In the lingo of space flight operations, the probability of a spacecraft collision is called a conjunction - a predicted close approach between two objects in orbit.
While the volume of collision-avoidance maneuvers recently executed is breathtaking: >140K over the past 6 months by Spacelink alone. Autonomous on-board systems orchestrate the vast majority of these avoidance maneuvers.
In the latest TechAptitude post we explore the core concepts and technologies deployed for automated collision avoidance in today’s satellite constellations. https://techaptitude.substack.com/p/satellite-collision-avoidance-technology #Space #Satellites #CollisionAvoidance #AutonomousSystems #Software

So apparently the #KesslerSyndrome has already started. The amount of avoidance maneuvers grew 3x over the last 6 months, and the amount of junk in the orbit went up by <s>40%<\s>63% <a href=https://spectrum.ieee.org/kessler-syndrome-space-debris> [1]<\a> over the last 5 years.
What now? It's hard to internalize that it's already here. It will be a quick ride from now. It goes exponential. Hug your GPS, satelite tv, the weather reports, the space photos. It's the end of the space age. We will be telling our grand children how cool it was.
And maybe, if they are lucky, the moon will herd the debris into an orbital ring. It will be magnificent.
What should we be doing to prepare for this? What are your thoughts?
READY TAKEOFF?.... Can These Self-Flying Planes Transform the Skies?

A Southwest Airline jet heading to Las Vegas from Southern California took a dramatic plunge shortly after takeoff Friday in response to an alert about a nearby plane, injuring two flight attendants, authorities and passengers said. Southwest flight 1496 was responding to an onboard alert about another aircraft in its vicinity, the Federal Aviation Administration said. The FAA is investigating. The crew responded to two air alerts that required the pilot to climb then descend, the airline said in a statement. The flight departed from Hollywood Burbank Airport just before noon.
Alors que l'utilisation de l'espace connaît une expansion sans précédent, les débris spatiaux représentent une menace pour la sécurité des satellites et des missions spatiales. Cet article explore les risques de collision et l'impact environnemental de cette pollution, tout en mettant en lumière les solutions innovantes proposées par des technologies de simulation numérique, comme celles développées par Ansys. Alex Lam, expert de ces questions chez Ansys, nous explique l'importance de la simulation numérique dans ce contexte où la durabilité des missions spatiales devient un impératif.
Hey :)
Over the past few weeks, I’ve been working on a satellite orbit tracking and collision detection project — and it’s finally live on GitHub 🚀

📆 2019 #ESA is "working to #automate the process of collision avoidance" https://www.cnet.com/science/esa-spacex-starlink-satellite-nearly-collides-with-european-aeolus-satellite
15/01/2025 "Improve #SpaceTraffic surveillance and coordination" still on the #ToDo list https://www.esa.int/Space_Safety/Technological_to-do_list_to_reach_Zero_Debris_created ... "This will ⏳ require compatibility of different #automated systems" https://esamultimedia.esa.int/docs/spacesafety/Zero_Debris_Technical_Booklet.pdf 🥱
Active #satellites 🛰️ must perform an increasing 📈 number of #collision avoidance manoeuvres to dodge out of the way of other satellites and fragments of #SpaceDebris. Another factor is the high level of solar ☀️ activity which can often cause increased atmospheric drag. If we extrapolate current trends into the future, catastrophic collision 💥 numbers could rise 📈 significantly https://www.esa.int/Space_Safety/Space_Debris/ESA_Space_Environment_Report_2024
