In the future, China will implement Mars sample return, and when will it be carried out?

Specifically, we will have to wait until our country has finished studying the moon, but the time is also fast, maybe two or three years later.

According to the report, we will carry out Mars sampling and return when the relevant technology is more mature, because the environmental composition of each planet is very different, and we must make the technology fully mature and reliable in order to achieve sampling.

The specific time has not been announced, but Wu Yanhua, deputy director of the China National Space Administration and deputy commander-in-chief of the lunar exploration project, said that the first Mars exploration mission "Tianwen-1" is on the journey of "running for fire"; Engineering tasks such as asteroid exploration, Mars sample return, and Jupiter system exploration will also be implemented as planned.

Xu Hongliang, spokesman for the China National Space Administration, said at the meetingChina will be inAround 2025, the mission of near-Earth asteroid sample return and main-belt comet orbiting will be carried out; Around 2030, the Mars sample return mission will be implemented；This will be followed by Jupiter orbiting and interplanetary crossing.

In terms of lunar exploration, during the 14th Five-Year Plan period, China will launch the Chang'e-6 and Chang'e-7 probes to carry out environmental and resource exploration in the lunar polar region and sample and return of samples in the lunar polar region. Chang'e-8 will be launched later.

In terms of manned spaceflight, by the end of 2022, China will build a long-term manned space station to carry out long-term residence of astronauts, space science experiments, and space station platform repair and maintenance.

Tianwen-1 was originally planned to be only "orbiting".

Being a guest on Mars is very difficult. So far, the overall success rate is about 50%; For landing missions, the success rate is only about 40%. China's first Mars exploration mission completed the "orbiting and landing patrol" at one time, which is extremely difficult.

At the press conference, Zhang Rongqiao, chief designer of China's first Mars exploration mission, revealed a little secret: the original plan chose a relatively small risk, that is, a plan to orbit.

But we are reluctant to this plan. Zhang Rongqiao said, "Compared with foreign countries, we started late. In the case that there is still a big gap with foreign countries, we have a basic consensus when we demonstrate:

We should not only consider the risks, but also consider the traction and driving role of the development of aerospace technology and scientific research. ”

After analyzing various factors, especially the manned spaceflight and lunar exploration projects that have laid a certain foundation of technology and equipment and facilities, and the Long March 5 carrier rocket providing the necessary launch capability, experts believe that although it is very difficult, the risk of "tiptoeing and stretching out your hand" to achieve a one-step orbit is controllable. As a result, the overall development idea of China's Mars exploration has been formed, which is to realize the orbit in one step and complete the sampling back in two steps.

The above content refers to Phoenix.com-China plans to implement Mars sample return around 2030.

According to the plan, China will carry out the first Mars exploration mission this year. According to the press conference held on December 7, the press conference of the National Information Office publicly announced for the first time that the Mars exploration mission "Tianwen-1" is on the journey of "running for fire". This means that in the future, China will implement the return of samples on Mars.

The two "firsts" themselves directly highlight part of the significance of this mission. Human beings are constantly changing the world and the vast universe as we know it through their current level of cognition. In a series of exploration activities, innovative and practical methods are used to make divergent thinking and observation perspectives more and more extensive.

The availability and knowability of all the world's materials are constantly giving impetus to people to explore the mysteries of the universe on earth. Therefore, under this development trend, it will be of great significance for China to implement Mars sampling and return in the future.

Mars is similar to Earth's. Mars has been hailed by scientists as the "Pocket Earth". To explore the understanding of the moon is, on the one hand, to know the moon itself, and on the other hand, to know the earth itself.

The same is true for human exploration of Mars, and some scientific studies have shown that it has a great similarity with Earth. Mars is closer to Earth. The Mars rover's observations show that Mars is now a withered, cold, and very dry planet, but its history is a great reference for us.

