Chapter 1111

Other things, even if they asked again, Jiang Ziyu and they all refused to introduce them with smile, just let them watch their landing live.

It would be meaningless to disclose it in advance. At that time, there will be many more people watching their landing and live broadcasting than now. If this kind of picture destined to be recorded in history is exposed in advance, how can people have a sense of expectation? If the Propaganda Department of infinite gravity group kills Jiang Ziyu, they can't be exposed in advance!

The live broadcast of this period will be over here. Although the infinite gravitation group will not close the live broadcasting room before the end of its mission to Mars, the eight astronauts do not have the leisure time to blow water with the netizens all the time. They have a lot of work to do.

It's not a simple job to check the landing section comprehensively, and it's not a one-time job. Take the simplest example.

When going to the regular injection or the hanging bottle, the nurses in the hospital should follow a very strict procedure. In professional terms, they should do three checks and eight pairs.

Three checks and eight pairs are medical terms. Three checks refer to the check before and after drug preparation, before dispensing, injection and disposal, and after dispensing, injection and disposal. Eight pairs refer to name, bed number, drug name, dose, concentration, time, usage and drug validity period.

You see, even a nurse's sister has to have such strict inspection procedures for an injection. It can be imagined that there are hundreds of thousands of parts in the landing cabin. If you want to ensure that these astronauts can land on Mars safely, how careful they have to check!

This is nearly 100 million kilometers away from the earth. They can only do everything on their own. They can't solve any minor problems. So when they start working, they really don't have the time to do live broadcasting, because such inspection work is not finished once.

In the next two days, more and more people paid close attention to the live broadcast of infinite gravity group's landing on Mars, and the media all started the broadcasting mode. Originally, from the perspective of private companies, this kind of broadcasting could be charged, but obviously the infinite gravitation group was not an ordinary company. They didn't need the money.

Even the media of the United States and other countries, as long as they are not habitually hacking their companies, will be able to get free broadcasting license. For infinite gravity group, the impact and significance of this landing on Mars is much more important than the cost of broadcasting.

In the eyes of the whole world, during the continuous deceleration of 18 groups of high thrust ion power stations for more than 60 hours, the space station assembly successfully reduced the speed of the space station to a lower speed on the afternoon of January 5.

Because only when the speed is reduced to a certain extent, can it enter the large elliptical orbit around Mars smoothly, and the stage of the space station entering the orbit around Mars is called "orbit capture".

Of course, even after such a long deceleration, the speed of the space station assembly is still nearly 9 kilometers per second, which is obviously impossible to enter Mars orbit at this speed.

It's not that it can't be done technically, but it's not safe to do so. There's no way to guarantee the safety of astronauts. If it's a small unmanned landing probe, you just need to start the liquid fuel engine to slow down.

However, even though the space station combination of "Mars and Mars" consumed a lot of weight in this long voyage, it still weighs more than 9000 tons, and a huge solar sail is towed behind its buttocks. With such a large weight, of course, its inertia is greater.

If it is forced to slow down at high speed, it is easy to have problems, so the whole world has witnessed its deceleration process through the cameras on the space station.

Compared with the earth, Mars is only a small point, with a mass of only 10.7% of the earth, and the gravitational influence range is very small. This requires that the space station assembly must accurately cut into the orbit around Mars, and at the same time, it must have a strong orbit change ability, so as to complete the requirements of orbit change.

Therefore, with the help of the orbital transfer engine, the space station assembly cut through the Mars gravitational orbit for three times with the help of the orbital transfer engine, and successfully reduced the speed from nearly 9 km / s to about 4 km / s by using its gravity, which successfully verified the effectiveness of this technology with practical actions!

Because with the help of this multiple entry deceleration technology, the speed of the space station assembly is reduced to this speed, and the space station assembly can make the most critical step under the condition of ensuring the safety of astronauts.

When the space station complex was re orbited back 300 kilometers from the surface of Mars with the help of orbital transfer engines, its flight speed had been reduced to about 3 kilometers per second under the continuous operation of six liquid fuel engines.

After three times of high-speed approach to Mars, the 8 astronauts on the space station assembly are confident, so at this last critical moment, they still completed all the formal orbital operations in ultra-high working state.

Finally, with the help of all the engines, the speed of the entire space station slowed down to 2 kilometers per second. At this speed, the space station assembly was successfully captured by Mars gravity and entered a large elliptical orbit with a cycle of 35 hours around Mars.And so on, commander Zhang Chuanguo solemnly reported through the live camera that "the Mars satellite" space station combination has successfully entered orbit around Mars After that, all the people who saw this scene couldn't help clapping!

Because the importance of this step is even more important than the next landing module landing on Mars. After all, if the space station combination can't even enter the Mars orbit, then there is no need to talk about the later things.

At this stage, everyone in the control center on the earth side is relieved. Although there are still many steps to be completed, the completion of the space station's official entry into Mars orbit means that the company has worked hard for several years, and the Mars colonization plan that has spent more than 250 billion people's dollars is not a failure!

Because at this stage, even if the later mission to Mars fails, the work of the space station on Mars orbit can still be carried out, and relevant scientific experiments can still be done in the space station, but the manned landing on Mars has not been completed.

And even if the landing fails, it's no big deal, because the safety of astronauts can be guaranteed, and the relevant data about why the failure can be collected to provide data support for subsequent missions.
