Chapter 826

Sri harikota launch site is the most important space launch center of the three countries. The Sri haricota launch site covers an area of 145 square kilometers, accounting for 27 kilometers of coastline.

The launch site has test, assembly and launch facilities for large-scale multi-stage rockets and satellite launch vehicles, as well as tracking, telemetry and communication stations of the three countries' satellites. San GE's space agency has also expanded its solid booster plant to produce large propellant grains for multi-stage rocket motors.

According to the information released by Sange space agency, the latest polar orbit satellite carrier rocket is 44 meters high, slightly shorter than H-2b of baga state and long march 3b of China.

The latest polar orbiting satellite launch vehicle is still a four rocket, with solid-state and liquid fuel systems interacting with each other, just like previous rockets.

The first section is a solid propellant rocket, which has 138 tons of fuel (HTPB), with a diameter of 2.8 meters, and its shell is made of machuan steel; the fuel of the second section is injected into two aluminum alloy tanks, the fuel is nitrogen tetroxide and hydrazine, and the weight is 41.5 tons, and asphalt is also used to prevent rolling;

the third section has seven tons of fuel, using solid propellant (HTPB) and using Kaifu Low angle nozzle and gyroscope made of fiber (+ 2 to - 2 degrees), control deviation;

the fourth section of polar orbiting satellite launch vehicle is designed with two engines, and uses liquid propellant (methylhydrazine nitrogen oxide, which can release oxygen), and polar orbit satellite launch vehicle is controlled by reaction control system.

The payload's outer shell is made of carbon nanotube and can send satellites into geosynchronous orbit, but the 130 satellites they are going to launch are all low orbit satellites.

Due to some improvements in the design, the low orbit payload of this latest type of aircraft orbit launch vehicle has increased from a little more than 3.2 tons before to 4.2 tons now. It is with this increase in payload that they are confident of launching 130 satellites at a time.

Although the largest mass of these satellites is only 230 kg, the minimum weight is only 25 kg. There are four large satellites, and the rest are small satellites. These satellites will form a satellite network in orbit to provide high-speed Internet service for mobile phone users in the three countries. People do not have money and no place to spend. Speculation belongs to speculation, and what they do is also a matter of business.

With the mentality of watching the launch, the media in many countries have adopted the live broadcast mode to broadcast the launch. The current 5g high-speed network has also made super clear live broadcast a normal news broadcast mode, and we all love to watch such content.

"My God! It's hard to believe that San GE's launch base is so backward. Look at the equipment here. Compared with Gaia launch base of our company, it's two times behind! " An employee of the infinite gravity group visited and make complaints about it.

"We can't say that. Our company not only has the advantage of late development, but also the investment in building a launch base is several times higher than that of this base, so the difference is understandable."

"Hi! If you focus on the surrounding environment, you will be more able to see the business trip. It's hard to imagine that they can assemble rockets and satellites in such a poor sanitary condition! "

"That's the national condition! No, the black one! Go ahead and tell us to go to the control center. It seems that the launch will start soon

After the visiting troops came to their control center, the launch was about to enter the countdown. Everyone was chatting quietly and waiting for the final moment to come.

However, the people sent by various countries and some private space companies were obviously absent-minded. Everyone didn't pay much attention to the launch, because even though Sange's space agency focused on promoting the latest polar orbit launch vehicle, they were all in this line of business, and they were very disdainful of the rocket's performance.

Because such rocket data can't really say how advanced, compared with the current mainstream rockets in the world, its performance is not superior in any respect, let alone compared with the leading infinite gravity group, and I don't know where their confidence is going to surpass others.

In addition, although the number of satellites launched this time has reached 130, 126 of them are small satellites of the same type, and they are still launched at the same orbital altitude. It is difficult for us to be interested in such launch difficulty.

The main reason why we came here is to give the three countries a face, and whether we can talk about some cooperation intentions in the exchange of so many peers, so now we all sit down and have a warm exchange with our counterparts.

In such an atmosphere, with the signature curry English countdown, the rocket successfully ignited and lifted off. Four of the six bundled auxiliary propellers and the first rocket ignited and sent out a huge roar and began to lift off!

After 25 seconds, the remaining two boosters were successfully ignited to continue to provide lift for the rocket. After completing the mission, all the auxiliary thrusters were successfully detached.

As time went by, the flight of the whole rocket was very smooth. The detachment of the first rocket, the second rocket and the third rocket, including the fairing, was successfully completed.In other words, the first step is not very successful.

The third brother staff of the control center were all smiling and ready for the final celebration. At this time, the accident happened!

The fourth rocket pushed all the satellites to the predetermined orbit, but the satellites above were not successfully separated!

Just after the staff in the control hall changed their faces and nervously looked for the reason, something even more collapsed happened. I don't know why. The fuel remaining in the fourth stage rocket, which was supposed to propel the four high-quality satellites to a higher orbit, suddenly leaked out!

Just two seconds after the white fuel leaked, a violent explosion occurred. The last picture the control center saw was the explosion picture from the camera on the fourth rocket!

The most critical trembling failure made the staff in the control hall look silly. Many people covered their eyes in disbelief. The visitors also stood up in surprise. No one expected that there would be problems when they came to this stage!

As we all know, since the space administrations of the three countries dare to invite so many colleagues and media to visit and report on the launch mission, they must have 100% confidence in the launch. Otherwise, it will be lost!
