I would be honestly intrigued but wary of just the usual Elon bad/good so all things he does bad/good narratives.
If we are on the brink of Kessler Syndrome in LEO I would expect market pricing to reflect that.
I'm not sure we're coming out ahead on that one, but leave it to a guy who can detect things light-years away to be able to find a silver lining
Reminds me that scientists can use GPS to track earthquakes indirectly as it is interacting with the ionosphere: https://link.springer.com/article/10.1186/s40623-025-02211-y
There is a fair bit of statistical rigour described in the original article at : https://www.spaceweather.com/starlink/starlink_drag_explaine...
You can do some rudimentary localization by latitude, however, by comparing satellites in different inclinations. You also get data by altitude, of course.
Something like this: https://en.wikipedia.org/wiki/GOCE
Easier to look at the altitude loss and infer the acceleration indirectly. With access to the raw higher time-resolution altitude data, mapping should be possible.
SpaceX has in the past gone above and beyond to expose TLE data for scientists and astronomers[1], so it's possible that people inside SpaceX would be open to collaborating on such a project.
