The scientists have just discovered the longest organic molecules. But also blessing from Mars, the fourth planet from the sun and a talisman for the search of humanity.
Mars today are hospitable. There is a fluctuation of important temperatures, thin atmosphere and clear liquid water on the surface of the world. But from a new research Published Today, in the operation of the National Academy of Sciences, a large molecule found in Mars is obvious that life is like a life in the world.
The molecule is a long carbon chain that has up to 12 carbon atoms. The molecules are sitting on Mars for about 3.7 billion years, without disturbing geological activities, moisture or heat. The same day molecules A well -known signal or life On our planet
The curiosity of Mars for many years revealed the new details of the world. Ancient environment– The key to the environment is carbon, the element that is important to life and is useful for molecules, including DNA and RNA. From the launch of the French Scientific Research Center (CNRS), the launch of the carbon chain “can show similar properties to the fatty acids produced on the world by biological activities”.
The discovery of these organic molecules presents important in -depth information about biological processes that may occur in early March. But in order to be clear, not evidence of life in the past or present However, what I tell us is to create a blog that is necessary for life that we know that it exists – and Mars may have the right conditions to support.
“Although these sources of organic molecules cannot be created in this study But these organic substances may occur in both geological processes on Mars. (Non -biological chemical reactions, such as from hydrothemol activities), meteorite or they are organic scraps of ancient Mars. “Daniel Glavin, senior scientist for a sample of NASA's Goddard Space Center and the author of the email to Gizmodo.
The team, which includes scientists with CNRS and many other institutions have discovered using a sample analysis at the Mars (sam) laboratory on a curious boat. SAM has gas, gases, grills and mass meter, which allows separate molecules in the examples collected by a landing car. Curculation Happy organic matter In the previous Mars rock But the new research explains the longest chain that is still specified Searching for long carbon chains on Mars is important because it shows that NASA's scientists are in the right path that they search for signs of life – at least the things that have been lived on earth.
The curiosity is still strong. But the successor of the mission of the past in March is coming. Esa's Exomars Mission set to launch in 2028 and NASA-ESA together. Example of Mars's return The mission will help scientists assess the composition of Mars in the past – and the potential of ancient life on its surface.
“The discovery of long -haired hydrocarbons that have been preserved (And not completely destroyed by contact with ancient Iorce radiation) in ancient sediment on Mars Living in the world, “GLAVIN added,” From the meteorite analysis and examples returned from the asteroid Bennu and Ryugu. OSIRIS-REX and Hayabusa2 missions. (Used to create protein). Carbic acid Nucleobases (DNA and RNA and RNA components) are solar widows and chemical creation units will be sent to March. “
“But a million dollar questions: chemicals that create life from the creation of these basic chemicals into a large and more complex structure, such as protein and nucleus found in the cells that have occurred on Mars?”
The liquid water used to be in Vaste and Lake on Mars. Now it has been dry for a long time. Rover is assigned to explore the environment that once was looking for signs of fossil life, similar to the wet act of the world. Scientists have seen Sign or liquid Under the surface of Mars, although the discovery of speculation must be checked more before scientists speak for sure.

The model of Sam in NASA also starves the photos: Caroline Freissinet.
In the year 2023, it was found that the Land Rover Car Organic molecules preserved On Mars – not confirmed that life has been on the red planet. But is an indicator that encourages the conditions for our lives
New method It is easier to see the signs of life in March and may explain that the life that may have once disappeared when the red planet became Be sterile and unfavorable–
Beyond MARS CNRS launches that the same international team will create tools such as Sam for dragonflyQuadcopter to explore the Titan satellites of Saturn began in the middle of the 2030s.
