If there were rivers on mars , what has happened to the water?

It's been a long time since I started ignoring these kind of "discoveries". I say to all space agencies, show me the water running thru before you call it river. For now, they only were able to show dust and rocks. That means :

- Lots of money wasted while more and more people become homeless and starve to dead right here in this planet.

- They already found what they were looking for, but showing us boring pics.

Meanwhile.....they keep the money flowing. Mars gold is on planet Earth taxpayers.

This is near where the Gale Crater that the rover is exploring.

Gale Crater is believed by NASA to have once been a lake or even an ancient sea. Curiosity has already found was is probably an ancient stream bed in Gale Crater.

That ancient river bed in your OP would be worth seeing, but there is enough in Gale Crater already that will probably take the lifetime of the rover to explore. Curiosity has not yet even got to its prime Gale Crater target yet -- that would be the exposed rock strata of the sides of Mt. Sharp (Mt. Sharp is now officially named "Aeolis Mons").

Aeolis Mons is in the middle of Gale Crater, and is thought to have been made by the lake/sea that may have once covered Gale Crater. NASA scientists believe Aeolis Mons is made up of the sediment that was laid down at the bottom of that sea or lake over millions an millions of years. After the water disappeared, wind erosion carved away much -- but not all -- of the sediment, once again exposing Gale Crater, but leaving behind some of that sediment as Aeolis Mons/Mt. Sharp.


EDIT TO ADD:
By the way, Curiosity and Gale Crater are more than 1500 miles away from this ancient river bed. That's way, way too far away.
