The International Space Station experiences constant, low-level aerodynamic drag, which causes its orbit to steadily decay. Electrodynamic tethers had long been proposed to generate thrust by using solar power to drive electrical current (collected from the ionosphere in this animation) against an induced voltage, adding orbital energy to compensate... show more

Another explanation for Oumuamua's unusual shape has been proposed The asteroid Oumuamua, which flew through the Solar System in 2017, amazed scientists with its unprecedentedly elongated shape. It is 230 meters long and about 35 meters wide. Astronomers have never seen such objects before and tried to explain its origin. Oumuamua is the first known object to arrive from interstellar space. Its trajectory and speed left no doubt that it does not belong to the Solar System. The object rotated around its axis, changing its brightness, which made it possible to determine its size.

The pilot was unable to recover the aircraft from the roll, and by the time he realized what was happening, he was already too close to the ground. If the jet had a higher thrust-to-weight ratio, it might have had a better chance of recovering. Delta wings rely heavily on high angles of attack to generate lift at low speeds. This results in: High induced drag Significant vortex drag Rapid energy loss during turns Keeping the nose up to maintain a high angle of attack also reduces the pilot’s ability to see the ground, limiting situational awareness. Altitude warnings are then the primary source of awareness, but during airshows pilots often disregard these alerts because they know they will be performing low-altitude maneuvers. This is one reason we saw no ejection from the Tejas. Being at low speed, low altitude, in an under powered jet, operating a delta-wing aircraft under high drag and vortex drag, and having the nose slightly up, thereby reducing forward and downward visibility, means the flawed design of Indian Tejas contributed to the Tejas crash. I have frame freezed in the video where any other jet would have successfully got out of this roll but Tejas crashed. The machine betrayed the man and a pilot was lost. I will place the blame of Tejas crash on politics and designers.

🚨 CHINA IS RACING TO BUILD A SPACE SOLAR POWER PLANT THAT COULD BEAM ELECTRICITY FROM ORBIT TO EARTH. Scientists at Xidian University have successfully tested a ground-based system that can wirelessly transmit kilowatt-level power over 100 meters using microwaves. Their ultimate goal is far more ambitious: placing large solar power stations in geostationary orbit (36,000 km up), where sunlight is available 24/7 with no weather or atmosphere blocking it. The project, called Zhuri (“chasing the sun”), uses mirrors to concentrate sunlight onto solar panels, converts the electricity into microwaves, and beams it down to a receiving antenna (rectenna) on Earth. Why this matters: • In space, solar energy is up to 6 times more efficient than on Earth because there’s no night, clouds, or atmospheric filtering • A single large space solar station could theoretically generate gigawatts of continuous clean power enough for millions of homes • The team has already proven the system can beam power to multiple moving targets at once • China is now among the world leaders in this technology, alongside the US and Japan The deeper implication: Space-based solar power has been a dream for decades because it could provide truly baseload renewable energy. While the technical and financial challenges are enormous (building massive structures in orbit, precise microwave beaming, and safety), steady progress like this brings the concept closer to reality. If successful, it could fundamentally change how humanity generates and distributes energy moving power collection off the planet entirely. Near-term applications could include wirelessly charging satellites or powering future lunar bases. Do you think space-based solar power will become a major energy source in the coming decades, or will it stay too expensive and complex?

M+8: The ISS has multiple airlocks, some are designed for astronauts and equipment, and others like this one, the JEM airlock from the Japan Aerospace Exploration Agency, are designed not for humans but for small payloads. This particular airlock is positioned next to a Japanese platform for payloads that sits outside the ISS. We can use this airlock to take stuff inside to space, or from space to inside. 大西卓哉（JAXA宇宙飛行士）Takuya Onishi and I worked together to assemble the sliding table so that we can deliver science payloads to the outside of the International Space Station. Then we double checked the airlock interior to ensure we didn’t leave any tools or equipment inside which could get unintentionally lost in space.

