NASA OSIRIS REx mission reveals Asteroid Bennu's sub-surface.

The "Osiris REx" mission will take the Osiris probe closer to asteroid Bennu than ever before. The spacecraft's mission is to research the sub-surface of asteroid Bennu and take samples of that 500 meters long asteroid to Earth. These kinds of missions are interesting. And they can also help to find out how our planetary system and even life has been born on Earth. There is a possibility that the origin of life is stored in some asteroids. 

The asteroids are very interesting targets also for R&D work that helps to develop spacecraft and probes. The probe that can operate very far away from Earth must find the right asteroid by using an image-scanner. That is connected with a plasma spectrometer. The laser system vaporizes a small mass of the material of the asteroid. And the plasma spectrometer will just measure the fingerprint of the asteroid by comparing the relations of elements. 



This thing is important if the probe must find the same asteroid twice. The probe must fly very close to an asteroid for taking the sample. The collimation with an asteroid can cause damage. When the probe hunts the right asteroid it must use the ion rockets for making quite complicated maneuvers. 

And that's why the asteroid probes are serving the R&D process of the AI and ion engines. Those systems are necessary when the next-generation probes and rovers will send to icy moons of the outer planets. The asteroid probes can also serve the R&D work of killer satellites and the counter-actions against the satellite killers. 

The ion engine can help the satellite escape from the route of the ASAT (Anti Satellite) system. But the same system can also shoot ion spray against incoming kinetic-energy satellite killer. The most important tool for killer satellites is how to recognize the right target. And that kind of satellite must make multiple maneuvers. So the necessary technology can test in asteroid belts.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
