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

#USSPACECOM deputy cmdr, Lt Gen John Shaw at @ascendspace on Russian DA-ASAT test: We are still characterizing this event. We expect the debris will grow over time. #Perigee, #apogee event will widen. "It will become a threat that we will have to deal with." #ASAT #Russia
Shaw: This isnt' the beginning of such activity. #Russia conducted a similar test in April, though it didn't target a #satellite. Russia is showing "disregard of the sustainability of #space."
Shaw likens tracking objects in #space to book version of #JurassicPark: Scientists had automated sensors to track dinosaurs & algorithm to count the expected number of dinos. Problem is, it didn't account for the population of dinos rising. ...
1/ (THREAD) Ok, short thread rounding up what we know so far on the #Cosmos1408 breakup, potentially as a result of a Russian ASAT test
2/ A breakup event for Cosmos 1408, a derelict Russian ELINT satellite, was initially reported by @US_SpaceCom in @HoustonChron
3/ Breakup was confirmed by @LeoLabs_Space, and at this point is only a few to couple dozen objects
