The Sol 415 images have arrived with only an apparent upward slight movement of the hammer.
I have decided to show the Sol 414 sun lighted view of the large object in front of the Insight deck.
This is a anigif and a still altered view.

Between 2:37 and 2:41 PM Mars time, on Sol 417, January 29, 2020, the Insight scoop arm was moved upward from pinning the hammer tube, and the current position of the tube is far higher than the past few weeks. The actions have caused a reversal of the penetration and the apparent decision is to give up on further assisted hammering at this time.

The future consideration during the warming season will be an additional approach. During the past couple weeks the pressure was increased and caused a deepening scoop depression and a bright streak along the tube where the scoop abraded the side wall.

The materials around the lander are of great importance now. What toughness or density or other characteristics are causing the reversals?
Are the objects around the lander deck rocks or artifacts appearing manufactured yet dropped onto the evacuated areas prior to the landing jets fired and burned the surfaces of the objects?
So many open questions...

Sol 420, with a major swing in temperature and pressure status, a precursor to possible major local weather activity? Wind direction averages from widely varied direction each day. A high of 10 degrees F on Sol 419.

Sol 417. The uplifted arm and scoop resulted in a view showing both a tight packing of the rounded gravel sized pieces on the back wall of the hammered hole, and a right side apparent folded layer shape on the spot below where the scoop bottom would be in contact with the 'flexible' fold. Would the appearance be a real fold in a consolidating material? Is there sufficient material leaking from the arm above to alter the spot where the linear lighted fold seems to exist?
If the soil back wall is the 'duricrust' pattern, is it more a tight packed gravel altered by local conditions over a long time period? Is it not solid but rather tough rounded objects capable of falling into a hammered hole below the tip? If the objects are packed tighter in the hammered and wallowed hole, perhaps the loose material around the tube is residue from sorting?

More hammering underway apparently with no arm assistance being used. I'll make an image of the new debris in the hole, currently waiting to see if they are making an anigif of the activity.

This is a back walking image comparison of the current weeks view of the underside of the scoop which was retracted and carried upward with the camera and arm the past couple weeks.
In prior imaging the underside of the scoop shows bright reflective patterns when not under direct lighting from the Sun.
The change occurs within an hour of timing during days, but the imaging was not done at close intervals often, so this enlarged view is of two days and several hours difference in sun angle.

Enlarged to 3X at DPI 72, Sol 422 and Sol 423. Times just after noon local Mars time and just before 4 PM. Alterations are on the host image name if you mouse over the image when viewing.

If the frost appearance is substantial in the dust on the scoop, is it an indication of a real difference in the soil as well when the lighting is not effective below the surface?
Is the appearance somehow not as substantial as it appears? What causes such a strong change in the metal surface of the scoop? Is the Iron type in the soil responsible for the change in the patterns?
