Some evidence for the existence of & # 39; liquid water on Mars can & # 39; be wrong

Scientists from the Institute of Technology & # 39; California said the wrong data processing, obtained by the Mars Reconnaissance Orbiter, can & # 39; lead to the fact that the probe & # 39; erroneously identifies the presence of & # 39; hydrated salt on the red planet, writes Chronicle.info b & # 39; reference to the Telegraph.

This means that some regions & # 39; Mars, which in & # 39; this point assume the presence of & # 39; liquid water and conditions for the existence of life, can actually result in dry and lifeless.

The experts found problems while searching & # 39; hydrated perchlorates on maps & # 39; Mars, based on the information obtained by the spectrometer in the visible and near infrared radiation (CRISM). The perchlorates reduce the temperature of & # 39; freezing & # 39; water to 80 degrees, making it possible that there & # 39; liquid water on Mars. Traces of the presence of & # 39; perchlorates in the Martian soil detected by the spacecraft, Phoenix and Mars Curiosity Rover.

The presence of & # 39; minerals on the planet, researchers tested for reflection & # 39; different wavelengths from the surface through chemical b & # 39; in particular absorb and reflect light. However, the camera does not always CRISM b & # 39; correct way, with the result that detects spots & # 39; reflected light where m & # 39; should be. The algorithms for correcting & # 39; these errors, sometimes carrying the spectra at the same length & # 39; waves such as perchlorate.

By making adjustments to the algorithm for CRISM, researchers had the opportunity to consider even the smallest traces of & # 39; perchlorate on the surface of & # 39; Mars. The result was that perchlorates cover nearly all the Red planet. more thorough inspection revealed that the salts are present even where there is no geological reason for their appearance.

According to scientists, suggesting that some data on the presence of & # 39; perchlorates on the surface of & # 39; Mars turned out to be incorrect. The researchers emphasize that this does not mean that the salt on all the red planet, but it means they are harder to find
