Hello, I was reading that NASA was testing a craft that could land on Mars and the article mentioned that since there's no water on Mars the craft can't land gently in it. As I was reading I wondered, can't we invent a device that could carry a certain amount of water to be deployed before we land? We can look at Mars and measure the radius of a crater and the profundity as well. Of course if it takes millions of dollars on fuel just to depart from Earth, carry water to Mars could be consider pointless and unecessary. But if we manage to make a little landing zone where crafts can land gently it would be better right? What do you think of my idea?
Also I was wondering, what happens to water on Mars? If we take for example a galon of water and we leave it on Mars, in how many time it will evaporate?
Thank you for your time.
