NASA refutes the claims of former employees, denying that life has been found on Mars, but is there

NASA denied the claim of former employees of Scientific American Gilbert Levine that "life on Mars has been discovered." On Oct. 16, NASA published a blog post on Scientific American denying the former employee's claim in a statement to Xinhua that life had been found on Mars. Gilbert Levine, a former NASA employee, said in a blog post titled "I'm Convinced We Found Evidence of Life on Mars in the '70s" that the results of the Martian microbial experiment should be seen as evidence of life on Earth today.

As astronomer Carl Sagan said, "unusual claims require unusual evidence," and the general consensus among scientists is that the results of this experiment are not unusual evidence in themselves, NASA spokespeople said.

At the recent inaugural appointment ceremony in Beijing, the academician of astronautics and lunar exploration was appointed chief designer of China's manned space program and chief expert in space science. Gu Yidong, chief designer of aerospace engineering of the Chinese Academy of Sciences, director of the Aerospace Application Engineering Technology Center of the Chinese Academy of Sciences, and researcher of China's manned space program, hired Wang Zhonggui, Yang Liwei, Chen Shanguang, Zhou Yanfei, Liu Jin, Deng Yibing, Deng Yibing, and Zhang Peinan, chief experts of China's manned space program, to be the deputy chief designer of China's manned space program.

At present, the chief designer and deputy chief designer of the manned space project are selected and appointed, and at the same time, the chief designer system management mode, the structure of the chief designer team and the major adjustment and optimization of force innovation, the engineering department and the entire system are oriented to the widely selected chief designer, deputy chief designer, engineering department and astronauts, space stations, spacecraft, launch vehicles, space applications, launch sites, TT, etc.

I don't think so, with our current science and technology, we have not found any life on Mars.

I think there's probably life on Mars, it's just that we don't have it yet.

According to the current research and exploration, there is no life on Mars, so there is no life.

There should be no life on Mars, but there is also the possibility of accidents.

There should be no life on Mars. It's just human speculation.

I think there should be no life, because Mars has no matter to indicate that life existed.

It should be lifeless, after all, the environment of Mars is not suitable for life at all.

This must be a state-level secret, and it is impossible for us to know.

I think there should be this, but it's really hard to say.

Mars is actually lifeless, and the environment on Mars is not suitable for life at all.

American scientists: Traces of life on Mars were found 40 years ago.

Before discovering traces of life, NASA's Curiosity rover was exploring Mars and found traces of saltwater lakes on Mars, and it was likely that there was Martian life hidden inside.

This saltwater lake on Mars is located near the famous Gale crater on Mars, and by analyzing the sudden samples collected in the Gale crater, American scientists have found that it contains various salts, and the sulfate in it has been confirmed to be something left after the water evaporates, which proves that there was an ancient saltwater lake here a long time ago.

Scientists have long discovered that Mars was a warm and humid planet 3.7 billion years ago, but in the time that followed, suddenly some kind of drastic change in the climate caused Mars to become arid. This discovery confirms this once again.

On Earth, there are many different biomes in saltwater lakes like this, so it is very likely that there is similar life in the saltwater lakes on Mars, and even if these lives are now gone, it is very likely to find clues that these life existed, such as various fossils. Scientists don't have the ability to go deeper underground on Mars, but as Curiosity looks deeper into the Martian surface, there will be more surprising discoveries. I believe that one day, mankind will be able to discover the secret of Mars becoming what it is now, which will also be of great help to mankind to grasp the earth's climate change.

The Earth's climate has changed dramatically compared to before. For many wild animals, the current global environment is becoming more and more unsuitable for their survival, because they cannot adapt to the changes in the environment, and they are gradually disappearing. The impact of the earth's environment on human beings is also great, and if the species on the earth are further extinct, the earth's biosphere may be greatly damaged, and then human beings will inevitably suffer the consequences.

Regarding whether there is life on Mars, there is no sign of human existence on Mars, and there is no information on this, because although Mars is suitable for human conditions, it still cannot live on people, so there is no life on it now, and there is no life on it.

Ask if there is life on Mars.

Answering the question of life on Mars, scientists have been studying whether there is life on Mars for thousands of years. Now, space experts have pointed out that there is a huge amount of frozen water under the surface of Mars, and that water is the source of human survival. With the continuous development of science, Mars has the potential to become a second Earth suitable for human survival.

In 2016, scientists discovered the first moving sand dunes in the Snake River Plain in eastern Idaho, very similar to those found by the Mars Reconnaissance Orbiter near the Hellas impact crater, a finding that reinforces the idea that Martian dunes could host life. With a height difference of 75 meters at the edge of the Hellas impact crater, it is a huge ghost dune that has existed for a long time, so it is possible that there was Martian life.

