Some evidence of the presence of liquid water in Mars

Scientists from the California Institute of Technology, Mars reconnaissance Orbiter by the incorrect processing of the data, the probe can determine the presence of hydrated salts on the red planet can inadvertently determine the fact that, Telgrafa reference.

This means that some areas of Mars, assuming the presence of liquid water and the existence of life at this point, are actually dry and lackluster.

Experts have found a problem when looking for hydrated perchlorates in Mars maps, based on information obtained by spectrometers in visible and near infrared radiation (CRISM). Perchlorates reduces the freezing temperature of the water to 80 degrees, which makes it possible to have liquid water in Mars. Traces of perchlorates in Mars have been discovered by spacecraft Phoenix and Mars Curiosity Rover.

The presence of minerals on the planet, the researchers were tested for reflection of different wavelengths from the surface because the chemical in a certain way absorbed and reflected light in a certain way. However, the CRISM camera is not always accurate, it detects reflected light points where it should not be. To correct such errors, algorithms sometimes dips in the same wavelength spectra as perchlorate.

By making adjustments to the CRISM algorithm, researchers had the opportunity to see even the smallest perchlorate traces on the surface of Mars. The result was that perchlorates covered almost all the Red planet. A more thorough investigation revealed that even in the absence of any geological reason for their appearance there were salts.

According to scientists, this suggests that some data on the presence of perchlorates on the surface of Mars is inaccurate. Researchers say that it does not express the salts on the red planet, but it is more difficult to find.
