Do Martian clay deposits prove...

I don’t know. It kind of looks like that satellite photo the neighbor showed me of our block back when everyone had young kids and there was a trampoline in every back yard.

My son discovered obvious evidence of glaciers that existed in the Northern regions of Mars. They may have disappeared only a few million years ago. He said that it was evidence that Mars has warmer, wetter periods when there is liquid water on the surface.

BTW, he did this at least a year before papers were published using the same data.

He was taking an undergrad course in remote sensing for geology. He found all the evidence using satellite photos.

Now, only a few years later, he’s making more money than his old man. In oil exploration, of course.

My offer is still open. I bet all takers $100 each that we find life, at least microbes, on Mars.

Any takers?

Obviously, the Martian water was already stolen by Los Angeles.

It has been theorized that both Earth and Venus were subjected to numerous impacts by large bodies, which increased their size and mass considerably, but Mars avoided the big collisions.

Perhaps the largest, or the last, collision to hit Earth is estimated to be about the size of Mars. Venus is about 95% the size of Earth, Mars only about 50%
