[amsat-bb] DirecTV races to decommission broken Boeing satellite before it explodes

[Alan]

Dan,

There is a reasonably accurate discussion here:

https://en.wikipedia.org/wiki/Graveyard_orbit

Note toward the end the section on dealing with the disposal orbit slowly filling up.  I have seen references to companies looking at the economics of pickup and disposal for dead satellites.  No idea where that stands, however.  There are a few from the earliest days of the Space Age which would be great to have in a museum.

73,

Alan
