Satellite operators currently have no independent means of verifying the structural condition of their spacecraft after launch. Pre-launch MMOD risk assessments are computed from manufacturer-supplied CAD models and never updated by in-orbit measurement. Once on orbit, visibility into cumulative micrometeoroid and orbital debris (MMOD) damage is limited to whatever telemetry the satellite...
