Lasers and satellites are the ultimate tools for research.


NASA's GEDI (Global Ecosystem Dynamics Investigation) spaceborne laser is one of the most interesting tools for high-accuracy, complex emission research. The GPS can warn about earthquakes hours before they are visible. But lasers can make that system more effective. The laser reflector's positions, which can be determined with very high accuracy, can be observed by geostationary laser satellites. And that system can offer the same accuracy as lasers. The quantum radar of a radio wave is as thin as an atom or electron. Can replenish the optical system on cloudy days.

GEDI (Global Ecosystem Dynamics Investigation) is one of the new tools that researchers have for studying large-scale, remote ecosystems. The highly accurate laser systems can observe the gas exchange on the top of the leaves. And if the satellite makes the laser beam larger, the system can observe large areas.

"NASA’s space laser, GEDI, has revolutionized our understanding of rainforests, revealing a simpler structure with a peak leaf concentration at 15 meters. These insights could significantly impact our knowledge of biodiversity, species’ adaptation to climate change, and the carbon storage capacity of forests". (ScitechDaily.com/Into the Unknown: NASA’s GEDI Space Laser Provides Answers to Rainforest Canopy Mystery)


"A comprehensive analysis of GPS time-series data suggests a precursory phase of fault slip occurs two hours before large earthquakes. However, the current inability of monitoring tools to detect such slips at the scale of individual earthquakes remains a significant challenge for practical earthquake prediction". (ScitechDaily.com/Early Warning: GPS Data Could Detect Large Earthquakes Hours Before They Happen)

The main purpose of GEDI is to observe and calculate the canopy of the rainforests. The GEDI can use 3D scanning technology to observe the shape and other things about the canopy of the forest. The system can also detect chemicals that travel through trees and search for things like pollution. But GEDI can also detect the pheromones that wood and animals use in communication.

There is a possibility that GEDI can also detect the sounds of rainforests. The system acts like all other laser microphones to detect oscillations caused by resonance. And that tells a lot of things about animals and other species in the rainforests.

The GEDI system is one of the next-generation tools for making observations about landscapes that are far from the human environment. The purpose of GEDI is to study things like complex ecosystems and how species interact with each other by sending chemical signals. The system could analyze those chemical marks in the air.

And modern technology allows for the analysis of complex pheromone molecules. The laser rays, along with high-accuracy telescopes, and plasma spectrometers, give extremely detailed information about the gas and other chemical exchanges in the rainforests. Orbital laser satellites can see the emissions of individual cars. And they can be used in multiple missions.

The GPS can turn cell phones into earthquake detectors. The idea of that system is that those cell phones can be put in certain positions on Earth. By using remote control, the operators can update and observe things using the satellite-based monitoring system.

Laser satellites can be used to find tsunamis. The satellites can see changes in the density of water. And then the laser system can see if there is movement in some kind of denser water area that is not visible from the air or ships.

The laser system can connect with GPS-based earthquake warning systems. In those systems, the GPS that is in large areas measures the changes in the dynamics of the earth's shell. The system detects the location of those GPS systems, and if there are any changes, that satellite system tells it to center. That allows the system to predict earthquakes hours before people see them.

There is only one problem. Those GPS systems require energy, and another thing is that somebody might try to steal the GPS transmitters. The passive system uses laser mirrors that are precisely placed in certain positions by using GPS assistance. The laser satellite can locate those laser reflectors and see how their position changes.

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

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
