Here you can see three important parts that are needed to fly a spacecraft. On the left is the Lunar Reconnaissance Orbiter's avionics module, which contains the electronics used for communication and navigation. In the center is the propulsion module, which contains the spacecraft's fuel. On the right are the reaction wheels, used to change LRO's angular momentum and point the spacecraft in the right direction.
