Scientists have discovered nearly 10,000 miles of ancient riverbeds in Mars's southern highlands, indicating the planet was once much wetter than previously thought, with evidence suggesting regional rainfall or snowfall about 3.7 billion years ago. These findings challenge previous assumptions about Mars's arid history and imply a more extensive past presence of surface water.
New research indicates that Mars had over 15,000 km of ancient riverbeds, suggesting the planet was wetter and had more stable surface water during its early history than previously thought, especially in the Noachis Terra region.
New analysis of data from NASA's Curiosity rover suggests that many of the craters on Mars may have once been habitable rivers, indicating the potential for ancient life conditions. Researchers used numerical models to simulate erosion on Mars and found that common crater formations are likely remnants of ancient riverbeds. This study provides a new interpretation for Martian crater formations and suggests that there could be undiscovered river deposits elsewhere on the planet. The findings offer a more optimistic view of ancient life on Mars and indicate that the planet may have had far more rivers than previously believed.
