The Changqi Yaosan carrier rocket arrived in Wenchang, Hainan. What are the uses of launch vehicles?

Of course, launch vehicles have many benefits, and it is precisely because of their many uses that our country will vigorously develop. Launch vehicle is our core key technology. Only when it is well developed can our ability to explore the outside world be greatly improved. This is my personal opinion.

First of all, the launch vehicle can transport artificial earth satellites. We all know that artificial earth satellites are widely used. In our daily life, some TV channels communicate with the electronic equipment we use through artificial earth satellites. Then, if our launch vehicle continues to improve, it will be able to send more artificial earth satellites into space. In the future, the signal of our communication equipment will be better and better, and we can watch more TV programs on TV. At the same time, our country can also receive all kinds of signals, which is very beneficial for receiving all kinds of useful information in the future and safeguarding our national security. So this is one of the biggest uses of launch vehicles and plays a very important role.

Second, launch vehicles can transport manned spacecraft. I'm sure you can still remember the joy of all of us when the manned spacecraft landed on the moon for the first time, and we can't forget the excitement and tension of all of us when the manned spacecraft returned to Earth. Because manned spacecraft is the main tool for us to explore the unknown world, we must explore the future world through it, so launch vehicles play a vital role in this respect. It is precisely because of it that manned spacecraft can safely reach the moon and even other planets. Although it is only a transportation function, we all know the importance of transportation. Without it, the manned spacecraft would certainly be unable to move, let alone go to the planet.

Third, launch vehicles can send other satellites or space probes into specific orbits. We all know that the earth keeps spinning. If we want to receive stable signals, such as weather forecast, during the earth's rotation, we must keep a specific orbit in sync with the earth, so as to obtain accurate information. In this regard, launch vehicles play a very special role. We can use it to send some useful things to a specific orbit, because without it, we can't guarantee the accuracy of the orbit, because things in space can't be decided by humans on earth, so the launch vehicle can transport other satellites and space probes.
