Chapter 728

The lunar lander 2 in front of us is a backup probe. It is now in the same package as the one that is ready to launch and has been installed in the julingshen-2 heavy-duty recoverable rocket, so as to ensure that in case of failure of the launch of No.1, it can be launched again in the shortest possible time, without delaying the time node of the exploration plan.

Of course, even if No. 1 is successfully launched, it doesn't mean that this No. 2 is of no great use. The moon is so big. If you want to complete its exploration, you need to rely on a landing probe. Even if the landing probe weighs 14.7 tons, it carries several kinds of probes and related experimental carriers, but the relevant exploration mission wants to In order to complete the task efficiently, more landing probes must be added to the task.

This weight may not be well understood by us. As we can see from China's chang'e-3 mission, like the chang'e-3 probe, the Moon Palace Pathfinder is also composed of a lander and a Rover (commonly known as the Lunar Rover). After landing on the lunar surface, the payload carried by the detector will carry out scientific exploration under the support of the TT & C system and ground application system.

However, the total weight of chang'e-3 is only 3780 kg. If the deceleration fuel and other weights are excluded, the dry weight of chang'e-3 is only 1220 kg, and the weight of Yutu lunar rover is only 140 kg. By comparison, we can know what the total weight of 14.7 tons is?

The total weight is nearly 4 times faster than that of chang'e-3, and the dry weight is 10.4 tons. To know that a heavy tractor usually weighs 8 to 9 tons, its dry weight is even heavier than that of a heavy truck. It can be imagined how much more detection equipment and experimental carrier can be carried!

But even so, the detection range of a landing probe is very small, but the range of the moon needs to be explored is so large, there are all kinds of geological conditions, so it is definitely not possible to rely on it alone. Therefore, even if the No.1 probe is successfully launched, the No.2 standby probe will also be launched to different areas of the moon to carry out exploration missions.

Because of this, it's packed, so it's impossible to reopen it for Lei Tiantang's visit, so after learning about the situation, Lei Tiantang followed Zhang hanxiu to visit the Mars lander with Kaila, but the testing work of the Mars lander of "new homeland pioneer" has been going on Yes, there is more to see.

After satisfying his curiosity, Lei Tiantang could not continue to disturb Zhang hanxiu's work. He took Kaila to stroll around the base, and would like to go back and have a look at the official launch.

Of course, the launch mission has also attracted the attention of the media. Although lunar exploration has not been a new thing for a long time, it can only be completed by the national power to complete such a complex system engineering. This time, a private enterprise like infinite gravitation group will also carry out such a lunar exploration project. Its own news coverage is very high, what's more The name of this enterprise is infinite gravitation group!

This name represents the news attention! However, since the launch has not yet started, there are not many reporters on the scene. However, the early reporters have not failed to live up to their waiting. The scene of Lei Tiantang and Kaila showing up can also attract a wave of attention.

However, even if the launch is successful, we will pay more attention to it a while ago, because we are most concerned about whether the probe can successfully land on the moon, which is the symbol of the real success of the launch mission.

With the attention of reporters and netizens, the julingshen-2 heavy-duty recyclable rocket, which was bundled with two auxiliary boosters, rose from the ground in a huge roar, crossed a beautiful arc and lifted off smoothly. The "Moon Palace Pathfinder" 1 probe was directly launched to the Earth Moon transfer orbit at the apogee height of 200 km and the apogee height of 380000 km.

Next, it will take a few days to reach the moon, when the official landing process will start, and we will pay attention to that time, but even if it is successfully launched, it is a very encouraging achievement.

Xiong Antai, Zhang hanxiu and all the participants in the project were very excited. In addition to the necessary on duty monitoring personnel, others held a small celebration with Lei Tiantang in the canteen that night. Of course, the more important celebration was to wait until the landing probe successfully landed on the surface of the moon and officially started work Then all the staff can participate in it!

"Welcome to our Gaia base for inspection." Lei Tiantang smiles and greets the leaders who come to visit the probe landing operation with the company's top management in the base.

It has been several days since the successful launch of the Moon Palace pathfinder-1 probe. The probe flew very fast. In less than five days, it arrived near the moon. The probe began to ignite and slow down. After the main engine ignited for about 5 minutes, the probe successfully entered the 100 km x 400 km elliptical orbit around the moon.

This means that the landing procedure is about to start. At this time, the attention of the mission is very high. Even many leaders have taken time out of their busy schedule to witness the last step. This is not to satisfy curiosity. The leaders who have seen the landing of the lunar lander have seen nothing strange.After all, no matter which company has visited the company for a month, they should be encouraged to participate in the company's history!

The most important point is that the state side is also deeply involved in the launch mission of the infinite gravitation group. As early as the design of the "Moon Palace Pathfinder" 1 probe of the infinite gravitation group, the state provided a lot of help to the mission. The successful experience of the Chang'e series mission was sent without reservation, which made the deep space laboratory go a lot less curving road.

In the future, it also provides a lot of help in the subsequent design of the probe. Of course, the new design of infinite gravity group also provides more possibilities for the country's follow-up lunar exploration plan. The technological exchange and progress are achieved in such cooperation, which can be regarded as a model of in-depth cooperation.
