Now there is more evidence that Mars may have been another earth



There is a reason for persistence, dating back at least 3.5 billion years ago.

Before solar radiation and other forces in the universe killed its atmosphere, it was thought that Mars was similar to Earth in its early days. This explains why the wanderers who have now spread on the Twitterverse and other places in Jezero Crater (almost thought to have been a huge lake, may also crawl in the life of microorganisms) have been passed down. Now, scientists have found evidence that Mars has gone through the same stage as the Earth before both planets enter the atmosphere. This has not yet been confirmed.

Liu Jiancheng said: “Reduced greenhouse gases, such as methane (CH4) and hydrogen (H2), may be the only viable solution to explain the warming of ancient Mars, but there is a lack of direct geological evidence to show that there are indeed on Mars. Reduced atmosphere,”

; he led a recent publication in Natural astronomy.

The timing of this discovery was just right. Perseverance has begun to look for any possible signs of life on the red planet, and this life-if it is as we know it-will require an atmosphere. But wait. Before you figure out when Mars begins to form an atmosphere, and what the atmosphere is (it’s hard to imagine what space desert it is now), you must make further backups until it is oxidized. Sometimes things on Earth or Mars will not rust because there is not enough oxygen in the atmosphere to interact with iron-rich materials.

Both Earth and Mars once had a reducing atmosphere, not an oxidizing atmosphere. This is different from the massive reduction in the atmosphere experienced by the Red Planet after most of the atmosphere is destroyed by solar wind and other cosmic forces. The reducing atmosphere consists of most reducing gases, such as methane, ammonia and hydrogen sulfide, which are rich in hydrogen rather than oxygen. Humans will not be able to handle the breath of this poison. However, on our planet, there are some microorganisms driven by methane, so it is not impossible for Mars.

The reason why Mars was once habitable is its own greenhouse effect. Although greenhouse gases have been demonized on the earth, because human pollution has released too much carbon dioxide and other types of gases into the atmosphere, the right amount of these atmospheric gases is necessary to warm the earth sufficiently so that life forms can Flourish.

Previous research assumed that on Mars, this phenomenon occurred when gas was reduced instead of carbon dioxide, which meant that the Earth’s atmosphere must be reduced. Liu and his team finally found this evidence when investigating spacecraft data on rocks cremated by the spacecraft, which showed signs of exposure to this atmosphere.

Liu said: “The separation between the iron and aluminum in the ancient Martian soil is comparable to the trend observed in the ancient soil before the Great Oxidation event on Earth, indicating that the ancient Martian surface was chemically weathered in a reduced greenhouse atmosphere.”

The orbiter conducted remote inspections of rocks on the surface of Mars. The spacecraft is equipped with an instrument with an infrared spectrometer that reveals the chemical properties of these primitive rocks. When infrared light hits a target, it will interact with the molecules that make up the target. How the object in question absorbs, reflects or emits this light can release its chemical composition. What researchers want to know is the composition of ancient soil on Mars, which was formed a long time ago and is physically and chemically unrelated to the recently formed soil. This is how they determined the chemical signs of weathering caused by the reduced atmosphere.

Mars later experienced an oxidation event, which is different from the Earth’s major oxidation event on Earth, although the time of occurrence is different, and the cause may be different. Because oxygen is a by-product of photosynthesis and other processes in the early organisms, the earth’s atmosphere is oxidized. Proving that Mars has reduced the atmosphere before the oxidation event, which may mean that life has participated in the transformation in some way.

When Perseverance investigates Jezero Crater, more evidence may be found to support this discovery, perhaps even fossil microbes.
