On Monday, for the first time, we performed a set of manoeuvres to avoid a high-risk collision w. #SpaceDebris created in the #Cosmos1408 anti-satellite test last year.
This was a difficult #CollisionAvoidance manoeuvre.👏👏to our #Sentinel1A Control Team & Space Debris Office

#CollisionAvoidance monitoring is unfortunately routine work at #MissionControl, and our teams are well-practiced in reacting to high-risk events.
This near head-on #collision was however unique; the situation evolved rapidly, was tricky to avoid, AND we had <24 hrs warning

Sentinal-1A, part of the @CopernicusEU Sentinel-1 radar observatory providing day-and-night images of Earth’s surface, had its orbit altered by 140 m in order to prevent collision with a debris fragment ~several cm in diameter

2/🌏#Earth is surrounded by a constellation of tens of thousands of #satellites in orbit, but also of billions of #spacejunk of more or less large size, fragments coming from rockets or satellites, travelling at a very high speed: important risks of #collision.
3/💥#Kessler syndrome: we are rapidly moving towards a tipping point where the volume of space debris in low orbit is such that collisions are frequent, generate other debris and exponentially increase the probability of collisions.

2/ 🌏La #Terre est entourée d'une constellation de 10n de milliers de #satellites mis en orbite, mais aussi de milliards de #DechetsSpatiaux de taille +ou- grande, des fragments issus de fusées ou de satellites, évoluant à une vitesse très élevée: importants risques de #collision
3/ 💥Syndrome de #Kessler: nous nous dirigeons rapidement vers un seuil critique où le volume des débris spatiaux en orbite basse est tel que les collisions sont fréquentes, génèrent d'autres débris et augmentent de façon exponentielle la probabilité de collisions.
