Dunes on Mars spoke about his last day.
The Curiosity Rover found on the red planet a unique type of sand dunes that never met on Earth.
As reported on the website NASA, the ripples on the surface of dunes is associated with the depletion of the Martian atmosphere and may shed light on the peculiarities of its history.
Pictures of dunes of Sangolda was received by the Rover about six months ago, when he approached the North-Western slope of mount sharp. Then the researchers noticed unusual ripples. If on the sand dunes found on Earth, the lines in the sand is encountered at a distance of about 30 centimeters from each other, on a Martian dune strip are located at a distance of about three meters.
According to scientists, the bands that appear on Martian dunes, unlike the traces of the collision of wind and sand, it more resembles the effects of water movement on Earth. In addition, one of the sides of the bands was more flat than the other that also reminds us underwater education on our planet.
According to researchers, in the past the atmosphere of Mars was much denser, which allowed the wind to form a more sparse ripples.
