Knowing little about design, I just wonder if rather than deploying cubesats fitted as ballast, a transponder could not be fitted to the hull of the appropriate vessel which contains the sats and ballast? It could also relay vibrations from the vessel as it tumbled in the sky and would therefore have some utility to launch provider? I think this approach was adopted by Aatis in Germany a few years ago.

I wonder does the SpaceX rocket hang around as debris for the next 25 years in a 600 km orbit or does it head back to the Earth and burn up ?

I don't know, does anyone ?
