It will still take ten years to complete the actual spacecraft of the astronauts selected for their turn, which is enough time for them to accumulate all the experience.

Huge and complex spacecraft cannot be manufactured like an industrial production line, and it is destined to be slowly crafted by water grinding and even manual operation, even so, the scrap rate of accessories is still surprisingly high.

"No. 2, check the driving system, compare the parameters, I need to be able to connect to the manual at any time."

"Comparison has been completed", you really have to do it manually? Didn't Engineer Chen say that the take-off process was automatically preset by the program? ”

"Just in case",

Rather than putting his life in the hands of others, it is better to believe in himself, and Lin Mo firmly believes in this principle.

"Alright! Everyone starts to take their places, get ready, breathe in one minute, exhale ~~~ inhale ~~~~ exhale ~~~ inhale ~~~"

The mentality before take-off is particularly important, check and check, carefully and carefully, and be more prepared before entering outer space, the more you will be sure, as a prospective astronaut, the calmer your mind at this time, the more you can find the problem.

Even the slightest risk can cause the astronaut to be sacrificed, and before the ignition, the astronaut has a veto to abort the ignition process.

No one can joke with human lives.

This breathing method is a small skill that Lin Mo passed on to others, and I am afraid that no one can master the trick of relaxation and calm down better than a warrior.

After calming down, everyone started to check all the systems and functional modules again, and it was not until just before takeoff that the clock stopped checking and waited for the launch.

With an ignition, the simulator emits a huge noise and vibration, and hundreds of sound effect units of various powers simulate completely realistic sound effects, and the strong vibration is just like the real thing.

The front of the cabin can see the picture on the large LCD screen array outside the cabin, and with a violent tremor, the launch frame quickly disappears from the screen, filling the entire screen, only a large area of blue sky.

The simulated footage captured by the tail camera after the feedback is to see the strong impetus brought by the flames and smoke ejected by the launch vehicle and the strap-on auxiliary rocket, and after sending Space Jun into the sky, the farther away the ground is, and the objects on the ground are getting smaller and smaller.

The gravitational pull of the earth is always unwilling to let any object easily get out of its gravitational circle, fighter jets can easily rise into the sky and fly freely, but it does not mean that it can get out of the atmosphere, which is not infinitely flying upwards can be done, which requires strong and powerless power.

Lin Mo and the others had already felt the overload transmitted from the spacesuit, which was completely different from the overload encountered by a fighter pilot, and the powerful and violent pressure covered almost every part of their body, not even a single hair, let alone a finger.

The seats in the cockpit are completely embedded in the astronauts, which is very comfortable and soft, which can further counteract the overload force and allow the astronauts to have enough physical strength to go into outer space.

The amount of g during overload training is higher than the actual situation, which allows for greater overload tolerance, and redundancy is necessary for the mysterious outer space environment.

If it were an ordinary civilian, I am afraid that I would not be able to hold out for even a minute.

It is not easy to eat in space, and those who are selected as astronauts will have to continue to undergo more intensive training in order to truly adapt to space flight.

In the process of getting rid of the shackles of the earth, under the action of the earth's gravity, it does not fly away from the earth in a straight line, but flies in a parabolic line, with a maximum orbital velocity of 7.9 kilometers per second (equivalent to 23 times the speed of sound), also known as the first cosmic velocity.

Such a strong propulsion force can enable the spacecraft to gradually approach such a first cosmic velocity, and truly drag away from the earth's gravitational range and into outer space.

The speed of the spacecraft will be faster and faster, through multi-stage ignition and fire, and gradually reach the first cosmic velocity, but it will not be achieved all at once, in addition to taking into account the bearing capacity of astronauts and equipment, because in the near-Earth atmosphere, including the ionosphere, due to the "thermal barrier" effect, when the speed of sound exceeds 6 times, the accumulated wēn degree at the top of the aircraft will exceed 1480 degrees Celsius, and even exceed the wēn degree of ionosphere.

If it forcibly reaches a speed of more than 10 times the speed of sound below the ionosphere, I am afraid that it will turn into fly ash at the first time, no matter what kind of high-resistance wēn material will not work, and the wēn degree generated by this speed can even burn up the star, let alone human spacecraft.

And the distance at which the launch vehicle carrying the spacecraft really enters the high-speed stage is between 500 km and 1,000 km above the Earth's surface in the fugitive layer.

Conventional surface-to-air missiles and air-to-air missiles or something, compared with the space shuttle launch, it is simply weak, there is no fǎer comparison at all, that is, the strategic-level intercontinental missiles can still fight, and the others can't even catch up at all.

