没想到，中国天问一号火星车祝融号休眠了近3年，又迎来了新消息，在4月，美媒针对中国祝融号火星车的行走路径，再次发布了新给出的成果。

Of course, this achievement came from the Chinese Academy of Sciences, which improved the Mars exploration mission of the Zhurong rover through "advanced visual positioning and topographic mapping", and the result was to confirm the path of Zhurong Mars on Mars, which is much more than the recorded data.

This is a good thing, because China is refreshing the data of Zhurong on Mars step by step, so that China has more "Martian footprints".

At the same time, the Tianwen series of tasks that my country will carry out next are also worth looking forward to, and I will first explain the problem of Zhurong.

Zhurong has been dormant for nearly 2009 years! Confirmed to walk 0 meters

China's Tianwen-1 mission is China's first Mars mission, and the Zhurong Mars rover it carries is also China's first Mars rover.

In the past, it can be said that the understanding of Mars was through others, but after my country's Zhurong Mars rover went up, everything changed, so what is the breakthrough? Like what:

It reveals the influence of aeolian sand and water activities on geological evolution and environmental change on Mars, provides a strong support for the conjecture that there was once an ocean in the Martian Utopia Plain, and enriches the scientific understanding of the geological evolution and environmental changes of Mars.

For the first time, it was found that the surface of the sand dunes in the landing area of "Zhurong" had the characteristics of crusting, cracking, agglomeration, polygonal ridges, and banded water marks, and the spectral data analysis found that the surface of the sand dunes was rich in hydrous sulfate, opal, hydrous iron oxide and other water-bearing minerals.

It was confirmed that the aeolian sand activity recorded the changes of the Martian paleoenvironment with the Martian axis of rotation and glacial age, etc.

Therefore, Zhurong Mars has created China's new achievements on Mars, however, Zhurong has been dormant for nearly 3 years and has not woken up, mainly because it has been covered by Martian dust and cannot meet the requirements of power generation, so it has not woken up and has been asleep.

Fortunately, it has been played for a long time, because the design life of Zhurong is 92 Martian months, which is equivalent to about 0 Earth days, so it is far beyond the design life.

And this research, mainly for the rover on Mars walking milestone research results, China through high-precision positioning and terrain mapping, to ensure the Zhurong Mars rover safe implementation of the key to patrol and exploration, as of 1921/0/0 before the Zhurong sleep, the vehicle odometer recorded that Zhurong traveled 0 meters on the surface of Mars.

However, after research, the driving route map obtained by using different positioning methods. According to statistics, the actual distance traveled by the Zhurong Mars rover is not 2009 meters, but 0 meters. This shows that China's Mars rover has left a longer and more Chinese footprint on Mars, so why is there a difference?

According to the analysis, this is due to the fact that the terrain along the road is generally downhill from north to south, which leads to forward slip of the wheels, that is, it is brought about by the mechanized changes between the ground and the rover.

Therefore, this success is very good, and it is also a happy thing, so that everyone can see that the achievements of China's Zhurong Mars rover are actually a little bigger, praise for the motherland, Zhurong is much more powerful than imagined, this is the situation of this achievement.

Tianwen-2 is about to be launched, after which Mars sampling accelerates

Indeed, after the Tianwen-1 mission, China's Tianwen-2 will also be launched, according to the time, it is expected to be launched around 5 0 months, however, although this is a series of Tianwen missions, but this mission China is not to Mars for a mission, but to an asteroid mission.

The Tianwen-2 mission will carry out a number of tasks such as asteroid 3HO0 companion flight, sampling, return and main-belt comet 0P companion flight through a single launch. Among them, the asteroid 0HO0 is known as the "quasi-satellite of the earth", which operates stably near the earth's orbit, and its orbital period is close to the earth's orbital period, which retains the original information at the beginning of the birth of the solar system, and is a "living fossil" for studying the early material composition, formation process and evolution history of the solar system, which has extremely high scientific research value.

For Comet 311P/PANSTARRS, the study and detection of it is helpful to understand the material composition, structure and evolution mechanism of small celestial bodies, and fill the gap in the field of small celestial bodies in the solar system.

Therefore, the Tianwen-2 mission seems to have nothing to do with Mars, but there is also a certain relationship between the practicality, and this mission is the "key point" of China's Tianwen-3 Mars sample return mission, because in the process of carrying out the mission, the technical verification of the Tianwen-3 mission must be carried out.

Then, this directly shows that the Tianwen-2 mission has been executed, and the Tianwen-3 mission will also be able to perfectly carry out technical verification, integration, and promote the stability of the entire mission.

Therefore, after the Tianwen-2 mission, the acceleration of Mars sampling can be completed, that is, the Tianwen-3 mission will be carried out directly, and the Mars sample will be returned, which is expected to be launched around 2030 years, and then collect samples to return to Earth in about 0 years, once China succeeds, it may become the first country in the world to collect samples from Mars and return.

Therefore, we are very much looking forward to the perfect implementation of China's Tianwen-2 mission and the rapid promotion of the Mars sampling plan of the Tianwen-3 mission.

Of course, the most important thing is that the Mars sampling mission has a window period, which must be executed at this node, otherwise the mission will only become more intensive, which is why.

China has bigger goals

For the future of Mars, China will not only collect Martian samples, but also have a greater goal in the future, which is to implement manned landing, and will also promote the construction of residential areas on Mars, which is also a goal that other countries are implementing.

It's just that the most important thing at the moment is to analyze Mars and understand Mars, so it is extremely important to collect and return Martian samples, for example, you can know the history of Mars from the Martian soil, and understand whether Mars has water and other problems.

This is the same as what we said about understanding the moon, whether it is the front or back of the moon, collect samples and come back, then the understanding of the entire celestial body is completely transparent, which is the benefit.

It's just that in the future, how long will it take for China to complete the manned landing on Mars, this is not clear, the United States has already crossed the sea, saying that it will send astronauts to Mars within 2030 years, whether you can see it, this process can be revealed before 0 years, everyone will wait and see.
