The curiosity of NASA March Rover find out The largest organic molecules (containing carbon) are absolutely present on the Red Planet. This discovery is one of the most important results in searching for evidence of past life on Mars. This is because, at least, at least, the carbon molecules with a relatively long chain in biology shares. These molecules can actually be fragments of fatty acids, which are found, for example, the membranes surrounding biological cells.
Scientists believe that if life appears on Mars, it is likely to be microbial in nature. Since the microbes are very small, it is difficult to be final about any possible evidence of life on Mars. This evidence requires more strong scientific tools that are very large so that it cannot be placed on a Rover.
The organic molecules of curiosity consist of carbon atoms associated with long chains, with other associated elements, such as hydrogen and oxygen. They come from a 3.7 billion -aged rock called Campeland, and it faced Rover in a supposed dried lake in the Mars hole. Use scientists The sample analysis in the Mars Tool (SAM) On NASA Rover to discover them.
Scientists were already looking for evidence of amino acids, which are protein blocks and thus the main components of life as we know. But this unexpected discovery is almost exciting. The research has been published in The facts of the national academies of science.
Among the molecules that Decan, which contains 10 carbon atoms and 22 hydrogen atoms, and Dodican, with 12 carbon and 26 hydrogen atoms. These are known as Alkanes, which are under the umbrella of chemical compounds known as hydrocarbons.
It is an exciting time to search for life on Mars. In March this year, scholars Evidence provided From the features in a different rock, samples were taken elsewhere on Mars by perseverance. These features, called “leopard spots” and “poppy seeds”, can produce by making microbial life in the distant past, or not. The results were presented at an American conference and has not yet been published in the Journal of Laysee.