Ask a good question. AnswerFor the earth, there is an underground ecosystem of inorganic trophic microorganisms on the earth, in which microorganisms obtain energy and survive by stripping electrons from surrounding molecules. Hydrogen is a good electron donor, which can provide energy for underground inorganic trophic microorganisms. According to a new study, such an underground microbial ecosystem may have existed on ancient Mars, because 4 billion years ago, there was enough hydrogen on Mars for underground microbes to thrive, so life may have existed.

Hmmm, I hope it helps.

At present, human exploration of Mars is in its infancy, and it is not completely certain whether there is life on Mars.

Whether there is information on life the day after tomorrow, there should be the above information the day after tomorrow, because Huo Ting is also a kind of. She should use an inch of space for the things she obtains, so she uploads the information again.

: There may be, because there are various signs that there was water on Mars, and water is the source of life, so there is a high possibility of life on Mars, but because Mars no longer has the conditions for life to survive, and according to the current level of detection, no signs of life have been found, so there is no life on Mars.

Whether there is life on Mars or not has not yet been proven, no one can say clearly, and no one can say for sure.

This is a subject of research by scientists, and now humanity is launching a Mars program.

Should you go to the bookstore to find encyclopedias, alien tired Mars, whether there is life, and you can find similar readings?

You've got that morning shift, but you know it's easy to find one.

Scientists have found some signs that liquid water can exist on Mars. One of the most striking pieces of evidence is that the polar surface of Mars appears to be full of cracks and striated structures, and the location, shape, and distribution of these sensitive voids are associated with flowing water. In addition, the probe found some sediments on the surface of Mars, which also indicate that there may have been liquid water flowing in the past.

Although no probe has directly observed liquid water, these indirect evidence suggests that liquid water may have existed on the surface of Mars or that some underground water sources still exist. This is very important for finding signs of life, as all known life needs water to survive.

There is no conclusive evidence of life on Mars. However, scientists have been searching for clues about whether there is life on Mars and have already found some exciting signs.

For example, there may be liquid water on Mars that I mentioned earlier, and all known life needs water to survive. In addition, there are some subterranean rock formations on Mars that may be able to protect life from radiation and other harmful conditions. In addition, some past detectors have discovered some organic molecules, which are essential chemicals for the formation of life.

So, while we don't yet have conclusive evidence of life on Mars, ongoing scientific exploration and research are bringing us closer to the answer to this question.

Yes, indeed, because some footprints have been found on Mars, and it is likely that these footprints are due to the presence of some other life.

Appeared. In the magazine, scientists claim to have found traces of life. And some relevant data was also sent back.

There should be no life on Mars, because no life has been detected on Mars.

It's not certain yet. Because of our current technology, the exploration of Mars still has certain limitations.

There is no clear evidence for the existence of life on Mars, but scientists have found evidence of liquid water on the Martian pants.

Over the past few decades, humans have explored Mars several times and found many traces of rivers, glaciers and water on its surface, as well as many blue rocks and soils, suggesting that they were once eroded by water.

In addition to this, some scientists now believe that there may be liquid water lakes on the lower surface of Mars today, and they have discovered many mysterious lakes where the liquid may be water.

Although there is no conclusive evidence of life on Mars, the following aspects may indicate the possibility of life on Mars:

Evidence of liquid water.

1.Presence of water: Water is necessary to support almost all life forms on Earth, and traces of liquid water have been confirmed on the planet, which may indicate that life on Mars can adapt to different temperature and pressure conditions, and that water-based life forms may exist.

2.Presence of organic matter: Organic matter is a carbon-containing compound, including life or its remnants, and some recent probes have detected some carbon-containing molecules on Mars, which may indicate that there was once organic matter on Mars, or the possibility that organic matter still exists.

3.Relatively stable climatic conditions: Mars' surface temperature and pressure conditions are relatively stable relative to other planets, which may mean that life forms adapted to this environment will be more likely to form and develop than life forms adapted to other planets.

Relatively stable landforms.

4.Relatively high geological diversity: The terrain on the surface of Mars is very complex, which may indicate that it once had geological features similar to those of the Huxiang file on Earth, such as rivers, oceans, and volcanoes. These geomorphological and geological settings may have provided the conditions for the origin and existence of life.

However, despite the presence of liquid water, there is currently no reliable evidence of life on Mars. But researchers are still looking for possible signs and evidence of life, and Mars may be an important destination for our future exploration of life.

It also needs human exploration and proof.
