Simulating ancient water flow on Mars

An experiment on Earth simulates the sudden release of water into a crater on Mars, reproducing the pattern of sediment deposit seen in a real crater on the Red Planet (Video courtesy of Erin Kraal et al/Utrecht University/Nature)

nobody asked you to watch this.

Not beneath, but as a damn, earthen or icy/earthen breaking.

This is a simulation and not a real photograph, btw.

From atom analasis (something like that) and distinguishing the patterns returned by telescopes and radiowaves, etc, they were able to conclude that hydrogen and oxygen (bound together as H2O) were present on the planet.

Perhaps a telescope has seen polar icecaps on Mars but I'm not too sure about that. I remember hearing before in my Astronomy lecture that some planet (perhaps Mars) has carbon dioxide or methane "ice" caps?

@ashthegreat What are you talking about? lol. i just simply said we have picture proof that there is ice on the north polar part of mars, and that we are trying to get there to see if there is life. And that i believe that there is life somewhere in our galaxy or beyond?

Hehe, just one note: Copy my entire coment including "@ZigZag1808" to obtain the complete character count.

@ZigZag1808

If you count the characters in my last post (simply copy-paste it into a new comment box and note the character remaining limit), you will somehow notice it is composed of exactly 500 characters - the limit for a typical Youtube video comment. And I did not intend that, at least not conciously, I think.

Back to the 1st point: If old "proof" itself has been proven to be wrong then what is proof other than a generalized belief by many people? Some exceptions lie in this "proof".

@ZigZag1808

It's good to see someone enthusiastic such as yourself. But please try to considerately keep in mind that science can never prove something as you can never perfectly prove something to be true as truth is too hidden to be grasped and perfection cannot be ever be made without being changed in our completely dynamic world. Since ideas are generally stationary, it is too unlikely to be a good candidate as perfect models. Are what you think about right now perfect? What is perfection?

[ZigZag1808]

@ashthegreat No its proven that there is a ice polar on the north pole of the planet. What we are trying to do now, it get there, and see if there is complex living life that adapted to living under the ice. Crazy huh? i believe life is alot closer then we think..

@ashthegreat I mean the Martian water in the past, the one that caused the flood.

[ashthegreat]

Scientists believe there is ice on the polar caps of Mars.

Interesting, but astronomers still unsure wheres the source of this water.

The ancient water of Mars was very different with Earht' water. It's likely that there was no large ocean on Mars, but it seems that somewhere in the past, an enormous mega hyper supercalifragilistic flood happened in Mars (just like in this video). nobody really sure where is the source of this sudden flood.

I think it may have something to do with the lavas, the flooding r found mostly around Mars' volcanic area
