The ship had been a test bed for a new phasing cloaking device developed by Starfleet Intelligence, and the ship's crew had mutinied in protest against the creation of such a device. In fact, the ship, still in a phased state, drifts through space, eventually dephasing inside an asteroid in the Devolin system. Following the Judge Advocate General's inquiry into the incident, William T. Riker is assigned to Betazed. (TNG: "The Pegasus")
