Signs of life are not found on Mars, research done on Earth told why

Science News Desk – The matter is not new. Looks like the same story again! But this time there is a new twist in the case. So this is the case for the search for life on Mars. But the story is the same. Right now the conditions are unfavorable for life on Mars. That’s why NASA’s Perseverance rover is roaming there looking for signs of life beneath the surface. But a new study has brought a new twist to this story by saying that there is a very simple reason why there is no life on Mars and that is the inefficiency of the rover! Yes, we are talking about this twist in the story which is creating a new story.

the situation is very bad
If we look at today’s Mars, the atmosphere is very thin and what is there is full of carbon dioxide. Most of the surface remains at a temperature well below zero. For a very short time (not days) the temperature reaches 5 to 15 °C. Forget liquid water, even if you get it, you will get ice. That is, if there is life, it cannot be lived far away.

all hope
In such a situation, scientists have not given up hope of getting signs of life on Mars, for which they have many reasons of their own. Their biggest hope is that they can find life or signs or evidence of life beneath the surface of Mars, and the rover is looking for microbes beneath the surface there. But the new study says its tools are not up to the task.

current technology is not enough
In this study scientists have shown in Earth’s oldest desert that current technology cannot always find signs of life beneath the surface of our own planet, let alone Mars. Scientists engaged in this investigation have argued that without the development of the ability to detect long-dead microbial dark matter, the question of life on Mars will remain muddled.

Looking for signals billions of years old
This is especially the case when we are looking for life that existed billions of years ago when the planet was much warmer and wetter than it is today. In the Atacama Desert of Chile, there is an old delta named Red Rock with sand mixed with mudstone and hematite rich rocks. Geologically, this region is similar to many parts of Mars.

riddle of mysterious signs
This is why astronomers use this spot as a model for the Red Planet. When researchers studied the mineralogy of Chilean redstone with the best tools available today, they found some mysterious clues. Nine percent of the genetic sequence obtained from Next Generation Sequencing was found to be of unclassified category while 40 percent could not be placed in any specific category.

Researchers from the Autonomous University of Chile say their investigation revealed an unusually high level of phylogenetic uncertainty. To characterize the uncertainty, the team has proposed a new concept, which they are calling the dark microbiome. It refers to microorganisms that scientists have identified through genetic sequencing, but they do not know exactly who they are.

Researchers say that these organisms may be completely unknown species of organisms that have not been found anywhere else, nor do they have any information in today’s sequencing databases. The same technique is being used on Mars, which shows that in most cases nothing will be detected. Where last year there were signs of biological material in Perseverance. Curiosity also found signs of organic matter. But organic matter is not a sign of life. But it could not be ascertained whether they had any biological origin or not. At the same time, our analysis will largely depend on the samples from Mars.
