Martian Pebbles

The study is exciting not just for what it implies about Mars, but also opening up a new realm of possibility to quantify erosion.

While the world celebrates the signs of flowing water on Mars, researchers estimate that the Martian pebbles travelled roughly 50 km from their source, supporting the idea that Mars once had an extensive river system and conditions that could harbour life.
