The perseverance found a large number of organic matter, and Mars life is about to show up?Scientist statement
Author:Space -time communication Time:2022.09.21
Recently, the internationally renowned "New Scientist" magazine website reported that the perseverance detector found a large number of organic molecules on Mars. Organic molecules are the most basic carbon molecules composed of life, so scientists believe that Mars is more likely to have life.
A stone aroused thousands of waves. Human beings have been looking for out -of -life life for decades, searched throughout the solar system, and Mars' exploration has also launched dozens of detective spacecraft after decades. For more than ten years, I have not even found the hair of a life outside the ground. Now the hair of this life is about to appear?
Is the perseverance really so big? What kind of Mars car is it, it has been almost 600 days when it has reached Mars. What did you do? Let's find out together.
The perseverance is the most powerful Mars car ever in history
The perseverance is the fifth Mars car sent to Mars to Mars, which was first launched in 1997, which was sent to Mars. The number, opportunities, and curiosity. Now, except for the curiosity launched in 2012, the remaining Mars cars have retired.
Judging from the names of these Mars cars, NASA's exploration of Mars is tireless and full of passion and confidence. From the initial "living" to the increase of "courage", to the coexistence of hopes and "opportunities", and further "curiosity", to the "perseverance" adhered to now, it is continuously promoted.
The current perseverance is a enhanced version based on the curiosity. It is equipped with more advanced scientific loads and is the strongest Mars car in history. Different from the previous Mars cars, this time the perseverance brought a helicopter called Ingenuity, the nickname wisdom, the quality was only 1.8 kg, and it was hung under the belly of the perseverance.
This is the first time that humans have used air dynamic aircraft on the planet outside the planet. Relying on Mars, there is only a thin atmospheric flight with a density of the earth on the Earth, which creates a precedent for flying on -site planets.
There are several new breakthroughs in the perseverance: the heaviest Martian car ever, the quality is as high as 1025 kg; the first time on the alien planet uses the "air crane" method to shock the landing, and it is returned to the login image; Known as a powerful laboratory; equipped with 23 recording imaging equipment, including 9 engineering cameras, 7 scientific cameras, and 7 landing cameras.
The perseverance landed in Mars for seven months, and the miracles created one after another: the shooting returned the most spectacular Mars surface high -definition image, up to 2.5 billion pixels (above); 240 meters per second, about 70%of the speed of the earth; using Mars's thin carbon dioxide atmosphere to create oxygen for humans to breathe; for the first time, the Martian eclipse screen was taken and the image was passed back.
The data returned a few days ago shows that through the drilling and analysis of Mars sedimentary rock, the perseverance found a large number of complex organic elements containing the Fang chemicals, and was trying to open the door of Mars' life.
The task of perseverance is to inherit the front and explore Mars life
The task of perseverance is that on the basis of the four groups of Mars cars launched in the past, the focus of the past, mainly focusing on exploring whether Mars has life.
Prior to this, after decades of exploration of various Mars detectors and Mars cars, it was basically determined: there was water on Mars, but the state of frozen water in the ground and polar was existed; The earth is 1%of the thin atmosphere; the surface of Mars has the sea and river in ancient times.
Mars observed before and after the sand of the sand in July 1998
Because Mars is farther away from the sun, it is cold than the earth; Mars yellow and red tilt angle is 24 degrees, which is very close to the earth 23.44 degrees, so there are also four seasons all year round; Mars has been around 24.6 hours since the week, and a Mars day is similar to a earth day; Mars The revolution is about 687 days a week, about two years on the earth; Mars has two satellites, namely Fire Wei Yi and Huowei.
Therefore, Mars is considered the planet with the closest to the solar system and the earth environment, and is the preferred planet for future human immigrants.
However, because Mars is far from the earth and the earth is smaller than the earth, and there are many environments that are different from the earth: First of all, there is no air for human breathing; because there is no enough atmosphere and geomagnetic protection, the Mars surface is widely received by the sun. The invasion of the interstellar high-energy radiation; the temperature difference between Mars temperature reaches 160 degrees Celsius, the lowest temperature in the winter night can reach -133 degrees Celsius, and the maximum temperature of the equator in summer can reach 27 degrees Celsius.
Under such a condition, can life on Mars still exist, and how feasibility of human future immigration to Mars? This is a question that humans have always wanted to figure out. The perseverance is carried out the expectation of human beings. It will go to Mars, will exhaust themselves in their lives, and strive to give humans a clearer answer than ever.
As a result, it mainly does two things in Mars: First, by investigating the ancient environment and rock samples of Mars, to understand the characteristics of Mars ’s ancient climate, whether there is an overlush environment, reveal the process of its address, search for possible biological signals; Second, use the natural resources on Mars to test the oxygen and fuel required by human landing in Mars to explore the feasibility of human landing in Mars.
The perseverance lived up to expectations. A large number of organic matter was found in the sedimentary rock named Skinsa's ridge, and the analysis data was returned to the earth. Thomas Zubuchen, the head of the NASA science department, believes that these samples collected in the sedimentation area help explain whether Mars has the core issue of life. Scientists generally believe that although these substances are not the symbols of life, it means that scientists have found the right place. These rocks rich in sulfate and clay can well preserve biological characteristics. These substances may be taken from hundreds of kilometers from hundreds of kilometers ago.
So, does this mean that life is about to be discovered?
This conclusion seems to be too early. Experts from the NASA and the European Air Bureau said that in 2026, they will fire two unmanned spacecraft to Mars in 2026. One of them landed in Mars in 2028 and received the sample collected with the perseverance, and then launched the sample to Mars The orbit is handed over to another spacecraft waiting for the orbit. The latter returned after receiving the sample and sent the sample to scientists in 2031.
This will be the first time human beings traveling from Mars, a prelude to human landing in Mars, and a big show at that time.
Through fine analysis and research on the samples collected by Mars, scientists may be able to get evidence and inferences that do not exist on Mars. From this point of view, to solve the mystery of Mars's life, it is far away. However, the perseverance is still acting, and maybe more discovery will follow.
Now, the perseverance not only discovered the clues that may exist in life, but also used a device of about half a microwave oven in the size of a microwave. Moxie collects the thin carbon dioxide atmosphere of Mars, and 10 grams of oxygen can be created per hour. Although there are very few, it can only be used for a person to breathe for 20 minutes, but it is a shocking breakthrough. It declares that in the future, human landing in Mars can completely use the oxygen for breathing on Mars.
In the next step, it is necessary to use the freezing water that Mars has to create water that can be used for drinking, and use hydroxide in the water to create energy for spacecraft ~ methane. This is exactly the reason why the Starcraft of Musk Space X does not use a lot of other chemical fuels on the planet, but uses methane as a fuel. Musk, who wanted to send humans to Mars, had long been prepared to use Mars resources to create a round -trip fuel.
The perseverance has been working lonely on Mars for almost 600 days. Its design life is only 1 Mars year, which is 687 days. So is the perseverance going to live? I don't think it is because its predecessors are far greater than the design life. For example, the design life of the courage and the opportunity number is 90 days, and the results have been done for 7 and 15 years respectively; the curiosity design life is 1.88 Mars year. As a result, it has been working hard to work since 2012.
There are so many senior examples incentive, I believe the perseverance will be more "perseverance." In addition to the perseverance on Mars, there are also curiosity and our country Zhu Rong working for human beings silently. Let us take this opportunity and sincerely wish these human AI friends, work smoothly, healthy and longevity! What do you think, welcome to discuss and comment.
