Today we're talking rotational stability and Artificial Gravity! This video has been a long time coming, and not just because it took 47 hours to edit, I took my first pass at this script about a year ago but wasn't sold on the final product. A very busy year later I've finally decided to cut the video down to a (slightly) more simple discussion about rotational stability in the context of artificial gravity. Nevertheless, this ended up being my longest science video ever, and definitely one of the most taxing for my ten-year-old computer. I think these are some of the best visuals I've done even though they are still fairly simple, but there is still so much to talk about. I did a lot of research for that first draft, including how you can perform maneuvers while spinning, and even a way to jumpstart the rotation using gravity gradient stabilization. Enjoy!
