Bright Sword starts with the grenade flat.

Chapter 254 The fifth reward of the system
That's right, Chang Zheng 1 was not supposed to launch until 1970. In fact, the Chang Zheng 1 project was established in 1958, but it happened to coincide with the three-year disaster and the evacuation of Su Tuo.

So this push continued for seven years until it started again in 1965, and then it was successfully launched in 1970. However, now because of Liu Xiu's existence, the stage of launching satellites has been skipped.

Because this broadcasting satellite is really useless. Once it was sent up, it only heard the sound for dozens of days. A satellite without solar power panels is actually a lump in space.

Of course, the reason why Liu Xiu dared to earn money to be an astronaut and dared to try was because he had the confidence. Yes, Liu Xiu's confidence was naturally due to his defeat of Du Gao and sending all the senior officials of Du Gao to After Jianping signed the non-aggression pact, the Savior System, which had been silent for more than ten years, actually got news again and gave Liu Xiu his fifth system reward.

And this time the system reward directly maxed out Liu Xiu's life-saving ability.

That's right, the fifth reward given to Liu Xiu by the system was actually space jumping. That's right, it was the kind of space jumping ability that was similar to that of the famous Flying Thunder God.

The jumping range is exactly the detection range of the enemy and friend maps, which means that within the one light-year radius of the enemy and friend detection maps, Liu Xiu can jump wherever he wants.

It was precisely after having this ability that Liu Xiu dared to try to be an astronaut so confidently and boldly.

After all, with this ability, even if the spaceship Liu Xiu was riding exploded, Liu Xiu didn't have to worry about not being able to escape.

The reason why Liu Xiu wears diapers is naturally because he is afraid that he might not be able to hold it in the air. Although this space flight is the same as Gagarin's, he will circle around the Blue Star and come back, which is 1,100. A little more than a minute and an hour.

Liu Xiu's spacesuit is not like Su Ruo and Mi Ruo's space suits. Instead, after adding a titanium alloy hard layer on the outside, the inner layer is the thermal insulation layer and the airtight layer.

However, current electronic technology, especially integrated circuit technology, has not yet reached the standards for manufacturing starships, so even if Liu Xiu had the drawings, he could not directly manufacture the starship.

First, keep the pressure balanced: make the pressure experienced by astronauts similar to that on the planet. Since the pressure inside the human body is almost equal to the atmospheric pressure on the ground, and the outside pressure is almost zero when astronauts are walking in space, so in order to maintain the pressure balance inside and outside the human body, astronauts must wear spacesuits filled with gas at a certain pressure. .

Before the time travel, Liu Xiu had nothing to do. He downloaded and read the starship drawings. Therefore, after time travel, thanks to the doubling of physical fitness and the skill of thinking explosion, Liu Xiu is now able to completely Draw the drawings of the starship from memory.

In fact, having said that, Liu Xiu originally wanted to directly build Tesla's starship, because it had publicly announced the manufacturing drawings of the starship before.

But Liu Xiu still put on a diaper just in case. After all, this small space capsule was not the later space station, and there was no toilet or anything like that.

Therefore, Liu Xiu had no choice but to copy the Suzhou Dongfang rocket for manned launches.

Generally speaking, if people want to survive in the space environment, the spacesuit must meet five conditions.

Second, radiation protection: blocking strong and harmful radiation such as radiation from the sun and cosmic rays. After all, a large solar flare can produce a radiation dose of up to thousands of rads. People exposed to such intense radiation can only survive for a week at most. Therefore, it is important for aerospace industry to prevent solar radiation and cosmic rays from harming astronauts. The primary function of the service.

Third, anti-freeze and high temperature resistance: adapt to the complex and changing environmental temperatures in space or extraterrestrial planets. Whether it is space or an extraterrestrial planet, the environment is harsh and the temperature difference between day and night varies by hundreds of degrees Celsius. For example, on the moon, the temperature reaches over 100 degrees Celsius during the day, and drops to nearly 200 degrees below zero at night.

Fourth, the life support system: provides oxygen and removes waste gases such as carbon dioxide, handles astronauts’ excrement, and maintains ventilation and heat dissipation. In addition, it is also equipped with equipment such as flight systems and electronic communication systems to protect astronauts and have a complete life system. Fifth, impact protection: Considering the existence of space junk and micrometeorites in the universe, the impact resistance function of the spacesuit is also necessary. If the quality of the spacesuit is not up to standard and is punctured, the pressure inside the spacesuit will drop sharply in less than a minute, and the oxygen needed to maintain life will be exhausted. Needless to say, the astronauts will soon have to play.

Therefore, in Liu Xiu's view, protection from impact is the most important thing, so it is best to add a layer of titanium alloy bulletproof to the outermost layer of the space suit.

Of course, it only protects against small meteorites below one millimeter, so the titanium alloy shell naturally does not need to be as thick as a bulletproof armor.

And Liu Xiu's space suit, which looks like an Iron Man suit, naturally looks much better than those bloated space suits.

Of course, Liu Xiu did not do anything during the more than an hour in space. Instead, he took a camera and started taking pictures of the entire Blue Star to provide evidence for his publicity after his return and landing.

Unlike Gagarin's spacecraft, which was almost fully automatic, the return capsule Liu Xiu took was just the opposite. It was basically fully manual and was also equipped with a small landing recoil rocket to slow down the landing speed of the return capsule.

Because of Liu Xiu's manual control, the landing location was basically not much different from the expected location.

After Liu Xiu landed, a reporter immediately started filming with a camera, and then went to the TV station to broadcast it after returning.

That's right, as early as 1958, Jiaping had already built a TV station, and also built a factory that could produce black and white TVs. The TVs it produced were called Jiping TV.

As Liu Xiu planned to store grain in advance, the impact of the three-year disaster was not great. On the contrary, because the water diversion project stimulated a large number of factories and enterprises, televisions and TV stations naturally developed vigorously. .

There is no need to worry about livelihood, so the infotainment industry is naturally allowed to expand.

Nowadays, although we cannot say that there is one TV set in every household, at least there is one TV set in every village.

No, Liu Xiu bought a black and white TV set for the courtyard.

Of course, the gap between this TV penetration rate and the 90% in Mi'ao is still very large. It is not even comparable to the 50% in Su'ao. After all, only one TV can be owned in one village. This means that the penetration rate of television is only about 5%.

However, Liu Xiu believes that as the economic situation improves, the popularity of TV will continue to increase.

Naturally, the reporters from the TV station came with cameras to publicize the news of Liu Xiu Aerospace's success.

So that the common people know that Duojia is not that bad compared with Suuo and Mizuo. What Suuo and Mizuo can do, Duojia can also do.
