Zhu Lei's Saturn V, the heaviest rocket of mankind in his previous life, was more than 110 meters high and had a take-off weight of more than 3,000 tons, but the weight of the fuel was already nearly 3,000 tons, plus the weight of the rocket itself, the load capacity of this rocket with a take-off weight of more than 3,000 tons in low earth orbit was only more than 100 tons, not to mention the high orbit of the earth and the transportation of materials to the earth.

Therefore, the payload of the aerospace vehicle designed by Zhu Lei and them is actually very amazing.

This time, Zhu Lei, in addition to the manned flight, in fact, the astronauts still have a lot of tasks, because this time there is also a core module of the space station that will follow them to the sky, and they still need to assemble it after the space station reaches the orbit.

Although the space station has been modularized, the space inside the space vehicle is limited, and it is impossible to put the core module of the space station that has been assembled, and they still need to manually assemble it when they get to space.

Since the aerospace vehicle is fully loaded, the runway required for this flight is also relatively long, but fortunately, Zhu Lei has considered this problem some time ago.

And the design of the second-generation aerospace vehicle is now about to be completed, and it will be used in the future, so now the entire runway has been lengthened to a length of six kilometers and widened, such a long runway is enough for the first and second generation aerospace vehicles, as for the follow-up model, there is no longer a long runway, because the follow-up model Zhu Lei estimates that the anti-gravity engine should come out.

Since this time it has brought such a heavy mission, if there are no accidents, the Suzaku 1 space vehicle will stay in space for a week. In addition to the installation of the core module of the space station, they also brought a lot of scientific research equipment and some experimental projects. Of course, many of these experimental projects are not Zhu Lei's own, they are official of the Ming Empire, and some are private companies.

If the launch of space satellites and space manned technology is the main goal of all countries now, then the launch of the space station is something that all countries in the world have never dreamed of, after all, in this world, the space manned technology of all countries has not yet been realized, including the world's superpowers, and strictly speaking, the Ming Empire has not yet realized manned spaceflight, but now it has such technology and is ready to launch immediately.

Now it's different, because the Ming Dynasty has Zhu Lei's existence and other countries, so the Ming Empire is no longer satisfied with manned space technology, but has turned its attention to a larger opportunity, that is, to build a huge space station in space, or that the space city is more appropriate.

However, it is impossible to build such a huge sky city in space, but it requires detailed plans and steps, and now the sky city is still being designed, Zhu Lei estimates that the world will not be designed at all without a year or two, and the time required to manufacture and install the space station will be even longer.

However, the plan must be step-by-step, before building Sky City, it is necessary to have a place to settle in space, and you can't go back and forth between the earth and space every day when building Sky City! Although the cost of aerospace vehicles is much less than that of various rockets in the past, it cannot afford such waste.

What's more, this space city will definitely be assembled in space in the future, and the personnel needed are not one or two, there must be a place to rest!

Therefore, this space station is actually a temporary space station built in advance, which can be used for various scientific research and space exploration before the construction of the space city is completed.

When the construction of the Space City begins, it can even be used as a temporary rest point. Although this is only a temporary space station, but in fact, this space station is not small compared with the space stations of various countries in the previous life, and even more huge than the space station jointly built by European and American countries in the previous life.

However, the main thing about this space station is to be used as a resting place for personnel during the construction of the space city in the future, so the most important thing is to work personnel security.

Because if once the construction of the space city starts during the period of time, an average of hundreds of people will live in it every day, which is a huge challenge for this temporary space station.

And now the design plan of the space city has not come out, but the preliminary plan has now come out, and it can even be said that it has been determined. The space station will have a mass of at least 50,000 tons and can provide tens of thousands of people to work and rest on it at the same time, and the structure of the space city will adopt a ring structure, because the current technology on Earth cannot create artificial gravity equipment.

And Zhu Lei's plane mall is not selling this kind of technology now, he asked Xiao Lori, but Xiao Lori told him that this kind of technology is impossible to appear in the primary civilization, even if there is such a technology, it can be made with the technology of the primary civilization.

So in the end, he had to figure out his own way, and after many experts said that there was really no way but to use rotating gravity, which was the best way in the current situation.

And the main frame of the entire space station is also made of high-strength alloys made by Zhu Lei's factory, after all, he has not heard of any manufacturer producing special metals that can surpass these special steels produced by him so far! What's more, during this time, the metallurgical laboratory in his fiefdom was not built for nothing.

According to the ideas of Zhu Lei's previous formula data in his factory, the staff of the laboratory have successfully formulated several new alloy material formulas, and most of the alloy materials smelted according to these formulas have reached a strength of more than 120.

The most outrageous material has reached an outrageous strength of two hundred and eleven, but although the formula of this material has come out, smelting is very troublesome, and the cost is very high, even Zhu Lei is a little unbearable.

And with Zhu Lei's current smelting equipment in the factory, there is no recipe for smelting, because the melting point of this formula is as high as more than 6,000 degrees, and the maximum temperature of these smelting equipment in Zhu Lei's factory is less than 4,000 degrees, so it can only be produced in the laboratory at present, and it cannot be produced on a large scale at all, but the smelting equipment for this new formula has now begun to be designed, but the progress is very slow, but these materials can be smelted in the laboratory state. Zhu Lei believes that the smelting equipment of these materials can also be designed, but there is no good way to do it at present.
