Question: What do you about mars?

I know quite a bit about Mars. It is really interesting IMHO because it used to be wet and warm and have an ocean when it was first formed, so like Earth. But now it is a cold dry desert planet. And I am studying why it changed and where all the water from the ocean went. We know there are huge glaciers under the sand in some places, so some of the water went there. But Mars is still like on Earth in some ways, because it has ice caps at its poles, and there are some clouds in the sky and it even snows at the North Pole. I think it would be amazing to stand at the North Pole on Mars and be in a snow storm.