More than 4 billion years ago, this planet seemed to be the elder of the Earth, and like the Earth, it has a warm climate and abundant moisture. So people speculate that there may have been oceans on Mars many years ago, or maybe it was like Earth, and life made it vibrant. And the abrupt change in the historical stage eventually evolved into the appearance of history.

Therefore, the exploration of Mars will help us protect the Earth.

To summarize the above, the purpose of China's Mars exploration is to promote our in-depth understanding of the earth we live in by understanding the samples of Mars, indirectly understanding the climate and geological conditions, etc.

This is of cross-era significance for China's Mars exploration research, which can help us gradually understand the specific composition differences between different planets.

First of all, it shows that China's deep space exploration and asteroid exploration have made great progress, and there are round-trip tickets. It has provided support for the scientific exploration of Mars. Make our country the first echelon of Mars exploration. At the same time, it is also ready for landing on Mars.

This will help China to study the landform, topography and magnetic field of Mars, and improve China's comprehensive strength.

Engineering tasks such as asteroid exploration, Mars sample return, and Jupiter system exploration will also be implemented as planned.

On December 17, 2020, the State Council Information Office held a press conference on the Chang'e-5 mission of the lunar exploration project, in which Wu Yanhua, deputy commander of the lunar exploration project, mentioned that "China will implement Mars sample return in the future".I am pleasantly surprised and relieved that my country's aerospace industry has become so strong, and the five events of Chang'e-5 are China's first, which is enough to prove that China's aerospace technology has ranked in the forefront of the world. The global scramble for Mars has begun, the UAE's "Hope" and the United States' "Perseverance" are expected to land in 2021, so my country will definitely not lose with such technology, this is the moon's lead, Mars is not behind, and the whole can be said to be far ahead.

Starting from the complete success of the Chang'e-5 mission, it is understandable that the Mars exploration mission will be launched and the plan will be announced, especially thenThe samples and data brought back from the moon are not shared with the United States, which is a great pleasure! I feel that the announcement of the topic of "Mars sampling" also has the meaning of slapping the United States in the face, and I am proud of it anyway! The Mars probe "Tianwen-1" is still on its way to Mars, followed by Chang'e 6, 7, 8, asteroid exploration, etc., these achievements and data NASA you don't have a share, continue to slap your face!

Putting aside international issues, exploring the universe is a major proposition for all mankind, and exploring Mars is the starting point for exploring the entire universe. Exploring the universe is very significant for the development of the whole society and other aspects such as science and technology, and the resources and space of the universe are there, depending on how you get them. WhileMars is the most suitable planet for human exploration, and various studies have shown that Mars had water in ancient times, so is it possible for it to become a habitable planet?

In the short term, Mars is the preferred target for "migration" after the depletion of Earth's resources, and the return of samples is only the first stop of "migration". In the long run, Mars will be a stepping stone for mankind to conquer the universe!

There is a lot of ice at the poles of Mars, and humans have not returned samples from Mars so far! The position of Mars is the same as the position of the Earth from the Sun, whether Mars is suitable for human life, these puzzles will be solved, let's look forward to it!

It is very supportive, and very optimistic, it can be realized, with China's current science and technology, even if it cannot be done now, it can be done in the future, which requires the efforts of scientific research workers.

I think our country is really amazing, and as a Chinese, I am really proud.

It is very difficult to take out the soil from Mars, such as communication problems, temperature problems on Mars, how to take soil, and how to land.

I think the most difficult thing is the fuel problem, because Mars is farther away from us, so we have to have enough fuel to get to Mars safely, and there is no such fuel that can solve this problem.

The internal structure of the equipment, the design of the internal structure is actually very difficult, and the second is the issue of energy, which must take into account the energy supply in the universe.

On the afternoon of December 17, the State Council Information Office held a press conference on the Chang'e-5 mission of the lunar exploration projectThe fourth phase of China's lunar exploration project and the planetary exploration project will be implemented one after another.

