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?

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.

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

The weather report is incoming once again.

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.

An RGB 'nomap' view of InSIGHT, but not quite discerning any of the active equipment yet, the arm and MOLE housing showing a little shadow, and a bright spot/area near the hole but possibly too far from the lander to be the actual hole with the metal hammer end. Probably a small rock causing some of the brightness where the slightly dark shadow is cast to the left of the SEIS glare.
Some bright lander deck detail, but no resolution available. A hint of the struts on a solar panel. Color/contrast altered by an 'auto' adjustment.

This mission was a carefully planned and studied operation. The considerations about materials and surface was under study for a period of time, several years actually.
This is a view of the placement of the fixed location lander.
There are several structures at the landing spot, and the solid nature of the subsurface was described as 'tens to hundreds of meters of shattered debris' in various publications which were paraphrasing the teams studying the landscape. This is not any criticism of the process and placement.

And the original HiRISE image browse small view online, gives an understanding as to just how carefully the landing was accomplished.
Several flows, ridges, thermal structures, and wave trains were intercepted and are just below the lander deck.
This is a fine spot for a deep drilling sample mission.
Unfortunately the ground is not broken to the depth suggested. If this were a mission with chemical analysis it would be smash hit with science and the public.

An RGB over near IR black and white view, with all my images rotated to the right at 57 points, giving the structure of the crater ring a horizontal orientation. The ridges and flows are trending at a slight diagonal but nearly horizontal.
With some care you can see the altered shapes in the original HiRISE views.

Is it time to study multiple landers for each location?
Is a reworked drilling device worth the investment for this and other choice locations?

The far left lower corner of the image for Sol 295 shows a spots with a bright ring around each in the recesses, and I believe it appears some of the 'debris' on the recess area may be cast or covered layers of some of the original equipment, but the general appearance is of frost or reflection in the angles of the shaded recesses.

The view of the MOLE hole is not changed much but is a little blurred partially due to the distance in the full frame view.

Views of the marked original and other unpublished aspects of the various replies are available at the image host if you have the Forward and Backward buttons I have in my view.

Sol 298 images issued today and we have activity at the arm scoop and the hole, with an approach to near contact over an hours timing, yet no apparent contact.
The sunlit larger rock shows a deep alteration and change from either the landing or prior with a layer of altered material attached to the lander body side of the rock.

Just started looking at these items.

Closeups later.

Sol 300, and the image total is now 3,000.
This is a 3X view of the small tubule rock object near the arm in the background, at DPI 72. The second image is the tip of the scoop which is near the ground, and has both dust and residual dust or frost type apparent material running toward the back area of the scoop shadow in correlation from the dust on the scoop. I have seen this before on the scoop but it seems to be forming just apart from the dust clumps, much like the metal recess area of the deck showing bright rings around the small clumps on a previous day.

Sol 299 for the scoop enlargement.

Sol 301, October 1, 2019.

The view of the drifting material which may be dust or frost, is barely apparent in a 3X image slightly altered from Sol 298. The image was one of several taken on Sol 298.
The drifting material carried by the wind apparently, and deposited on the scoop, was not like the early Sol 008 ice deposits which were available inside the scoop just a week after the landing.

Sol 298 at 3X, DPI 72.

Sol 008, first a 3X at DPI 72, then a crop view of the landing related timed ice crystals on the upper scoop.

The very different appearance of the ice and the drift material makes a question about the cause and content.

Sol 301, and the ICC camera shows in the shadow zone sections of what appears to be subsurface exposed patterned ground masses, possibly areas of the duricrust type material described at the site. There also is a area on the upper MOLE housing which appears spotted and bright, limited in area, yet only approximately as bright as the local sunlit areas. I altered the three areas and made a 3X enlarged view, including a cutout crop of two with the patterned ground sections.

The arm and scoop have been moved to direct contact with the hammer device at the upper end of the metal tube. There is no contact with the ground surface in the most recent image release.
It appears no hammering has occurred as yet.
I have a 3X enlarged view which can be seen full size at 960x720 and DPI 72. The thumbnail is about 1/3 of the available view. The original image crop was 320x240 prior to enlargement.
In the view, right at the twist and flexing of the cable is a probable adhesive set of two droplet shapes centered between the conductive printed metal instrument communications lines. Due to the particular placement and the previous views of these 'droplets' I assume these cannot be ice or liquid, and the droplets are too large to be clear drops of water or other liquid now frozen in the current shapes. It is an intrigue how they are just at a near horizontal valley in the cable twisted shape.
The scoop has stable drifts of the bright fine material carried apparently by the wind from the new dust on the scoop lip area.
17 new images available on Sol 303 thus far.

Original view.

A earlier view of the scoop area with entirely differing lighting as this is an unusual early morning view, about 11:36 AM with sun from the left.
The dust on the scoop should be apparent, yet even in altered views it is nearly not visible. The droplet shape on the instrument cable looks entirely different as well. The appearance is of a 'pass-thru' shape with almost no hint of a textural droplet shading and reflection seen in the afternoon images. This is a 3X early view of the hole with scoop. Even the 'dust' on the metal tube of the hammer mechanism is nearly not seen.

The landing site is becoming even colder during the transition into springtime near the latitudinal equator. Predominate winds are from the South and East recently.
