Mars study traces erosion history on Red Planet in search for water


Now we can factor erosion on the Red Planet into our search for life on Mars.

A new study attempts to find periods of more intense erosion on Mars in hopes of understanding when water flowed on the world’s surface. Water can carry larger pieces of rock into collisions, breaking the rocks faster, so accelerated erosion might be a signal of watery, and in turn potentially habitable, conditions.
