Is there an atmosphere in Mars's heart?

According to a study published in the United States, carbon dioxide and carbon dioxide (CO ₂ ) previously created Mars's dense atmosphere dispersed with low concentrations in space and can be present in the underground of onions. red crystal.

Based on data collected by the Mars Mars Express probe of Europe, a group of European researchers determined that the Martian atmosphere disappeared about 3.5 billion years ago to escape a little in space due to the effect of solar wind.

Two study authors Stas Barbash (Swedish Institute of Space Physics) and Jean-André Sauvaud (Center for Toulouse Radiation Research, France) confirmed only 0.2 to 4 millibars (unit of pressure measurement ) of CO2 and a few centimeters of water escaped into space.

Researchers have investigated where Mars's dense atmosphere goes and they think it can be present in Mars underground.

Two Opportunity and Spirit self-propelled robots have once confirmed that the Martian atmosphere contains water and CO2. Many evidences such as sediments, traces of the coast and shallow river have been confirmed on Mars.

The concentration of water vapor in the atmosphere is very low, water exists in the form of ice in ice caps and some craters. But this amount of water is not enough to explain the traces of observed geology, so researchers claim large areas of water can be present underground Mars.
