ESA (European Space Administration) tries to find out, what is the reason for the skull-looking structure on the comet. 

The ESA comet lander has been chosen to land near the eerie area on the comet. The "Skull-top Ridge" is the area, where ESA "Philae" comet lander landed on its target comet. NASA just made the mission, where the comet probe took the sample of the asteroid by using the OSIRIS-REx probe, and the sample is underway to return to Earth. 

The purpose of those missions is to understand better the structures of comets and asteroids, but also to test the artificial intelligence and other things, what is necessary to choose the right asteroids for commercial use. The asteroid belt and asteroids are full of important minerals and metals, that can solve the raw material problems of Earth. If we would produce the raw-materials in space, that kind of process is purely pollution-free. The separation of minerals can be quite easy. 

The separation is done by melting the asteroids or bites of asteroids in the cosmic bola and centrifugal separation. The bites of asteroids would put in the chamber, and they can be melted by using the sunlight by solar power microwave systems. If the system uses straight sunlight the parabolic mirror can target the chamber, but the microwave systems can also be suitable for that thing. Cutting the bites from asteroids can be done by using laser-cutters. Then those separated elements like metals can simply send to Earth and land by using parachutes. 

The asteroid Bennu is the C-type asteroid, which is the most typical asteroid. The high-carbon percentage means that there is a possibility to find the diamonds from that asteroid, but if the other minerals like Manganese are found on those most common asteroids, that thing would make the most fascinating things in economics. But the asteroids are also involved the absolute pure carbon, what has ever touch the air. And that thing is a very interesting detail. 

The thing that makes asteroids like Bennu interesting targets for mining operations is that they are traveling near Earth. So they can be easy to reach, and space could clean in that kind of operation from the dangerous asteroids. And this kind of thing is always interesting. If we think that some asteroids don't have interesting minerals, the astroid, what goes near the sun can involve a large mass of Helium 3, which is important in the fusion tests. So that kind of thing is making asteroids interesting things.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting armor has
