Of course, because this satellite has many functions and many scientific research and verification projects to be carried out, the weight of this satellite is naturally quite large. The weight of this satellite reaches as much as 12 tons. At present, except for the similarly No. 5 rocket that their Tiangong Technology has manufactured, there is no rocket that can send this satellite into the Earth-Moon Transfer Orbit. Even the current Tiangong-4 rocket cannot send such a heavy satellite into the Earth-Moon Transfer Orbit.

Although the total weight of the Tiangong-4 rocket has reached about 800 tons, which is almost the same as the official largest rocket, because Tiangong-4 rocket of Tiangong Technology is a recyclable rocket, its carrying capacity is much lower than that of the same type of rocket, so it cannot undertake this launch mission at all.

Fortunately, their Tiangong-5 rocket has been manufactured now and can also send this satellite into the Earth-Moon transfer orbit.

Of course, like the Tiangong-4 rocket, the Tiangong-5 rocket is also a recyclable rocket, but unlike the previous recyclable rockets, the last stage rocket of the Tiangong-5 rocket does not use the traditional liquid hydrogen and liquid oxygen rocket engine, but uses the latest Hundred-Kanniu aircraft atomic engine developed by Tiangong Technology.

After all, atomic engines do not require liquid oxygen for combustion, as long as there is liquid fuel, which makes Tiangong Technology very optimistic about this engine and also very optimistic about the future of this engine.

In fact, this atomic engine technology is also the technology purchased by Wang Bin from the technology mall. Its technical prototype is Kanxing's "subner nerve" atomic rocket engine.

The prototype of this engine, the "subner nerve" atomic rocket engine, has only 60,000 N. After improvement and development by the R&D personnel of Tiangong Technology, this 100,000 N atomic rocket engine was developed.

Like the previous prototype "subner nerve" atomic rocket engine, the weight of this atomic engine is much heavier than that of ordinary liquid hydrogen and liquid oxygen engines. Not to mention anything else, just talk about the atomic rocket engine developed by Tiangong Technology now has a thrust of only about 10,000 knots, which is 10 tons, but its own weight reaches nearly five tons, which is definitely several times that of other rocket engines with the same thrust.

However, the pulse is much larger than a liquid hydrogen and liquid oxygen engine, and is far from comparable to a liquid hydrogen and liquid oxygen engine. Therefore, this can allow this stage of rocket to store more fuel, allow the rocket to send heavier objects into higher orbits, and also recycle this stage of rocket.

This stage of rocket must have enough fuel to return after sending the satellite into the Earth-Moon transfer orbit. However, if you use an ordinary rocket engine, that is, liquid hydrogen and liquid oxygen rocket engines, you must carry more fuel. After all, you have to send the spacecraft into the Earth-Moon transfer orbit, and the speed must reach at least 11 kilometers per second.

However, when the rocket is sent to the rocket and it is necessary to return, the rocket must reduce its speed again. At this time, the rocket's engine needs to be completed. If a liquid hydrogen and liquid oxygen engine is used, it must carry a large amount of fuel. In this way, the rocket's carrying capacity will be greatly reduced, and it can even reach a carrying capacity of less than 10 tons. This is definitely not the structure that Tiangong Technology wants to see.

If this is true, then Wang Bin and the others might as well not recycle the last stage Rockets!

Fortunately, with the atomic rocket engine, since liquid oxygen is not needed as an oxidant, although the engine weighs heavily, the total weight of the last stage can be reduced to a level that Tiangong Technology can bear.

It can be said that the Tiangong-5 rocket uses a lot of new technologies from Tiangong Technology. At the same time, the satellite launched this time is a gathering of many key advanced technologies in Tiangong Technology.

So it took Wang Bin and his team more than a month to design and manufacture the satellite. At the same time, the Tiangong-5 rocket had been manufactured long ago, but since the satellite had not been manufactured yet, the No. 5 rocket was not launched during this period.

However, with the completion of satellite manufacturing, the launch of the rocket has also been put on the agenda.

Of course, Wang Bin and his team have also reported to their superiors about Tiangong Technology's upcoming launch of lunar exploration communication satellites, and have also obtained the consent of their superiors.

And in the superior department, when submitting the application report submitted by Tiangong Technology, it also attaches great importance to this. At the same time, it also attaches great importance to the latest technologies such as Tiangong Technology. After all, all the technologies used on this rocket satellite are the world's top technologies.

Therefore, in order to improve national self-confidence, the official also carried out large-scale publicity on this. After all, the lunar exploration satellite launched this time was not launched by official space agencies, but by domestic private space companies.

The most important thing is that the rockets and satellites launched this time were completely developed by Tiangong Technology itself, and were not provided by the official technology and supported.

And in the publicity, the official also clearly stated that this satellite used the latest communication methods developed by Tiangong Technology and verified its technical feasibility at ultra-long distances.

Therefore, when the news was officially announced, it caused a huge response throughout the country and even around the world.

After all, the one who launched the lunar satellite this time is a private space company in China! It is not an official space company.

You should know that even the most advanced private space company in the world before, x space company, has many plans, including the moon plan, etc.

But in fact, in addition to launching their company's Starlink program and launching some Earth satellites, they did not launch plans for lunar exploration and moon landing. At this time, they were vigorously stepping up their company's interstellar spacecraft test flight and test improvement projects.

However, now, before even the spacecraft was built, someone wanted to start the moon plan first, so how could they be affected?

So as soon as Tiangong Technology is about to launch a lunar satellite, it attracted great attention from X Company once it was officially disclosed. The person in charge immediately announced that their company will also launch lunar exploration satellites in the near future and collect the lunar landforms to lay the foundation for their company's upcoming lunar plan.

At the same time, the official publicity on the Internet has also caused heated discussion.
