The X-33 is an unmanned advanced technology demonstrator with a mission to validate new technologies ofr the next generation of Reusable Launch Vehicles.  Various system redundancies are designed in the X-33 to enhance the probability of successfully completing its mission in the event of faults and failures during flight.  One such redundant system is the Vehicle and Mission Computer that controls the X-33 and manages the avionics subsystems.
