Astronomers use fisheye lenses to capture cloud cover and light pollution data. Photographers and videographers use fisheye lenses so they can get the camera as close as possible for action shots whilst also capturing context, for example in skateboarding to focus on the board and still retain an image of the skater.
Why does NASA use fish eye lens?
The reason why they use fisheye lenses in space is because this type of lens has a super wide field of view and a large depth of field (DOF) and this means that whoever monitors space are unlikely to miss anything.
