Chapter 1920: Walker 3 unmanned cargo experimental spacecraft

In the Xinyuehu Aerospace Command and Control Hall, there were only ten minutes left before the launch. Wu Hao and the others had already returned to the hall, watching with full attention.

The signals they saw came from the internal signals of the aerospace system and were synchronized with the signal data in the launch command and control hall in the South China Sea, so they could see the latest data information in real time.

Although the launch took place in the dark night, CCTV still chose to broadcast it live and invited relevant experts to interpret it. On the beach opposite the Nanhai Space Launch Center, a large number of tourists had gathered to watch the rocket launch.

This seems to have become a tourism industry here. Every time the rocket is launched, the place is overcrowded and extremely lively.

There are even special travel agencies that organize rocket launch tours to organize tourists to watch rocket launches. If you encounter an important rocket or spacecraft launch, tour tickets are even more popular and hard to find.

This seems to have become an important channel for many space and rocket enthusiasts to understand the launch time of the rocket, because tourist groups often announce the launch time to attract tourists.

These space and rocket enthusiasts will use this information to study and determine what rocket to launch, what spacecraft to carry, etc.

Ten minutes to prepare!

As the announcement sounded and the siren beeped, the last section of the rotating platform protecting the Jianmu-7 on the launch tower slowly opened, revealing the true appearance of the Jianmu-7 launch vehicle.

Compared with the previous Jianmu-7 rocket, it is very different. The Jianmu-7 rocket launched this time does not have a huge fairing section. In the same way as the Falcon rocket carries the Dragon spacecraft, the Walker manned spacecraft

It is also installed directly on the top of the Jianmu-7 two-stage rocket.

Without the fairing protection, everyone can clearly see what the Walker unmanned experimental spacecraft looks like.

In the Xinyuehu command and control hall, the atmosphere has solidified to the extreme at this time. Because it is often the last few minutes before the rocket is launched that situations are most likely to occur.

So at this time, everyone is fully focused and paying close attention to every beating data information on the screen, making sure not to miss a drop.

Five minutes to prepare!

As this announcement sounds, it means that the Rockets have entered the final countdown stage.

Under normal circumstances, low-temperature hydrogen and oxygen rockets will emit white water vapor smoke at this time. However, Wu Hao's Jianmu series rockets will not, because they use self-developed semi-solid foam propulsion fuel

.This kind of fuel does not require low-temperature storage, is in a semi-solid state, and does not produce pollution after combustion. It is a very clean and efficient new propulsion fuel.

One minute to prepare!

As this announcement sounded, I saw that the data pendulum linking to the rocket on the launch tower had been opened and the cables removed. This meant that the rocket had entered the autonomous operation stage and no longer needed external command information or power supply.

Fifty seconds!

Forty seconds!

Thirty seconds!

Twenty seconds!

Ten, nine, eight...three, two, one!

Fire up and take off!

001 milliseconds!

Program turns!

As a huge flame erupted from the tail of the Jianmu-7 rocket, a huge sound wave swept over.

I saw the rocket taking off slowly like clouds and mist.

On the TV screen, on the beach opposite the launch site, tourists watching the launch burst into cheers.

As for the Xinyuehu command and control hall, all the technical staff, including Wu Hao, burst into warm applause and laughter.

Driven by the huge tail flame, the rocket continued to accelerate and climb, shooting straight into the moonlit sky with sparse stars.

Through the surveillance cameras on the rocket, the large screen displays the surveillance images transmitted from the rocket body and ground engine. These cameras will always monitor relevant data information during the flight of the rocket, thereby helping technical staff to understand and control

The flight status of the rocket.

Of course, even if the rocket fails at this time, the ground launch command and control center has no way to intervene. Everything must be resolved by the rocket's own flight control system.

Therefore, at this time, it is best if there is no other sound in the quiet hall except related data broadcast. Because once the sound appears, it means that there may be a problem with the rocket.

Because once a problem occurs, there is no way for the ground to intervene and solve it. The only thing that can be done is probably the self-destruct button.

In fact, this button is always at hand of the controller. Once an emergency occurs and it is determined that the rocket cannot be saved, the controller will immediately open the protective cover and press the self-destruct button.

A faulty launch vehicle will self-destruct in mid-air. This will also prevent the faulty rocket from falling down and exploding, causing greater harm and disaster.

After the rocket was successfully ignited and launched into space, Wu Hao and the others relaxed a little. For many things, the last moments before starting are the most stressful, but once they start, they will become calmer and more relaxed.

I was so nervous just now. Although we have seen this rocket launch countless times, every launch still makes people extremely nervous, for fear that something will go wrong at the last moment. Zou Xiaodong patted his chest and said with a smile.

Yang Fan smiled and joked after hearing this: "Are you not nervous? The rocket and the spaceship together cost tens of millions. If fireworks are really set off, all the money will be wasted. This may become the world's biggest problem."

Put on the most expensive fireworks.”

Bah, bah, bah, the launch is not over yet. It is most taboo to say this word at this time. Zhang Jun bah several times, then showed a hint of dissatisfaction at Yang Fan and Zou Xiaodong and said: "You two, don't pay attention when you are joking.

Point to occasion and time.”

When Wu Hao heard this, he smiled and waved his hand to signal Zhang Jun to calm down and said: "Okay, there is no one else here, just say what you say. But if you really go to the scene, don't say that, you may easily get beaten by a group."

You have to know that this word is the last thing anyone involved in launching launches wants to hear, so whoever says it is in a hurry."

Hehehe... Hearing Wu Hao's joke, everyone present laughed and the atmosphere relaxed.

Just as he was talking, the latest report came over the radio.

The first and second stage rockets separate!

In the black and white telemetry screen, with a burst of fire, the first and second stages of the rocket were successfully separated. The second stage rocket continued to push the Walker 3 unmanned cargo experimental spacecraft to climb, while the first stage rocket slowly moved downwards.

landing.

This scene was also captured by surveillance cameras installed on the second-stage rocket body and in the tail engine compartment.

The first-stage rocket grid plate opens and begins to slow down!

At this time, the picture on the big screen switched to two parts. One part continued to show the picture of the Jianmu-7 second-stage rocket that continued to rise and the Walker-3 unmanned cargo experimental spacecraft at the top.

The other part is switched to the related pictures of the landing Jianmu-7 first-stage rocket and the rocket landing platform in the South China Sea.
