The results are very encouraging.

Even if the cost of the last Tengyun will exceed 3 billion yuan, it is much faster to use it in terms of convenience and response speed.

Even though the economy of a single flight may not have an advantage over traditional ships – or even more – it cannot be denied the significance of what Tengyun represents: it is an SSTO.

Single-stage flight into orbit, without abandoning anything except fuel, can also return to the ground with all the tails!

It almost ushered in a new era of the space age, and such a product may be a little troublesome in the early stage, but the prospects are unimaginable.

To tell the truth, the space agency was very apprehensive when the Tengyun project was changed from two-stage orbit to single-stage orbit, and extended the time expectation from 2025 to 2030, and even 2035 is acceptable, no one expected that this thing was progressing so fast, and it has reached the point where it can set targets!

The big guy straightened up with some excitement: "Great, great, when will it be able to fly, and will it be able to build a verification machine for the first time this year?" ”

Lin Ju nodded: "Yes, Seryov plans to build two verification aircraft, and if there is no accident, it will be no problem to make a first flight within this year." ”

Academician She: "I still can't believe it...... SSTO, I always thought it was a dream, and when this thing flies, we can draw a line with the space community, which can be called the advantage of dreadnoughts over the former dreadnoughts...... How did Seryov manage to keep the empty weight to less than fifty tons? It's something that has to go back and forth to the atmosphere. ”

"The fourth-generation insulation technology is even more advanced than the one on the H2." After Lin Ju finished speaking, he gestured,

"The structure is as simple as possible, from the outermost skin to the inner wall of the fuselage, there are only four layers of material, and the curved surface is processed and formed in one piece, and can you imagine that the outer wall thickness of the outer wall of the aerospace aircraft can even be thinner than that of some passenger aircraft.

We've invested almost a billion dollars in this extra effort, and it's going to cost a lot more man-hours and costs, but it's worth it, and the technology has reduced the weight of the body by at least 20 percent. ”

"Hiss" Everyone already knew what Lin Ju was going to say.

"Therefore, Xinyuan hopes that Tengyun Engineering will receive an additional payment of no less than 3 billion yuan to support the cost of manufacturing the first prototype and technology upgrade......"

The big guy finally couldn't help it: "Xiaolin, although the Tengyun Project is of great significance, this capital demand is inevitably too terrifying. ”

Lin Ju: "If it develops step by step, it will cost more money to complete it in ten or even twenty years, and we are saving future expenses." ”

"But how do I feel that there will be all kinds of places to spend money in the future?"

“……”

Lin Ju forcibly suppressed his urge to nod, spending money must be spent, how can you progress without spending money.

But the big guy didn't say anything more, he didn't call the shots for such a big thing, but he was definitely going to be scolded again, every time the space agency put forward an opinion this year, it was asking for an additional budget, which was envied and dissatisfied by various departments.

He decided to put a little pressure on Kobayashi:

"There's no arrangement for the evening, right? Why don't you come and sit at my house, I have a nephew who has always admired you and wants to meet idols......"

"This nephew, is he male or female?" Lin Ju interrupted directly.

"What's the difference between being male and female? Last time during the Spring Festival, my family said that you would come over for dinner, but they didn't come, but this time you are not allowed to leave. ”

“……”

Lin Ju didn't plan to boldly say the crazy idea of planning to live with the robot, so he nodded and agreed.

……

"The ISS organized a meeting on the expansion plan of the International Space Station and the construction of a new functional module, and Montar and Yuri flew to Paris to discuss."

On 6 April, representatives of the ISS member states sat together in Paris.

There is no way, the pictures of the lives of the five astronauts in the Advance have been spread everywhere, causing a huge public repercussion.

One of the most impactful and widely circulated on TikTok is a "challenge" completed with astronaut Tang Hubing.

He was pushed by two other astronauts from the bottom of one spoke module, curled his legs without touching the bulkhead, and flew directly past the central node module to the bottom of the opposite spoke module, a total distance of just 100 meters, and the whole process was very extreme without skewing into anything.

A video camera was fixed to his clothes, which faithfully recorded the whole process of the 100-meter unpowered floating forward, showing the world the vastness of the interior of the Advance space station in the most unpretentious way.

100 meters, on Earth Bolt only takes 9.58 seconds to run from one end to the other, but from Gagarin to space, it took more than half a century for mankind to create a connected 100-meter living space.

If it weren't for the fear of not being able to stop and hit his head, Tang Hubing could have used the advantage of low gravity to break a new 100-meter record at a speed that even Bolt couldn't do, but that would be too dangerous for the ground to allow.

The impact of this video on the space community is beyond imagination, and it directly stimulates the member states to be prepared to climb a few more steps.

Montar took advantage of the situation to directly release the plan to expand the six cabins, plus the truss to increase the mass by 230 tons, and Lucia released a big move: the HGD rigid rotating gravity module.

Not a behemoth like the Enfront space station, of course, but a smaller, miniature centrifugal module.

With a rotation diameter of only 40 meters, it is much smaller than the Advance's 120 meters, and there are only two living compartments, with an overall weight of less than 30 tons.

But the gravity generated by this little thing is even greater than that of the Advance, which only produces 0.28G gravity, while this Miling centrifugal cabin can produce 0.5G gravity, at the cost of a speed much higher than the two revolutions per minute of the Advance, reaching five revolutions per minute.

Not only is the diameter smaller, but the angular velocity is also greater, exceeding what scientists previously thought was the maximum speed threshold of two revolutions per minute.

The small diameter means that the gravity of the human body from top to bottom in the upright state is unevenly distributed, and the angular velocity will make the brain appear dizzy, nausea, disorientation and other uncomfortable symptoms, and even coma in severe cases.

Of course, the proposer of the plan knew this, so the two centrifugal modules were not intended for the astronauts at all: they were sleeping modules.

Lying down to receive centrifugal force naturally does not have the problem of uneven gravity bearing, and the feeling of dizziness can be greatly reduced when you can't see the reference object when you fall asleep.

The idea of the designers is to let the astronauts get in and accept 0.5G gravity when sleeping, and sleep for 8 hours can play a role in exercising without gravity for two to three hours, so that the working hours during the day can be extended and the health state can be improved, and there is no need to exercise hard.

But the most important thing is that it is very cheap, and the entire module is designed to cost between $1.5 billion and $2 billion, which is a fraction of the technical requirements compared to building a huge centrifugal space station.
