Irrigation canals on Mars had been hypothesized since the 19th centuries.
Of course, that implied intelligent life that might have once existed
How to explain those channels? Later advances in telescope technology
proved these channels to be optical allusion

Yet the question of water having once flowed on Mars still remained feasible.
Now with the latest geologically astute image
things are becoming a little more in focus

From NASA

In this image from NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust. The fractured Link outcrop has blocks of exposed, clean surfaces. Rounded gravel fragments, or clasts, up to a couple inches (few centimeters) in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of clasts of this size.

I read that the polar ice caps on Mars were frozen carbon dioxide and frozen water so if mars were ever warmer, stands to reason there would be water free flowing on the planet at one time....Mel

Ya know its interesting, Mel

I was reading that the temperatures recorded from the Curiosity
were warmer in the sunlight than they had thought.
Not 1000% sure -- but I think they were above freezing daylight
and drastic drop at nightfall.

How much sunlight hits the poles
or what those temps might be is an interesting question.

Nonetheless, they think found evidence of a running liquid
from the picture.
What that liquid might be is inconclusive
probably
and why doesn't it show back up?

Thanks!

Ed

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
