"Thank you Mr. Wu for your support and understanding."

Zhou Xiangming showed a grateful expression. To have such a considerate boss is definitely a blessing in this life for those who are engaged in technology.

Wu Hao waved his hand, then signaled him to continue.

Seeing this, Zhou Xiangming nodded and continued: "In fact, there are still a series of problems in the recovery of rocket bodies at sea. There will be a series of troubles and problems.

In addition, the special high-salinity and high-humidity environment at sea will also bring a series of problems to the launch and recovery of the rocket body.

In terms of time, I won't go into details.

However, compared to the advantages or advantages brought by the transfer to the South China Sea landing site, this little disadvantage or disadvantage is insignificant.

First of all, the first one is the dimensional advantage brought by the low-latitude launch site, which means that we have more orbits and launch angle windows.

Secondly, low latitudes can rely on the centrifugal force brought by the earth's rotation to save rocket fuel and increase the rocket's capacity, which is impossible for high latitude launch sites.

Increased rocket capacity means we can send more and heavier loads into space. And the benefits it brings are much higher than the costs it brings.

Finally, it is about the rocket wreckage and even the recovery of the rocket body.

In the past, when we launched a one-off conventional rocket in the inland, we had to control the wreckage of the first and second stages of the rocket, as well as the fall area of ​​the fairing.

And contact the local people in these landing areas in advance, and do a good job in the evacuation and transfer of personnel, other livestock and property in the landing area.

This work is not only very troublesome, but also very restricted, and the related approval process is very strict. And this will also result in an additional cost.

If there is a deviation, it will also bring a series of problems and troubles.

But if you put it at the South China Sea launch site, you don’t have to worry about this problem, because whether the rocket launches to the east or south is the sea, so you don’t have to worry about the rocket wreckage falling down and hitting something.

Of course, even if it is placed on the sea, there is such a possibility. The wreckage of the rocket fell and hit a ship passing in the area.

However, this probability is too low, even lower than the odds of winning the lottery.

And under normal circumstances, before the rocket launch, the international maritime department and related areas will also be notified of the fall area of ​​the rocket wreckage, so that some ships passing through this area can avoid it in advance.

Next, let's talk about the recovery of the rocket body of the recoverable rocket. In the past, there were fixed landing sites in the interior. This also means that the landing and landing of the rocket body must be carried out on a fixed landing site, which greatly limits the launch trajectory of the rocket.

And this kind of fixed landing site requires constant adjustment of the rocket body, which will waste part of the fuel.

As for the mobile landing platform at sea, it can be arranged at the optimal target position we need, and it can be changed at any time according to the relevant launch needs, so as to find an optimal landing site position.

This is something that inland fixed landing sites cannot do, and the resulting benefits are also considerable.

Finally, in terms of policy, the South China Sea launch site is an international space port built by the aerospace authorities. Compared with other inland launch sites, it is more open.

This also means that we will enjoy more favorable policies here, as well as convenient conditions and a superior environment.

And we can also use this platform to absorb more international orders, which will also be an important move for us to enter the overseas market. "

clap clap clap...

Wu Hao took the lead in applauding, and then praised Zhou Xiangming while applauding: "That's a good speech,

It can be seen that you have worked hard in this area, which is worthy of recognition, and all of you should learn more from Xiang Ming. "

Speaking of this, Wu Hao took a special look at Yang Fan. As for Yang Fan, after noticing Wu Hao's gaze, he dodged immediately. He couldn't understand what Wu Hao meant.

Seeing Yang Fan's reaction, Wu Hao smiled, took a sip from his teacup, and said to Zhou Xiangming, "That's all about the rocket, let's talk about our smart lunar exploration rover." project.

It is almost a year away from the launch time we announced. I wonder if the whole launch plan will go ahead as planned. "

Zhou Xiangming nodded when he heard the words and said, "I am personally in charge of our smart lunar exploration vehicle project.

At present, the overall progress of this project is relatively smooth, which can basically guarantee that the launch plan will be carried out as scheduled. "

What is basically guaranteed to go on schedule? Wu Hao became a little displeased. He hated this kind of ambiguous answer the most, especially when it comes to work.

Faced with Wu Hao's displeased tone, Zhou Xiangming quickly explained: "This smart lunar rover project does have some technical problems that we haven't solved yet, and we are already adding manpower and working overtime to overcome them.

It's just that what we are doing now is a brand new project that has never had a precedent, without any reference, so all this needs to be explored by ourselves.

According to the design, this intelligent lunar exploration vehicle will be launched by the Jianmu-7 rocket and enter the Earth-Moon transfer orbit.

After entering the lunar orbit, the intelligent lunar exploration vehicle will choose an opportunity to land on the moon after decelerating. Unlike other lunar exploration projects, this time we will adopt a black technology from Lao Mi's Mars exploration project.

That is to use sky crane technology to hang our intelligent lunar exploration vehicle to land on the moon.

After the intelligent lunar exploration vehicle lands on the moon successfully, the suspension steel cable of the sky crane will be separated quickly, and then the sky crane will immediately fly away and fall.

Any mistakes or failures during this period will cause the entire project to fail.

For example, the sky crane hangs several steel cables of the intelligent lunar exploration vehicle. After the intelligent lunar exploration vehicle lands on the moon, if one of the several steel cables is not disconnected in time, then the sky crane will directly move the intelligent lunar exploration vehicle to the moon. The probe car was hoisted and fell, or even pulled and damaged.

Or, the sky crane can't disengage normally, so it hits the smart lunar rover directly.

For another example, if one of the thrust engines on the sky crane fails, it will also cause the entire landing mission to fail and the intelligent lunar exploration vehicle to crash.

Even, including the descent angle posture of the sky crane and the intelligent lunar exploration vehicle during landing, will directly determine the success or failure of this mission. "
