Pretty pictures. But if you are going to have liquid water that means you are going to have an atmosphere. Which means you are going to have weather- like Earth you have clouds. It also means you will have wind which means on Mars you will have even bigger dust storms. This will block the sunlight which then makes things colder. So the pictures are an impossible fantasy. I think the only way you could have liquid water on a planet such as Mars is if you had nearly global cloud cover and fairly dense atmosphere which gives a fairly uniform global temperate- and volcanic heat. Or most of planet covered by ice/snow with patches thermal heat making liquid water and allowing these clear skies
