"The salvation here turned out to be a technique called photon Doppler variography. In reality, it is an ultra-accurate laser speed camera with such cosmic precision. By aiming a laser beam at the surface of this bombarded sample, the system recorded even the smallest frequency shifts of the reflected light, which were caused by internal vibrations of the material. So, just as seismologists analyze earthquake waves that pass through the globe, Zeng's team used a laser to read the speed of sound waves traveling through this compressed alloy. "

"Examples of applications of superionic conductors. Fuel cells. ... Batteries. ... Sensors. and Their interiors are believed to contain a form of water ice called superionic ice. "

"On Earth, we receive with large telescopes, we use large radio telescopes for reception. These are basically two main systems. Well, there are a few more. Well, this Deep Space Network is Goldstone in California. A center that has several telescopes there. There is such a center near Madrid. I had the opportunity to see this equipment there. There is a large 60-plus-meter radio telescope of this network there. "

"The power of this signal will degrade with the square of the distance. That is, twice as far means four times weaker signal. "

"Satellite technology, specifically oceanographic satellites equipped with radar altimeters, continuously measure the exact height of ocean surfaces. Ocean currents and eddies cause minimal, but still measurable, bulges and depressions in water levels. And satellites create real-time ocean topography maps, thanks to which one can choose routes that ultimately allow us to arrive safely and faster. "

"Clocks in orbit are subject to the effects of Einstein's theory of relativity. Due to the enormous speed of satellites and the weaker gravitational field, time flows there minimally differently than on the Earth's surface. Engineers must constantly introduce relativistic corrections for the system to work flawlessly. "

"Municipal water companies receive ready-made maps of problem points. Repair crews are sent exactly where the pipe is just starting to burst. We start to have a small leak, and this prevents interruptions in water supply to homes, businesses, etc., and above all, also prevents undermining of building foundations and other architectural problems. "

"Satellite data allows officials, and above all urban planners, to look at a city as one coherent, living organism. Modern spatial planning is based on continuous analysis of changes in the structure of these cities. Satellites regularly provide high-resolution images that allow us to monitor urbanization processes in real time. "

"Observation satellites are not simply cameras, as it might seem, cameras suspended in a vacuum. They see much more than the human eye. They use advanced hyperspectral and multispectral sensors that record electromagnetic radiation in bands invisible to humans, such as near and far infrared. "

"Healthy plants, rich in chlorophyll, reflect more NIR light and less red light. NDVI results are presented on a scale from -1 to +1, where higher values indicate healthy and well-developing plants. "

"The farmer receives a precise satellite map of their farm, on which they see which exact parts of the field require urgent irrigation, and which are in excellent condition and cannot be over-watered. This allows for precise dosing of fertilizers or plant protection products. They are no longer simply spread evenly over entire hectares, but applied pointwise, only where absolutely necessary. "

"To determine the position of any object on Earth, satellites do not measure distance with a ruler, but rather measure time. Each satellite in orbit has an extremely accurate atomic clock on board, which sends a radio signal containing the exact moment of wave emission. The receiver in your phone or in the courier's car receives these signals from several satellites simultaneously. "

"“Analysis of satellite images allows for early detection of disease symptoms or pest invasions, before they become visible to the naked eye.” “These types of biochemical changes constitute a 'signature' of water stress in its early stage, and it is precisely these that modern technologies can capture.” “FLEX (FLuorescence EXplorer) is to help see earlier what standard optical observation often does not show immediately: a decrease in photosynthesis efficiency.” "

"Because healthy plants rich in chlorophyll reflect near-infrared light in a completely different way than, for example, diseased plants, dried plants, or plants attacked by pests. Thanks to this, farmers and analysts can use vegetation indices that illustrate the health of crops over vast areas. "

"For solving this problem, for example, satellites equipped with synthetic aperture radar, or SAR, which operates in the L-band, are used. These waves can penetrate layers of concrete, asphalt, and soil to a depth of several meters. The satellite registers the so-called dielectric constant of the substrate. And algorithms also show underground anomalies. Including these leaks. "

"Satellite data also helps analyze car traffic, optimize public transport operations, continuously monitor air quality by detecting sources of dangerous emissions or smog. Various types of enterprises that suddenly, in a quiet, strange way, start releasing various substances into the atmosphere. Previously, we didn't really have the possibility to investigate the places from which these pollutions originate. "

"Atmospheric monitoring satellites, for example the European Sentinel 5P, have spectrometers on board, and these spectrometers analyze sunlight that passes through layers of air, and every gas from nitrogen dioxide emitted by, for example, cars, to sulfur dioxide, some aerosols, absorbs light at that specific unique wavelength. This allows for mapping pollution on a continental scale, and with an accuracy of a few kilometers. "

"Satellite data also helps analyze car traffic, optimize public transport operations, continuously monitor air quality by detecting sources of dangerous emissions or smog. "

"The key to all this is a concept worth breaking down, namely precise time synchronization by positioning satellites, such as the American GPS system or the similar European Galileo system. "

"What's more, orbital data is also used to map so-called urban heat islands. What are these islands? Well, these are areas where concrete and asphalt retain huge amounts of solar energy, causing a drastic increase in temperatures on hot days. And thanks to this information, architects know exactly where to plant trees, create parks, to bring relief to residents, to lower air conditioning costs. "

"A GPS receiver measures the distance to each satellite based on the time it takes to receive the transmitted signal. Each satellite is equipped with an atomic clock, which enables the transmission of a signal with information about the predicted position of the satellites and the current time. "

"In this image of the Martian surface, streaks are visible that were formed by wind blowing over impact craters in the Cirtis Mayor region. These streaks extend for about 50 km, and large craters near the center and bottom of the image have an average diameter of about 50 km. "

"Therefore, quantum systems, even at absolute zero, always exhibit some minimal residual vibrations. They always have some minimal amount of energy that cannot be taken away from them in any way. And this is precisely zero-point energy. "

"Modern field theory proves, and here I'm talking about quantum fields, that the vacuum literally teems with virtual particles, and recently their existence has been confirmed with a high degree of probability in an experiment. "

"Congress unexpectedly allocated $700 million for the project in legislation passed in 2025. The new spacecraft would serve as a communications bridge between Mars missions and Earth, supporting future robotic exploration and potentially eventual human missions. "

"NASA is trying to build and launch this spacecraft before the end of the next Mars launch window, which falls at the end of 2028. "

"The project assumes the development of a reusable aircraft capable of transport, in the sense of a reusable spaceplane capable of transporting cargo to low Earth orbit, performing autonomous orbital missions, and eventually also transporting astronauts. "

"Artemis V is also when NASA is expected to begin building its Moon base. "

"For Falcon 9, this means it will hit the surface in one piece, retaining every unit of its momentum until a fraction of a second before contact with the regolith. The collision site has also been selected. It is the vicinity of the Einstein crater located on the so-called visible side of the Moon, near its western edge. "

"Then the media reported that another Falcon 9 stage would hit the Moon. And only after more detailed analyses and trajectory checks did it turn out that this space debris was actually a fragment of the Chinese Change 5T1 mission. This time there is no mistake. Astronomers have been tracking this particular rocket fragment since its launch in January 2025 and have collected over 1000 data points. So we are sure, SpaceX will visit the Moon in a slightly less controlled way than in the case of the HLS lander, or at least that's what we would want. "

"Its empty weight is 2700 tons, but when the launch platform and the SLS rocket are placed on it, the mass increases to 6000 tons. It's a movable island with dimensions of 40 by 35 m, which is roughly the size of a basketball court. "
