Hacker News Comments on
The International Space Station's Accidental Spin Visualized

Scott Manley · Youtube · 4 HN points · 2 HN comments
HN Theater has aggregated all Hacker News stories and comments that mention Scott Manley's video "The International Space Station's Accidental Spin Visualized".
Youtube Summary
NASA makes data available from the international space station, which means that when Nauka took the rest of the station for a spin we had telemetry. A few people have tried to produce visualizations of the spin, but I think many of these are wrong because they're trying to translate the rotations using Euler angles which run into singularities near the poles, and the spin carried them close to these regions.
The correct data source would be quaternions which don't suffer from singularities, and are available from ISS data sources.

Scott Manley's video[0] is interesting because he (among others) realized that the rotation was way more serious while the official 45° rotation story was still the news.

That video is really sped up.

Scott Manley's explanation of the ISS accident also introduces quaternions as a coordinate system for objects in space that solves the gimbal lock problem and has other desirable algebraic properties:
