This Week on Mars: Water, water!
Discovery of smooth pebbles add to Mars river hypothesis
Here's the weekly update from NASA's Jet Propulsion Laboratory on what the Mars Curiosity Rover is doing on the Red Planet.
This week, we get a discussion of the discovery of what appears to be an ancient riverbed, where water once flowed on the planet. The existence of smooth pebbles help explain why they were shaped by a strong water flow, instead of carried by wind. Very cool explainer from this week's JPL presenter, Sanjeev Gupta:
The Mars rover is continuing its journey to a new location on the planet, so we'll consider this week's discovery as the rover's "water break." While the discovery of an ancient riverbed is very cool news for the scientific community, I'm secretly hoping that rover will stumble on some old Martian bones.
