[Update: The two satellites have narrowly missed each other, the AFP reports.]
Two inactive satellites orbiting Earth may collide high above Pittsburgh tonight at 6:39 p.m. EST. The odds of a collision, recently pegged at 1 in 100, now sit at 1 in 20, according to LeoLabs, a company that runs a ground-based radar array that monitors collision risks for objects in low-Earth orbit.
