Although Mars is known as Red Planet, he shows his swirling yellow, oranges and browns in a new satellite photo of the European Space Agency (ESA). The earthed surface also shows a impact crater and four sneaky dust devils that move across the region.
The Rothko-like picture was taken up by a high-resolution camera on the Mars Express Orbiter from ESA and captures Arcadia Planitia, an area of Mars that is of crucial importance for researching the past of the planet and its potential for man in the future.
Arcadia Planitia
Arcadia Planitia is an intrigue region northwest of the highest volcanoes in the solar system. It is loaded with solidified lava flows that are at most 3 billion years old. It is also assumed that the area of water is housed near the surface of the planet, which, according to an explanation of the ESA, is of interest if it is planning future missions on Mars.
In Arcadia Planitia there are “Dust Devils”, short -lived wind columns that resemble small tornadoes. Dust Devils form when the surface of the Mars is heated directly over it and causes the air to climb and pulls dust into dust. The new picture shows four dust devils when they close over the levels of the region. Easy to overlook, you can see it as a whitish dust buff near the center of the picture and span the border between the darker brown and lighter red parts of the level.

A large impact crater is located in the lower right corner of the photo and, according to ESA, measures 9 miles (15 kilometers). The formation of layer material around the crater is proof that the soil comprises remarkable amounts of water ice during the impact, and the lack of clear erosion of the crater dates relatively that on the geological timeline.
Is the picture blurred?
If you have found that the image is blurred, you will recognize an effect of the wind on the Mars. Air gusts take and carry tiny rubble particles from the planetary surface, which creates a small visual haze.

The wind that causes the haze is also responsible for the reddish area in the photo. The red region is covered with combs, which are referred to as “yardangs”, which are formed when the wind undermines endangered rocks and leaves the most resistant rock that is still standing.
Below the red section is the fur -brown area, which has a high concentration of silicates and a low iron concentration. The difference in the colors is also based on properties of the sand such as density and size that affect the accumulation of the grains and drive over Mars.
