Scientists believe Mars was once a wetter planet because of geological features such as dried-up river valleys, lakebeds, and mineral deposits that suggest the presence of liquid water in the past. Additionally, data from Mars rovers and orbiters have detected evidence of ancient water flows and weathering processes that could have only occurred in a wetter environment.

Additionally, data from Mars rovers and orbiters have provided evidence of the presence of these rock types on the planet.
