This is a long shot. I read a book back around 2004. but the book could have been from the 80s or 90s. It was a sci-fi book. it said something on the cover about being made into a movie. But that hasn't ever helped me to find it. here are a few of the details I remember; the world is ending, the government is building a rocket in florida, another guy is building on in the dessert. there is a radical christian group in the story that tries to stop the rocket from launching. the idea of the rockets are like a noah's ark kind of thing to grow plants and have people live on as a society. I know, not much detail, and there are a TON of sci-fi books about the end of the world. and a lot of sci-fi movies based on books. has just always bugged me I could never remember the name of the book, and figured worth a shot.
