New hope for the possibility of "life" on Mars

New hope for the possibility of “life” on Mars

The hypothesis of the existence of life on Mars is of great interest to astronomers because of its proximity to the Red Planet and its resemblance to Earth.

An analysis of images taken by the American Mars rover “diligently” confirms the appearance of the modern landscape of Mars, according to an article published in the journal Science.

It is noteworthy that when there was a lot of water on the planet, the water level in the abyss continued to fluctuate during the flood. Researchers at the time did not rule out the possibility of biological life on Mars.

Images coming from the orbit show the fan-shaped structure of Jessaro’s bottom. According to NASA experts, it looks like a delta – the place where the river flowed into the lake about 3.7 billion years ago. There, scientists plan to search for the remains of ancient Martian microbes.

Guide to Organic Compounds

In June 2018, the US space agency NASA announced that the Curiosity rover had taken samples from two different locations in a dry lake in the Bahramb Heights and found evidence of the presence of complex organic compounds from soil rocks about three and a half billion years old. Gale groove.

These rock samples, using the Mars sample analyzer on the Curiosity rover, after thermal analysis, released a group of organic molecules containing sulfur-containing aromatic compounds such as theophylline, benzene and toluene, as well as aliphatic compounds such as propane and butane.

The authors believe that the concentration of organic compounds was found to be 100 times higher than the previous measurements, and that the presence of sulfur contributed to the preservation of these compounds.

The releases of the compounds are similar to those derived from the fraction of kerosene, an organic compound that preceded oil and natural gas on Earth.

These results are not evidence of life on the planet, but rather NASA explained that there are organic compounds needed to stabilize the life of microorganisms, and since the Martian atmosphere can protect these compounds there may be deeper sources of organic compounds on the planet.