Our aero kit for the 2024+ Model 3 Performance is designed using CFD to enhance performance while preserving Tesla’s renowned efficiency. Shown here is the exploded view of the aero kit parts to show how we accomplish our goal: to work with the Model 3 Performance foundation without disturbing it. The kit now delivers 1896N of downforce, shifting the car from net lift to substantial downforce with a minimal drag increase of just 1.93%. This is achieved through advanced aerodynamic techniques, such as splitter tunnels that enhance front ground effect—features rarely seen on street-legal vehicles. The kit enhances downforce in areas that already have high-pressure air, such as above the grille, over the side inlets, and on top of the front splitter, but also introduces entirely new shapes like the front undertray. Airflow management around the wheels and side skirts is critical for reducing drag and offsetting the added drag from downforce-generating surfaces. Additionally, placing a wing that is highly optimized to minimally disturb Tesla’s refined wake is crucial for maintaining efficiency. While we’re working out a few more final touches with our production run, we are just as excited to reach out to those who have patiently waited and look forward to providing order updates soon!

🚨 SPACEX IS ABOUT TO TEST A RADICALLY DIFFERENT KIND OF SPACECRAFT AND IT COULD UPEND THE ENTIRE ORBITAL MANUFACTURING INDUSTRY. On Tuesday, SpaceX plans to fly the first prototype of Starfall, a flat, disk-shaped reentry capsule designed to return up to 1,000 kilograms of cargo from orbit in a single flight. That’s roughly 30 times more payload capacity than current commercial return vehicles (like those from Varda Space Industries). It’s not a scaled-down Dragon it’s a completely different approach: no onboard deorbit engine, a wide flat disk geometry, and Starlink terminals mounted to maintain communication through the plasma blackout during reentry. Why this matters: • Current orbital manufacturing companies are limited to returning only dozens of kilograms per mission • Starfall’s design could make large-scale commercial production in space economically viable for the first time • SpaceX would be directly competing with companies (like Varda) that currently pay SpaceX to launch their capsules • Successfully testing Starlink through reentry plasma would be a major technical win with applications across SpaceX’s vehicles The deeper implication: SpaceX is quietly expanding its vertical integration. They already dominate launch. Now they’re moving into the return leg of the orbital manufacturing supply chain the part that has been the biggest bottleneck for companies trying to make products in microgravity and bring them back to Earth. If Starfall works at scale, it doesn’t just give SpaceX another revenue stream. It gives them significant control over the economics of an entire emerging industry. The disk shape and high-capacity design suggest they’re thinking about high-cadence, lower-cost returns rather than the traditional high-value, low-volume approach. This is classic SpaceX: take an existing problem (expensive, low-capacity return from orbit), apply first-principles thinking to the vehicle design, and try to make it dramatically cheaper and higher volume. How do you think this move into orbital return changes the competitive landscape for companies trying to build businesses in space manufacturing? Follow for more analysis on SpaceX’s expanding role across the space economy.

😓 Air India 🇮🇳 Flight AI171 with fully loaded Boeing 787-7 Dreamliner fatal accident: I‘m an airline pilot with >15‘000h of experience and a physics institute: My brief PRELIMINARY analysis of the visible facts from the video of the takeoff: * The flaps are only slightly extended, presumably to position 1 instead of 5. * The landing gear is still extended, which should have been retracted at this altitude and causes additional drag. * The aircraft is at a high angle of attack, which confirms the insufficient flap setting. * From the video and witness accounts, only low engine noise is audible. * Neither smoke nor fire is visible. * An engine failure is less likely. The most probable cause is presumably a human factor, an incorrectly chosen, insufficient flap setting for takeoff, and consequently an inadequately selected thrust. In this context, the correlated speeds were too low because they were calculated for a larger flap setting or a lighter aircraft. As a result, the aircraft took off with insufficient speed and intentionally but falsely derated thrust, was therefore on the unstable side, and rapidly lost more speed and altitude due to the additional failure to retract the landing gear in a timely manner, leading to a subsequent stall at low altitude and crash. For the experts: the aircraft got onto the wrong side of the speed vs drag curve and maneuvered itself into a corner from where there is no escape. Another possible cause could also have been an incorrect input of a wrong takeoff weight into the Flight Management System, resulting in too low thrust and too low speeds. The pilots got startled after takeoff, couldn’t wrap their head around what went wrong and incorrectly prioritized making an emergency call instead of flying the aircraft first, manually increasing thrust immediately to maximum, and retracting the landing gear. In summary of this very early and preliminary assessment (your confidence level should be as low as mine): The most probable cause is human error 😓 - as most of the time these days. Not because the pilots got worse (although that effect can be observed as well with prioritization of diversity over competence) - but because technology got so much better.

