Purpose of the Standard ISO Standards System Safety Risk Management Commercial Company (manufacturers, operators, and customers) Launching Country If not, by Voluntary Activities Risk Management to Prevent Causalities Management Plan Safety Assessment of Risk Reduction Casualties on the ground 3
Re-entry risk management Safety Program Organization to perform safety functions Safety programme plan Review System Safety activities 4
Assessment of risk caused by re-entering debris Probabity of Risk Realization Estimation of Risk Casualty limit Risk Senarion and Consequence of Effects Approved Analysis tool and data for survivability determination Imposed by Government or self-restriction Assessment flow 5
START: Survivability Analysis Complete Demise completely demised or survived? Survive > threshold Risk on Human : Threshold < threshold >threshold Effect on the Earth Environment : Threshold <threshold Is the risk reduction possible by design change? possible Impossible Disposal by Natural Decay or Reduction of Orbital Lifetime (uncontrolled re-entry) Controlled Re-entry Design Change Risk Assessment Flow and Disposal Planning 6
Risk reduction measures Option for Risk Reduction Controlled re-entry Structural design to reduce survivability Notification 7
