The waves spread out in a triangle, with maximum amplitude along the edges of the V-shaped region and a variety of ripples within it. Remarkably, the angle at the apex of the V is fixed at about ...

Shallow puddles enable ripples because they are much thinner than they are wide. The balance between the surface force — between the water puddle and the air above it — and the gravitational ...

"This is the best evidence of water and waves that we’ve seen in the entire mission," Ashwin Vasavada, Curiosity’s project scientist at NASA’s Jet Propulsion Laboratory, said in a statement.
