Creative Speculation

But I like to consider all possibilities. I'm thinking of how, with the exception of landing a man on the moon, the Russians beat us to pretty much every space landmark: first satellite, first man in orbit, first spacewalk, first woman in space, first space station.... Their technology is not to be belittled.

As for China, I don't think they're capable of building things like this. (I'm actually beginning to wonder if we are.... It's my opinion that the Space Shuttle program was a devastating sidetrack from space exploration. I think it was an outgrowth of Reagan's Star Wars fantasy, carrying more military payloads than scientific ones.)

But who knows? At this point, all we can do is try to learn as much about these objects as we can. And it appears that the Pentagon is on track with this.
