Military Technology

"Of course, this process is not required under normal circumstances. Relying on the communication system on the Mars exploration rover, we can achieve direct contact with the earth.

This use of satellite relay connections is a backup solution. When the Mars exploration rover cannot directly contact the earth, it can use this method to communicate. "

“In addition to this Mars aircraft, our Mars exploration vehicle also carries a small multi-purpose exploration vehicle, just like our Wangshu-1 lunar exploration and patrol vehicle.

Compared with the size of some other Mars rovers, the size of this small multi-purpose rover is not small at all. It mainly has two connection methods, one is wireless connection and the other is wired connection. Wireless connection can make its remote control distance reach about 500 meters. Of course, it must be in an open area without obstruction. If it is in some mountainous areas, this distance may be reduced.

The limited connection distance is two hundred meters, using cable connection, which is used to explore some narrow areas where wireless signals cannot be transmitted, such as caves, canyons, cracks, etc.

Because often these areas can store more valuable information about Mars. For example, on the moon, we use this small exploration vehicle to penetrate into the fold canyons on the lunar surface to obtain solid ice and liquid water.

We hope to use this small multi-purpose rover to go deep into these caves, canyons, and cracks on Mars to explore more location information on Mars, especially information about the existence of life.

If there is life on Mars, then these opponents are the most suitable for them to survive. "

At this point, Zhou Xiangming stopped, glanced at Wu Hao and Zhang Jun, and then continued: "In addition, this small multi-purpose exploration vehicle also has certain operation and rescue capabilities.

When the Mars Exploration Rover gets stuck, it can rely on its own power to drag the Mars Exploration Rover out.

At the same time, when the Mars exploration rover fails and the smart robotic arm mounted on it loses its function, or cannot work, this small multi-purpose rover can use the small smart robotic arm mounted on it to assist. repairs to help the Mars Exploration Rover return to normal.

After all, the situation on Mars is too complicated and the distance is so far away, and the task this Mars exploration rover has to perform is very difficult. Therefore, we must take relevant crisis response measures so that any problem encountered by this Mars exploration rover can be solved promptly and properly. "

After seeing Wu Hao nod, Zhou Xiangming continued: "In addition, our Mars exploration rover carries two multi-functional intelligent robotic arms for related scientific research work.

Such as picking up rocks, soil, and other objects from the surface of Mars. For another example, these two multi-functional intelligent robotic arms can be used to perform maintenance on its own car body and on-board equipment, such as cleaning solar panels and dust on the surfaces of other equipment and instruments so that they will not be affected.

We have also equipped this Mars exploration rover with a geological drilling system, which can drill two to three meters underground to extract deep soil samples from Mars.

For example, if there is water in the Martian soil, we can detect it through drilling.

For another example, if life once existed on Mars, there would definitely be organic matter in its soil. These surface soils may disappear due to various geological changes, wind erosion and other reasons, but they will definitely exist in the deep soil.

Through deep drilling, we can find evidence of life on ancient Mars.

In addition, we will also use this drilling system to select sites for the construction of our future Mars scientific research station.

It can be said that this Mars exploration rover did the work of the two Mars exploration rovers in the Wangshu series.

Is the reason for doing this to save money as much as possible? After all, it is not easy to go to Mars, so you have to be fully prepared. "

After hearing Zhou Xiangming's introduction, Wu Hao and Zhang Jun couldn't help but nodded, expressing their understanding of their design. It's true. Mars is too far away from the earth. It's really not easy to go there, so we must cherish it.

"With so many facilities and equipment stacked on the Mars rover, there is a lot of pressure on the Mars rover. It must ensure sufficient safety and reliability. You cannot lose sight of one thing and lose the watermelon. If there is a problem with the Mars rover, then these facilities and equipment What's the use of having more." Wu Hao reminded.

That's what you said. Yu Chengwu continued: "So the early testing work is particularly important. We will only allow it to launch after we ensure that the Mars exploration rover and the scientific research and detection equipment it carries are safe and reliable enough.

If we fail to meet our rigid requirements, then we would rather delay it for another two years and wait for the next window. "

What is this above? It's so big. Zhang Jun, who had been sizing up the Mars exploration rover, asked at this time.

This is the on-board mobile laboratory carried by our Mars exploration rover. Yu Chengwu replied with a smile: "Compared with the mobile laboratory carried on our Wangshu series of exploration rovers, the mobile laboratory on this Mars rover is more advanced.

First of all, the volume is much larger, so more functions are integrated. For example, this time, we equipped this mobile laboratory with a high-definition electron microscope so that we can observe the composition of the lunar soil more clearly. Another example: Microscope electrochemistry and conductivity analyzer, heat and released gas analyzer, interference imaging spectrometer, etc.

Putting so many scientific research equipment together will, to be honest, be a very stringent test for our entire engineering materials science, microelectronics integrated circuits, etc.

In particular, the environment on Mars is harsh and complex. It is also a huge problem to allow these scientific research instruments to maintain normal operation in such a harsh environment on Mars without affecting their performance. "

"How does this rover land? Does it still rely on sky crane technology?" Wu Hao asked.

Mars is different from the moon. Mars has an atmosphere, so its landing process is hugely different from that of the moon. In addition, Mars is too far away from the earth and human intervention is limited, so landing is more difficult.

Yes, after all, we have successful experience before us, so we will no longer look for other ways. This is also the greatest savings in resources.

In addition to the sky crane, because Mars has an atmosphere, we also prepared a parachute for it. Like Laomi's Mars probes, we also used a parachute and a sky crane to land. This method is more technically mature, more efficient, and relatively cheaper, so it is currently the best choice.
