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 more than 1,400 kilometers from our Zhihai Lunar Surface Scientific Research Station to the core of the golden meteorite. This distance is not to mention on the moon, it is on the earth. It's also a very long distance up.
What is the concept of this? It is almost the straight-line distance from Anxi to Shenzhen. The whole journey is driven on the highway. According to the average speed of 100 kilometers per hour, it takes almost fourteen hours.
And this is on the moon, and it is still in the original terrain environment of the moon, and it is all off-road, so you can imagine how difficult it is.
Therefore, before the start of this golden meteorite planet transfer mission, we need to conduct a comprehensive detection and analysis of the terrain environment between the Zhihai Lunar Surface Scientific Research Station and the area where the golden meteorite core is located, and then find out a few roads with the best conditions and safe driving. , the shortest distance road.
And it’s not just one, there must be several roads. To ensure that during actual driving, if you encounter some accidents that make the actual terrain road impassable, you will have to take a detour.
You know, this time not only are these detector robots and engineering transport vehicles traveling, they also have to carry a gold meteorite core weighing more than one ton, so they must be extra careful in planning the route and form. "
"Isn't it the route of the Yushu-1 inspection rover before? Why not follow the original route?" Zhang Jun asked.
Yu Chengwu smiled bitterly and shook his head: "The Wangshu-1 patrol probe was carried out along the exploration route, so it actually made a big circle. This journey took more than two lunar days, that is, It took more than two months to complete the journey, and the total mileage reached more than 2,000 kilometers. We can't spend more than two months on this task along such a road. It would be too time-consuming.
Therefore, we must re-plan a feasible, safe and shortest road to meet the needs of this transportation task. "
Seeing Zhang Jun nodded knowingly, Yu Chengwu breathed a sigh of relief, and then continued: "Based on the previous normal driving speed of the Wangshu-1 patrol rover on the lunar surface, it can travel approximately in one hour. Thirty to forty hours. If it uses solar panels to charge every day, it can only cover about 400 kilometers a day.
Calculated based on 1,400 kilometers, it would take four to five days to arrive at this speed. Even if we arrive at the scene, it will take a long time to clean out the golden meteorite star core that is half embedded in the lunar rock. A conservative estimate is that it will take at least three or four days. This is even if everything goes well. The premise. If there are some accidents or problems that may occur during the journey, then the time may be deduced backwards. It is not known how long the delay will be, and it may even cause the entire mission to fail.
Even if everything goes well and we take out the golden meteorite core, we still have to hit it hard into the engineering transport vehicle, and then slowly transport it to the Zhihai Lunar Surface Scientific Research Station.
Although the path has been discovered when you come here, it may not be applicable when you return. Mainly because it carries such a golden meteorite core that weighs a ton, so the choice of road is relatively strict.
Also because of the increase in carrying weight, the traveling speed of the entire fleet has been greatly reduced. It can intelligently travel about half the distance every day, which is about two hundred kilometers. In this case, just the return transportation may take a week.
The entire mission takes about fourteen days, which is exactly one lunar day. If it is delayed until the lunar night, then these exploration vehicles, robots, and engineering transport vehicles that rely on solar panels to generate electricity may go into sleep due to exhaustion of power and lower temperatures. Only when the next lunar day arrives can they be put back together. Wake up, recharge and start again.
And this is assuming everything goes well. Who knows whether these rover robots and engineering transport vehicles can withstand this lunar night.
So for us, this fourteen-day mission cycle is actually very tight. We must complete the mission before the lunar night arrives. "
Only in this way can we transport this golden meteorite star core to the Zhihai Lunar Surface Scientific Research Station, and only in this way can we hang it on the lunar landing and return experimental spacecraft launched in the autumn, and let it send this The golden meteorite core returns to Earth.
This transfer process is also very difficult, because the core of this gold meteorite is very heavy. It is the last planet and object brought back to the earth from the moon and the universe in the history of mankind.
Therefore, the entire transportation work is actually very complicated, involving many technologies, and the work is very cumbersome. For example, how to safely land this one-ton gold meteorite core from space to the earth, instead of becoming a bright meteor that burns up in space, or it becomes an asteroid that hits the earth and bombards a meteorite Pit, this is not a problem that can be solved by installing a few parachutes on it. There are too many factors that need to be considered during the process.
For example, the friction and high temperature on the surface of the star core when quickly passing through the atmosphere are also a very troublesome problem.
