Six days later, the Lunar Cargo Transfer-3 spacecraft assembly is about to 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 the landing procedure.

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 landers 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 throughout the world, arousing people's cheers and joy. However, some people were disappointed, with jealousy and anger palpable.

However, these disturbances have nothing to do with the project itself, because what matters now is the unfolding of the follow-up work. The first and most important job 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 supplies can withstand the temperature difference between day and night on the moon, but some equipment cannot. Therefore, these equipment and parts are temporarily stored in the lander's cargo bay to provide necessary protection.

The engineering transport vehicle is one of the key equipment for unloading, although the appearance of the vehicle is not yet visible. 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 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 a multi-purpose engineering robot to the Zhihai Lunar Surface Scientific Research Station a few hundred meters away for assembly.

This multi-purpose engineering robot can also be equipped with a small truck body to undertake some transportation work. In fact, these two multi-purpose engineering robots are responsible for the lunar soil transportation required for the construction of the Zhihai lunar scientific research station. It's just that they are not professional transport vehicles after all, so they can only carry relatively few goods.

This is 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 gold meteorite core is relatively high, it is not so high that two engineering transport vehicles were specially transported.

Why not assemble it on site but transfer it to the Zhihai Lunar Surface Scientific Exploration 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 soil 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 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 account how to assemble it on the moon. And during the disassembly and transportation process, it is disassembled into more complete parts as much as possible. Therefore, on the moon, you only need to assemble these parts in the corresponding order like building blocks.

Once the assembly is complete, 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 power supply systems such as solar panels or isotope thermoelectric batteries, so it requires an external power supply 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 super solid-state batteries are already very safe, considering that severe vibrations that may occur during spacecraft launch and landing can cause the batteries to short-circuit and cause fires. Therefore, 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. Like the 100-degree battery equipped in this engineering transport truck, 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, problems may occur if you are not careful.

The environment on the moon is very harsh, and rashly using too radical a plan may 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 and out of reach. Once a certain system or component has a problem, it will cause the entire detector to fail. There are too many examples of this.
