Space systems. Prevention of break-up of unmanned spacecraft1 Scope This International Standard defines the requirements to reduce the risk of in orbit break up of unmanned spacecraft, both during and after their operational lives. The aim would be met by reducing the possibility of a break up caused by an unplanned internally caused event and by depleting to a safe level all the sources of stored energy at the end of a spacecrafts life. This International Standard is designed for use in planning, verifying,
