Excuse me, now on July 12, 2024, the urls in your code (http://www.celestrak.com/NORAD/elements/active.txt etc.) are no longer accessible, is there any way to crawl the historical TLE data from celestrak, if you know, you can let me know, thank you very much.

Hello @Rhett12345, this gist is pretty old and all the links have been probably changed since then, here is a quick documentation on the new way to obtain the TLE data from CelesTrak's website, also you can check SpaceTrack, it's well maintained, but somewhat restricted on the process of using their data in public projects.
