the partially open door to Oven 4 - see earlier posts on this one.

What is also interesting is how far the soil has slipped on Oven 4. The image below is the one taken when the problem with the soil on Oven 4 became apparent

I think this soil is like dried mud - stiff and brittle. The water that was present in it when it was dumped on the oven door has all 'evaporated' away now leaving it hard, "dry", and brittle. I think they should get the robotic arm to tap the TESA structure on its side to remove this crud...

The Phoenix team are also having another look at the rock with the hole in it under the lander, this time from a slightly different angle. I still can't see any sublimation on it, but the change in angle doesn't help.

However there is an interesting object on the right of the picture...

Is that something else that has fallen off Phoenix?

Or perhaps it is a seashell
