First photo of river pebbles on Mars

NASA specialists have compiled a panoramic image from several images taken by the Opportunity Rover on June 3, 2017 in the valley of Endurance on the edge of the crater endeavor. For better clarity and color depth, three light filters were applied to the images — infrared, green, and purple.

In an attempt to find an answer to the question of the origin of the stones in the zone that stretches from West to East through the rim of the 22-kilometer crater, scientists divided into two camps. Most red planet researchers believe that Opportunity is currently located at the bottom of a river system that existed on Mars more than a billion years ago. Others claim that the stones lying on the surface were always stationary, and if they ever changed their position, it was only from the wind, and not with the flow of water.

Perhaps further research on the Rover will shed light on the origin of the stones. You can view a panorama of river pebbles in the Martian valley of Perseverance on the NASA website.
