After listening to Zhou Xiangming's introduction, Wu Hao and Zhang Jun couldn't help but feel surprised. Indeed, there are too many incomprehensible and irrational things in this world, which are constantly breaking human cognition.

In fact, this is also a process of development. In the past, many things that we thought were impossible, unreasonable, and even incomprehensible have come true.

A few decades ago, who would have thought that the Internet would be so developed in the world today. Everyone has a computer and mobile phone, and everyone’s mobile phone can connect to the Internet, play games, and watch movies and TV series. This is something that people a few decades ago could not understand. Things that feel impossible.

A hundred years ago, who would have thought that a train could reach a speed of nearly 400 kilometers per hour, who would have thought that a plane could carry three to four hundred people, who would have thought that an artificial heart could actually replace the heart, and that intelligent bionic electronic prosthetics could actually replace arms. People can live in space for months or even years, etc. These are all impossible things.

So with the advancement of our science and the in-depth and comprehensive observation, those unreasonable and impossible things begin to become reasonable.

Isn’t it true that human beings have continued to progress and develop to today through so many impossible, unreasonable, and even incomprehensible historical processes? Who could have imagined that hundreds of thousands or millions of young apes, who could only use stones and sticks, would develop to the point where they are today? Is this reasonable?

Therefore, as to whether there is life on Mars, no one can be sure until there is no conclusive evidence. No one dares to conclude that there must be living things on Mars or there must be no living things. This is unscientific.

So, do you believe there are living things on Mars? Wu Hao asked with a smile.

Hearing Wu Hao's question, Yu Chengwu smiled and shook his head: "Currently, no one has any evidence to prove that there are living things on Mars, and there is also no evidence to prove that there must be no living things on Mars.

However, after combining the opinions of some biologists, including geologists and other scientists and professors, we believe that there may be some organisms on Mars that can adapt to the surface of Mars, or to the Martian stratigraphic caves or underground rivers.

Of course, this is just a speculation. Whether it is specific or not requires evidence.

Therefore, a major mission of our Mars exploration rover is to explore whether there are biological survivals on the surface of Mars, including some rock formation gaps, valleys, seasonal liquid water, etc.

And we may also release some small detectors to detect deep into caves and look for evidence of biological existence.

In addition, we will also look for evidence of the existence of ancient organisms on Mars, if Mars gave birth to life in ancient times. "

Speaking of this, Yu Chengwu spread his hands and said with a smile: "Of course, all this is based on the fact that Mars gave birth to life in ancient times. If life had not been given birth to in ancient times, then it would be very difficult to give birth to life in the current environment of Mars, and the probability is very high. Low.

In other words, overturning the previous assumptions and speculations, Mars has been like this from ancient times to the present. In this case, there may be no conditions for the existence of life. "

Zhou Xiangming next to him nodded and said: "This is also an attempt on our part. After all, this is a hot topic in Mars exploration. We also hope to attract social support and sponsorship through projects in this area. There are already many scientific research projects. Institutions and scientific research funds are interested in this project and are having more in-depth communication and exchanges with us on cooperation."

“In addition to searching for life, this Mars exploration rover will also undertake an important task, which is to search for and detect mineral deposits on Mars just like on the moon.

This will be of great help to our future exploration and use of Mars, Mars scientific research, Mars settlement, and even Mars immigration. It can be said to be a prerequisite.

Therefore, this Mars exploration rover will, like our Wangshu-1 lunar exploration rover, collect soil and rock samples from different areas on Mars, and then send them back to Earth in the future, or conduct research on the surface of Mars.

In addition, this Mars exploration rover will be equipped with the most advanced analytical laboratory to analyze the collected soil and rock samples to obtain more detailed data. "

After listening to Zhou Xiangming's introduction, Wu Hao immediately said: "The environment on Mars is completely different from that on the moon. You must determine whether the Mars exploration rover using the Wangshu lunar exploration rover technology platform can adapt to the complex environment on Mars. Pay special attention, as this can determine the success or failure of the project.”

Your direction has always been the focus of our research. Yu Chengwu replied seriously.

“Although this Mars exploration rover is developed based on the technical platform of the Wangshu lunar exploration rover, it is actually very different.

For example, the weight and volume of this Mars exploration rover are several times that of Wang Shuhao’s Mars exploration rover. In addition, for the special environment on Mars, we have completely upgraded the entire vehicle body.

For example, new wheels have been upgraded to adapt to the Martian surface environment. This new tire made of polymer materials can adapt to various terrain environments on Mars, such as deserts, gravel beaches, mountains, snow, even muddy areas seasonally flooded by surface water, and wading areas. wait.

Unlike the metal wheels of traditional Mars exploration rovers, they may gradually become damaged and rotten as the distance and time traveled increase. For example, the wheels of Laomi's Curiosity Mars rover were seriously damaged.

Our polymer material wheels have very high strength and toughness, and have a certain degree of elasticity. They can also withstand high and low temperatures, and even the erosion of water and sandstorms. They are suitable for long-term off-road driving and the wear and tear of sand and gravel on the tires. This results in a longer service life.

In addition, we have also upgraded and improved the suspension system of this vehicle so that it can not only adapt to more complex terrain environments, but also increase or decrease the ground clearance of the Mars Exploration Rover according to the road it is traveling on, improving Its ground clearance in complex terrain environments.

At the same time, it is also very waterproof when encountering wading roads, so it can be driven in water.

Another example is that in order to adapt to the frequent sandstorms on Mars, we have installed special dust-proof technology for the solar panels we carry.

The first step is to spray new materials on the solar panels to reduce the retention and accumulation of sand on them. Just gently vibrate the solar panels, or the vibrations generated by the Mars rover while driving, can make the dust accumulated on the solar panels fall off, thus playing a self-cleaning role. "
