Another stunning image released by NASA on 8 April by planet Mars, makes the rounds of the world. This image shows an area covered by a sea of blue dunes surrounding the northern cap of the Red Planet, where temperatures can reach -150οC (-238F).
The image also shows wind lines around the lid of the north of Mars. NASA said the section shot in the shot represents an area of width 19 miles. According to NASA, the dunes cover one Texas size area, the second largest US state, which has an area of approx 695.662 km².
The photo is an incorrect color image, which means that the colors are representative of the temperature. The US Space Agency noted that blue represents the coldest climates, while the shades of yellow and orange represent the "dunes heated by the sun".
This image consists of a combination of photographs taken from December 2002 to November 2004, from its Thermal Emission Imaging System (THEMIS) Mars Odyssey. Mars Odyssey is a robotic spacecraft orbiting Mars that uses a thermal imaging system to orbit detecting water and ice on the planet.
According to NASA, THEMIS in Odyssey can see "infrared reflections from the surface of Mars". In addition, NASA noted that the image of the dunes "is part of a special set of images that mark the 20th anniversary of Odyssey, the spacecraft that has stayed on Mars longer than any other spacecraft. The robotic spacecraft was sent into orbit April 2001 and since then he captures snapshots from the planet Mars.
