Detailed photos of the dunes on Mars were taken by the Mars Reconnaissance Orbiter (MRO) spacecraft, which is equipped with a special HiRISE camera. It allows you to take pictures in incredible resolution. According to ScienceAlert, new photos show the dunes on the Red Planet – this is one of the types of sand dunes.
The spacecraft sent to Earth a series of images of the planet’s surface and formations, they are formed by the Martian wind. Such dunes can also be found in the deserts on Earth, but here they do not look like this. On Mars, they are located in the North Canyon region, which has a length of 560 km.
The HiRISE camera is unique because it captures images with the highest detail. So, with its help, you can show an object on Mars the size of an office desk from a height of several hundred kilometers. Thus, scientists can study small objects that are about a meter in size on the surface. The new images show areas of dunes that are 1 km in size, and the photos were taken from a height of 197 km.
At the North Pole of Mars, the winds blow in different directions. Therefore, here the dunes do not have the usual crescent shape for the Earth. They are more like waves.
Color filters were used for the shooting, due to which the dunes are presented in an unnatural blue tint. And such images will allow much more to learn about the seasonal differences in the Martian atmospheric processes.
