In the fifties, mankind tasted the power of nuclear energy for the first time, and began to develop and apply a large number of nuclear energy with great interest

Of course, there are also unreliable ones such as nuclear-powered cruise missiles and nuclear-powered bombers. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Therefore, the use of nuclear-powered spacecraft to realize the dream of human beings to fly into the sky was naturally among the considerations of scientists from all over the world at that time!

The United States took the lead in proposing the Orion program, and Taylor, an American nuclear bomb miniaturization expert, believes that if a huge spaceship is blown up into the sky with the thrust generated by the explosion of a nuclear bomb, it seems to be a very good note, and the principle is that the earthen plane is a concept that puts explosive packs under the chair to blow people into the sky.

Of course, a nuclear bomb is not enough, after the spacecraft is blown up, it will run out of power after flying for a period of time, and then it will be pulled back to Earth by gravity. So you have to keep detonating the miniaturized nuclear bomb behind the butt and keep generating thrust until it propels the ship into outer space.

Although this idea is crazy, it is theoretically feasible, and the technical difficulty is even lower than that of building a nuclear submarine.

But with the adoption of the Treaty Banning Nuclear Tests in the Atmosphere and in Outer Space, the world could no longer conduct nuclear tests, and the Orion program's idea of bombing a spacecraft into space with a nuclear bomb was ruthlessly terminated.

In fact, this is the only way for mankind to send tens of thousands of tons of space vehicles into space under limited technical conditions!

After all, as long as the power of the nuclear bomb is sufficient, it is not impossible to send a spaceship the size of an aircraft carrier into space. It's just that the radiation contamination produced after the nuclear explosion is also a problem that scientists have to consider, which is also the fundamental reason why Orion has never been able to really put into production, after all, human beings cannot bear the pain caused by nuclear pollution.

The Orion project was stillborn, but humanity's dream of flying out of Earth has not ended. In the seventies, the British Interstellar Society proposed an even more spectacular 'Daedalus Project', an unmanned starship similar in shape to the starship in the movie Avatar or The Martian. It is also the use of nuclear power to propel large spacecraft weighing tens of thousands of tons to carry out interstellar flights.

It's a pity that this is just the crazy idea of a few British scientists, and many technologies were simply not possible at that time, so they remained on paper.

The Orion project is much more realistic, because it is simple and crude, and the Americans have even done many simulation tests with ordinary explosives, and they have indeed blown up the model into the sky, which has also proved the feasibility of this plan.

Nuclear power is not good, human beings have also made achievements in conventional high-thrust rockets, in the moon landing competition that year, the Soviet Union made a super giant N1 rocket, and the United States took out the Saturn V high-thrust rocket.

Because the Soviet Union did not have a high-thrust engine, the N1 rocket used 30 engines to spell out a large rocket of five stages to make up for the lack of thrust. However, it was clearly a bad idea, as the number of engines and the instability of the structure led to the failure of all four test launches, the longest of which lasted only 100 seconds, and the Soviet Union's lunar landing program was completely ruined.

In contrast, all 13 successful launches of the U.S. Saturn V made it possible for Americans to land on the moon.

It is a pity that the United States did not make persistent efforts on high-thrust rockets, but turned its head to engage in a space shuttle that takes into account military use, and the final result is self-evident, the space shuttle project failed, and the Saturn V rocket also stopped further research and development, and a technological fault line appeared, which is equivalent to the United States' space strategy completely taking the wrong path.

After the Cold War, human aviation seems to have entered a cooling-off period, except that the flower growers continue to develop their own space science and technology, from unmanned to manned spaceflight, and finally to the space station and the moon landing program. The United States and Europe have no exciting space programs other than the International Space Station and a number of probes launched.

The development of large spacecraft in low-Earth orbit is beginning to falter, and the International Space Station, which is only a few hundred tons, took nearly 20 years to assemble.

Especially with the deterioration of the U.S. economy, the global military spending, and the growing class of the poor at home, NASA's annual funding has become completely supported by the stepmother compared with the Cold War period.

In the end, NASA had to start going wild and opening up private companies to enter the space field.

Soon Silicon Valley Iron Man Elon Musk took over the baton from NASA, and he launched the Mars immigration plan, which is ready to use the 'Dragon spacecraft' to send one million earthlings to Mars to colonize within 50 years, and the ticket price per ship can eventually be reduced to $100,000. And if NASA uses a spaceship to send a person to Mars, the ticket price will be at least $10 billion, and this kind of high-tech really needs to be similar to the genius of Iron Man to promote.

