Is this related to our super-secret moon base we have there? I never did follow the reasoning behind all of that.

Apparently, yes. Remember when the Shuttle remained in space for an extra few days to check for maintenance issues? Well, apparenly that "space walk" was a video taken elsewhere (probably the same set where they faked the original moon landing), while the real shuttle flew to the base, landed, offloaded the nuke, took on some fuel, and zipped back to earth before we were any the wiser. Must be Karl Rove again, directing camoflauge for his eeeevil plot.
