CASUALTY RISK FROM THE UNCONTROLLED REENTRY OF ROCKET BODIES AND SATELLITES
2022
The current cumulative annual global casualty expectancy for uncontrolled reentries of spacecraft and orbital stages is of the order of 0.01. Hence, the corresponding individual risk is still extremely low, if compared with the hazards commonly faced in the everyday life, with a probability of being personally injured of the order of 1 in 800 billion per year. However, this risk is increasing, due to the rapid growth of space launch activities and to the rise in world population. Moreover, ...
