An assessment of the feasibility of simulating the functionality of an autonomous spacecraft and its ground control system by enhancing a simulator and control system is presented. The distributed, hierarchical onboard architecture based on an earlier ESA study (the Standard Generic Approach to Spacecraft Autonomy and Automation (SGASAA)) is described. The architecture utilizes onboard tools for autonomous replanning and enhanced failure diagnosis. The ground control system is changed to enable onboard event reconstruction and the implementation of the autonomous spacecraft simulator is changed to reveal changes in the ground based mission support role.
