Astro-naut's Orbital Airstrip was a protected sanctuary and laboratory. A place for intense, focused scientific development, and equally important, maximum privacy from interlopers, especially those suffering from narrow minded government greed.
There is technologies of all sorts, developed by Roy Vigil a visionary way ahead of his times. A transporter is used for "beaming" to and from the Earth's surface. Airships built here that can travel great distances, some that can bend space to venture to distant star systems without bumping into the problems associated with mere light-speed mechanics, or the pesky limitations of Theoretical Relativity. There's an atmo-gravitic field to maintain an atmosphere, generate heat, and perhaps is the domed device you see pictured, providing low level shielding against meteors and other small cosmic debris pulled in by earth's gravitational forces.
- It appears to be an asteroid of fairly significant size. It should be visible from earth, unless some other technology is hiding it from view.
- No doubt it was traveling in a long transit period out past the gas giant planets, until it was captured and forced to stay near earth. If placed in a stable orbit(and it probably was knowing who we are talking about), it is likely still up there. The big question to ponder, is he?
