Do we really know what goes on in space?

I was quoted by The Guardian newspaper last week in an article with the above name, in connection with Chinese launch and associated "propaganda". You can find the article here. The amateur satellite trackers I mentioned (who I would say are very talented, not fairly) are part of an informal international network who watch what is going on in space from the ground. If you would like to find out more about this, take a look at the Visual Satellite Observer's Home Page.
