How #Colibri flies: 30-meter free flight explained! 🚀 Colibri’s flight is like balancing a pencil. The Thrust Vector Control (#TVC) tilts the engine, just as you move your hand to keep the pencil upright, while cold gas thrusters stop any spinning. The N2O/IPA engine's 1 kN thrust, adjustable between 25% and 125%, helps with precise altitude control. Sensors like #RTK GNSS, lidars, and an Inertial Navigation System (#INS) guide these adjustments, ensuring Colibri stays stable throughout the flight. They work like your eyes guiding your hand as you balance the pencil.

Today, civil aviation ✈️ relies heavily on manual air traffic control and #GNSS🛰️. But increasing the efficiency of future air traffic will require a highly automated system. Enter #MIAR. In this video🎬, Florian Selig and Ayse S. from the German Aerospace Center (DLR) explain how the project is advancing new integrated concepts for communication, navigation and surveillance – marking a game changer in the development of safe and efficient systems for tomorrow’s #ATM. #SESARJUprojects #DigitalSky #SESARJU #HorizonEU

Drones that fly #BVLOS over long distances can form the basis of numerous commercially attractive as well as economically and ecologically useful operating scenarios. However, up to now, the necessary permits have often been lacking. "The recently launched demonstration flights of the Heron TP drone are not only a milestone for the German Armed Forces, but should also be a milestone for commercial #unmanned aviation", says Dr. Gerald Wissel, CEO of the UAV DACH industry association. "After all, the #drone economy is technically and structurally capable of operating #UAS safely over long distances." Thanks to a permission from the German Armed Forces Aviation Office, the Heron TP may also fly outside military training areas and is therefore fully integrated into general airspace. "What we as a society accept for an aircraft weighing several tons with a wingspan of 26 meters should also be possible for UAS with a take-off weight of a few kilograms, which are operated in compliance with all legal requirements", demands Dr. Gerald Wissel.

A Galaxy Cluster with Crossing Gas Streams | NASA's Chandra X-ray Observatory FriendsofNASA.org: Astronomers using NASA’s Chandra X-ray Observatory have found a galaxy cluster that has two pairs of streams of superheated gas crossing one another. Researchers have discovered a pair of enormous, comet-like tails of hot gas—spanning over 1.6 million light-years long—trailing behind a galaxy within the galaxy cluster called Zwicky 8338, or Z8338 for short. This tail was spawned as the galaxy had part of its gas stripped off by the hot gas it is hurtling through. What makes this remarkable is that this is the second pair of tails trailing behind a galaxy in this system. Previously, astronomers discovered a shorter pair of tails from another galaxy nearby to this latest one. This newer and longer set of tails was only visible due to a deeper observation with Chandra that revealed fainter X-rays. Astronomers also found evidence that the streams trailing behind the speeding galaxies have crossed one another, causing the shorter pair of tails to be detached from the galaxy they are trailing. These galaxies are in motion because they were part of two galaxy clusters that collided with each other to create Z8338. This makes Z8338 a chaotic landscape of galaxies, superheated gas, and shock waves. These are similar to sonic booms created by supersonic jets. Why is this important? Z8338 is helping to teach astronomers how these galaxy clusters, among the largest objects in the Universe held together by gravity, evolve over time. More specifically, this result gives them information about how the galaxies that are part of the cluster interact. This includes how this complex system can allow new stars, planets, and other structures to grow in the future.
