It technically is always falling. ISS is in a low enough orbit that the very thin atmosphere there slows it down slowly and without regular thrust to maintain orbit would decay back to earth. It blew my mind when I learned how far out the atmosphere goes (like individual molecules, not thick air, just enough to gradually slow down orbits)
