Mars, as we know it today, is a dusty, dried rock of a bit of ice here and there, but things have been very different for a long time. Through various missions conducted by NASA and the European Space Agency, we have long known that Mars once had a lot of water on its surface. Look at what once was a very humid area of the Red Planet. The photos show the landscape, which, in addition to the apparent impact of the craters remaining from ancient times, is very similar to the natural drainage schemes that we see here on Earth.
ESA describes what we see in the images:
The topography of this region indicates that water drops down from the north (straight to the main color, topography and 3D image) south (left), carving. valleys up to two kilometers in depth and 200 meters in depth, as was done. We see these valleys as they are today, having undergone a significant and severe erosion since their formation. This erosion is seen in the form of broken, smoothed, fragmented and dismembered valleys, especially in the east-west valleys. know where the water first appeared. ESA offers a number of options, including melting glaciers or even precipitation, but we can never know for sure.
The more we learn about ancient Mars, the more it sounds like the modern Earth. With running water and an atmosphere that could protect the roots of life, it is possible that Mars once lived. We still have no evidence that life existed on the planet, but it can not be long before we get it.
