Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Wow! incredible sketchfab djellison, thanks!
It seems we've managed to collapse the sub-duricrust layer into a jumble of sand with what looks like the cohesiveness of styrofoam pellets, seemingly held together by a very weakly cemented loose matrix of muddy salt residues left over from eons of dessication, never disturbed until now. I'd imagine walking very cautiously here with my boot plunging into the subsurface regularly like dry quicksands. To further the Earthly comparison, very similar to what happens regularly at the beach when a layer fine sands is washed to cover over a deep layer of very large sand grains that were deposited without any small grains to fill the gaps, and so when the tide goes out and it all dries up it doesnt collapse under its own weight but remains loosely cemented in place, so you walk along as your foot plunges through a crispy crust to squish away large volumes of the larger mobile sand grains below, sinking deeply and softly with every step. So now doing some very unplanned-for trenching studies in order to reveal the true cross section of the soil layers and how they react might prove critical to making safe progress with whatever plans are in the pipe..? |
