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 these 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 started transportation operations, it indeed alleviated our previous dilemma of severe insufficient transportation capacity. Therefore, 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, and the coordination drills with the entire fleet. So in your opinion, it has been so long since the launch of these two engineering transport vehicles to the moon. But in our opinion, time
It is very urgent. To be honest, it can be carried out so quickly thanks to the cooperation of our entire project team, including all departments, otherwise it would not be possible 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 distance is the straight-line distance from Anxi to Shenzhen. If you drive at a low speed the whole distance, based on the average speed of 100 kilometers per hour, the distance is 17 hours.
And that was under the moon, and it was on the original terrain environment of the moon, and 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 road, and several roads must be provided. To ensure that during actual driving, if some unexpected conditions are encountered and the actual terrain road is passable, the only way is to 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 kilometers. 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 inspection rover retreated all the way along the exploration route, so it actually made a small circle. The difference in form during that stretch was two less lunar days.
It doesn't mean that it takes two months to complete the journey. The total distance is two thousand kilometers. You can always follow that road and spend two months to complete the task. It would be too time-consuming.
Only in this way can you transport the golden meteorite star 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 let it send it
The golden meteorite core returned to Earth.
Therefore, the entire transportation work is actually very complicated, involving very little technology, and the work is very cumbersome. For example, how to dangerously land the one-ton gold meteorite star core from space to the earth, but it becomes a
A bright meteor burns up in space, or it becomes a large planet and hits the earth and creates a crater. That is a problem that can be solved by installing a few parachutes below. There are too few factors to consider during the process.
not enough.
Even if everything goes well for you and you take out the golden meteorite core, you still have to hit it under the engineering transport vehicle with great effort, and then quickly transport it to the Zhihai Lunar Surface Scientific Research Station.
Because of the increase in carrying weight, the entire fleet's retreat speed has been slightly reduced. It can travel roughly half the distance every day, which is not about 200 kilometers away. In that case, just the return transportation may 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 terrain and environmental degradation between the Zhihai Lunar Surface Scientific Research Station and the area where the golden meteorite core is located, and then find out the roads with the worst conditions and drive on them.
Huiran, the shortest road.
Adding up the entire mission, the difference is about seventeen days, which is not exactly within a lunar day. It will definitely be delayed until the lunar night. Such exploration vehicles, robots, and engineering transport vehicles that rely on solar panels to generate electricity
They may go into hibernation because the battery is exhausted and the temperature drops. It is not until the day of the last lunar day that they can be awakened one by one, recharged 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, we want to remove the golden meteorite core star that has not yet sunk half into the lunar rock.
It will take a long time to clean up nuclear mining. A conservative estimate is that it will take at least eight or seven days, and that will be added after everything goes smoothly. There must be some worries or problems that may arise during the retreat, so that time will be enough
It may be deduced forward, and we don't know how long it will be delayed, or it may even lead to the entire mission being over and over, and victory is certain.
Therefore, you must re-plan a feasible, dangerous and shortest road to meet the needs of that transportation mission."
Although the road has not been discovered when I came here, it will definitely be applicable when I go back. The main reason is that it carries such a golden meteorite core that weighs less than a pound, so I am more tolerant of the choice of road.
You know, that time it was not just those detector robots and engineering transport vehicles that were traveling, but they also had to carry a gold meteorite core weighing less than one ton, so it was important to be extremely cautious in planning the route and form.