$100,000 may be expensive for the average person, but don't worry, human resources are extremely valuable in the early days of Martian colonization. As long as you dare to take the risk of taking a dragon spaceship to Mars, even if it is just digging soil and growing vegetables on Mars, two or three months of salary may be enough for you to return to your capital! Therefore, young people today should exercise more and lay a good foundation for going to Mars to make a fortune in the future!

Musk sent the Dragon spacecraft into space with a super large rocket, which is 122 meters high and 12.2 meters wide, and can carry 100 people at a time. The first unmanned flight to Mars is expected in 2018, followed by several more unmanned flight tests.

In 2025, the first manned flight to Mars will be carried out, and the first earthlings to land on Mars will say like Armstrong after making their first footprints on Mars, which is a big step for mankind......

Not to mention, Musk's plan is considered feasible, and the goods have really raised money, if he can really carry out the first launch of a super-large rocket in 2018, as long as it succeeds once, it really proves that this crazy immigration plan can be realized, then the follow-up venture capital will continue to be injected, and the dream of human immigration to Mars is estimated to be realized under the planning of Iron Man in Silicon Valley.

Of course, there are still many people who question that Musk wants to cheat money through the super rocket program, but Chen Xu confirmed at that time that this Musk really wanted to do this, and his scientific research team was already building the Dragon spacecraft, but it was a pity that he didn't live until the Dragon spacecraft flew into the sky and returned to the late seventies, and it would take almost forty years to see it again!

If Chen Xu wants to engage in the space program independently, he will definitely not engage in the space shuttle!

Flying astronauts out of the atmosphere on a bulky, brittle space shuttle filled with explosive fuel is a disaster in itself.

Although there will be the problem of nuclear contamination, China and the United States will be able to make quite clean nuclear bombs in the future, and the radiation will dissipate in a short time after the explosion, causing less pollution than ordinary rockets.

After all, the fuel used in modern rockets is highly toxic, and no one will believe that it burns without polluting the environment!

In addition, there is another way to go, in the later generations NASA restarted the research and development of the space shuttle, but this time they learned a lesson, no longer thinking about the space shuttle to catch satellites and other military purposes, but purely transport personnel and materials to the sky, reduce a large number of unnecessary equipment, the streamlined space shuttle is only more than ten meters long, half shorter than the fighter jet.

Being small and light means that it will be fuel-efficient when flying, and it will not necessarily carry fewer people and supplies than the huge first-generation space shuttle.

Although the second-generation space shuttle is very small, it already has a touch of space plane feeling, and if the test flight is successful, it may become a special companion vehicle for the Dragon spacecraft.

Of course, in addition to bombing spacecraft and pocket space shuttles, Chen Xu also has a way to learn from Musk to engage in conventional large rockets, and he also has this technology, because he has the design of Saturn 5 in his head!

After the last Saturn 5 launch in 1973, the Americans loaded this rocket into storage for the space shuttle. It wasn't until Musk's big rocket program was launched thirty years later that NASA took out the drawings of the Saturn 5 and handed it to him as technical support.

For a full thirty years, NASA lost not only time, but also the dream of an entire generation by mistakenly developing the space shuttle!

In fact, with China's current level of science and technology, the ability to play the pocket space shuttle is not enough, and the technical level cannot be reached. At most, Chen Xu can only set up this project department to do project research, and it is still two to say whether he can get it out.

However, Saturn 5 will definitely be able to be made, after all, it is the technology of the 50s in the United States, and it is not very difficult for Chen Xu to come up with the design drawings to create the real thing.

Don't forget that the flower planter is also a big rocket country, and there are many talents in this area, there are two aerospace bases in Jiuquan and Xichang, and there are as many people as you want to dig!

Playing aerospace, Chen Xu is not ready to do it with the country, the national aerospace is too cautious, and everything is slowly swallowed and killed. Therefore, he wants to start anew and use his own will to forcibly promote the development of the space program.

In Chen Xu's space program, the big bombing spacecraft will be the main direction of attack!

He would first set up a laboratory to collect data with ordinary explosives, and then use a supercomputer to calculate the flight trajectory and design flight control software and automatic control systems for the spacecraft. When all the data is collected, he will start the construction plan, learn from Musk to directly launch the 100,000-ton supership in one step, and then blow it up into space.

It is easy for a 100,000-ton spacecraft to fly into space, but it is basically impossible to land back on Earth, and if it falls back to Earth, it will turn into a large meteorite and burn up and disintegrate in the atmosphere.

So this is the size of an aircraft carrier, and it can only stay in outer space orbit and can act as a space station...... (To be continued.) )
