Arzachel Lunar Base

The Arzachel lunar base is the new Earth Alliance lunar base after the destruction of the Ptolemaeus lunar base in CE 71 and the headquarters of the EA space fleet. As its name suggests, it is located in the Arzachel crater. The EA launched its first attack on PLANT during the Second Bloody Valentine War from this base. In CE 74, the 8th EA Mobile Fleet was stationed here, and was instrumental in distracting the ZAFT forces during the Requiem superweapon attack on PLANT. However after Dullindal's speech of his Destiny Plan ZAFT used the captured Requiem weapon to destroy the base, killing the president of the Atlantic Federation in this process.

The crater is named after Al-Zarqali (in full Abu Ishaq Ibrahim ibn Yahya Al-Zarqali, "Arzachel" to Latin Europe), a leading Arab mathematician and the foremost astronomer of his time.