At present, the first Mars exploration mission, Tianwen-1, is on its way; Chang'e-6, 7, and 8, asteroid exploration, Mars sample return, Jupiter system exploration and other engineering tasks will also be implemented as planned.

At 1:59 a.m. on December 7, China's Chang'e-5 returner successfully landed with lunar samples, and the mission was a complete success. This major achievement is a great encouragement and spur to all the scientific and technological workers participating in the research and test. For the first time, the sample return of extraterrestrial objects in China has been realized.

Following the return of lunar sampling, China will also implement measures such as Mars sample return, Jupiter system exploration, December 17, at the press conference held by the National Information Office, Wu Yanhua, deputy director of the China National Space Administration and deputy commander of the lunar exploration project, said that the first Mars exploration mission "Tianwen-1" is on the journey of "running for fire"; Engineering missions such as asteroid exploration, Mars sample return, and Jupiter system exploration will also be planned for implementation.

Mars sample return is feasible to a certain extent, and at the level of China's space technology reserves, it is already becoming more and more developed. Scientists say it will take at least a decade for the first primordial samples of Mars to reach Earth, and from now on it is important to be well prepared for this great mission. As of July 29, 2020, only the United States has landed on Mars.

China plans to officially launch the Mars probe for the first time in July this year, and it is expected that after 10 months of flight, it will arrive on Mars in 2021, land on the surface of Mars and conduct patrol exploration. After that, a second Mars exploration mission is planned around 2028 and Martian soil will be collected and returned to Earth.

The exploration of the Jupiter system, as far as China is concerned, is still in the research stage, and the road to exploring Jupiter is difficult, but it can stimulate the potential of aerospace scientists. Jupiter is a giant planet, and in the process of exploration, there is a certain amount of risk, and relatively speaking, the risk will be greater.

If these two measures are successfully implemented, it will be another major achievement in the history of China's aerospace industry, and I believe that we will definitely succeed!

I support this kind of detection very much, and at the same time, I am very proud that the motherland has such a strong technology and strength.

This represents China's major achievements in satellite exploration, and also represents the complete success of China's first satellite exploration.

This is a necessary work for the future development of science, and after completing these works, it can help us better explore unknown planets.

On December 17, 2020, the Chang'e-5 returner returned to Earth with lunar soil. This is the first time that China has successfully brought back a sample specimen from a celestial body outside the earth. This is also the second time in the world that lunar soil has been retrieved from the moon since the United States retrieved it from the moon in 44 years.

This means that mankind's understanding of extraterrestrial objects will be further advanced and their understanding will be more adequate. According to the news, China will also carry out Martian soil sampling and return in the future, so why do we need to study the soil of other extraterrestrial objects? I think there are several main reasons for this:

First, the full study of extraterrestrial celestial bodies is conducive to the future migration of human beings First of all, according to scientific research, the earth's resources are limited, a considerable part of the earth's resources are non-renewable resources, and the growth rate of human beings is much higher than the rate of regeneration of the earth's resources, so one day in the future, the earth's resources may be exhausted, and human beings need to find another planet that can live. Therefore, a full study of extraterrestrial objects can help us to compare the differences and similarities between celestial bodies, which is conducive to the great migration of humans in the future.

2. The full study of extraterrestrial celestial bodies can enable mankind to have a deeper understanding of the universe. Until now, mankind's understanding of the universe has been limited to the solar system. In fact, the universe is vast, and our knowledge of the universe is extremely small.

Therefore, the study of soil on extraterrestrial bodies can deepen our understanding of other planets in the universe, compare the differences between other celestial bodies and the earth, and then move from the solar system to the Milky Way and into the vast universe.

3. Exploring whether there are aliens The third point is a cliché, Hawking said that there will definitely be aliens in this universe. Therefore, the full study of extraterrestrial objects, soil can help us to compare the differences between the earth and extraterrestrial objects faster, we can find out whether there may be aliens in other celestial bodies, if we can find health, this will have a greater role in promoting the future development of our human beings and the development of civilization.
