Definition of "extra-vehicular"

“His venture into the vacuum of space began the history of extra-vehicular activity that makes today’s Space Station maintenance possible,” NASA said on Twitter.

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 .

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.

Conversely, the absence of detectable VGE is correlated with a very low probability of DCS in both hyperbaric or hypobaric settings, hence the development of pre-conditioning strategies that aim to reduce VGE production. Oxygen pre-breathing (OPB), a standard approach to remove dissolved N2 from tissues in anticipation of exposures to sub-normal pressures associated with high altitude aviation and extra-vehicular transits while in space, is one of those strategies .
