ESAs 5th cornerstone mission BepiColombo to the innermost planet, Mercury, serves as an example and case study
for an interplanetary spacecraft that has to operate in a particularly harsh environment. After decades of development
and seven years of ight time, there will only be one year of nominal scientic mission, as is common for highly complex,
scienti
c space probes.
To ensure the maximum scientic bene
t within this limited time frame in the future, a high level of on-board autonomy
would be bene
cial to avoid unnecessary safe mode events and ensure safe mission continuation even in case of no link
to ground. By means of this simulation and testing concept, the increasing resilience by enhanced self-awareness of
the spacecraft in the fault management domain on system level is demonstrated. The work to be presented introduces
the respective simulation concept, its set-up and demonstrates its possibilities. For simulation purposes, a test concept
is introduced that features a goal-based mission continuation strategy with eight levels of increasing complexity and
fault/failure scenarios implemented in a cognitive recovery unit. The simulation consists of three parts, each of which
will be presented: the system simulation of all relevant spacecraft subsystems, the independent goal-based mission
continuation knowledge base and processing as well as the graphical user interface to introduce faults and failures and
control the simulation process. First achievements of the simulation and considerations for future developments conclude
the paper.
