White Moon

From Galaxy Angel Wiki, the comprehensive Project G.A. reference.

The White Moon (白き月, Shiroki Tsuki^?) was one of a pair of defense satellites constructed for the protection of Juno, the homeworld of the EDEN civilization. It was administrated by the Moon Goddess Shatoyan. It did not possess the capability to mass-produce ships automated ships like it's counterpart, the Black Moon, but instead relied on a single carrier ship (the Elle Ciel), with a compliment of Emblem Frames, all of which required humans to pilot them. They were built with opposite philosophies: the White Moon's technology relied on the human spirit, believing in the infinite possibilities of humanity, while the Black Moon's technology was completely automated, wanting to eliminate the uncertainties that came with a human operator. The reason for doing this was to allow each moon to gain knowledge of the respective advantages and disadvantages of each extreme, and to eventually have the moons merge with each other to pool their experience and determine the best philosophy to go with for the defense of Juno. When the Valfask succeeded in conquering the EDEN civilization, the White Moon was able to escape, and wandered through space for the next 200 years, when it settled into orbit around Transbaal.