This powerful speed and peak overload pressure is for:

For astronauts, it's definitely a big burden.

Since the air is extremely thin and beyond the reach of the Earth's Centric Whip, it is easier for spacecraft to reach amazing high speeds.

As for the outer space environment in a weightless environment, there is no gravity, no resistance, and no friction, even a fart is supersonic speed, and if you throw something out, the range is definitely farther than a missile, and even a civilian can destroy any outer space creation of human beings with his bare hands.

Satellites, space stations, space shuttles, and aerospace fighters have all been thrown down with bricks.

In this particular environment, speed has become the first fatal factor. After 10 minutes, there was a strong shock as if it was about to disintegrate, and then it suddenly lightened, and the sky that appeared on the screen changed from light blue to sky blue, sky blue to ink blue, and the endless starry sky with black sè faintly appeared at the far end.

"Now start preparing to enter the synchronous orbit, and the main engine ignition is complete!" Lin Mo's ears kept hearing the voice of the co-pilot Wang Xuejun.

The combination of No. 2 and No. 2 is also the training center wants to see what kind of performance the two best pilots will perform with.

The voices of Lai Yaowu, the old number in charge of navigation, and Meng Yinan, the old number in charge of communications, kept in touch with the ground analog communication nodes, and the voices of dialogue between them continued.

All the booster main rockets and bundle bǎng auxiliary rockets were dragged away in turn, and at this time, the "Penglai" had begun its final sprint, and below it should be the territory of the United States.

Hehe, if it was a real flight, it is estimated that it would have been a long time ago. The multi-land-based super-high-power JI light cannon has been locked, and the same is true for the American spacecraft flying over the territory of China.

In the past few years, the satellites launched by the Americans have been blinded by the Chinese, and even the Russians have done this kind of small tricks, who let you see things that you shouldn't see.

If the space reconnaissance satellite can protect the world, then the old American "Aurora" does not have to come out to play soy sauce, seven times the speed of sound, is it easy for me?

"Hmm, everything is normal, switch to manual cāo." Lin Mo's fine cāo work has been praised by the training center, and his piloting skills are well-deserved NP "unbeatable", even Wang Xuejun has to admit that this, the flying skills of the number, are indeed so "a little higher" than himself.

An experienced veteran driver is even more reliable than a program, after all, the human brain is much stronger than a computer program on a Si board when dealing with unexpected situations.

During the four days, except for the first step into orbit, then close to the space station for docking, and return, the main time was spent on space research and experiments.

The people spent a lot of money and so much effort to send them into space, not for sightseeing, but for space scientific research, under the weightlessness and vacuum environment, as well as the action of cosmic rays, many biological species and substances will undergo wonderful changes.

Some seeds mutate to become stronger and better.

Without the effect of gravity, metal smelting will undergo very wonderful changes, for example, on the earth, there is no fǎ smelted tungsten aluminum alloy, on the earth either the aluminum has been vaporized in advance, or after cooling, it becomes layers of aluminum and tungsten, and there is no fǎ fused together.

In the weightless environment of space, tungsten and aluminum will no longer have weight, tungsten is uniformly dissolved in the aluminum melt, and a sponge-like tungsten aluminum alloy with pores can be obtained, which is a superconductor that can be widely used in high-tech fields such as aerospace and communications.

Like this so-called space smelting, it can achieve zero-contact pollution-free citrus snail suspension smelting, through the electromagnetic coil to create electromagnetic induction to form vortex heating, the fused substances are evenly combined, and high-purity fusions that cannot be done on the earth can be obtained, such as high-performance semiconductor arsenide materials, barium copper oxide superconducting materials, and special alloys such as high-permeability optical glass, high-purity optical fibers, giant single crystals, and high-roundness ball bearings.

It is no wonder that there are rare extraterrestrial metals such as Split ore that will cause a war between the strong in another world, and the Lonsdale stone, which makes humans crazy in this world, all prove that outer space is definitely an unprecedented super treasure.

A coincidence born in a complex and unknown environment may be able to create miracles.

Along with Ren Lou's footing in space, a new discipline of space smelting was also born.

Dragon God, if Lin Mo's gold-based dragon knew this, I don't know if it would go crazy because of this.

And that's just alloy smelting technology, but there are other biological, astronomical and other strategic research.

One step to the sky, perhaps this word is the most appropriate to describe the aerospace industry, mastering advanced space technology, not only the country's scientific and technological strength and industrial base can also reach the sky in one step, and even the people's livelihood can also be one step to the sky.
