Van Allen belt and the space missions





Van Allen belt and the space missions

The thing, that Explorer I satellite found were the Van Allen radiation belts around the Earth. And that kind of plasma ring is dangerous for the electronics. Even if the Apollo 11 flew across this area, the thing is that the technology of the 1960s was far lasting against the radiation of the plasma ring. The size of modern microchips is so small that the overvoltage causes very easily the short circuit in the small size wires. The computers of the Apollo 11 were made by using separate transistors, and many systems were analog. So that kind of system is less vulnerable in that kind of situation. 

The programs that were used were less complicated than the programs of modern artificial intelligence-based systems. Also, digital communication, where the information is sent in as binary numbers is more vulnerable than the analog communication. This means that the loss of one single byte can be devastating for the communication and that can mean that the computer cannot open the message. 

Van Allen belt has a great effect on the spacecraft because that thing is the belt of the ionized gas around the planet Earth. Van Allen belt is not a unique thing in the solar system, and also other planets have the plasma belts around them. And those plasma belts are the reason for rings of giant planets. 

Plasma belt causes extremely powerful radiation in the spacecraft and that means that the spacecraft would be damaged badly if it would travel in the Van Allen belt, and that thing is one of the most interesting things in space exploration. The thing that the spacecraft, what operates in the radiation zone will need is the electromagnetic system that pushes the ions away from its outer layer. 

The plasma layer is the place, which is one of the most hostile places in the known solar system, and that thing is also offering the power source to the spacecraft, which normally operates with the solar panels. The antenna that collects the electricity would just pull in the plasma-layer, and that thing inducts the electricity to the electric circuits of the satellite or some other spacecraft. 

That thing allows that the diameter of the satellite can be smaller, and the large size solar panels would be unnecessary. This makes satellite a more difficult target for low-orbiter anti-satellite systems. The problem is that the plasma-layer, as well as solar panels, can create too much power, and that causes overloading of the electric circuits of that spacecraft. 

And the thing is that overloading the electric systems is more dangerous in the spacecraft like a satellite than the same phenomenon, what happens on the ground. In normal case, the electric system what faces overload would conduct that electricity to ground. But the thing that the spacecraft must do is do something else with that thing. 

One version of the action, what will remove overloading is the high-power radio-impulses, what can target to plasma layer, because of the plasma can absorb that radio signal, and that doesn't cause danger that some high-flying aircraft will face the EMP-strike. The problem with Van Allen Belt is that the plasma is reacting in a magnetic field. And if the polar of the radio-transmitter, what targets to Van Allen Belt is opposite to plasma, that thing can cause that the plasma would touch the spacecraft, and this can cause the failure of electronics.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

.     The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...
