A bright #fireball crossed the evening sky over north-western Europe on Sunday and was widely observed across Belgium, France, Luxembourg, the Netherlands, and Germany. The object was detected by the #AllSky7 network, a system of automated sky cameras used to track #meteors and recover #meteorites. Using multiple recordings, researchers reconstructed the #trajectory of the incoming #meteoroid.
The object was first detected at an altitude of about 85 km, where atmospheric entry produced intense heating and light emission. During its approximately six-second passage, several flashes occurred as the body fragmented. Each fragmentation event likely produced between 10 and 100 #meteorites, meaning the original body broke into many pieces during #atmosphericEntry.
Based on brightness and duration, astronomers estimate the original #meteoroid had a diameter of roughly 1–3 meters. Objects of this size impact Earth relatively frequently, approximately once every two weeks, although most fall into oceans or sparsely populated regions.
Fragments slowed rapidly due to #atmosphericDrag, reducing their velocity from initial ~61,000 km/h in space to roughly ≤700 km/h before reaching the ground. Despite this deceleration, surviving #meteorites can still cause structural damage.
In this case, at least one fragment struck a house in Koblenz (Germany), penetrating the roof and landing inside a bedroom that was fortunately unoccupied. No injuries were reported. The unusual aspect of the event is therefore the impact occurring in a populated urban area, whereas most meteorite falls occur unnoticed in remote regions.
The calculated fall zone is now being searched by meteorite hunters and scientists, as recovered fragments may provide #cosmochemistry evidence about the early #SolarSystem and the composition of #asteroids. -
When the crack of an incoming spaceship comes in, the desert must *really* come alive, especially to those who look up at those crystal-clear skies and dream of touching those little points of light...

🇩🇪 #ATMOS has few competitors, of which #VardaSpace and #InversionSpace both apply parachutes 🪂 for the final descent of their return capsules. #Phoenix doesn’t require parachutes due to its large surface area and low mass, allowing its shape to essentially act as a parachute. The ballistic coefficient is lower than #NASA’s #LOFTID demonstrator. The next Phoenix to launch will carry "green #propulsion; ethane and nitrous oxide” https://www.nasaspaceflight.com/2025/06/atmos-space-cargo

Splashdowns are cool and everything, but you just can't beat the vibe of a spacecraft coming in like wings of fire over the dunefields. My spacey (and, for once, not entirely science-fictional!) vision "Hot entry over the desert".

For a trip to #Mars 🔴, decreasing travel time by 10% necessitates twice as much fuel, while cutting travel time in half requires ten times as much. May prove worthwhile when considering factors such as decreased exposure time to #radiation ☢️ for crewed 👩🚀 missions. Extra speed must be lost at Mars. Many Mars missions do this, taking about 6 6️⃣ to 7 months for transit to the Red Planet. https://marspedia.org/Hohmann_transfer#Type-I_and_Type-II_Trajectories

Parachute 🪂 is not the only means for descent, as high-mass class vehicles are emerging for human 👩🚀 missions. Shallow entry flight-path angles are preferred in order to achieve a lower terminal velocity to ensure a safe descent phase. Retro-propulsion could be activated at Mach 2 and above https://www.intechopen.com/chapters/72944#

For now, the mass of #satellite 🛰️ disposals is just 3% 📊 of the natural input of #meteors ☄️ from space 🌌. But in a future with 75,000 satellites, the injected humanmade mass rises to 40% 📈 that of meteors. Concerns are mostly focused on #aluminum, the most common component in satellites. Aluminum chloride is easily split apart by light, freeing the chlorine to destroy #ozone. https://www.science.org/content/article/burned-satellites-are-polluting-atmosphere
