Riverbeds found on Mars

Scientists estimate that these dried-out beds are more than 3 billion years old.

The discovery suggests that Mars was a much wetter and more humid planet than previously thought. Experts say this finding strengthens the possibility that Mars may have once had a climate system similar to Earth's.

Studies conducted in collaboration with NASA and the European Space Agency (ESA) have revealed valleys, sediment layers, and deltas on the Martian surface. These structures indicate long-term water flow, suggesting the existence of permanent river systems, not just short-term floods.

The discovery is also of great importance for the exploration of underground water resources for future manned Mars missions.
