Space Situational Awareness

8 reports
Space Situational Awareness is a space-safety concept used to identify hazards, estimate risk, prevent failures, and plan operational responses. Understanding depends on collision risk, planetary protection, and launch abort, including the conditions under which a model, proof, or explanation applies.

The page treats launch abort, while also considering object tracking and collision probability as distinct parts of Space Situational Awareness. For questions involving object tracking, the account uses post-event analysis as the measured record and tracking catalogues to expose uncertainty; incomplete observations and uncertain orbits can limit risk estimates.
