Osterman worked there for only a short amount of time before an accident occurs that seemingly killed him: he was trapped in the chamber of the Intrinsic Field Subtractor and obliterated when the door cannot be opened and the program cannot be overridden. Soon after, sightings of various ghostly bodily systems (circulatory, muscular, nervous) are reported by the staff, leading to rumors of the base being haunted. One day, while Slater and Weaver still mourn the loss of their friend, Jon reveals himself reborn as a superhuman being with extraordinary powers.
The base was later swept by a devastating fire and is officially shut down. As Dr. Manhattan, Osterman paid the site one last visit, finding the picture of himself and Slater amongst the remains. He then teleported himself to Mars as part of his self-imposed exile.
