Red planet is a rich source of perchlorate used for soil fertilization and produces chemical compounds of rocket fuel that are rare in the nature of the Earth.
The results of laboratory experiments indicate that these compounds can be formed on Mars due to electric fields generated as a result of global storms of dust or winds known as dust devils, according to Urt and Planetariums Letters.
Based on data collected by the spacecraft Phoenik and Curiositi Marsh, scientists have been suggesting more than 5 years of perchlorate is relatively common on Mars. On Earth, the chemical reactions that generate their production usually trigger the sun's light. Models of atmospheric chemical reactions, however, reveal that the sun's light is not enough to do the same on Mars. It turns out that strong magnetic fields, such as those generated by static electricity in global dust storms, can "destroy" gases in the atmosphere of Mars and thus trigger reactions that produce the production of perchlorate.
To test this thinking in a laboratory environment, scientists at the University of Washington have set up a blend of gas that is a miniature copy of the Martian atmosphere and consists of 95% carbon dioxide, 2% nitrogen and argon and 1% oxygen in a large chamber together with chlorine sources . Temperature and pressure in the camera were reduced until they became similar to those on Mars. The gas mixture was then subjected to electric fields, the force of which was similar to that of Mars dust and dusty devils. Almost immediately, some gases formed highly reactive, positively charged versions of carbon dioxide, carbon monoxide and nitrogen molecules. Later, the reactions generate a significant amount of ion chlorate, containing one chlorine atom and three oxygen atoms, and perchlorates. Tim believes that the level of perchlorate formation in Martian stormy storms may be 10 million times greater than the amount of sunlight.
Perchlorates are intriguing for astrobiologists. These substances are toxic to humans, but are used by some microbes to stimulate their metabolism.
