NASA:s Kepler-telescope is near end of the fuel, and it can be pointed to some specific solar system for collecting specific data from the specific exoplanet system

NASA:s Kepler mission is coming near its end, because fuel of the telescope is running low, and this means, that this telescope cannot be turned to the targets anymore. Kepler has been found new exoplanets, and it has given information, that maybe there is a habitable planet somewhere in the Universe.

Some people think, that maybe this telescope can be pointed at some point in the universe, where are known exoplanets. This system could be Gliese-581, or some other system, what can be observed from Earth, and this telescope can collect the information of this particular system. Maybe it should be Alpha Centauri, where we're at least founded exoplanets.

But this is only speculation. Kepler telescope has been used to demonstrate low-cost space telescope technology, and it has given very much for science and engineering, and the data what this telescope have been collected, would be analyzed years after its mission have been ended. And this information would be used to selecting targets for James Webb and other very powerful telescopes, what operates outside Pluto trajectory.

James Webb-telescope would represent the brand new design for space telescopes. This telescope has the table, where the telescope optical system stands. This structure allows turn telescope the way, that the guidance rockets would not need use every time when this telescope selects the target. And if those telescopes would send far enough from Earth, the temperature would be very low, what allows use also infrared radiation for making observations for other solar systems.

MIT's tractor beam can make the new types of SASER systems possible

"This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things. That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries. "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th
