Summary

Story summary

Researchers identified 16 ancient drainage basins on Mars, each covering more than 100,000 square kilometers.
The rivers formed without plate tectonics and transported about 42% of all river-eroded sediment on the planet.
The study detailing these results was published in the Proceedings of the National Academy of Sciences.
The basins imply habitable environments and dynamic Martian water history, making them prime targets for astrobiology missions.