Japan’s leap into the deep blue has birthed a technological titan: the world’s first megawatt-scale underwater turbine designed to anchor within the relentless Kuroshio Current. Unlike solar or wind energy, which are beholden to the whims of the weather, this subaquatic marvel taps into ocean streams that flow with permanent, unshakable consistency. Because water is roughly 800 times denser than air, even a slow-moving current carries a kinetic punch far more powerful than a howling gale, allowing these massive "sea-planes" to generate a steady, "always-on" stream of green electricity that could theoretically power the nation 24/7. The sheer scale of this ambition is staggering, as researchers estimate that the energy pulsing through Japan’s coastal waters could reach a capacity of 205 gigawatts—nearly enough to match the country’s entire current power generation. These turbines operate like inverted satellites, hovering in the water column and using sophisticated sensors to maintain stability against the crushing pressure of the depths. By transforming the silent, eternal movement of the Pacific into a high-tech power plant, Japan isn't just building a gadget; it is effectively turning the ocean into the planet’s largest, most reliable natural battery.

Faraday's Law of Induction ✍️ It describes the phenomenon of how a changing magnetic field around a wire can "force" electricity along its length. As the magnet is moved up and down through the wire coil, the magnetic flux (the number of lines of force) is constantly changing. This constant change leads to an electromotive force (EMF), which behaves like a battery, providing the necessary power for electrons to flow and generate electrical current. The video demonstrates that electricity is not produced simply by placing a magnet near the wire but rather by moving the magnet. The rate at which the magnet is moved dictates how much electricity is created. Nevertheless, as seen from the chart, the movement of electricity ceases completely when the magnet remains stationary, regardless of whether it is inside the coil. Video 📸: py6cj

The housemates had mentioned that this person was told that the pot was washed for Faith to use. While this heated situation happened, words were thrown and Faith responded, which is human. Although he might have said somethings that could easily be taken out of context. For the longest time, Faith has been known for taking insults with a smile. But this is not the first time he had been taunted by this housemate, so we understand why he would react.

To presume that there is an inherent flaw in the RBR Macarena wing design due to the rotation of its flap leading to Max’s issues is fundamentally flawed because Hadjar hasn’t had an issue with it yet. It’s not mental gymnastics folks…it’s engagement bait…. And it doesn’t make sense from an aerodynamic standpoint…either. 😁 Simple thought exercise. Pressure is force acting on an area. Pressure builds as air molecules crash onto an aero surface e. Force acts perpendicular to the surface and can be resolved in drag force and downforce (or lift) force components. Where is the pressure on the RBR wing just before it closes? Don’t believe me? Also my mate Balaskó Dominik did an excellent CFD simulation on his LinkedIn page showing this exactly.

China has become the second country in the world with an orbital-class launcher system with first-stage booster recovery through controlled reentry and propelled landing. After delivering its payload to low Earth orbit, The Long March 10B had its booster landing on a recovery ship in the South China Sea with a net-and-hook system. SpaceX has more than a decades lead on the Chinese, with Starship being at a completely different position in this space race but the Chinese are clearly going to be putting a lot of effort into trying to catch up. It’s remarkable that the Europeans have been so slow to start experimenting with these technologies. ESA and ArianeGroup have been slow off their feet and both the Themis and Callisto programs are still very far from pulling off what the Chinese did today and miles and miles away from being able to do what SpaceX does.

