NASA knows that one of its massive satellites will crash to Earth, they’re just not sure exactly when or where. But don’t worry, NASA says the risk of harm is “low," but notably NOT ZERO. The space agency predicts the satellite will reenter Earth’s atmosphere at 7:45 pm ET, “plus or minus 24 hours” and says the chance of anyone being is harmed is approximately 1 in 4200… Not exactly reassuring!
