The fission and fusion of atoms will bring about a loss of mass, and in this loss of mass, there is a huge amount of energy, Einstein's mass-energy conversion equation, indicating that this is almost inexhaustible energy!

The disaster of World War II was also an era of rapid development of science and technology, the atomic bomb was quickly developed in World War II, and then the nuclear reactor was invented, and human beings can peacefully use nuclear energy to serve the production and life of human beings.

At the same time, nuclear energy is also being used by space agencies, and if nuclear energy can be used in space, it will greatly increase the source of energy!

The first to be used, of course, was the nuclear battery! Many of the Soviet Union's reconnaissance satellites use nuclear batteries, which provide much more power than solar panels, and at the same time, the durability of nuclear batteries is also very strong.

However, how to use nuclear power on rockets is a problem worth considering, after all, nuclear explosions are simple, and nuclear batteries are simple, but how to directly use nuclear power to propel rockets?

In this regard, the Americans are brainstorming, and they have come up with a simple solution. Using a series of small-yield atomic bombs to explode one after another at the tail of the rocket, the propulsion disc mounted on the back of the rocket can absorb the shock wave generated by the explosion and gain power from it! This is the Orion scheme.

As you can imagine, the process of this thing taking off into the air is like a jellyfish in the ocean, jumping and jumping, and every time an atomic bomb is thrown, the rocket shoots upwards for a certain distance. The process is enough to make people frightened!

During the take-off phase, a small atomic bomb with a yield of 100 tons of TNT is detonated per second, and when the rocket reaches a certain speed and altitude, the detonation rate drops to one per 10 seconds, and because it is already far from the ground, it is a nuclear bomb with a yield of 20,000 tons.

At that time, the Americans had already tested with conventional bombs, which was feasible, but this thing was stillborn in the end, after all, it was too frustrating to directly detonate a nuclear bomb!

So, in the end, they all switched to a nuclear-powered rocket engine scheme similar to that of liquid rockets. The United States designed the NERVA nuclear rocket engine, the fuel is mainly uranium-235 or plutonium-239, the nuclear fission fuel generates heat, heats the working fluid in the combustion chamber to make it eject, generally uses the lowest molecular weight hydrogen as the working fluid to obtain the reaction force to obtain the highest jet velocity.

Why can't you use an ordinary chemical rocket? Because these ordinary rockets can only work for a few hundred seconds, but they consume tons of fuel! If a chemical rocket is used to fly to Mars, the rocket ignites for a few hundred seconds and pushes the spacecraft to accelerate, and the remaining long voyage is a process of continuous flight by inertia, which is quite long!

In this regard, the original giant Saturn 5 is a typical representative. Its first stage is loaded with 2075 tons of liquid oxygen kerosene propellant. Once the engine is ignited, it can "drink" all of these "drinks" in 2 minutes and 34 seconds. However, it was only enough to send 47 tons of payload to the moon. Of the 3500 tons of take-off thrust, a significant part was used to "tow" the rocket itself and more than 2000 tons of fuel. The propulsion efficiency of such rockets is low.

The advantage of using a nuclear reactor to heat the working fluid is that it does not need to carry a very large mass oxidant, but only a relatively very small mass of liquid hydrogen. The specific impulse is very large compared to chemical rockets, and the total velocity can be very high. Moreover, it lasts for a long time.

By 72 years, the NERVA-2 engine designed and completed in the United States reached 5000MW with a continuous thrust of 90 tons. Although the thrust is not large, in outer space, as long as there is thrust, the spacecraft can continue to accelerate!

The American design was stopped only at sketches, and at most prototype experiments were simply carried out. And the Soviet Union, on the other hand, has really developed it, and this is the RD-0410 nuclear rocket engine!

Like the nuclear-powered rockets of the United States, the principle of this engine is to use the fission heat energy generated by the reactor to heat the working medium, that is, the propellant, to a very high temperature, and then spray the high-temperature and high-pressure working medium from the nozzle at high speed, thus generating a huge propulsion.

And the Soviet Union, which has always been at the forefront of space technology, has never given up on the development of such a rocket engine! By now, this engine, which has finally matured, has been installed on the rocket!

At the same time, this engine has been further modified to provide not only thrust, but also electricity! After all, when a spacecraft is flying, it also needs a certain amount of power supply! Especially after entering deep space, the farther away from the sun, the efficiency of solar panels will become lower and lower.

Andrei is not yet the general secretary of the Soviets, but, as his successor, he is now in full charge of the work of the Soviets! Before Putin's arrival, Andrei was reading the document, and now, after communicating with Putin, Andrei said: "I have been in the Kremlin for the past few months, and now it is time to go out for a walk." We wanted to go to the launch site to see our rocket launch. ”

In the past few months, Andrei has not gone out, of course, there are other concerns, how serious is the infiltration of that secret Freemasonry into the Soviets? Although Andrei was not afraid of retaliation from any force, he knew that his personal safety was now related to the future of the entire Soviet, so he had to be careful. If you go out casually and someone shoots you out, that's stupid.

And now, a few months is enough time to clean up those conspirators, and at this time, Andrei should also show up to the public, and besides, Andrei really wants to go and see it! Moreover, having become the successor of the General Secretary, Andrei came into contact with more secrets, which concern not only the Soviets, but even the entire human race.

"Marshal Andrei, Varisi is a very competent captain of the guard, he can protect you well, and at the same time, our KGB department will do our best to ensure your safety in travel." Putin said.

Varisi, the captain of Andrei's guard before Putin became Andrei's henchman, is also from the Far Eastern Military District. Valisi's faithfulness is completely reliable.

"Well, the plane will also be inspected." André says: "At the same time, have a backup plan. ”

The last time Andrei returned, the supersonic business airliner was tampered with, and then, after Putin took over the position of chairman of the KGB, he immediately launched an investigation and found out two or three people who served the Freemasons. Boris alone, he didn't have so much energy at all, and he stretched out his hand to Andrei's side, and at the same time, on the Soviet aircraft carrier, a traitor was also cleared, and it was this traitor who leaked Andrei's whereabouts.
