Drones have new missions. From Jupiter's moons to a depth of oceans.

"In the Sensing With Independent Micro-Swimmers (SWIM) concept, illustrated here, dozens of small robots would descend through the icy shell of a distant moon via a cryobot – depicted at left – to the ocean below.

The most impressive mission for drones or independently operating miniature submarines will be the search for life from Jupiter's moon Europa. The thing is that also two other large moons, Ganymede and Callisto could have similar oceans under their icy surfaces.

And the third Galilean moon, Io has sulfur volcanoes that are also interesting geological objects. But the main object for that mission could be Europa, the icy moon with icy geysers. The probe can slip the small submarine into those geysers and maybe they can reach the ocean under that icy surface. The done can communicate with the surface unit by using sonars.

"After completing testing, the Robotic Servicing of Geosynchronous Satellites (RSGS) payload resides in the cryogenic thermal vacuum chamber at the U.S. Naval Research Laboratory’s Naval Center for Space Technology in Washington, D.C.

Large-size drone swarms can cover large areas under the icy surface. They can have only a limited number of sensors. But those drones make sensor fusion. And the drone swarm behaves like one bigger platform. This means. Those drones can carry similar sensors. As one large probe or aircraft. But the difference is that those sensors are under different independently operating bodies. And if one of those drones is gone, that doesn't make the failure to the entire mission.

And that nuclear-powered unit will find a strange water world that is interesting even if there are no living organisms. But those small, long-lasting, independently operating drones can also have missions on Earth. The small AI-controlled drones can also operate in icy lakes under the Antarctean and Greenland icy shells. Things like closed caves and underwater water routes can also be places. That those drones can map.

"In this illustration, a NASA space exploration concept called Probe using Radioisotopes for Icy Moons Exploration, or PRIME, is depicted being deployed from a lander on the frozen surface of an ocean world. The nuclear-powered probe, also called a cryobot, glows red in the subsurface ocean while connected via a communications tether to a lander miles above on the icy crust. Wedge-shaped, cellphone-size robots – another concept, called Sensing With Independent Micro-Swimmers, or SWIM – are seen traveling off underwater to conduct science beyond the heat of the probe.

They can collect information about the closed ecosystems. That can be isolated even for thousands of years. But the same systems. That can map and research insects. Also, can collect data from other things. Drones can collect information about underwater systems like submarines. The new radar systems can follow underwater acoustic communication. The same systems can also search for information from the targeted people's discussions.

The radars can search for things like pressure waves from air or water. And they can used to record the things that people say. Water carries sound at a very long distance. And the system that can measure the oscillation of the water surface can break the privacy of people, who are not careful. The submarine that travels in the water lines can eavesdrop on people in their houses and even the army headquarters.

The new innovative robots can act as maintenance missions for spacecraft. They could repair the unmanned satellites and probes if they face problems. The repairing robot is the tool that can make the things like large-size, nuclear-powered drones more effective. They can be sure that the expensive system can fulfill its mission. But similar robots can also fix other underwater drones and structures. The undersea robot can also make it possible to return unmanned systems that return from intelligence or strike missions.

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
