The amount of organic carbon that is comparable to some land area
In 2014, A series of experiments were carried out to measure the fraction Total organic matter on Mars. After eight years of data analysis, the results are finally available in the journal Reveals that the rocks of Mars are relatively rich in organic carbon, which is one of the key components for the launch. Prebiotics and possibly The Of Biology.
It has been some time since scientists discovered traces of organic carbon . But evaluating its availability is an important parameter that determines the growth potential of life. And the results are surprising because the rocks on Mars show a significant portion of organic carbon, comparable to some landforms. Admittedly, the values are the same as the values of the reduced harsh environments in organic carbon. Landscape), as , But these are encouraging results for Mars. Because it shows that there is enough carbon available for construction (comment) It is the basis of all life forms known to date.
Water, carbon, energy sources … all the things in life together
Is defined as the amount of total organic carbonCarbon bound to organic molecules (usually made up of atoms) Of And nitrogen). If most of the organic carbon on Earth is of biological origin, it may be of non-biological origin, especially , Volcanic activity or certain chemical reactions on the surface of the planet. Since Mars has organic carbon, there is no way to prove that life originated on this planet.
With liquid water, the significant amount of organic carbon on the other hand is a new element, indicating that the basic materials needed for life existed on Mars a few billion years ago. Curiosity would have been the gale groove that formed Besides water and carbon, there are other essential elements in the environment: Sources Low acidity, oxygen, nitrogen and .
So the curiosity to find the first clues of the searched Mars life may be in the right place. However, if they were, accessing them would be harder than we thought.
Review the search strategy for organic molecules such as amino acids
A new experiment was carried out byTo actually get a chance to detect organic molecules, the rover would have to drill to a depth of two meters in the bottom of Mars. This is especially true of search It may or may not have a biological origin, but it is considered a building block for construction in all cases . However, the Amino acids are brittle and easily destroyed The thin reaches the surface of Mars Does not provide effective protection. Currently, the rovers are drilling to a depth of five centimeters. At this depth, scientists estimate that amino acids are destroyed in just 20 million years. Knowing that life on Mars may have formed billions of years ago, it would seem utterly useless to explore this superficial scale.
These results were published , Show the need to implement a new search technique for rovers currently in operation, which unfortunately do not have the facility to drill to the required depth. Need to find a solution Because of the recent revelation of deep areas such as small impact craters less than 10 million years old or materials expelled from such craters.
