Towards the end of 96 years, the work of the research institute is more, whether it is the research and development of various systems, but also the rocket launch work.

Even Liang Yi, who is in charge of finance and business negotiations, has been busy during this time.

It is not only responsible for sorting out the financial expenditures and revenues of the Rocket Research Institute this year, but also responsible for supervising and urging many subordinate factories and experimental centers to submit their financial reports.

In addition, he is also responsible for the commercial negotiations of some research institutes, and recently a small country in Southeast Asia intends to launch their first developed satellite with the help of a dragon country's rocket.

From time to time, Liang Yi has to travel to Yangcheng to hold various consultations with their representatives.

Several times throughout the Rocket Research Institute, perhaps the most idle person is Zhang Xingyang.

The design work of the new rocket, the direction he has secretly told Geng Bo, who has been having a headache before.

The research and development work of the rocket propulsion system, since the help of the supercomputer whose performance is not very advanced two days ago, has basically determined the layout of the engine, and the progress is quite good.

Zhang Xingyang has been more concerned about the preparation of the launch missions of the two "Iridium" signed with Iridium in the past two days.

After all, this is the first and only opportunity to launch a satellite of a foreign company this year.

If the launch of Iridium goes well, it will be a happy situation for all. Foreign capital companies found ways to reduce costs, and rocket research institutes were given enough profits and enough opportunities for launches.

If the launch fails, it will be nothing more than an increase in costs for foreign capital companies, but for the rocket research institute or the domestic aerospace industry, the blow will be a bit big.

The more opportunities there are to launch, the faster the growth will be, after all, many technologies need to be in operation to be fully validated.

For example, the "Energy" rocket developed by Mao Xiong before has only carried out two launch missions in total, and many technologies have not been perfected successfully.

And after the fall of the woolly bear, along with the fact that such a heavy rocket is no longer needed, the "Energy" rocket will no longer be useful, and the opportunity to perfect the technology will be lost.

Therefore, it can be said that this launch is related to the launch of domestic rockets, and whether it can open up the international market.

As for the rocket that launched the two "Iridium" this time, it is the Chang-3B rocket that has just been tested in combat last month.

In the last test launch, the Changsanyi rocket has shown good performance, and the bridging between various systems is also relatively good.

There was no ignition failure of the three-stage rocket engine like when the Chang-3 rocket was launched before.

This can basically be seen that in the process of rocket manufacturing, after the implementation of the double zero system, the quality level of the finished product has been greatly improved.

Rocket manufacturing is related to hundreds of manufacturers, and being able to do this in this era also means that the processing capacity of the industrial base has also improved a lot.

Of course, all this is not without a price, in order to smoothly promote the double zero management system, Zhang Xingyang in the past half a year, because of various technical problems, management problems, into the prison stepping on the sewing machine, there are hundreds of people.

As for the others, the total number of people who have suffered various demotions, salary reductions, and fines can add up to thousands.

It is precisely such severe punishment and the unstoppable propaganda work that has not stopped paying attention to product quality throughout the space system.

Only then can the rocket maintain a 100% parts pass rate when it leaves the factory.

It is precisely because of such strict quality management that Zhang Xingyang can have strong confidence in the launch of "Iridium".

I firmly believe that this Changsanyi launch mission can be a complete success.

The Iridium launched this time was produced by Motorola, and of course they are one of the many supporters behind Iridium.

At this time, Motorola has not fallen off the altar like the era of smart phones, and still maintains its position as a giant in the field of communications.

The two satellites weighed more than 700 kilograms, and the transportation method was that Iridium had the deep pockets to directly charter a Boeing plane to transport the two satellites across the ocean.

Although the launch base sometimes undertakes commercial launch missions, it does not allow unrelated people to enter the launch base, so after the rocket arrives.

The whole process is carried out by the domestic government, responsible for transportation, testing and other pre-launch work.

With the two "Iridium" satellites loaded into the fairing of the rocket, the entire rocket launch mission officially entered the countdown in hours.

At the launch site in December, even Xichang, which is like spring all year round, seems to have a bit of a solemn atmosphere, and the grass and trees are withered and yellow.

This is a new launch site that has just been built for a short time, and the previous launch site is no longer in a usable state due to an accident at the beginning of the year.

The construction of the new launch site was mainly paid for by the Rocket Research Institute, after all, the loss of the launch site was caused by the Rocket Research Institute last time.

The new launch site and control centre have been significantly more demanding in all respects, withstanding the intensity of a magnitude 9 earthquake, and the building's high-grade concrete walls are up to three meters thick and can withstand the blast of tons of TNT head-on.

This is also a special request of the Rocket Research Institute, it is the loss of personnel caused by the last accident, so Zhang Xingyang has to ask for this, he doesn't want to see anyone die because of the accident again.

With the completion of refueling, the personnel were withdrawn from the launch site.

The auxiliary rack next to the rocket slowly retracted, and it was time for the launch to really count down in minutes.

On the huge electronic screen, a bright red countdown is constantly beating.

Soon the time came for the launch.

The little brother in charge of the countdown of the voice broadcast said methodically:

“10！”

“9！”

......

“3！”

“2！”

“1！”

"Ignition!"

The operator presses the bright red button that symbolizes the launch of the rocket, and a powerful jet of flame is ejected from the bottom of the rocket, slowly propelling the hundreds of tons of rocket into the air.

Accompanied by radar stations in various places that track the trajectory of the rocket, the operation of the rocket is transmitted back.

Zhang Xingyang was still a little apprehensive, but calmed down slightly.

"The separation of the first stage rocket was successful!"

Many engineers in the control center were busy with their work, and soon the rocket reached the sky over the ocean.

"Far side six, radar tracking is normal!"

"The two-stage rocket was successfully separated!"

At this time, the altitude of the rocket has basically come to the vicinity of the Earth's low earth orbit.

"The three-stage rocket engine was successfully ignited!"

"Star Arrow Separation Successful!"

The two "Iridium" satellites have successfully entered the predetermined orbits, and the domestic rocket launch mission has been successfully completed at this point.

After all, they bought rocket launch services for satellites.

Everyone in the control center no longer has the same excited expression as after the last successful launch, but everyone is still very happy after the successful launch of the satellite.
