Space Situational Awareness
11 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.
