Curiosity finds new carbon molecules on Mars. What does foreign life mean?

Kurianity Marsiity Mars found the larger organic (carbon containing) molecules found on the red planet. Discover is one of the most important findings to find for evidence of past life on Mars. This is because, in the world however, somewhat complicated, carbon molecules long-chain involved in biology. These molecules can be fragments of fatty acids, for example, for example, the membranes surrounding biological cells.

Scientists think that, when life comes out of Mars, it may be microbial in nature. Because the germs are too small, it is difficult to understand any potential evidence for life to see in Mars. Such evidence requires more powerful scientific instruments that are larger than a rover.

Organic molecules found by curiosity consisting of carbon atoms involved in upper chains, with other elements tied them, such as hydrogen and oxygen and oxygen. They come from 3.7-billion years of stone called Cumblland, meeting the rover in a major dry size of the crater. Scientists use the Sample Analysis on Mars (Sam) instrument on the rover to make their discovery.

Scientists actually seek for evidence of amino acids, which are the blocks of construction of proteins and therefore key substances in life as we know. But this unexpected search is almost as fun. The research was published in National Academy of Science Prompts.

Among the molecules are decede, with 10 carbon aoms and 22 hydrogen aoms, and dodecane, with 12 carbons and 26 hydrogen aom. It is known as alkanes, falling under the umbrella of chemical compounds known as hydrocarbons.

This is an exciting time to find Mars life. In March this year, scientists Presented evidence In parts of a different sample stone elsewhere in Mars by patience rover. These parts, called “leopard spots” and “poppy seeds”, can be made by moving microbial life in distant past, or not. The findings are presented at a US conference and have not been published in a journal of a peer.

the Mars Sample Return Mission, a collaboration between NASA and the European Space Agency, offering hope that samples collected in the stone collected and kept by maintaining the laboratories. The powerful instruments available in terrestrial labs can be confirmed if there is clear evidence for the past life of Mars. However, in 2023, one Independent Review Board Criticized the increase in Mars Sample Rovect budget. This prompts agencies to re-change how the mission is made. They now study Two Changed Options.

Signs of life?

Cumberland was found in a Gale Craner region called Yellowkife Bay. This area contains stone formations looking pretty suspicious as those formed if sediment establishes under a lake. One of the scientific purposes of curiosity is to investigate Mars events suitable for life’s progress, so an ancient lakebed is the perfect place to seek them.

Researchers think alkane molecules can contain components of more complex molecules of fatty acid. In the world, fatty acids are fat and oil components. It is made by biological activity in processes that help form cell cell membranes, for example. the Suggested Presence In fatty acids in this stone sample for years, but new paper detailed perfect evidence.

Fatty acids are height, linear hydrocarbon molecule with a carboxyl group (cooh) at one end and a charmy group (CH3) of a rugged carbon and hydrogen atoms.

A fat molecule consists of two main ingredients: glycerol and fatty acid. Glycerol is an alcohol molecule with three carbon atoms, five hydrogens, and three hydroxyl (chemically corded oxygen and hydrogen, oh) groups. Fatty acids can have 4-36 carbon atoms; However, most of them have 12-18. The longest carbon chains found in Cumberland is 12 atoms long.

Mars Sample Return

Organic molecules stored in ancient Martian rocks provide a critical record of the previous Mars’ pillar-ons and can signs chemical bids (signs that life was).

The sample from Cumberland analyzed Of many Sam’s instruments many times, using various experimental procedures, and show evidence of clay minerals, as well as First (small and simpler) organic molecules Found on Mars, back in 2015 The new discovery doubles the number of carbon atoms found in a mars molecule.

Alkane molecules are important in searching for biosigns on Mars, but how they actually formed remain unclear. They can also be obtained by geological or other chemical mechanisms that do not include fatty acids or life. It is known as Abiotic sources. However, the fact that they exist today in the samples that are exposed to a violent environment for many million astrobiologists (scientists who are studying the life outside of the earth) hope that evidence of ancient life can still be found today.

It is possible that the sample contains even the upper chain of organic molecules. Can also contain many complex molecules that indicate life, rather than geological processes. Unfortunately, Sam is unable to discover, so the next step is to deliver the stone to Martian and the earth with the most competent laboratories in the world. Mars Sample samples will do it in samples that have been compiled by patience on Mars Rover. All that is needed today is the budget.
