Shaking managed to un-stick soil sample.
It looks like the attempts to vibrate the Martian soil through the mesh screen into the TEGA oven worked, and Phoenix can begin its multi-day heating of the sample in order to determine what temperatures the soil will release carbon dioxide and water.
It will take about a week to get results, and Phoenix will still have seven other single-use ovens to bake more mars cookies.
Martian life here we come!
btw $100 says its human dna we find.
