This paradox is why scientists History and Chemistry of Mars An interesting topic that deepens their understanding of the subject.

A little piece of Mars, about which we learn something new every day. on the rusty surface let’s see.

The atmosphere of Mars is very different from that of Earth.

About 95 percent of Mars is carbon dioxide. The free oxygen percentage is quite low, about 0.13 percent. So much low oxygen level It is not enough for metal surfaces to oxidize and rust, as on Earth. So, what is the source of the rust on the surface of Mars?

The source of rust on the surface of Mars is the formation of iron oxide (Fe2O3).

Large amounts of Martian soil and rocks iron Contains. However, oxidation of this iron does not require free oxygen. In fact, there are two major mechanisms for the formation of iron oxide on Mars:

Water, known to have once existed on the surface of Mars, contains oxygen atoms, which react with iron to form water. iron oxide can make. The history of water flowing on Mars is thought to go back millions of years, and during this time iron may have oxidized by reacting with water.

The other one is photochemical reactionsThe surface of Mars is directly exposed to the sun’s ultraviolet (UV) radiation. These UV rays can also break down carbon dioxide and water vapor molecules in the Martian atmosphere, creating free oxygen atoms.

Free oxygen reacts with iron on the surface to form iron oxide. This photochemical process also plays an important role in the formation of iron oxide on the surface of Mars.

The Past and Future of Mars

The rusty surface of Mars not only provides information about the chemical structure of the planet, but also provides clues about its history. The fact that Mars had water in the past is actually due to the fact that the planet once had water. can support life It also suggests that there may be circumstances.
