.... but since I'm an engineer I have to point out that an MSL drill hole is about 17mm in diameter and 4 cm deep, and the HP3 mole is 27mm in diameter....

Push number three? Sol 250 (Aug 10)
Looks like at lease 2 pushes in different locations during this sol. We can see some crumbling of the pit wall, but due to the late afternoon shadows we can't yet see inside the pit. But progress is progress smile.gif

We can see a bit into the hole. Brightness jacked up, square-root style. There is some soil collapsed around the mole. However, I can't tell if this is progress from the previous status.

Doing something similar with the sol 243 image, I think there is certainly some extra material in the hole on sol 250.

looks a bit better on sol251
https://mars.nasa.gov/insight-raw-images/su...0000_0250M_.JPG
based on the integrity of the hole, it makes sense such a simple pressing action would not fill the hole very much further than it has already collapsed, and even so the resultant infill would be too loose and leave a derth of soil around the probe that would tend to complicate attempts at further compaction, so it would seem the approach requires additional soil followed by compressive pressing.. im sure they've already tried different approaches based on all foreseen contingencies, well see what comes up next.

There were two separate scoop contacts on sol 250, and now two more on sol 253. It looks like the strategy is to press in different locations to encourage material to slump into the hole, though it's not always apparent. The first contact on sol 250 did result in a slump of material into the hole. Whether this is enough, or whether more material will have to be pulled in, is something we will have to wait to see.

Here is the hole after sol 253, brightened to show debris in the hole. A bit more than on sol 250, but not much more.
