"Van Allen belts also fluctuate and can sometimes descend to an altitude of even 500 kilometers above the Earth's surface. And that is also why, among other things, the International Space Station, or ISS, is located in an orbit of about 400 km, so as not to unnecessarily expose itself to the additional layer of radiation that is there. "

"This magnetic shield of ours, which I mentioned, is not, my dears, uniform. It's not some sphere, right? It has some dents, right? the magnetic field fluctuates and there is something called the South Atlantic Anomaly. And my dears, this is a place where this Van Allen belt reaches approximately 200 km above sea level. So you see, much less than the 1000, which is, well, more stable, I would say. And here we must take this into account when organizing various manned flights. "

"The fifth day will bring a significant change in the physics of the entire flight. Because on that day, the Orion spacecraft will officially enter the so-called lunar sphere of influence. The moment the vector of attraction between Earth and the Moon changes and the Moon's attraction begins to prevail, from that specific moment, from an astrodynamics perspective, the Moon, not Earth, takes over as the main object dictating Orion's flight path. "

"The Orion spacecraft's crew module itself, this capsule here on top, will mechanically separate from this rear European service module. The European module, its engines, which reliably brought the crew to the Moon and back, will detach and be destroyed. "

"“The translunar injection burn (TLI) propelled Orion on a path toward the Moon and set it on the free-return trajectory that will ultimately bring crew back to Earth for splashdown.” "

"This will be the first of a total of three return trajectory corrections responsible for microscopic course adjustments, so that Orion hits its target entry point into the Earth's atmosphere, meaning we don't just randomly land anywhere, but precisely splash down where they are supposed to splash down. "

"Friction and gas compression will be so powerful that a hellish temperature of over 3000 degrees C will be generated on the very outer side of the heat shield. The heat shield must take all of this upon itself to maintain a tolerable safe temperature in the cabin. "

"The sixth day of the mission is the absolute culmination of the entire expedition. The crew will be closest to the Moon on this day, while simultaneously being farthest from Earth in the entire history of crewed flights. "

"Translunar Injection is essentially the foundation of every journey to the Moon, starting from the Apollo program. It is a powerful, final firing of the spacecraft's main rocket engine near Earth. "

"The Artemis 2 mission is primarily a 10-day crewed test flight. A four-person crew will be on board the Orion spacecraft. The American agency NASA will be represented by Ray Wiseman, Victor Glover, and Christina Coch. They will be joined by Canadian astronaut Jeremy Hansen, representing, of course, the Canadian Space Agency, and their task is to travel around the Moon and back, during which Flight Control teams will meticulously verify the operation of all key Orion systems. "

"the Artemis program has been ongoing for a few years. Of course, we already had a flight, a similar profile, because we had a flight of the Orion capsule around the Moon as part of the previous mission. However, it was an uncrewed flight. There were, as you remember, crew members in the form of mannequins with a lot of sensors. In one of them, over 1000 different types of sensors were installed. So that what will most likely happen on April 1st can safely take place. "

"A private company will land on asteroid Apophis during its close flyby of Earth. My dear friends, two landers belonging to a private American company will be part of a fleet that in 2029, that's very soon, no, 2026 is already ending, because it's already March. "

"Particles ejected by the sun displace more dangerous energetic cosmic radiation from outside the solar system. Well, we won't catch all of them, but still, a lot of accelerated protons flying from the sun are able to interact with these particles from outside our solar system. And well, it works a bit like those anti-missile domes, you know? That a certain number of these missiles fly, and we also have a certain number of these missiles, and simply some of them will interact somewhere. "

"General relativity and quantum mechanics are two of our most successful theories in physics, but the problem is that they are incompatible. "

"Quasicrystals are not just purely mathematical structures, existing exclusively on paper and in the minds of mathematicians. They also exist in reality and have been successfully created in laboratories worldwide. Their structure is so unique that in 2011, the Nobel Prize in Chemistry was awarded for their discovery. "

"The movement of small quantum particles in such a discrete spacetime would depend on the angle at which they move. Their behavior would differ depending on whether their trajectories are parallel to the lines of our grid or not. And this would generate observable consequences, tangible differences. Differences that we certainly do not observe in our universe. "

