Weibo, the top hotly searched terms on July 7:

"Lin Ju's first night in space"

At noon on July 6, Lin Ju arrived at the Tiangong Space Station.

Although he has not been in space for many years and has never had docking experience, repeated training with countless repetitions is effective. Li Wei's manual docking is faster than automatic docking, and he can firmly connect to the interface in one go.

Lin Ju, who had been floating in space for more than two hours, had adapted to gravity and followed Li Wei into the "Tianhe" core module.

The 0.9m docking port of the Yungong core module is occupied by Shenzhou 11 and Unity, so it can only be entered through the node module of the Tianhe core module.

System engineers Ke Yun and Deng Lei were waiting for him at the Yungong Space Station. When Lin Ju passed the wide 2.5-meter square interface, they shouted in unison:

"Welcome home boss!"

There is no problem. XS-62 is manufactured and owned by Xinyuan Company. It is not wrong to say that it belongs to Lin Ju.

In other words... he owns a house in space?

Although Lin Ju has entered the space station more than once on the ground, this is his first time in space.

What struck him most amazingly was the sense of direction, especially the circular cabin part.

The first thing he did was to step lightly on the bulkhead and walk around. Because there was no gravity, there was no discomfort at all.

The actual living experience in the 6.8-meter circular cabin is extremely huge. With Lin Ju's height of 1.8 meters, he is three and a half as tall!

So much so that during the live broadcast again in the evening, Lin Ju subconsciously complained:

"Had I known it, I would have made it into partitions. Both floors would be rich."

At that time, the online comment area was full of terms such as "As expected of a big capitalist" and "Capital is going to enter space", but everyone really didn't think there was any problem. After all, the average floor height of residential buildings is only 2.8 meters to three meters. about.

The height of 6.8 meters is not an exaggeration to say that it is a villa, so until now, some people have been complaining that the XS-62 is too luxurious and extravagant, and it has no compartments.

But these Xinyuan engineers at the time were not unimagined, but at that time they believed that the layout of the circular cabin would greatly improve the comfort and give people the same feeling as a spacecraft.

In fact, this is indeed the case. Lin Ju’s feeling in the circular cabin is a complete feeling of a future spaceship. The space is grand and the layout is beautiful, especially when sitting in the observation cabin. If a ring-shaped operating console is added, it will be perfect. It's like sitting in the pilot cabin of the "Millennium Falcon" spacecraft, it's very special.

On the contrary, when he went back to visit the Tiangong-2 Space Laboratory, he instantly felt as if he had entered a container, and his impression was extremely depressed.

He heard that after the first four astronauts from the Tiangong Space Station came down, engineers from the Fifth Academy complained unintentionally while manufacturing the cooperative experimental module at the B-level base.

Astronauts who have experienced the Yungong core module strongly recommend that the internal size of the future space station should not be less than 3X3 meters, and preferably 4X4 meters, because once you experience the spacious environment, you really can't go back.

Even with their adaptability, it will take a long time to change, and there are really many advantages to large cabins.

Therefore, the fifth batch of the "Mengtian" and "Wentian" experimental cabins of the second batch still followed Xinyuan's "waste" spirit and left a lot of space, without crazily cramming equipment.

It was his first time to experience a space station, especially a home-built space station. Lin Ju kept running around until he rested according to the schedule specified by the space station, and even picked a mature cabbage...

Some of these videos were recorded by the space station's live camera and released to the public. Regarding celebrities' first experiences on the space station, these videos have received very high views and many complaints.

After all, according to daily practice, celebrities should have certain qualities as the media said. However, Lin Ju's performance seems to be no different from ordinary people. He will be surprised when seeing some magical phenomena in the state of weightlessness, and he will make many observations. Use very childish movements to experience the magic of weightlessness.

And these actions also caused some unexpected effects:

Jeff Bezos announced within Blue Origin that he will develop the "New Shepard-2" rocket. Unlike the "New Shepard", the New Shepard-2 rocket will use a BE4 engine with the goal of being able to Launch the weight-reduced space capsule into low-Earth orbit.

After all, the comparison between the experience of being weightless for a few minutes and the experience of being on track...well, obviously the latter is more powerful.

Lao Ma is eyeing the space station. SpecaX announced that it will jointly develop an inflatable cabin with Bigelow Aerospace. It will be launched to the ISS using a Falcon 9 rocket. After docking, it can be inflated and expanded to become a full-time tourist cabin for external operations.

The expanded area of ​​this inflatable cabin section "Origin" reaches 115 square meters, which is smaller than the XS-62, but not much smaller.

The advantage is that the size and weight are relatively well controlled. Bigelow received assistance from NACA ten years ago, and the technology is relatively mature. However, reliability has always been a concern, but now they have decided to add more efforts to make it more reliable. The inflatable cabin section is put into use in advance.

…

"my country's new generation manned spacecraft test vessel completed its first test flight."

On July 8, while Lin Ju was still floating in the sky, the new generation manned spacecraft completed its first test flight.

The launch rocket is the Long March 3B, a large-capacity LEO with a capacity of 11.2 tons.

The new-generation manned spacecraft, which weighs 21.6 tons and is 8.6 meters long, is launched with the Long March 3B. Of course, it cannot reach low-Earth orbit, but it is just to test the performance of the spacecraft. It only needs to fly to high suborbit and let the spacecraft be burned by the atmosphere twice. The design was successful if there were no problems.

Originally, Xinyuan-5A could just hit low-Earth orbit, but the space agency felt it was unnecessary, and the Long March 2 and 3 series rocket bodies were in large inventory, so there was nothing to do.

However, the diameter of the new generation manned spacecraft has reached 5 meters, while the maximum diameter of Long March 3B is only 3.35 meters, and the diameter of the reusable Long March 7 planned to be used in the future is also 3.35 meters.

There is no problem if the diameter exceeds a little, but because the new generation manned spacecraft adopts a fairing-less design, there is also no transition between the bottom and the rocket.

This results in the spacecraft's head looking... a bit meaningful anyway.

Fortunately, the test of the spacecraft itself was very successful. The design of the new generation manned spacecraft is very complete, and the reusability index has been fully achieved. The impact of ablation is not great, and there is no problem in simply cleaning it up and launching it again.

Many new technologies adopted by the spacecraft have also been verified, including flexible cargo compartments, air cushions during landing, etc., and there have been no major problems. This means that the expensive Shenzhou era is about to pass, and the space agency will usher in an era of reusable and cheap space. .

However, this news did not cause much disturbance in the aerospace industry or even in the technology circle. The hot topic now is computers: ternary computers.
