The moonbase plays a big role in the solar system colonization.

Moonbase is the thing that might not look so impressive as Mars or Jupiter bases. But in moonbase, the researchers can find out how to make structures in space conditions. The moonbase is the perfect place for making social and other types of tests for long-term flights. If something goes wrong the mission must abort immediately. There is possible to test life-support and other systems.

Moon station is also possible to use for testing systems like computers, independent operating robots, and AI. And other things that will be trusted and easy to operate. If something goes wrong on the Moon. that thing is far easier to fix than if something goes wrong on Mars.

And on the moon returning to Earth is easier than from Mars or the asteroid belt. The moonbase is also offering a safe place for loading and starting the nuclear reactors for nuclear-powered rockets. When some nuclear-powered NERVA or ion rocket starts near-Earth. And if something goes wrong. There is the possibility that radioactive debris will fall to the Earth.

So if the starting of those engines will happen at the Moon orbiter the radioactive debris will fall to the ground. The moon is also offering a shield against the EMP-pulses that are forming if the Orion-type of system where the small nuclear bombs will push the craft to the outer solar system. The ion rockets can also cause problems for satellites if the high-energetic ions will impact them.

The thing is that electrostatic and microwave-based systems where the propellant is vaporized by using microwaves and them shoot back by using magnetic accelerators are one of the most capable systems. The ion engine requires vaporized material like iron steam but also other ions would be useful.

The problem is how to vaporize the iron or silicone? One version is to use a hybrid system where the material is vaporized by using microwaves. And then it will ionize. Then the system will drive those ions backward by using the magnetic track.

Things like water jet rocket engines are rocket engines. Which are using water or hydrogen as the propellant. The idea of those systems is to replace nuclear reactor what is used in NERVA engines by using something that is not so radioactive. That thing makes the microwave engine a useful tool.

Liquid hydrogen or water will pump into the nozzle. And microwaves are vaporizing it. The full benefit of those systems will get if the liquid gas has a low vaporizing point. The microwaves can use to expand the propellant as well fire or nuclear engines are making. The moonbase is ideal for testing that kind of system.

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...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines. The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
