As the fairing opens, the second-stage rocket continues to work. It will send the Lunar Cargo 2 spacecraft on its final journey, sending the spacecraft to the Earth-Moon transfer orbit.
This is the advantage of high-thrust rockets. Unlike those small-thrust rockets, they cannot send the spacecraft directly to the Earth-Moon transfer orbit. Instead, the spacecraft needs to change its orbit bit by bit before it can enter the Earth-Moon transfer orbit.
High-thrust rockets do not need these. They can send the spacecraft to the required orbit at once.
Just like Third Brother, it takes more than ten days for its rocket to send its lunar probe to the moon. Wu Hao and others or other countries only need four or five days with their high-thrust rockets. This is the gap.
Because it adopts a more efficient Earth-moon transfer orbit, this lunar cargo spacecraft only takes four days to reach the lunar orbit, which is one or two days faster than the transfer time of other spacecrafts, and longer than Sanguo's.
It's several times faster.
Through the external camera on the Lunar Cargo 2 spacecraft, the beautiful Earth is displayed in the picture. The morning and evening lines below clearly separate the day and night. On the edge of the arc-shaped skyline, a dazzling sunlight is slowly rising.
rising.
On the other half of the screen, the height of the core first-stage rocket and the two boosters are getting lower and lower, and the tail flames ejected by the tail engines of the three rockets are getting longer and longer, and the sound is getting louder and louder.
The three rocket bodies, like three gods, slowly descended from the sky under the attention of many tourists. As the altitude became lower and lower, the roar from the rocket engine was no weaker than when it was launched.
This also made everyone at the scene cheer.
On the ground, three circular landing sites arranged in a row are ready. The outlines of the three landing sites are selected, and the cluster spotlights also allow everyone to see the entire landing site clearly.
Through the external surveillance cameras on the three rocket bodies, everyone can clearly see that the three rocket bodies are getting closer to the landing site below.
As the height of the three rocket bodies dropped lower and lower, the landing gears on the rocket bodies slowly folded outwards, lowered and opened. The speed of the rockets also became slower and slower, until they landed smoothly on the ground.
The engine then slowly turned off, and bursts of white smoke rose.
good!
Bang bang bang...
This scene made everyone cheer. Whether it was the tourists watching, the audience watching the live broadcast, the staff in the command and control hall, or even Wu Hao and others watching in the office, they all cheered.
.
This scene is worth being happy and cheering for!
While everyone was cheering, they slowly switched to the aerial recovery team. Although it was late at night, through the infrared camera and night vision camera, Strike could clearly see the two halves of the fairing slowly gliding towards the sky.
.
The two fairing halves began to glide and descend towards the predetermined area one after the other, and the three helicopters that had been waiting for a long time began to fly towards it.
Through the images transmitted back by the infrared night vision low-light lens of the high-altitude patrol drone, the real-time dynamics of the two fairings and the three helicopters can be clearly seen. In fact, the entire aerial recovery team also used the drone to
The real-time data sent back by the human machine is used to make adjustments and command the helicopter to recover.
Especially this kind of night recovery work, the visibility is relatively low, so the risk is very high, so you must be extra careful.
As the first half of the fairing glided to the predetermined distance, the No. 1 helicopter began to increase its altitude and began to follow the fairing paraglider. It found the right position and quickly cut in from behind. Control the crane suspended below the helicopter.
Hook, accurately hook the paraglider on the fairing.
There is only one chance. If a mistake is made, the chance of being allowed to do it a second time will be very small. Because the huge wake of the helicopter propeller will blow over the paraglider on the fairing, the whole process must be done quickly, accurately and in one go.
However, this is no problem for experienced pilots who have completed dozens of recovery missions. I saw two helicopters very cleanly using the hooks hanging under the helicopters to glide the fairings.
The umbrella was hooked, hung under the helicopter, and then flew to land.
On the other half of the screen, as the height of the rocket gets higher and higher, the whole picture of the earth is gradually displayed on the screen. Although everyone has seen this kind of picture more than once, it is extremely fascinating every time it is seen.
Moving.
This is the earth, the home of mankind, it is so beautiful.
It is hard to imagine that there is such a planet in this vast universe. It is hard to imagine that life, human beings, and such a brilliant civilization would be born on such a planet.
The working time of the second-stage rocket is very long. The time on the big screen has reached more than 3,000 seconds, which is much longer than the working time of the first-stage rocket.
The reason why it can work for such a long time is because the rocket has pushed the spacecraft into space. Although it is still getting rid of gravity and continuing to rise, the thrust and fuel required are naturally not as powerful as in the atmosphere. Using the centrifugal acceleration of the earth, through
Variable engine technology can adjust the thrust of the engine so that the rocket can continue to work and push the spacecraft into the Earth-Moon transfer orbit.
Now, everyone is waiting for the arrival of this last exciting moment. Whether it is the launch system or the technical staff of Haoyu Aerospace, or the tourists still gathering on the beach who are unwilling to leave, as well as the viewers who watch the live broadcast through various methods
They, as well as Wu Hao and others in the office, are all waiting for the last and most critical step in the launch process.
Once again, everyone felt the slowness of time. Time that usually seems to fly by has become extremely slow at this moment, so slow that it makes people a little irritated.
As the scheduled time came, everyone stared at the big screen attentively, waiting for this crucial step to arrive.
Suddenly, the external camera of the lunar cargo spacecraft on the big screen froze, and the second-stage rocket at the tail began to separate and fall away, and gradually moved away.
At the same time, the external camera on the second-stage rocket body also captured this scene. The entire Lunar Cargo 2 spacecraft was facing the bright sunshine, gradually moving away from the earth and heading towards the moon in the distance.
"The second stage rocket shuts down and the weapon and arrow separate!"
Bang bang bang...
As the announcement sounded, the missions who had been waiting for this moment for a long time cheered. At this moment, everyone, not only the staff involved in the entire launch mission, not only the tourists, not just the audience, not just Wu Hao, everyone was waiting for
I am happy and happy about the victory and success of this launch mission!
