The illusion of water: scientists have discovered that Martian satellites are "wrong"

Mars Reconnaissance The 90% of the planet in the middle of Orbiter actually showed what happened there.

Researchers have found that 90% of some of the photographs taken by Mars satellite Mars Reconnaissance Orbiter show what actually happened there. The error was calculated after finding the best findings of moisture-absorbing materials on the surface of Mars. They were not just a Mirage: now scientists have serious doubts about the precise distribution of water on the planet.

The compact discovery imaging spectrometer used for Mars mounted on a satellite is the an eye in the sky if that identifies the minerals on the surface of the planet and the accumulation of water. The procedure is performed by measuring infrared waves and visible light corresponding to different chemical structures, and then the data is distributed to pixels representing an area of ​​100 to 200 meters in diameter.

Pixels exhibiting minerals such as alunite, chimeric, serpentine and perchlorate will most likely appear when switching between the sensors between intense light and shade areas, and a fabrication filter responding to the various peaks in the data will inevitably occur. A number of researchers intended to explore the possible distribution of perchlorate salts, requiring a fine tuning of the filtration process using the new algorithm. In the end, they found that about 0.05% of the pixels flattened the clots so that they would look like perchlorate.

Fortunately, in the case of a large part of the problem of minerals, it lasts a bit. After examining the same areas using other tools, scientists found that minerals were mostly in place. But for the perchlorate – only a small part is real. This could be a serious problem.

The Mars atmosphere is thinned with water on a very cold and liquid surface. However, as a mixture with the perchlorate salts of the melting point, the retention of a small amount of liquid may be sufficiently low. Anyway, in theory.

After discovering the problem, CRISM will determine exactly where the perchlorate is on the surface of Mars. There are only a few pixels for damage, the current maps are blurry, but they don't work. You can also set the data received from the CRISM device using other tools.
