Resumen
Space is a harsh place for humans and electronics due to vacuum, extreme temperature ranges, enhanced radiation levels, and the micro-gravity environment.
To survive that harsh environment, engineers and managers use statistics to inform their designs and decisions. From the probabilistic definition of the space environments that surround the vehicle, through the estimation of the forces and torques required for attitude control, and even to the higher levels of management to evaluate and control risks, statistics plays a key role in mission success. This article focuses on the latter application, that is, the utility of statistics for assessing and managing project risks.
The non-existent or very limited maintainability of the systems operating in orbit as well as the criticality of these systems make risk management not only a necessity but a priority.
