If the satellites had collided, there is a risk their debris would have set off a chain reaction, destroying other spacecraft and polluting orbit with hazardous space junk.
The companies were informed of a possible collision by the US Space Force’s 18th Space Control Squadron, which predicted a 1.3 percent chance of disaster.
OneWeb’s engineers quickly got in touch with SpaceX by email, to help manoeuvre the satellites out of the way.
Chris McLaughlin, chief of government affairs at OneWeb, told The Verge SpaceX flipped the switch on Starlink’s AI-powered collision avoidance system, effectively allowing OneWeb to move its satellites out of harm’s way.
