  • Scientists have mapped 16 major ancient river basins on Mars, including Paraná Valles.
  • The basins were identified using valley networks, lakes, rivers, canyons, and sediment deposits.
  • The Large drainage systems on Mars cover 100,000 square kilometres or more, similar to Earth’s large rivers.
  • These areas show evidence of ancient flowing water, erosion, and sediment transport.
  • Large basins represent 42% of the total material eroded by rivers on Mars, even though they cover only 5% of the planet’s terrain.
