Hmmm, I dont know that there is any set way of doing particular scenes viewpoints! - only logical things like, if you want a scene to appear immense and looming, make it big first, and place the camera low to the ground and looking up a bit! - space scenes benefit from finding a viewpoint that shows great scale and distance, creating a feeling of floating or vertigo even, but that depends on where the objects are placed really!! - I always try to go for cinematic effects, might be a good for you to find a book on cinematography as a reference!? - another tip to help you 'find' that perfect viewpoint, use the directors camera! - its far more versatile!
