NASA keeps looking for technosignature of alien intelligence.

SETI keeps going and searches for techno signatures. The AI and new sensors are the tools that researchers want to use in that search that can continue longer than a lifetime. Or the search ends tomorrow. The problem is that nobody knows what they searching for.

Searching techno signatures like Dyson's spheres and artificial pollution is different than trying to make contact with aliens. Technosignatures are passive signals like pollution, city lights, or radiation from power sources.

The extreme version of the techno signatures is the alien probe, that nobody confirms to keep in warehouses. The probes would be the first crafts that enter our solar system when hypothetical aliens are coming.

If there is a manned alien spacecraft. That travels in the universe, there would be a fleet of drones or probes traveling ahead of manned units. Those probes' purpose is to search for interesting targets for that hypothetical spacecraft and its crew. The craft would be extremely large. And every maneuver that it makes requires lots of energy.

And that means the crew will not break it without a good reason. In one vision the Kardachev Scale 3 civilizations and civilizations above that scale can send interstellar spacecrafts with living crews. And if that is true, our home planet is too primitive for those creatures.

"NASA is expanding its search for extraterrestrial life to include technosignatures, signs of advanced civilizations, beyond just radio signals. This includes artificial chemicals in exoplanet atmospheres, infrared signatures of megastructures, and potential city lights on distant planets".

There is a hypothesis that the "little grey men" are actually robots. The sender of those robots is unknown. (Images: ScitechDaily.com/Searching for Signs of Intelligent Life in the Universe: Technosignatures)

There is always a risk. The microbes pollute craft if the aliens try to send manned recon crafts to search humans or if aliens themselves try to land on Earth. Those microbes can be even deadlier than any ebola because our hypothetical aliens have no immune resistance against Earth bacteria.

So to avoid that risk those hypothetical aliens will not stop in our solar system. And even if they would start to orbit our planet or any similar planet they will operate on the ground by using remote- or AI-controlled robots. The thing makes sure, that any infectious material can split in the alien mothership.

When we think about interstellar traveling the time dilation can keep the crew alive longer than usual. If the craft uses time dilation to keep the crew operational for an extremely long time, that means that the senders of the craft died a long time ago before the crew reached the other solar system. The craft can have a saucer shape, and there is a particle accelerator at its edge. The purpose of that system is to accelerate electrons or protons to a speed, that is close to speed of light.

That particle accelerator will make the time dilation in the cabin, and the speed of the craft would be 20-50% of the speed of light. Centuries and millenniums are traveling outside its shell, and the journey would be one way. The senders will not see those crew members anymore.

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.

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
