I Have a Little Black Hole

Sriharikota launch site is the most important space launch center in the three countries. The Sriharikota launch site covers an area of ​​145 square kilometers and accounts for 27 kilometers of coastline.

The launch site has test, assembly and launch facilities for large multi-stage rockets and satellite launch vehicles, as well as tracking, telemetry and communication stations for the three countries' satellites. The third brother's space agency also expanded the solid booster factory here, which can produce large-sized propellant grains for multi-stage rocket engines.

According to the news released by the Sange Space Agency, this latest polar orbiting satellite carrier rocket is 44 meters high, slightly shorter than the H-2B of Baga and the Long March 3B of Huaxia.

This latest polar-orbiting satellite launch vehicle is still a four-section rocket, and like the previous rockets, it has an alternate use of solid and liquid fuel systems.

The first section is a solid-state propulsion rocket with 138 tons of fuel (HTPB), with 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 grooves, and the fuel is dioxide tetroxide. Nitrogen and hydrazine, weighing 41.5 tons, also with asphalt to prevent rolling;

The third section has seven tons of fuel, uses solid propellant (HTPB), uses a low-angle nozzle and gyroscope (within +2 to -2 degrees) made of Kellaf synthetic fibers, and controls the deviation;

The fourth stage of the polar-orbiting satellite launch vehicle is a two-engine design and uses liquid propellant (methyl hydrazine/nitrogen oxide liquid that releases oxygen), and the polar-orbiting satellite launch vehicle is controlled by a reaction control system.

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

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

Although the maximum mass of these satellites is only 230 kg and 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. To provide high-speed Internet services, people are not rich and nowhere to spend, hype is hype, and what they do is a serious business.

This launch is in the mood of watching the excitement, and many media in many countries have adopted the form of live broadcast to live broadcast the launch. The current 5G high-speed network has also made ultra-clear live broadcast a normal news broadcast mode. Everyone Also love watching this.

My God! It's hard to believe that the third brother's launch base is so backward. Look at the equipment here. Compared with our company's 'Gaia' launch base, there is a gap of two eras! Sent by the Infinite Gravity Group An employee complained while visiting.

It can't be said that. Our company not only has the advantage of being a latecomer, but also the investment in building a launch base is several times higher than that of this base, so the difference is understandable.

Hey! 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!

What's the situation in the country! It's not a black family! Go ahead and say hello to the control center. It seems that the launch is about to start!

After following the visiting troop to their control center, the countdown to launch was about to begin, and everyone was chatting quietly while waiting for the final moment.

However, people from various countries and some private aerospace companies were obviously a little absent-minded. Everyone paid little attention to this launch, because even the third brother's space agency focused on promoting this latest polar-orbiting launch vehicle. But everyone is in this line of work, and they are very disdainful of the performance of this rocket.

Because such rocket data really cannot be said to be advanced. Compared with the current mainstream rockets in the world, its performance is not superior in any aspect.

Not to mention compared to the Infinite Gravity Group, which now occupies a leading position, and I don't know where their confidence is to surpass others.

And 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 an orbital altitude, so it is difficult to make everyone interested in such a launch difficulty.

The main reason why I came here is to give Ah Sanguo a face, and whether we can talk about some cooperation intentions in the exchanges with so many colleagues, so now everyone is sitting down and talking with the colleagues next to them enthusiastically.

In this atmosphere, along with the iconic curry-flavored English countdown, the rocket was successfully ignited and lifted into the air. After 4 of the 6 bundled auxiliary thrusters and the first section of the rocket ignited, a huge roar began to rise. empty!

After 25 seconds, the remaining two boosters were also successfully ignited, continuing to provide lift to the rocket. After the mission was completed, all the auxiliary thrusters were also successfully disengaged.

As time passed, the entire rocket flew very smoothly, and the detachment of the first rocket, the second rocket and the third rocket, including the fairing, was also successfully completed.

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

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

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

Just when the staff in the control hall changed their faces and were nervously looking for the reason, something that made them collapse even more happened. I don't know why, the remaining rockets in the fourth quarter were originally going to be given to the four massive satellites. Some of the orbital propulsion fuel suddenly leaked!

After just 2 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 rocket in the fourth quarter!

This most critical failure made the staff in the control hall dumbfounded. Many people covered their eyes in disbelief. The people in the visiting group also stood up in surprise. No one thought that they had reached this stage. Can go wrong!

You must know that in everyone's perception, since the space agency of the three countries dared to openly invite so many colleagues and the media to visit and report on this launch mission, it must have 100% confidence in this launch. Yes, otherwise, wouldn't it be a loss of adults!
