An X4.5 flare generated a fast, asymmetric full halo CME. The bulk of the CME is directed eastward, with an Earth-directed component. CACTus estimated the speed of the CME at approximately 1135 km/s. Likely to impact Earth on Sept 16th.

The observable Universe is ~4.40×10²³ km, or 28,500 Megaparsecs (Mpc) across. It expands at ~71.17 ± 0.86 km/s/Mpc. This is a logarithmic scale conception of the observable universe [✏️ Pablo Carlos Budassi]

The colony drop from Gundam The Origin movie. The structure is 4.5 billion tons striking at nearly 11 km/s. That's 65 gigatons of energy. Its sectional density is 139 tons/m^2, meaning it would easily get through the 10 tons/m^2 atmosphere.

This is how fast Earth flies through the galaxy. The solar system, including Earth, revolves around the center of the Milky Way at a speed of about 230 km/s. At first glance, this seems impressive. But when compared to the diameter of our planet (approximately 12,750 km), on a cosmic scale, it all looks almost like slow motion.

🚨🇷🇺The ATACMS and Storm Shadow are now useless: Russia has upgraded its Pantsir M System Spotted in Ukraine, the modernized Pantsir-S1M represents a radical evolution in Russian air defense, effectively transforming a point-defense system into a medium-range contender. The key is its new, combined arsenal. It retains standard 57E6 rockets but now deploys new 57E6M hypervelocity missiles reaching Mach 5 with a 35+ km range. Coupled with a radar twice as powerful, it can detect targets like the F-16 from 60 km away. Performance against key threats like HIMARS rockets has doubled. Engagement range jumped from ~8 km to over 13 km. Critically, its max target speed is now 2,000 m/s—a figure approaching the Patriot PAC-3's 2,200 m/s capability, despite a vast cost difference. The upgrade includes a kinetic hit-to-kill warhead and enhanced anti-jamming systems. When networked, it can challenge a vast spectrum of Western munitions—from Storm Shadow cruise missiles to ATACMS ballistic rockets and drone swarms.

A tire blowout at 160 km/h—still rock steady? Watch as William tests the ET9's resilience during a high-speed blowout. Thanks to the Full-Link Ultra-Low Latency capability, which reacts in under 0.3 seconds—faster than a blink of an eye—millisecond-level tire pressure sensors detect danger instantly. Meanwhile, the SkyRide intelligent chassis, featuring Steer-by-Wire, Rear-Wheel Steering, and Full Active Suspension, takes control to stabilize the vehicle. Unshakable safety, even at the limits. #NIO #ET9 #NIODay2024 #BlueSkyComing

O-train line 2 and line 4 are really something else. The trains are incredibly smooth quiet very low vibration even when they’re moving at 80 km an hour on the high speed stretches. Big spacious and warm. The stations themselves also are very fun to explore with a lot of glass.

