Although Mars looks to be an arid and barren world now, its surface holds significant evidence suggesting the past presence of flowing water.
This evidence includes the presence of dried-up river channels, remnants of ancient ocean and lake beds, and valleys marked by water erosion.

According to the ESA release, this is the “most water ever found in this part of Mars, and enough to fill Earth’s Red Sea.”
