Ancient Mars: Long-lasting rivers once carved its surface

Geologists from MIT have developed a new technique using satellite imagery to study ancient rivers on Mars and Saturn's moon Titan. The team found that rivers on Mars may have flowed for at least 100,000 years at Gale Crater and 1 million years at Jezero Crater, potentially creating habitable environments. The same technique was applied to Titan, revealing that methane rivers on the moon should be wider and have a gentler slope compared to Earth or Mars. The research provides insights into the past habitability of Mars and the unique characteristics of Titan's rivers.
