Checking the two Sol dates, 264 and 280 for changes in the details of the grapple fingers shows no appreciable difference between the droplets or clumps on the angled sunlit fingers. The directly lighted side facing right facing finger is not showing the droplets.
3X and DPI 1647,

Perhaps there is a reason for the lack of textured droplet formation on the particular finger?

Details in the prior posted image were not visible, and they are important to understanding the difference between static or active formation of the clumps or droplets on the grapple fingers. They have been repeatedly imaging the fingers in a relatively fixed angle of incidence to the camera, and it can show daily changes in the timing and material nature of the shadowed droplet shapes.
The image here is at 3X and has been altered three times to show that the highlights of the sun facing finger surface has no droplets in appearance. I will produce another image set to compare the multiple images over time using better highlight control as the angle of sun may be suppressing the view of the three dimensional objects.
Here the two sets of red outlined alterations show the face and separately the margins between the upper finger and sun facing finger. There are some droplet shapes between the fingers in the smaller red box. It appears there are no drops between the lower edge of the sunlit finger and the bottom finger. Is that a ground facing edge showing heat rising or a physical cause related to the use of the fingers, or, possibly another reason?

A closeup of the droplets running across the face of a finger from Sol 268 at 3X.

The placement of the InSIGHT lander along a formerly active volcanic linear formation and near the MSL Curiosity location was carefully planned. It was expected that the results would show whether the primary geological structures were heated and active below the surface.
The diamond in red is the InSIGHT location.
The map is a capture of the Google map service from the HiRISE catalog reference site page, with the pattern applied by myself after some alteration.

Paused for the passage of Mars across the Sun, with a DLR post available as an update.

Nice imaged Dana.

Insight in July, 2019, about the timing of the DLR blog entry.

https://www.uahirise.org/ESP_060695_1845

The weather report is incoming once again.

https://mars.nasa.gov/insight/weather/

Lows at night are dipping below -150 F regularly, with 40 MPH winds daily.

The Sol 288 image shows the medium sized rock in front of the lander in full daylight, catching it at just the correct timing to avoid the routine shade.

Now at Sol 290, what will the best approach be for further attempts at the experiment in drilling by a new technique?

Reading your comment to me late here, some day I'll learn the best techniques for dew and highlight tones but for the time being I have to use simple techniques and available software. If Horton were here he could give me some advice on items like Image J which I couldn't use on the light tech laptops I've been using the past few years.
The HiRISE is at such a high altitude and lighting less than on Earth, and, there are probably other reasons the the viewing of landers is difficult on Mars.
The next lander/rovers should be advancements beyond the current models like Curiosity.
It's exciting that there are so many nations making efforts to work on space exploration these days.

Almost missed including this newer article about InSIGHT's work with orbiters on the magnetic field of Mars currently, related to the possibility of liquid water inside Mars.
Regardless as to whether water is active in bulk there, the story is yet one more mystery of the closest planet we can get to for mineral work and investigation of geology.

It would be better if we knew how deep this zoned, layered, surface material is where the lander is staged. It appears so well organized and structured, yet obviously was a very active deposit when formed.
