 The James Webb telescope is on its way to L-2 point.

There was a little mistake in my text yesterday. The James Webb Space Telescope is on its way to Sun-Earth Lagrange point L-2, not L-1. The JWST is the new and the most powerful instrument that astronomers ever get in use. And the thing is that this instrument is acting as a pathfinder to other, more powerful telescopes that are sent outside the Jupiter trajectory. 

Maybe someday the NASA and European Space Agencies are accomplishing the TAU mission. TAU (Thousand Astronomical Unit)is the space telescope that will be sent away from the solar system, and that telescope will base similar technology with the JWST. But those things are the future views of deep space missions. The truth is that the JWST can reach outer planets as well as another solar system by using excellent accuracy.

The 6,5 meters infrared telescope of the JWST telescope makes it far more accurate than the "Spitzer" telescope, which mirror is 0,85 meters. Spitzer was a great success and that telescope was deactivated in January 2020. But the 6,5 meters infrared telescope would see more than some 0,85 meters telescope. That means the new era of space research is beginning. 

In the future, the Lagrange points around the Sun. Are useful in many more missions. One of the projects could be sending the laser satellites to those points. Those satellites can observe gravitational waves by using more high accuracy than LIGO ever can use.  Lagrange points or "L"-points gravitation is interacting with objects. The way that they are hovering in those points without the need to use the power. The L-points can benefit in positioning the large-size space stations.

The O'Neill cylinder


And that thing can make them useful in the location of things like "O'Neill" cylinders. The thing is that those artificial worlds must not have similar gravitation with Earth. The "O'Neill cylinders" create gravitation by using rotating movement. 

Sometimes is mentioned that O'Neill cylinders are impossible. The rotating movement would cause centripetal force that rips the station in pieces. The gravitation field of the Earth is so strong. That the speed needed for rotating the station is very high. 

The purpose of gravitation in those systems is to anchor things like vegetable cultures to the surface. Not create similar gravitation with Earth.  But there is possible to put powerful magnets to the center of the cylinder. That magnetic stick pulls the structures of that kind of station in the middle. And the magnetic pulling effect will counteract against centripetal force. The magnets would pull the structures inside. And that keeps the wall of the cylinder in one piece.

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...
