A team of Carnegie investigated hydrogen liquefy in water from the Martian subsurface, and found that Mars was formed from the same structure blocks as the Earth, and the changes in the chemical composition of the planet began to occur in the course of its subsequent evolution. This indicates that the terrestrial planets, including Earth, the same source of water - chondritic meteorites. However, unlike our planet, Mars rocks, which contain volatile components such as water, can be processed deep in the bowels of the planet.
The researchers examined two types of meteorites - one of them reflects the chemical composition of the material from the surface of Mars, is in contact with the atmosphere, while the other was a matter, having come out of a deep mantle of the planet and little has changed with the structure. The analysis showed that the sample from the surface contains about ten times more water than the sample from the depths of Mars, which indicates the presence of the past a lot of water on the surface of the red planet, scientists say.
The study was published in the journal Earth and Planetary Science Letters.
