Astral Planetology - the use of Astral Projection to explore other worlds and how they work.
This is my entry for Seventh Sanctum's "Technomancy" contest. not doing 'for fun' this time, because, well, my competitive side is coming out for once.
So, when I spun the Wheel of Technomancy, the generator gave me Astral Planetology. So here's a person's Astral body floating around around Saturn.
