Space Situational Awareness
8 reportsThe 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.
