"We detected a lot of water in the central area of Vales Marinelli – a reserve far more than we expected."

In the most amazing area of the Red Planet, water ice may be buried just a few feet from the surface.
The latest research is based on data obtained by the Tracer Gas Detector (TGO). The probe is part of a non-manned Mars exploration mission carried out by the European Space Agency and the Russian Space Agency. The entire mission system includes the Tracer Gas Detector, launched in 2016, and Rosalind, which is scheduled to launch next year. Franklin Detector. Among the devices configured on the tracer gas detector is a device called the High-Resolution Superheated Neutron Detector (FREND), which can detect one of the elements that synthesize water molecules, hydrogen. The latest FRED data analysis shows that in the canyon-strewn Valles. The central area of Marinellis is Kanda. There is a lot of hydrogen in the Chaos Canyon.
Senior scientist alexei of the Institute of Space Research of the Russian Academy of Sciences. Malakhov is also a co-author of this new article. He said in the ESA report: "We detected Valles. The central area of Marinellis has a large amount of water that far exceeds our previous expectations. This is much like the permafrost region on Earth, where water ice is permanently sealed under the permafrost due to chronic low temperatures. ”
It is located in Valles near the Martian equator. Marinellis is the largest canyon in the solar system and the most prominent feature of the surface of Mars, with a diameter length ten times the length of Earth's Grand Canyon and five times its depth. Previously, scientists had searched for Water Ice at the equator of Mars, but at the time they were only able to study the surface atmosphere and found only a small fraction of the water.
The new study expands the depth of the scientists' research, allowing them to observe both the upper subsurface surface and the surface at the same time.
Lgor Mitrofanov is another scientist at the Institute of Space Research of the Russian Academy of Sciences and the first author of the new study. As the lead researcher of the FRED instrument, he said in the report: "With the tracing gas detector, we were able to probe the area 1 meter (3 feet) below the dust to understand the real world below the surface of Mars." Unfortunately, however, previous devices were unable to detect and locate water storage points. ”

The exaggerated and miscolored valleys of the vertical view become large Martian canyons covered with water. Whether the ditches on Mars were ever filled with surface water or groundwater has raised a high degree of controversy. The ditch is 25 miles (40 km) wide, 1.6 miles (2.5 km) deep and more than 310 miles (500 km) long.
The researchers say that if the hydrogen they detect comes from water ice, the precious compound will be able to create about 40 percent of the near-surface material in the region. However, FREND was also able to detect water in surrounding minerals, although scientists believe this is very unlikely in comparison.
Harvey. In the report, Sweedem said: "This discovery is an exciting first step, but we still need more observational data to identify the constituent elements of water that are currently discovered." "Harvey. Svedem is a former scientist in the research section of the ESA project tracing gas detectors and a co-author of the new study. "Whatever the outcome, this discovery demonstrates the unparalleled capabilities of the Tracer Gas Probe equipment, which gives us insight into what is happening below the surface of Mars and reveals to us the existence of shallower, more probingly large reservoirs in this area of Mars."
According to the ESA report, the new study is largely based on data obtained by FRED in May 2018 and February 2021.

Scientist Colin of the European Space Agency's Tracer Gas Detector Program. Wilson said in the report: "Learning more about how water on Mars is currently produced and where it is located is necessary for us to figure out what happened to once water-rich Mars, which will help study the habitable environment, the signs of early paleontology on Mars, and organic matter." ”

Mars, the fourth closest planet to the Sun, is the second smallest planet in the Solar System after Mercury, and is one of the four Terrestrial planets in the Solar System. The West calls Mars Mars, the god of war in Roman mythology, so in English, Mars is the meaning of the Roman god of war, usually called "Red Planet"; in ancient Chinese, it is called Ying confusion because it is like a fire, and the position and brightness often change unpredictably.
