yt-dlp works on nasa plus streams to rip them to your drive, i've grabbed what i can before it disappears, would appreciate some redundancy, please help archive this
yt-dlp can be found here:
github.com/yt-dlp/yt-dlp

https://plus.nasa.gov/video/the-color-of-space-a-nasa-documentary-showcasing-the-stories-of-black-astronauts/
If you want to grab the stream, play a video and right-click it -> Inspect. It will bring up a developer pane with source code for the page with the video element already highlighted. Expand by clicking triangle, the URL you want ends in .m3u8, copy it out and use that with yt-dlp
This is in firefox, I don't use chrome but it also has an equivalent developer feature, so adjust as needed
