The big success story of the Mars rover and orbiter missions has been the confirmation of Mars as a former water world, with current massive deposits of water ice almost everywhere that would be accessible with a plain old backhoe if we could land one. For example there's a subsurface glacier in Utopia Planitia starting at just a few metres under the dirt that has more water, in the form of ice, than Lake Superior here on Earth.
Pretty sure it's the US, the terrain looks like water flowed through it at some point.
It does so on Mars as well
The entire crater where curiosity roams used to be a freshwater lake
