Earth is not overrun with TITANs, but it's politically convenient for the higher authorities who are virtually immortal to claim it is. And blow up any attempts to communicate otherwise. Not to say TITAN activity is at zero, but when they left on the Pandora Express, all the concentrated effort did, too. I'm thinking the initial hook will be a small event on a small to moderate hab and a "erroneous" mass driver strike, with the players maybe/not getting off in time with a small window. But I'm having trouble establishing what or who would give them that window. Ideas?
