Rover Interest of Nasa Has achieved discovery in an unprecedented way for detecting Compounds Identified the larger Marte. This invention was published in the press Activities of the National Science AcademyS (PNAs), advises it Prebeanic chemistry May be more advanced than the Red planet believed.
Scientists analyzed and found the extracted rock samples with the mini -pad sample analysis of the mars of interest (SAM) Three main molecules Teen, Antocono and Tottechan. These compounds are formed by chains 10, 11 and 12 carbon atoms respectivelyThey may be pieces of fatty acids protected on Mars.
In EarthFatty acids are essential for life because they are part of Cell membrane. However, without biological intervention, they can be developed by chemical reactions triggered by geological processes, such as water contact with minerals in water heating sources.
Although it is not yet determined if these compounds are A biological appearanceMars refers to a better step in searching for complex molecules that can be the forerunners of life.
The most complex organic molecules
Until now, curiosity has found small and simple organic molecules. The first proof that Mars has reached the level of organic chemicals to identify large compounds The origin of life. This discovery also strengthens the opportunity to be called more complex organic molecules Biofirmas, Mars is protected on the planetDespite the extreme radiation and oxidation that affects the surface of the planet.
Scientists examined these compounds in a rock model Comparland.
Cumberland model contains clay minerals, which are formed in water, as well as High sulfur levelsAn element that helps protect organic molecules. In addition, it contains nitrates, is essential for life on earth, and gas related to biological processes on our planet.
A wonderful invention
Although the appearance of these molecules cannot be firmly confirmed, the invention encourages the interest group. “Our study shows that when analyzing samples of Mars, even now, we can find The traces of chemistry of past lifeIf it was occasionally on Mars, “Caroline Freescent, a researcher of the French National Science Research Center (CNRS) and a prominent editor of the study.”
This invention strengthens the idea of the future tasks that Mars samples can bring to Earth Providing definitive evidence About the possibilities of living at some point in the history of Mars.
