Well it's classified, no one is SUPPOSED to know what is on it. Don't believe the Chinese nonsense about us creating a dangerous situation though, that is to distract everyone from the fact that THEY blew up a satellite a couple years ago, except they did it 500 miles up where it created a debris field that endangers spacecraft and other satellites. All the junk from ours will re-enter over the course of a month or so. What I'm hearing is that there's nothing bigger than a football left intact.
