I think the next Mars rover should be able to turn rocks over. That may sound whimsical but it would reveal a surface that possibly hasn't been exposed to sunlight in 2 billion years. It can be done.

Butterfly effect! Tiny vibration of tool on rock causes... tiny sink hole a meter away🤗

@DUKE_of_RAMBLE

Ай бұрын

I dunno if I'd classify it as butterfly effect in this instance. The rock they're abrading likely extends under the entire area that was visually effected, with the sinkhole probably being what had been an air pocket _under_ that rock. So the vibrations were a very direct cause, whereas butterfly effect would be indirect. _(at least in my opinion)_

Such a porous layer of sand in a low pressure atmosphere makes it a good thermal insulator. Any modeling of sunlight warming induced land slides could use this surprise discovery to estimate the sand’s thermal conductivity when calculating how deep would salty water melt during a Martian day

I think it's reassuring the sand flowed downhill and didn't collapse into crusted-over hidden voids. The target kind of looks like it is alone in a 'puddle' of sand. Now we know there is material underneath giving it support.

Like avalanches in snow? Actually, the most dangerous avalanche locations on Earth are all located where the slopes are within a specific range: if I remember right, 35 to 45 degrees. It's just enough to start the flow moving at increasing rates and pick up more along the way, thundering down upon anything below. The sands of Mars have had considerably more than one winter season to accumulate, and less gravity to shake them loose. I wonder what slope angle would be maximal for Mars. I suspect that it would also have much to do with the properties of the sand itself, but it's intriguing to think that the slopes might not need to be as steep there if the sand is more slippery than ice crystals. It certainly didn't take all that much to get it moving on that relatively gentle slope.

@@farmergiles1065 it’s an interesting thing to ponder: angle of slump, different gravities, particle size, particle shape. Water must play a part; the lack of; no sticky water! The low gravity and thin atmosphere must select extremely fine particles settling in liquid like in places. They must have considered the rover’s might land in a "quick" sand; same too for the lunar missions..

"Percy" haha never heard that before

Could be a case of Martian low density collapsible soil, where a similar situation on Earth, in dry climates with a prevailing wind, causes blowing sand grains to become weakly glued together by a lattice-like cement of slightly cohesive, moisture sensitive blowing silt grains. If the silt exceeds its optimum moisture content the cement dissolves freeing the sand grains to collapse and form denser layers. I've seen this in eastern and western Colorado.

Yeah, all the rovers have encountered weakly cemented "soil" crusts, so it seems to be a global process.

Could a very thin sheet of water or another similar liquid or solution moving at a constant flow, as in the caves of stalactites and stalagmites, for a long time, create these "trilobitic" shapes while being composed only of lime deposits, without organic matter from archaic living beings?
