The moon provides the ability to spy on other's fleet movements through the use of the Sensor Phalanx. Also, certain fleet operations can be masked from other moon's phalanx when your fleet is sent from the moon.

DF is Debris Field. It is the residual resources left floating aorund a planet after an attack has occurred. It can be recovered for re-use by using a Recycler.
