I'm wondering,that's all.What's this Arzachel place that Djibril said to the Commander of the EAF moon base before escaping?Is it another LOGOS fortress?

And i think the Archangel won't be alone in the space war...Cagalli said the Archangel is in the 2nd Orb Space Fleet,so i assume that the 1st Orb Space Fleet is also up there as well?Might be the Kusanagi leading it.And i would like to know why Orb can maintain space fleets when they don't have any space bases.And they should have new space MSs to replace the Murasames,since think the Murasame does well only in atmosphere
