Traces of hydrothermal springs found on Mars

The Martian orbiter Mars Reconnaissance Orbiter (MRO) found on the surface of the Red Planet two characteristic regions with large-scale sulfide deposits, characteristic circular and elliptical formations, and also a much brighter color than the rest of the planet's surface. NASA experts believe that the new find is nothing more than traces of hydrothermal springs that "worked" at the moment when liquid was present on Mars.

Experts say that on our planet hydrothermal springs are the first habitat of the very first representatives of life. On Earth, such sources exist in the oceans, and their contribution to the heat flux of the Earth is about 20%, about 35 billion tons of highly mineralized hot (350 ° C) water flows out of them through the so-called black smokers annually.

As for Mars, here the sources are located between the cratered plateaus of the western part of the Earth of Arabia and the Vernal Crater. According to scientists, several billion years ago there could be water in this region.

NASA notes that primitive life could well have arisen near Martian hydrothermal springs, since 2-3 billion years ago on Earth there were almost the same initial conditions. Sources could provide potential life with heat, energy, and organic compounds.

Unfortunately, now this is just a theory, because today Mars has become perfectly dry and very cold. “It’s necessary to study the surface of Mars from its orbit to find new traces of sources or to verify their absence,” says Carlton Allen, a specialist at NASA's Johnston Space Center.
