The Ingenuity helicopter got its new software. And Perseverance-rover found an organic-looking chemical compound from Mars.

NASA:s Ingenuity helicopter can use to research how to navigate without the GPS.

The Ingenuity helicopter flies over Mars, and one of the problems with this kind of system is simple: how to navigate without the GPS? There are many possibilities for how to replace traditional GPS by using some other systems. One system what that robot helicopter can use in that kind of operation is TAINS (Terrair contour matching and Aided Intertial navigation system). The camera in the helicopter takes images from its route.

And when the helicopter needs to return. The computer compiles images that the helicopter takes with new images. The camera sends that data to the flight-control computer. The inertial or gyroscope navigation can support return.

The gyroscope can record the entire flight route and then the helicopter must just drive that route backward. The TAINS system is a combination of TERCOM (Terrain contour matching) and gyroscope navigation. This kind of navigation system is used in cruise missiles, but it also can use in other aerial vehicles.

Things like robot recon planes can also use the TAINS system. The recon plane can fly a certain route. And its digital cameras store the entire mission. Also, the TAINS system can control unmanned attack aircraft. The point where the navigation system orders the drone or cruise missile to dive into the target can program that way. The aircraft releases a smart weapon at that point.

But there is another way to locate objects and navigate by using satellites than some regular GPS systems. The robot or manned vehicle can send the laser ray to the photo-recon satellite.

The photo-recon satellite will see the location of the laser pointer from the image. The AI or human operator can plan the route for the robot helicopter. Or drive the helicopter to the wanted position by using the remote control. The helicopter can search for interesting points for the Mars-rovers.

Robot helicopters can use laser spectrometers in larger areas than robot cars. The helicopter can also use its laser as the laser drill. And land at the wanted position and then take samples from deeper than just the surface.

Perseverance-Rover found possible organic molecules from one crater on Mars.

New findings from planet Mars are making this kind of combination interesting. The Perseverance rover found organic-looking chemical compounds in one single crater. These kinds of findings are very interesting things. And if those organic chemical compounds are truly organic they should be found all over the Red planet. If the organic-based material is found only in one or two single areas and if there are some fossils.

Or maybe, sleeping bacteria that are not from Earth. That thing opens new roads for cosmology. And search for extraterrestrial life forms. If there are Mars-based bacteria only in Valles Marineris canyon. That proves that extraterrestrial lifeforms can be very local. And even if the planet seems hostile there could be places where life is possible.

But there is one interesting thing. If those bacteria are from Earth, what carried them to Mars? Or what if the bacteria fossils were found in only one crater? There is a needed DNA (RNA) or genome sample to confirm that the pill-looking structures are remnants of the bacteria. And there is the possibility that the UV radiation terminated the genome and internal structure of those proto-bacteria remnants.

When robots are laughing and crying.

When robots are laughing and crying. Does the AI have feelings? Does the AI have feelings? Or can it be emphatic? The fact is this program code that controls the AI determines if it can give empathic reactions. The problem with the human nervous system is that we don't make a difference in the writing of empathic letters or telling empathic stories human or AI. Our nervous system is not adapted to AI yet. And that's why we cannot separate text written by AI from text that made by humans. What does somebody make with AI that can emulate feelings? The fact is that the cyborgs are useful tools for infiltration operations. The human-size robots can have WLAN/6G connections with the central computers. Or they can form a neural network that shares information between all group members. The robots can also act as walking neural network-based supercomputers. That can make complicated solutions. In those networks, each member shares information and their data-handling capacity all o

Earth 2.0 has been caused discussion about the possibility to find another civilization

Earth 2.0 has been caused discussion about the possibility to find another civilization The Earth 2.0 or officially Kepler-452b is locating extreme log distance from Earth(1). A new Earth-type planet has been found near the star, which is similar to our own Sun. The journey to that planet would take 1400 years, even if the spacecraft will reach the speed of the light. The planet has been found in the year 2008, but the confirmation of the existence of that planet has been taken time, but in 2015 the confirmation has been got, and Earth 2.0 has turned true. The mass of that planet is 1,9 times Earth and the temperature is excellent if we are thinking about liquid water, but the journey to that planet will take so long, that we cannot ever go in there by using regular rockets and technology. The thing is that this kind of planets are the most interesting if we are looking for the lifeforms, which are similar to us, and the problem with that kind of things is that the communicatio

Tunguska meteorite and the natural nuclear fission

Image I Tunguska meteorite and the natural nuclear fission 1) Tunguska UFO-theory Tunguska meteorite is the mystery, that has been solved once, but then the case has been open again because Lake Cheko was not suitable for an impact crater. That lake has been introducing as an impact crater of the Tunguska meteorite. But the problem is that the shape of that lake is like a swimming pool. And that means it cannot form by a meteorite. So the mystery remains. Meteorites can launch the natural nuclear fission if they hit the uranium ore, and transfer the impact energy to that ore. And is the thing that the famous "Tunguska" meteorite caused that kind of effect? There is also a theory that some "UFO" explode in that area, but the thing is that it is only theory, but interesting topics for some TV-series. So I will begin this text by handling that theory, which is one of the incredible and outstanding theories in the world. Officially there is no physical evidence of
