NASA done the farthest-ever laser communication, or laser data transmission between Earth and Psyche probe.

Laser data transmission test over ten million miles. That is over about 16 million kilometers. The laser communication between probes and Earth is a promising communication tool.

Laser communication systems are less sensitive to radio disturbances than radios. That's why the military is interested in laser communication.

The high-power laser communication system can have two lasers that operate at different frequencies. The system sends data using TCT/IP protocol like the Internet. Data packages will be sent by using different wavelengths.

The ability to use two lasers increases the transmission speed. Every data package is marked with the serial number. The receiver collects them together using those serial numbers to connect data into one entirety.

Another thing that makes lasers good tools is that the probe can connect missions of those systems. The laser systems can be used to vaporize the surfaces of the asteroids. And that helps to make the spectroscopy research about the surface of the asteroids. But the same laser system can also communicate with the control center. The key element is that lasers can be used for multiple missions.

They can measure altitudes, and vaporize an asteroid's surface material for spectroscopic analyses and the same system can communicate with the control station. The high-power communication lasers can also protect the spacecraft against the small icy particles. If the laser system shoots the ice bite it vaporizes its shell and that changes its direction. And that can deny the impact.

"NASA’s DSOC (Deep Space Optical Communications) experiment, aboard the Psyche spacecraft, has successfully demonstrated the farthest-ever optical communication using a near-infrared laser from 10 million miles away. This milestone, managed by NASA’s Jet Propulsion Laboratory, marks a significant advancement in space communication technology, promising higher data transmission rates for future deep space missions.

The lasers can increase the power of ion thrusters.

In some visions, high-power lasers can be used as a power source for the thruster. The laser ray vaporizes material like some gas or metal powder that expands and the expanding material pushes spacecraft forward. So laser can be used to vaporize material like metals for the ion engines. And in that case, the same laser can keep communication contact with Earth.

The laser engines base an idea. The rocket uses a laser ray for making expansion in propellant. That pushes craft forward. And that kind of laser-ion engine's propellant can be methane ice or some metal like mercury. The system can drive metal vapor through the ion engine. But the laser engine can also use non-magnetic materials that it vaporizes. And if the system requires more power it can ionize that material. Then it drives that material through the magnetic acceleration lines.

High-power lasers can also clean things like Earth orbiter py pushing debris into the Earth's atmosphere. The high-orbiter or geostationary satellites. The high-power communication lasers also can be used as laser weapons. So the difference between communication and laser weapons is not as big as we hope. The geostationary satellites that have high-power lasers can clean debris from orbiting trajectories. But the same systems can also destroy satellites.

Use virtual "perpetual motion machines" and seawater as energy sources.

Use virtual "perpetual motion machines" and seawater as energy sources. The Archimedean screw can offer almost endless energy sources. "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics. The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics. The real perpetual motion machines don't use outside energy. And that's why they are not possible.

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger. The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth. It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons. It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field. An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru
