Looks like removing the xfail_skyfield_unstable_numpy2 decorator reveals some incorrect imports and unnecessary TLE download. I'll see if I find a simple fix for those to be included in this PR.

Should this maybe have the backwards incompatible and enhancement labels added to it? I don't think "dependencies" alone will make it show up in the changelog.