As IDF operations continue in Nasser Hospital: 🔴 IDF troops uncovered medications with the names of Israeli hostages inside the hospital along with weapons. 🔴 A report was received regarding the failure of electrical systems within the hospital. Our troops worked to repair the generator while bringing an alternative one. In addition, the IDF supplied food for infants and water to the hospital. This was carried out with the Coordination and Liaison Administration for Gaza (CLA). The IDF will continue to operate in accordance to international law against Hamas which systematically operates within civilian infrastructure.

Here is a 3D visualization of the coming solar storm using model parameters from NASA's run, NOAA's run (shown below), and the coronagraph views from STEREO-A/COR2 and SOHO/LASCO. The storm is expected to hit Earth early December 9. The 3D visualization clearly shows the low inclination orientation of the solar slinky core inside the larger storm envelope. Of course, the earlier eruption that erupted to the northeast, might deflect this structure a little bit, but likely that will only make the structure move more towards the ecliptic plane, which will give us a larger chance of crossing through the solar slinky core. One nice thing about low inclination flux rope cores is that they almost ALWAYS have southward field in them at some point. So this is good news for aurora photographers-- as long as this solar storm stays true to its launch trajectory and inclination, we could see some organized southward pointed magnetic field. Considering this solar storm is fast-- that usually indicates the storm will not deviate much from its original launch trajectory! Here is the link to a static frame of the 3D frame visualization so you can fly around it yourself:

🇷🇺 Andrey Bezrukov, advisor to the CEO of Rosneft, Igor Sechin, stated yesterday at the St. Petersburg International Economic Forum (which itself came under Ukrainian attack) that Russia will remain in a state of war for the next “two decades”. According to him, Russia must learn to live under wartime conditions, and its state system and economy must be restructured not only for development but also around defense. He also noted that two “wartime generations” will be formed in Russia and admitted that Ukrainian drone strikes, which now reach any region of the country, have become a serious problem for which Russia was unprepared. This is a very frank and long-term assessment coming from a senior figure within the Russian establishment. The admission that Russia is preparing for decades of war, along with the recognition of the serious threat posed by Ukrainian drones, reflects the growing realism (and concern) even among those close to the Kremlin’s power structures.

According to him, Russia must learn to live under wartime conditions, and its state system and economy must be restructured not only for development but also around defense. He also noted that two “wartime generations” will be formed in Russia and admitted that Ukrainian drone strikes, which now reach any region of the country, have become a serious problem for which Russia was unprepared. This is a very frank and long-term assessment coming from a senior figure within the Russian establishment. The admission that Russia is preparing for decades of war, along with the recognition of the serious threat posed by Ukrainian drones, reflects the growing realism (and concern) even among those close to the Kremlin’s power structures.

🚨 JUST IN: President Trump says the Supreme Court has treated Republicans FAIRLY and that we will right the wrong of birthright citizenship through Congress “The biggest and most consequential Decision issued by the Court, by far, is the Slaughter Case, which overturned the very famous Humphrey’s Executor Rule. This whole concept of “Power” has been fought over for nearly 100 years, going all the way back to Franklin Delanor Roosevelt, where a large slice of his Power was taken away. He fought to regain it, even wanting to “pack the Court,” but was unsuccessful in doing so. This Decision gives tremendous additional Power back to the Presidency, where it belongs. It is an Honor to be the sitting President who, after all these years, WON this very important, and hard fought, Case.” “We had other good Victories, too, and we also had the Birthright Citizenship loss, which we will work to correct in Congress, but the big SLAUGHTER, was SLAUGHTER. The Republican Party was treated very fairly by the United States Supreme Court. Thank you for your attention to this matter! President DONALD J. TRUMP”
