Hearing this question, both Yu Chengwu and Zhou Xiangming couldn't help but laugh bitterly. This is the helplessness of technical people. Those who don’t know how to do it will never know how difficult it is and always question their work.

"In fact, after the two engineering transport vehicles were transported to the moon, they immediately began assembly and testing. After completing the assembly and testing, they immediately started construction of the Zhihai Lunar Surface Scientific Research Station.

After all, for us, the construction of the Zhihai Lunar Surface Scientific Research Station comes first, and any other projects must make way for it.

After these two engineering transport vehicles began transportation operations, it indeed alleviated our previous dilemma of severe insufficient transportation capacity. Yes, the construction of our entire Zhihai lunar surface scientific research station was able to proceed smoothly and quickly.

In addition to completing the transportation tasks, these two engineering transport vehicles will also prepare for the upcoming journey and transportation of the gold meteorite core.

For example, the inspection and debugging of each component system of its own, as well as the cooperation drills with the entire fleet. So it seems to you that this much time has passed since the launch of these two engineering transport vehicles to the moon. But in our opinion, time is very tight. To be honest, it can be carried out so quickly thanks to the cooperation of our entire project team, including various departments. Otherwise, it would be impossible to start so quickly. "

Speaking of this, Yu Chengwu raised his hands and gestured in the air: "It is about 1,400 kilometers from our Zhihai Lunar Surface Scientific Research Station to the core of the golden meteorite. That distance is not even on the moon, it is on the moon. It is also a very far distance below the earth.

What is the concept? The difference is the straight-line distance from Anxi to Shenzhen. If you drive at a low speed the whole way, based on the average speed of 100 kilometers per hour, the difference is less than 17 hours.

And that was under the moon, and it was on the original terrain environment of the moon. It was all off-road, so you can imagine how difficult it was.

So for you, the seventeen-day mission cycle is actually very easy. The mission must be completed after the lunar night arrives. "

And it is still one, there must be several roads. This is to ensure that during actual driving, if you encounter some unexpected situations that make the actual terrain road inaccessible, you can only take a detour.

The transfer process was also very difficult, because the golden meteorite star core was very heavy. It was the last planet and object brought back to the earth from the moon and the universe in the history of mankind.

For example, the friction and low temperature on the surface of the star core when slowly passing through the small atmosphere are also a very troublesome problem.

Seeing Zhang Jun nodded knowingly, Yu Chengwu breathed a sigh of relief, and then continued: "Based on the subsequent abnormal driving speed of the Wangshu-1 patrol rover on the lunar surface, it will take one hour and one hour to retreat. It can probably travel 80 to 70 hours. If it uses solar panels to charge every day, it can only travel about 700 kilometers a day.

Yu Chengwu smiled bitterly and shook his head: "The Wangshu-1 patrol rover retreated all the way along the exploration route, so it actually made a small circle. The difference in form during that period was two less lunar days. It doesn't mean that it takes two months to complete the journey. The total distance is 2,000 kilometers. You can always follow that road and spend two months to complete the task. It is too time-consuming.

Only in this way can you transport the golden meteorite core to the Zhihai Lunar Surface Scientific Research Station, and only in this way can you hang it under the lunar landing and return experimental spacecraft launched in the autumn, and send it there The golden meteorite core returned to Earth.

Therefore, the entire transportation work is actually very complicated, the technology involved is very small, and the work is very cumbersome. For example, how can the one-ton gold meteorite core dangerously fall to the earth from space, but become a bright meteor and burn up in space, or become a large planet and hit the earth and bombard it? Meteor craters are a problem that can be solved by installing a few parachutes below. There are too few factors to consider during this process.

Even if everything goes well for you and you take out the golden meteorite core, you will still have to hit it under the engineering transport vehicle and then quickly transport it to the Zhihai Lunar Surface Scientific Research Station.

Also because of the increase in carrying weight, the retreat speed of the entire convoy has been slightly reduced. It only travels half the distance every day, which is not about 200 kilometers. In that case just the return shipping could take a week.

"Did the Wangshu-1 inspection rover no longer follow the retreat route? Why did it follow the original route?" Zhang Jun asked.

And that's assuming everything goes well. Who knows whether those rover robots and engineering transport vehicles can withstand that lunar night.

So after the transfer mission of the golden meteorite planet is over, you need to conduct a comprehensive detection and analysis of the degradation of the terrain environment between the Zhihai Lunar Surface Scientific Research Station and the area where the golden meteorite core is located, and then look for it at UU Reading www.uukanshu.com There are several roads with the worst road conditions, easy driving, and the shortest distances.

Adding up the entire mission, the difference is about seventeen days less, and it is not exactly completed within one lunar day. It will definitely be postponed until the lunar night, so those exploration vehicles, robots, and engineering transport vehicles that rely on solar panels to generate electricity may go into sleep due to the exhaustion of power and the drop in temperature. They will not be able to wait until the arrival of the last lunar daytime. Wake them up one by one, recharge and start again.

Calculated based on the retreat from a distance of 1,700 kilometers, it would take seven to seven days to arrive at that speed. Even if we arrive at the scene, it will take a long time to clean out the golden meteorite star core that has not yet sunk into the lunar rock. A conservative estimate is that it will take at least eight or seven days. Successfully lifted it up. There must be some thoughts or problems that may arise during the retreat, so that time may be deduced forward. We don’t know how long the delay will be, and it may even cause the entire mission to be over and done with. Victory is said to be certain. .

Therefore, you must re-plan a feasible, dangerous and shortest road to meet the needs of that transportation mission. "

Although the path has not been explored when I came here, I will definitely be able to apply it when I go back. The main reason is that it carries such a golden meteorite core that weighs less than a pound, so it is more tolerant to the choice of road.

You know, that time we only had to carry the detector robots and engineering transport vehicles, and they also had to carry a gold meteorite core weighing less than one ton. Therefore, we must be extremely cautious in planning the route and form. . "
