Chapter 2972: As steady as an old dogs moon landing!
Six days later, the Lunar Cargo Transfer-3 spacecraft assembly will begin landing on the moon.
In fact, as early as two days ago, the Lunar Cargo Transfer-3 spacecraft had arrived at the moon and successfully completed near-lunar braking and orbiting the moon.
After two days of flying around the moon, the spacecraft has changed from an elliptical orbit around the moon to a nearly circular orbit around the moon, and separated ten hours ago. After separation, the landing module carried about ten tons of cargo and started landing.
program.
The entire process was broadcast live to the world. Wu Hao and Zhang Jun of Haoyu Technology also watched the entire landing process at the Xinyuehu Space Command and Control Center.
Compared with the previous two landings, this time it was very smooth, without any accidents, as steady as an old dog!
After a thrilling fifteen-minute landing, the lander of the Lunar Cargo Transfer-3 spacecraft steadily placed the cargo on the landing site of the Lunar Zhihai Lunar Surface Scientific Research Station.
Next to the lander are the lander of the retired Lunar Cargo Transfer 1 spacecraft and the lander of the Lunar Cargo Transfer 2 spacecraft.
The lander of spacecraft No. 1 has been mostly dismantled and used for the construction of scientific research stations; while the lander of spacecraft No. 2 is still in working condition because it carries a large number of scientific instruments.
However, they will also face the fate of being dismantled, because many parts and resources cannot be fully utilized there.
The news that the Lunar Cargo Transfer-3 spacecraft successfully landed on the moon spread all over the world, arousing people's cheers and joy. However, some people were disappointed, jealous and angry.
However, these disturbances have nothing to do with the project itself, because what is important now is the unfolding of the follow-up work. The first and most important task is to unload the cargo from the spacecraft.
Of course, you can't unload them all at once, you have to do it selectively according to the plan. Most of the materials can withstand the influence of the temperature difference between day and night on the moon, but some equipment cannot withstand it. Therefore, these equipment and parts are temporarily stored on the landing
in the cargo compartment of the vessel to provide necessary protection.
The engineering transport vehicle is one of the key equipment for unloading, although the appearance of the vehicle cannot be seen yet. In order to facilitate transportation, the two engineering transport vehicles have been disassembled into hundreds of parts and placed on the lander.
The larger components are mounted on racks on the outside of the spacecraft lander to maximize the use of space and resources.
With the help of intelligent control robots, the body frame of the engineering transport vehicle was unloaded from the lander. Next, other components of the first engineering transport vehicle will be transported by the multi-purpose engineering robot to Zhihaiyue, a few hundred meters away.
It will be assembled at the scientific research station.
This multi-purpose engineering robot can also be equipped with a small truck body to undertake some transportation work. In fact, the lunar soil transportation work required for the construction of the Zhihai Lunar Surface Scientific Research Station is undertaken by these two multi-purpose engineering robots.
. It’s just that they are not professional transport vehicles after all, so they can only carry relatively few goods.
This is also the reason why it takes so much effort to transport two professional engineering transport vehicles to the moon, not just to transport the golden meteorite core. Although the value of this golden meteorite core is relatively high, it is not as high.
To the point where two engineering transport trucks were specially brought in.
Why not complete the assembly on site but transfer it to the Zhihai Lunar Surface Scientific Research Station for assembly? This is mainly because the entire assembly process requires human control, and the communication at the research station is more convenient, making it easier for Earth control and command.
In addition, compared to the landing site, the environment at the Zhihai Lunar Surface Scientific Research Station is relatively better.
The landing site is filled with relatively soft lunar sand, while the research station uses floor tiles printed from lunar soil to lay an engineering operating platform. The unpacking of many materials and the assembly and maintenance of equipment are all done on the
It's done here and the facilities are relatively complete.
As for transporting an engineering transport vehicle back first, the purpose is to quickly assemble it first and then participate in the process of transporting other materials. In this way, the entire transportation speed will be faster and not too much money will be spent on the material transfer process.
time.
The assembly of the entire engineering transport vehicle is actually relatively simple, because the design took into consideration how to assemble it on the moon. And during the disassembly and transportation process, it was disassembled into more complete parts as much as possible, so on the moon, only
Just assemble these parts in the corresponding order like building blocks.
After the assembly is completed, you can charge this engineering transport vehicle. This engineering transport vehicle is powered by batteries. In order to facilitate the transportation of goods, it will not carry any solar panels, isotope thermoelectric batteries and other power replenishment systems installed on it.
, so an external power supply is required for charging.
If it cannot be recharged in time, it will be a one-time device. However, there is a dedicated solar power station for power supply at the Zhihai Lunar Surface Scientific Research Station, which can fully meet the needs of daily use.
Therefore, for the convenience of transportation and for the safety during transportation, the super solid-state batteries used by these two engineering transport vehicles do not carry any power. Although the super solid-state batteries are already very safe, they need to be considered during the launch of the spacecraft.
And the severe vibrations that may occur during navigation and landing can cause the battery to short-circuit and cause a fire. Therefore, the batteries transported in the cargo hold are usually uncharged. In this way, even if a short-circuit occurs, there will be no problem.
In order to improve the work efficiency of the entire engineering transport vehicle and save time, these two engineering transport vehicles, no, it should be said that the three robots they sent to the moon in the early stage and these two engineering transport vehicles this time all use fast charging technology.
, so charging is very fast. For example, the battery equipped in this engineering transport vehicle with a temperature of about 100 degrees, the entire charging time only takes about half an hour to complete.
This charging speed is nothing on earth, because Wu Hao’s ultra-high-voltage wireless remote charging technology only takes less than ten minutes to fully charge a 100-degree battery, and half an hour can almost fully charge a large battery of three to four hundred-degree batteries.
.
But this is on the moon 380,000 kilometers away, so for the sake of safety, we chose a very stable and reliable charging solution. Because high-voltage charging is actually very dangerous, and problems may occur if you are not careful.
The environment on the moon is very harsh, and rashly using too radical solutions is likely to cause many problems. Therefore, the technology on many detectors is not actually the most advanced technology, but the most reliable technology. After all, they are too far apart.
It is beyond our reach. Once there is a problem with a certain system or a certain component, it will cause the entire detector to fail. There are too many examples of this.
