Why does Mars look purple, yellow and orange in ESA’s stunning new satellite image?
Despite being known as the red planet, March shows his swirling yolks, her oranges and her brown in a new satellite photo of the European Space Agency (ESA). The surface of earth tones also reveals a impact crater And four Devils Sneaky Dust Few crossing the region.
THE Rothko The image was taken by a high resolution camera on ESA Mars Express Orbit and Capture Arcadia Planitia, an essential March of March for research on the past of the planet and its potential to house humans in the future.
Arcadia Planitia
Northwest of the highest volcanoes in the solar system, Arcadia Planitia is a region of intrigue. It is loaded with solidified lava flows which, at most, 3 billion years. We also think that the area hosts water ice Near the surface of the planet, making it an area of interest when planning future missions towards Mars, according to a declaration of ESA.
Arcadia Planitia is home to visit “Devars Dust“Short-lasting columns similar to small tornadoes. The dust devils are formed when the Martian surface warms up the air just above, leading the air to get up and draw the dust with it. The new image shows four dusty devils as they wind their way through the plains of the region. Easy to ignore, you can spot them like whipped dust Classing the limit between the brown pieces of the darkness and the light.
A large impact crater is in the lower right corner of the photo and measures 9 miles (15 kilometers), according to ESA. The formation of layers in layers around the crater proves that the floor included notable quantities of water ice during the impact, and the lack of clear erosion of the crater the date relatively recently on the geological chronology.

Is the image disconnected?
If you have noticed that the image is blurred, you discern an effect of the wind on Mars. Air collection gusts and wear tiny debris particles on the surface of the planet, which creates a minor visual mist.
The wind that causes mist is also responsible for the reddish zone at the top of the photo. The red region is covered with ridges called “yardangs“” which form when the wind erodes the vulnerable rock and leaves the rock most resistant still standing.
Below the red section is the purplish brown terrain, which has a high concentration of silicates and a low concentration of iron, notes the declaration. The difference in colors also comes from the properties of sand, such as density and size, which affect the way the grains accumulate and travel through Mars.