"fermions are particles, indivisible particles, that our world consists of composite particles of quarks, but additionally we also have electrons, we have corresponding neutrinos and these electrons, muons, taus, yes, with other neutrinos respectively electron, muon and tau neutrinos, and on the other hand also three families of quarks, which form such pairs and from which these families of quarks are built mesons and particles such as hadrons, right? "

"We assume they are composed. Each of them consists of three quarks, but in reality, these three quarks or these two protons are some kind of energies. At the moment we collide them, it's not that suddenly six quarks are formed and they wonder, 'okay, we here, we here and fly away,' instead, energy is created, from which something completely different condenses. "

"This was the first full-scale test in history of planetary defense technology, which was supposed to prepare us for the worst-case scenarios. "

"The American space agency NASA, as part of the historic mission named DART, decided to deliberately and with full premeditation crash a speeding spacecraft into the surface of a distant asteroid. However, the purpose of this endeavor was absolutely not some blind destruction or, I don't know, causing cosmic fireworks. The intention of the scientists was to rigorously test the so-called kinetic impact method in real conditions. "

"Nowadays, we already know well, thanks to this experiment among others, that we do not need to construct gigantic atomic bombs straight out of old science fiction movies to deal with such asteroids. We only need precise equipment, great mathematics, and a precisely timed kinetic nudge of a mass, which over many years will naturally grow into a powerful and civilization-saving change in its entire flight path. "

"The American agency NASA literally hit an asteroid, and the physical and astronomical consequences of this event turned out to be much more spectacular, groundbreaking, and instructive than anyone initially assumed. "

"The true goal is a subtle but lasting change in the velocity of the cosmic rock. Just a fraction of a millimeter/ounce of velocity change today, summed over years of uninterrupted flight in vacuum, will translate into tens of thousands of kilometers of shift in its orbit after several decades. "

"The mission proved highly successful. The collision shortened Dimorphos's orbit around Didymos by 32 minutes. Since then, astronomers have continued monitoring the asteroid system, gathering nearly 6,000 observations. These measurements show that the pair's overall orbit around the Sun slowed by about 11.7 micrometres per second—roughly 40 millimetres per hour—reducing the radius of their orbit by an estimated 360 metres. "

"When the DART probe, accelerated to enormous speed, hit the surface of Dimorphos directly, it not only crushed itself and embedded into the rock, giving up its energy, but also blasted a powerful crater into space and a lot of matter with enormous force. It ejected over a million kilograms of debris and various ore, as I'll call it, which simply fell out of this moonlet. "

"“In the spirit of the season, the interstellar comet 3I/ATLAS is changing color as it leaves the sun behind — shifting from a reddish tint to a faint green glow. That visible change signals the comet is reacting to solar heat and releasing new gases in space, giving scientists fresh clues about what it is made of and how it behaves.” "

"Among other discoveries, scientists confirmed that this interstellar comet is the fastest ever recorded, and is covered with ice volcanoes. "

"Using the powerful radio antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers detected extremely strong signals of methanol, a simple alcohol molecule, in the expanding cloud of gas of the comet with the chemical formula CH3OH. "

"Here, it's also important in the context of whether Atlas developed this crust, thanks to which it didn't lose mass. And this comet, because normally if it were flying and was such an uncovered ice, it shouldn't even fully reach our solar system, if we estimate its age correctly, of course, because it would have evaporated anyway, even by being in this interstellar medium. However, my dear friends, thanks to this crust, which was much less penetrable by radiation, it could travel safely and reach the solar system. Well, that's the hypothesis. Of course, we don't know 100% if this mechanism worked, but this one seems the most sensible, because we know that such crusts form and are present. "

"Measurements show that methanol occurs in significantly larger quantities compared to hydrogen cyanide than astronomers usually observe in comets from our solar system. And this is another differentiating element, meaning Atlas, from comets that originate in the solar system. "

"The next launch of a rocket from a repaired launch pad is scheduled for March 22. Soyuz 2 will carry the Progress MS33 supply capsule with supplies for space station astronauts into space. "
