The nuclear thermal rockets will take humans to Mars in 45 days.

 

The new nuclear thermal rocket concept will make it possible to transport humans to Mars, and back to Earth in 90 days. Nuclear thermal propulsion is not a new idea. In the 1970s' NASA planned for NERVA (Nuclear Energy Rocket Vehicle Application). NERVA rocket engine was the nuclear reactor. That reactor was in the combustion chamber of a quite conventional rocket engine. 

There were some tests for that engine in the Nevada desert in the 1970s'. But then the NERVA system closed. Nuclear thermal propulsion makes it possible to create nuclear-powered Moon and Mars shuttles. Nuclear thermal propulsion makes it possible to create flexible and powerful rocket shuttles. 

There could be two stages for nuclear thermal propulsion. First, the crew and passengers will shoot to the orbiter using a conventional space shuttle. Or they can use the laser-powered craft. Then the crew will transfer to the nuclear rocket. That kind of system can operate anywhere inside the asteroid belt. 

Nuclear thermal engines can revolutionize space missions. Those systems need lightweight powerful nuclear reactors. Those reactors might use plutonium that has a weapon enrichment level. Or some other highly radioactive isotope. 



If nuclear thermal propulsion uses hydrogen as the fuel it will not turn it radioactive. That means the nuclear-powered shuttles can operate from the Earth if that system can deny radioactive waste. If nuclear thermal propulsion can turn safe. It can use to transfer airplane-shaped shuttles even to another planet. And that system can operate from regular airfields. 

The nuclear-powered aircraft can fly for 15 years. And that makes them more. Powerful than we ever imagined. 




Plasma engines can be even more powerful than nuclear thermal propulsion. 


If the aircraft uses plasma mirroring. It can make the low-pressure area in the side where the craft shoots plasma. Those ions are making it possible that the craft can make incredible maneuvers. If there is some kind of low-pressure area on some side of the vehicle. That makes the craft will move to that point. 

The rumors say that the famous "Black Triangle" UFO uses nuclear thermal propulsion along with plasma mirroring. The idea is that the laser rays are making ions around the craft. And then the plasma mirror or magnetic field will push those ions away from the craft. That means the ions can operate for stealth purposes. 

Or they can be much more. The ions can make low-pressure areas in the side where the system shoots them. And that thing makes it possible to create a craft that can make unbelievable maneuvers. 

That makes it possible to create the nuclear-powered interplanetary VTOL (Vertical Take-Off and Landing). Nuclear thermal propulsion can give that kind of system abilities that no other aircraft in the world has.

North Korean nuclear facility Yongbyon Nuclear Scientific Research Center

North Korea makes it uranium in Pyongyang plant, what is placed near the uranium mining area. The purpose of that platform is to enrich the natural uranium for reactor use, and then the nuclear waste can be used to produce nuclear weapons. In this process, the plutonium would be separated from other waste, and then it will be enriched by using the centrifuges, what are similar, what is used in the uranium-enriching process. But is this the real story of the nuclear capacity of North Korea?


Another way to make nuclear bombs is to use the nuclear material, what was stored in the Soviet-built test reactors in Yongbyon Nuclear Scientific Research Center, in the reactors, what was produced in 1960's and late 1970's. There is claimed that those reactors produce the only iodide for cancer medication, but if that state doesn't have uranium mines anywhere, the storage of the nuclear material will be ended soon. If there would not be new nuclear material, that means that somebody must sell the uranium ore for North Korea or it must dig from the ground.


But uranium is the very heavy element, and that mining must be very deep, and there is not much uranium in that ore. So the enriching enough uranium for nuclear reactor needs very large chemical platforms and centrifuges. After that, the material would be sent to the reactor for giving neutron radiation for uranium 238, what should transfer to plutonium, and return it to the centrifuges.


The material what would be brought from the nuclear reactor is very high radioactive, and the special protection is needed. So does the North Korean government technology, what must have for transporting that material to the handling platform? If that state used the plutonium, what was based the material, what is stored in Yongbyon Nuclear Scientific Research Center, there are limits how many nuclear tests that country can make.

The North Korean nuke is not probably very technical, but it might work as very good deterrent

When we are talking about the technology, what is used in the missiles of the North Korea, we must say that the diagrams of those systems are available in all libraries in the west and many Internet-pages. The missile of the North Korea seems like some kind of copy of the Titan missile from the 1950’s. The rocket of the longest range missiles of that country might be liquid fuel systems, but the smaller might use the solid fuel.

The problem with solid fuel rockets is that they need very special chemical industry, and that’s why liquid fuel rocket is more easy to produce. The liquid fuel rockets normally can use any kind of hydrocarbon and oxygenated for the fuel, and that’s why German scientists choose the liquid fuel for V-2 rocket fuel. The solid fuel is more effective in missile technology because that fuel can store inside the missile, and it gives missile shorter reaction time.


There is also the liquid fuel combinations what has the capacity to store inside the rocket, but the problem of those fuels is that they are very corrosive. The nitric acid and hydrazine are the very popular combination of the fuel, what is used in missiles, but the problem is that those components are very poisonous and corrosive.


The main rule is that if the rocket has more than one motor, it will be liquid fuel system. The structure of liquid fuel rocket is more complicated than solid fuel systems, and the problem is that is that. if there is oxygen in the fuel tank, it will cause the explosion.


And the pressure in the motor firing chamber will rise very high, and that is the reason, why liquid fuel rockets must equip with the powerful pump system, what pulls the fuel with a higher pressure that there is in the firing chamber. If the pressure would be less than in the firing chamber will the fire sucked in the tank, and the result might be the explosion. And that was the problem also with many other rockets.

The rocket is not the only part of nuclear weapons. Also, the guidance system is very important part of this very complicated weapon systems. North Korea might use the inertial guidance, where the gyroscope will guide the missile to the target. And that system needs two points for the sharp guidance. The beginning point of the trajectory must determine sharp because that makes the missile the capacity to strike with high accuracy. If the launch point determination is not sharp, that decreases the missiles capacity to strike against hardened targets like missile silos and command bunkers, but if the state uses that weapon for terror r strikes against the civilian targets, it will not need great accuracy.

I don’t know how the North Korea will detonate their nuclear warhead. They probably use the impact, barometric or the time detonators to explode the nuclear warheads. And the problem with that equipment is that I don’t know what kind of security equipment those warheads have.


 But the other problem is, that if some terrorists will get that warhead in their hands, they might build the pollution bomb with that plutonium. They must only explode dynamite in the crushed bite of plutonium, and that will deliver the radioactive material around the area. Or they might able to explode the implosion device if the security is not enough. The problem with those people is, that they will not care about themselves.
