The fleet of mini-probes can travel in the solar systems quite soon.

The new type of space mission might consist of a fleet of miniature probes. And the larger probes that are coming to an asteroid are marked by mini probes. Those systems are operating by using highly advanced artificial intelligence. And they can make many decisions by themselves. 

The NASAs "Psyche" probe is traveling to the asteroid belt and operates using solar-powered ion engines. But the successor of that interesting probe might be something else. It can be the swarm of miniature probes that are traveling in the solar system. 

The fleet of "mini Psyches" can operate in the internal solar system. The idea of the miniature space probes is similar to drone swarms. They are simpler, cheaper, and more limited than full-scale probes. But they can cover a larger area. The miniature probes can operate along with the full-scale probes. 

And search for things like minerals. The miniature space probes are the tool that can observe multiple asteroids in the same mission. The sensors of those systems might be magnetometer, laser-spectrometer which has combined with lidar and laser scanner. And a CCD camera that is connected with a spectrometer. The idea is that this kind of system are using so much integrated technology as possible. 

The sensors of those miniature systems are limited but things like laser systems can integrate into one package. The lens is turning the laser into an effective spectrometer. And when the lens is removed from the route of laser ray that system can vaporize material from the asteroid's surface. The chemical combinations of that material can observe by using the spectrometer. The same laser system can use as a communication tool. And it can also mark the place where the miniature probe is. 

The smaller probes can search objects for the larger-size probes that have more versatile sensors. The idea is that the system is operating by using both types of probes. A large group of simpler probes is searching for the most interesting asteroids from the solar system. And then the larger probes are driving themselves to that asteroid.

More things about granite and minerals

More things about granite and minerals

There are two versions of the granite, one is dark or grey granite which is black because of the high level of iron ore. This kind of stone is not granite, but as you might know, almost every people think that hematite, what is the main iron source is often called granite.

Iron ore is found in the places, where ancient volcanoes have erupted or ancient meteorites have bombed the ground. That's the reason, why in the Great Lakes area in the USA it has found very much iron. Those lakes have been formed by the meteorite dropped in that area, and raised the iron to surface. Iron is a very important metal in many places and the main role of that metal is in the creation of steel.

The thing that makes red granite very interesting is that it is quite a strong mineral, and suitable for many places. But when we are thinking about another mineral, which is also very common in Finland, the gneiss, we are facing the thing that the stripes of that mineral are looking at ilmenite, what is the primary source of titanium. Titanium is very strong metal, which is harder and lighter than steel, and the titanium is a suitable metal in many aircraft and spacecraft structures.

Titanium itself is antimagnetic, and that allows to make antimagnetic and very strong materials and structures. Here I must mention that Soviet  "Alfa"-class submarine has been made by using titanium, as well as MiG-25 "Foxbat" and SR-71 "Blackbird" aircraft, what are all so-called Mach-3 fighters and recon aircraft. The thing in this kind of case is that if we think, that somebody will build spacecraft, the titanium is one of the most suitable metals for that thing.

So when we are thinking about those places, where could be the stories of the strange lights on the skies, we must realize that there is a possibility, that somebody wants people to stay away in some areas. For that use, there is a possibility that those people, or whatever they are could use quadcopters, where are the lights and loudspeakers for making people afraid.

But if we think that those small helicopters would be harmless, that thing is only good hope. If the loudspeakers would give the resonance frequency what would oscillate the bones or water molecules, those systems could be very effective also against the bigger aircraft. So does somebody want to hide something, what is connected with those minerals?
