The frightening part is that, in addition to disrupting normal communications in vehicles, they also enable malicious listening in order to obtain sensitive and valuable data. However, these valuable data are generally localized in practical applications and divided into asymmetric and symmetric data distributions. Examples include symmetrical relationships between data from extra-vehicular networks and asymmetrical probability distributions of malicious and normal network traffic [10].

Recognizing the time demands associated with executing pre-operations planning and struggling to meet increasing call for extra-vehicular robotics operations on-board the ISS, NASA’s Robotics Operations branch sought to automate their pre-operations planning process with the goal of decreasing process execution time while preserving (or ideally, improving) the process’ level of safety and mission success.
