    The ridges of “blue” sand in the image of the Mars Reconnaissance Orbiter make the surface of Mars even more unusual.

    The Mars Reconnaissance Orbiter has sent new images of the surface of Mars back to Earth. These are pictures of sand dunes that form in the Gamboa Crater in the Red Planet's northern hemisphere. They were specially treated and given a blue color to emphasize their difference from the surrounding area, according to ScienceAlert.

    The improved images of sand ridges look very nice, but NASA scientists did not give them this color to decorate the Martian landscape. Thus, scientists decided to emphasize the contrast in the features of the Martian surface, and such image processing allows us to better understand the geological and atmospheric processes on Mars. New images of sand dunes were taken in very high resolution by a special instrument of the Mars Reconnaissance Orbiter.

    The smallest sand ridges are separated by only a few meters, but they are grouped into large waves of sand, located about 10 meters apart. The blue tint of these sand formations makes it easier for scientists to see the distinctive features in the different sizes of mounds.

    The medium-sized structures, called transverse aeolian ridges, are composed of coarse-grained sand. Scientists believe that under the influence of wind, these and larger formations are subject to erosion.

    In some areas of this surface of Mars, sandy mounds move due to the wind, and darker dust is blown off ridge surfaces. Therefore, some areas appear brighter due to the color changes they received after image processing.

    Due to the distinctive features of the sand dunes, scientists can figure out exactly which direction the wind was blowing when they first formed. Also, the close location of sand ridges makes it possible to understand how sand interacts in structures with different sizes and thus it is possible to understand what exactly they are made of, scientists say.

    Focus already wrote that NASA will send two more aircraft to Mars to help collect rock samples for their further delivery to Earth.

    Focus already wrote that Elon Musk did not will be the first to send the first commercial flight to Mars. Two not-so-famous American companies want to make such a flight to the Red Planet as early as 2024.
