Chapter 753

"That's it! We didn't do anything to lose our hearts. It's also for the future of mankind. What's the meaning of fighting on this small planet all the time? " Lei Tian Tang said with a smile.

After a few laughs, it passed. Neither Lei Tiantang nor Jiang Yuting cared. Jiang Yuting came to Lei Tiantang today and said nothing about it.

She came to ask her boss about inviting the guests to the Gaia launch site to see an experiment that is very important to the infinite gravitation group.

"Then I'll send the invitation letter according to this list when I go back. Let's do the reception work together. If some leaders come, the boss won't show up." Jiang Yuting stood up and said with a smile.

"OK, I still understand this aspect, and this experiment is of great significance to our company. I will certainly not be absent!" Lei Tiantang nodded with a smile.

They said that the important experiment refers to the Tianma spacecraft, which has been in orbit for three months. It has completed all the experimental tasks. It will take two orangutans and other experimental specimens that have been under close attention to leave the "South Tianmen" Space Station Laboratory for the most critical return to earth experiment!

Whether it is the fate of the two orangutans or whether the Tianma spacecraft can successfully return to earth, the whole world is paying attention to it. The infinite gravity group is also fully cooperating with the Gaia launch site in preparation for recovery.

The technicians who are very confident in their own technology and the company's top management want the world's attention to the company again, so that the world can witness the strength of the company again. This is the reason why Jiang Yuting came to discuss the guest list with Lei Tiantang in person.

After all, in the time node of the space race that most countries in the world are pulled in, such an experiment itself is enough to attract people's attention. If we go back to the experiment quietly, the outside world thinks that the infinite gravitation group has no confidence in its own technology, so it is very necessary to invite the media and guests to visit Yes.

After the news was published on the official website of the infinite gravitation group, it really aroused heated discussion again. You should know that the space station plan of the infinite gravitation group has been under a lot of controversy. Even if the two experimental modules of the "South Tianmen" space station have been working successfully for several months, there are still many people who are not optimistic about the plan.

The fate of the two passengers, Kaka and black pearl, in the experimental cabin of the Tianma manned spacecraft, has always been of great concern. At that time, when they were sent into space, there was a lot of controversy, so their living conditions were always of great concern.

Every time the infinite gravitation group's official website broadcast their living conditions and carry out various experiments, they will attract a lot of people to watch. We are concerned about their health problems, food problems, and so on. What's more, they are more worried about whether they can safely return to earth in the Tianma manned spacecraft experimental chamber.

"Good morning, ladies and gentlemen! Now I am at the forefront of the recovery of the Tianma manned spaceship of the infinite gravitation group, which is called the "safe return" spacecraft recovery ship!

The name of this ship is simple and clear, and it is also a large multi-functional support ship with a displacement of 18000 tons specially customized by infinite gravity group!

It is equipped with two professional heavy-duty collection and transport planes, a special high-speed air cushion search and rescue ship, four fast boats, and a specially customized recovery submarine. There are also professional medical staff and medical equipment on board, which can solve any possible problems in the recycling process!

As we all know, there are only two kinds of recovery methods for manned spaceships. One is land recycling and the other is sea recycling. Our country generally chooses land recycling. Of course, this does not mean that we can't recycle at sea. But in the past, our country's maritime search and rescue capability was much worse than that of the United States, which preferred sea recycling.

At that time, our navy lacked the aircraft carrier for aircraft taking off and landing, and the support of search aircraft for aircraft carrier takeoff and landing. If the spacecraft landed in the deep ocean, astronauts might not be able to get timely assistance!

China's re-entry module all landed on land, the main reason is that if landing at sea, the search and rescue force must be quite strong!

On the sea, if the sea conditions are relatively good and the sea is calm, then open the cabin door to lift the astronauts and rescue them. This operation is simple.

But the weather on the sea is not always calm. When there are big waves, in order to protect the safety of the astronauts, the whole re-entry module must be fished out at that time. This operation is very difficult.

Although we didn't choose to land on the sea, this problem was also considered in the design of Shenzhou. Therefore, there are also wireless signal transmitters, flashlights, mirrors, smoke cans and sea water colorants in the return capsule for emergency use!

However, there are many advantages of sea recovery. One is that the range of landing preparation can be large. As long as the sea surface can be landed, the requirement for the return accuracy of the spacecraft is low. The spacecraft or astronauts can return at any time in case of emergency, even if it is far away from the scheduled location.In addition, the spacecraft only needs to use the parachute to decelerate. When landing, the speed can be reduced to zero by using the buffer force of sea water, and there is no need to push back the engine. Therefore, the structural strength of the spacecraft is low, but the sealing performance of the cockpit is higher.

The disadvantage is that the spaceship is in danger of sinking into the water. This is an example. In 1961, after the mercury 4 spacecraft landed in the sea after suborbital flight, the return module of the spacecraft was flooded, and the astronaut Grissom almost drowned.

In addition, astronauts have a long standby time on the sea, which may cause seasickness, but these shortcomings are not an unsolvable problem for the infinite gravity group!

As for how to solve these problems, let me sell a key point. You will know when the "Tianma" lands. If you disclose too much news, your sense of expectation will be lowered. It will be scolded like a spoiler. A girl like me will not do such an immoral thing!

All right, host, this is the story ahead. Let's look forward to the moment when Tianma successfully returns! Here is the report from the safe return from the lovely swallow
