I have a little black hole

The Sri Harikota launch site is the most important space launch center of the three countries.The Sri Harikota launch site covers an area of ​​145 square kilometers and covers a coastline of 27 kilometers.

The launch site has large multi-stage rockets and satellite launch vehicle testing, assembly and launch facilities, as well as tracking, telemetry and communication stations for the satellites of the three countries.Sange's space agency also expanded its solid booster plant to produce large-sized propellant grains for multi-stage rocket engines.

According to news released by Sange Space Administration, the latest polar-orbiting satellite launch vehicle is up to 44 meters tall, slightly shorter than the H-2B of Ba Ga and the Long March 3B rocket of China.

This latest polar-orbiting satellite launch vehicle is still a four-section rocket, and has the same solid-liquid fuel system as the previous rocket.

The first section is a solid propellant rocket with 138 tons of fuel (HTPB), a diameter of 2.8 meters, and the shell is made of horse nail steel; the fuel of the second section is injected into two aluminum alloy tanks, and the fuel is dioxide Nitrogen and hydrazine, weighing 41.5 tons, also use asphalt to prevent rolling;

In the third section, there are seven tons of fuel, using solid propellant (HTPB), using low-angle nozzles and gyroscopes (within +2 to -2 degrees) made of Kelaf synthetic fibers, to control deviation;

The fourth section of the polar orbit satellite launch vehicle is a two-engine design and uses liquid propellant (a liquid that can release oxygen from methyl hydrazine nitrogen oxide). The polar orbit satellite launch vehicle is controlled by the reaction control system.

The outer shell of the payload is made of carbon nanofiber tubes and can send satellites to geosynchronous orbit, but this time the 130 satellites they are launching are all low-orbit satellites.

Due to some improvements in design, the low-orbit payload of this latest type of orbital launch vehicle has increased a little from 3.2 tons to 4.2 tons now. It is with this increase in load that they are confident to come Launch 130 satellites at once.

Although the maximum mass of these satellites is only 230 kg, the minimum weight is only 25 kg, there are 4 large satellites, and the rest are small satellites. These satellites will form a satellite network in orbit for mobile phone users in the three countries. Providing high-speed Internet service, people don't have money and no place to spend. Hype is the hype, and the work is just right.

This launch is lively, and there are still many countries that have used live broadcasts to broadcast this launch. The current 5G high-speed network has also made Chaoqing live broadcast a normal news broadcast mode. Also 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. It's a gap between our company's "Gaia" launch base and the two eras!" Infinite Gravity Group has sent An employee vomited while visiting.

"Can't say that, our company not only has the advantage of latecomers, but also invests in building a launch base several times more than this base, so the difference is understandable."

"Hi! If you focus on the surrounding environment, you can see the difference even more. It's hard to imagine that they can assemble rockets and satellites in such a poor place!"

"It's the national situation! It's not black people! Let's go ahead and greet us to the control center. It seems that the launch will start soon!"

After following the visiting large forces to their control center, the launch is about to enter the countdown, and everyone is chatting in a quiet voice while waiting for the last moment to come.

However, people from various countries and some private aerospace companies are obviously absent. Everyone does not pay much attention to this launch, because even the third brother’s space agency emphatically promotes this latest polar orbital launch vehicle. But everyone is doing this business, and they are very disdainful about the performance of this rocket.

Because such rocket data can't really say how advanced it is, compared with the current mainstream rockets in the world, its performance is not superior in any way, let alone the infinite gravity that currently occupies the leading position. Compared with the group, they do not know where their confidence is to surpass others.

Moreover, although the number of satellites launched this time has reached 130, 126 of them are of the same type of small satellites, and they are still placed at an orbital height. It is difficult to make such a launch difficult for everyone to be interested.

The main reason for coming here is to give A Sanguo a face, and whether he can talk about some cooperation intentions during the exchange of so many peers.

In this atmosphere, with the iconic countdown of curry-flavored English, the rocket successfully ignited, 4 of the 6 bundled auxiliary thrusters and a huge roar after the first rocket fired began to rise empty!

After 25 seconds, the remaining two boosters also successfully ignited and continued to provide lift for the rocket. After completing the mission, all the auxiliary thrusters were also successfully separated.

The time passed by one minute and one second, the entire rocket's flight was also very smooth, the first section of the rocket, the second section of the rocket and the third section of the rocket including the fairing were also successfully completed.

In the fourth quarter, the rocket also successfully ignited, pushing the satellite to a predetermined orbit. At this point, it is reasonable that the basic problem is not big, but this is also reasonable.

The three brothers in the control center were all smiling and preparing for the final celebration. It was at this time that an accident happened!

In the fourth quarter, after pushing all the satellites into a predetermined orbit, the above satellites were not successfully separated!

When the staff in the control hall changed their faces and looked for the cause nervously, something happened that caused them to collapse. I don’t know what the reason was. In the fourth quarter, the remaining rockets had to give the 4 massive satellites higher. Some orbital propelled fuel suddenly leaked!

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

The most critical and trembling failure made the staff in the control hall dumbfounded. Many people covered their eyes in disbelief. The people who visited the group stood up in surprise. Can go wrong!

You should know that in the perception of everyone, since the space agencies of the three countries dare to openly invite so many colleagues and the media to visit and report on this launch mission, they must have 100% confidence in this launch. Yeah, otherwise it’s just to lose your adult!
