New Trilogy: Project Tor

Starting with ideas I have drawn from a recent movie I saw and wrote about – Island of Terror – the trilogy of Project Tor as born. Right now, I have one adventure worked out but not sure where else it can go.
The first adventure has the Asteroid Psyche vanish and reappear in the relatively same orbit 47 days later. It obviously went somewhere and what they theorize is that there is some kind of Reich experiments on interstellar travel being conducted on the asteroid.
I think this can grow into a all out prevention of an invasion from an alien force, but we will have to see.
