Recent research reveals a vast network of ancient riverbeds across Mars's southern highlands, transforming our understanding of its history.
These river systems, spanning nearly 10,000 miles, are believed to be over 3 billion years old, indicating a sustained period of significant water presence.
The discovery in the Noachis Terra region challenges previously held beliefs about this area's arid past.
High-resolution orbital images reveal the extensive network, suggesting regional precipitation played a crucial role in shaping the Martian landscape.
