ESA's Hera mission tests new radar technology.

The radar images from the asteroid's internal are interesting things. The radar systems used in the Hera mission are a flexible tool. It can also used to make mineral maps and uncover underground structures. This system is suitable for asteroid missions. And also for civil and military operations on Earth.

The Hera probe has a very small radar, that size is 10 cm. These kinds of miniature radars can be pathfinders for next-generation miniature radar technology.

Engineers can install small-size radars in satellites, aircraft, and drones. It's possible that miniature radars can be installed on ground vehicles like Jeeps, and they can cooperate with optical sensors. Those radars also can search for underground objects like archeological objects, dug metal things, and mines.

"Due to launch in 2024, Hera will travel to the Didymos pair of near-Earth asteroids to test planetary defense, find out more about asteroids, and demonstrate novel technologies. Hera will carry two CubeSats that will get up close and personal with the asteroids.

"This 10-cm box will make history as the smallest radar instrument to be flown in space – and the very first radar to probe the interior of an asteroid. Its target? The Dimorphos asteroid, which on the night of September 26, 2022, had its orbit diverted and a vast 10,000 km plume sent out into space by collision with NASA’s DART mission.

VLF and ELF radars can search submarines from deep sea. The same systems can also map deep underwater structures. Those radars can be used to map Asteroid Ceres' internal structures.

And maybe those radars can someday see Jupiter's Europa moon's ocean bottom. Radio spectroscopy allows the radar to see molecule structures from deep underground objects.

Maybe in the future radars can observe our blog sales because radio waves are jumping out from iron of hemoglobin. And if radar is enough that system can see even a single blood cell. There is a need for a test bed for those highly effective miniature radars.

That is why Hera is an important tool for researching radar technology. The Hera uses miniature radar to make radar images about the asteroid's internal structure. And that means researchers can install similar systems in drones and aircraft. There is a possibility that those miniature radars can be installed in one entirety.

And that allows the system to act like a compound eye, where miniature radars can replace optical sensors. That kind of radar combination can increase the resistance against jamming. In that system, each segment can act as independent radar making it possible to create new multi-band radar systems. That kind of radar also can act as a radio weapon, that aims plus and minus electricity into a target that could overheat it.

The AI-based PCs will replace current PCs quite soon. A Lenovo director says.

The AI-based PCs will replace current PCs quite soon. A Lenovo director says. Lenovo plans to replace current PCs by using new AI-based systems. The AI-based PC is the tool that makes computing more powerful, more effective, and safer than ever before. The Kernel-based AI that guards computers and identifies the users are tools that are required at this time of modern computing. The problem with this type of advantage is that if those AI-based system's servers are in China, makes the PC an ultimate control tool. Another thing is that the host who controls servers can use data collected from the users to create military AI applications. Computer games help to create AI that can respond to all types of actions. And AI also can create things like hypersonic lifting bodies and command systems for military tools. Also, AI can create new types of dual-use systems that control drone swarms in marketing situations for making dragon images in the skies. But the same systems can contro

Quantum computers and ultra-fast photonic microchips can danger even the most secure communication.

"Quantum computers could pose a major security risk to current communication systems in 12-15 years with their exponentially greater speed and code-breaking ability. (ScitechDaily, Today’s Most-Secure Communications Threatened by Future Quantum Computers) Quantum computers can break entire binary cryptography. And that makes all communication unsecured. That is one of the greatest threats in quantum computing. And this brings the arms race to the quantum age. The quantum computer can create codes that any binary computer can break. But the quantum computer can also break old-fashioned codes. And that makes it an ultimate weapon and sabotage tool. Quantum computers can change the measurements of the ammunition in factories by changing the system calibration. Or it can delete databases from the opponent's computer systems. This thing can delete all SIM cards from mobile telephones. In peacetime, the hackers that operate using quantum systems can steal the names of the counter-

The new 3D printers are coin-size systems.

"The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation. Credit: Sampson Wilcox, RLE" (Scitech, Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket) Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems. There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that
