Evidence for water on Mars!

Because planetologists call that other stuff "ice". I was thrilled by the thread's title, only to be disappointed. We already have compelling evidence for past water on Mars. cn

I think this is a bit more. The robot is in a river bed. We have never had conclusive evidence for flowing surface water before. Hint's only.
This is pretty clear, unless someone can come up with another explanation for all the rounding on this gravel.

What this says to me is there could be water flowing underground. Same as it every was. An actual river bed is a good place to dig.

Underground water is not a bad idea. However, I would think looking for a cave entrance to the underground water system would be better than making a robot that can drill for water and paying for shipping to mars (lulz). We already have a satellite's in orbit around mars so we would have what we need for now.

I would have been surprised to NOT find alluvial cobble in an erosional feature. Of course, maybe it's just me being a grumpy Gus. cn

They need to send another piece of equipment up there, a really high powered sonar land surveyor.

This Just In!

Or how about a piggyback with a climber that can go explore up to those out-gush spots? They are high in the wadi wall and possibly represent the layer of ground water...if any.

Ground penetrating radar is another good idea. And yes, cn, if we had landed there and not found cobble, that would be quite odd, as well.

So, was there water? Perhaps.

Is there water? We can only hope. Detecting H2O based "ices" is a far cry from finding water. Agree with that also.

It is worth noting that NASA did not find any large lake, ocean, river, or even a stream on the planet. Scientists have discovered hydrates in various parts of Mars, which contain water molecules. Perhaps this indicates the changing seasons in these regions. Temperature changes cause water to run down the slopes, creating dark streaks. They appear during the warmer months and disappear during the colder months.

Well, I think Perseverance should find out more about the water on Mars. At least, we know that water was on Mars. It was long ago, but it was. Each year scientists make discoveries. I wonder what else we will find out about Mars?

Did anyone apply to go to the moon last month for the 2023 free trip with that Japanese Billionaire? I was gonna to but got side tracked.

I'm hoping they will release one here in CA. Where's my water!
