When a probe like Voyager 1 is sent into deep space they are able to point the camera at the planet and its moons and take pictures.
- How is the camera pointed at the object?
- Is the camera fixed to the probe or do motors orient the camera independently?
- Do they know the exact position of the probe with respect to the planet and pre-program orientations and exact times to take pictures?
- Is there something on board to point the camera at a close gravitational mass of some kind?
- Some other sensor to orient the probe? Light or infrared? How do they make sure it doesn't get confused by the sun?