2034 Earth–Venus–Mars opportunity looks promising. 10–15 on-orbit refueling operations may be needed to make a crewed ship full. Most can be done at an altitude of 180–200 km, made possible by Starship’s size. The final refueling may be performed at a higher altitude of ~2000 km, just below the Van Allen belt. Earth departure on 2034-08-21 from 2000 km orbit. A Trans-Venus Injection burn of ~3.7 km/s will place the ship on an Earth–Venus–Earth free-return trajectory. Venus flyby is expected on 2034-12-19, 120 days after departure. Two weeks before the encounter, if the mission proceeds as planned, a 25-m/s maneuver will shift the trajectory from Earth-return to Mars-bound. If not, the ship will free return to Earth in September 2035. The Venus gravity assist will send the ship into another Earth free-return trajectory, with Mars flyby around 2035-06-02. One week before reaching Mars, a system health check will determine whether to commit to Mars Orbit Insertion. If it’s GO, a small 10-m/s manuever will put the ship to less than 100 km altitude periapsis. Otherwise, a Mars flyby will lead to an Earth return in May 2036. The ship will enter the Martian atmosphere at about 9.4 km/s, performing an aerobrake to slow to 4.88 km/s and capture into a 100x140000 km, 7-day period high elliptical orbit. At apoapsis, a 50-m/s plane change will align the inclination with Mars’ equator, followed by additional aerobraking to remove about 650 m/s of velocity, placing the spacecraft in a 120x6128 km orbit. A 550-m/s burn at 6128 km altitude will then adjust the trajectory into Phobos orbit. The ship will stay at Phobos for about 7 days. The Mars–Phobos L1 point is only about two miles above Phobos’ surface, and Mars would dominate nearly half the sky, appearing about 80 times larger than the Moon from Earth. The ship will depart for Deimos afterward. Two burns totaling roughly 750 m/s will transfer the ship from Phobos to Deimos. And the ship will stay at Deimos for 7 days more. From Deimos, the ship will raise its apoapsis to form a 20000x140000 km altitude, 7-day orbit, requiring about 420 m/s of delta-v. At apogee, a 50-m/s burn will adjust inclination and lower periapsis to ~500 km for final Trans-Earth Injection. If time and propellant allow, the orbit can be aligned to a polar inclination for Mars ice-cap observations before departure. A Trans-Earth Injection burn at 500 km altitude, requiring 1.5–1.6 km/s of delta-v in early July 2035. If departure on the first days in July, Earth arrival is expected in December 2035. If missed that window, a March 2036 arrival may look more feasible. Nominal mission duration: 490 days, with 30 days in Mars orbit and 14 days at Phobos and Deimos.

China’s high speed trains travel at around 350 km/h while passengers work, have coffee or sleep as if they were on a regular commute. The scale behind that experience is remarkable. China’s high speed rail network now extends beyond 50,000 km, supported by an immense system of tracks, bridges, tunnels, signalling, power infrastructure and continuous maintenance. The next generation CR450 is being developed for commercial speeds of around 400 km/h, which will demand advances in aerodynamics, braking, energy efficiency and passenger comfort. For me, this is where innovation becomes truly interesting. Progress is not only about achieving a higher speed or a bigger number. It is about turning complex technology into something reliable enough to become part of everyday life. The future stops feeling futuristic when people can use it without having to think about the technology behind it. #China #Technology #Innovation #Future

It delivers 562 HP, goes from 0 to 100 in 3.4 seconds, and has a top speed of 325 km/h. It is the wildest version of the LFA. Only 50 units were made. It was launched in 2014 at $445,000. Today they cost between $1.5 million and $2.5 million. And the prices just keep rising.

A scary accident at around 100 km/h — but thankfully, Sumit bhai is safe. 🙏 The Honda City collided with a Maruti Suzuki Brezza at high speed. The impact was serious, but the City's airbags deployed at the right time, helping protect the occupants. ✅ Airbags deployed ✅ Seat belts did their job ✅ Sumit bhai walked away safely Accidents like this are a reminder that safety isn't a feature you appreciate every day — until the day you desperately need it. Drive safe. Speed doesn't give you a second chance. 🙏

Scientists mapped a piece of brain the size of half a grain of rice. One-millionth the size of the human brain. It took them a year and over 1.4 million gigabytes to scan it. They found over 57,000 cells, 150 million synapses, and even some new structures they didn't know existed. Mapping the entire human brain in this level of detail would require all the data storage generated on Earth in a year + a 140-acre data center. But the human brain itself can hold up to ~2.5 million gigabytes of information - enough for ~3 million hours of HD video or 342 years of continuous viewing. It can process roughly 10 quadrillion calculations per second - enough processing power to run over 4,000 high-end gaming PCs all operating at peak ability. And it only runs on the amount of power needed for a single dim light bulb. No technology even comes close to doing what the brain can do. The more we learn about biology, the more complex it becomes. This is God's Glory on display.
