I've been pursuing some writing and planning projects today so didn't have time to post much. However I wanted to note that the Phoenix team appears to have attempted today the difficult operation of squeezing a sample into the barely-open doors of TEGA oven 5. They have in the past expressed confidence that they could get something inside, and it now appears they were confident enough to try. We're looking at TEGA from the mast-mounted camera; oven 5 is on the opposite side of the TEGA "rooftop" from SSI, so it's not a good view of the oven door, but you can see a lot of soil piled up at the roof peak, which would be near the widest part of the oven door gap.
As a reminder, here's a "before" picture of the door opening attempt. This one was taken by the robotic arm camera, looking down on the sloping "rooftop" of TEGA.
