is a time slider possible?

[wchristian]

With such a proliferation of objects it would probably be interesting to see when they popped up. The data doesn't seem to have an age or first date. Can that be obtained?

You could modify the backend script that updates TLE.json to pull the launch date of the objects from space-track.org (reference the satcat). You could then make a new set of groups that divide the catalogue by decade launched (ie. after 1950, after 1960, etc).

That doesn't solve the issue, but it is possible.
