Here's my little list of suggestions for now, sorry but I couldn't come up with anything for research.
Construction
> Build Space Academy on Aries. This will teach human crews how to operate, pilot & maintain all varieties of military & civilian craft. Record lectures/lessons & illustrations on all relevant facts to display to students. Have the Scientist act as the first and primary faculty member, see if we have any others that might fit the position.
> Begin drafting designs for military vessels. I suggest starting with a 1-seater fighter craft armed with lasers or small mass drivers, and a frigate of the maximum size we can afford. Equip the frigate with docking clamps (bays might be too large for this small a ship) to haul the fighters when not in flight, and equip both ships with antennas -- we can use our aerotransmission to transfer power from the primary ship to the fighters even while they are in flight, only hope like hell it backfires and we end up with a bug zapper. Run that through extensive testing with robotic drones at our weapons testing facility before we commit to that plan; until then, use standard energy cells. We're probably going to be seeing 15-20 man crews for a 30 meter long frigate, to handle piloting/navigation/gunnery/sickbay/engineering and such all at once. We can put several turrets on them, either lasers, missiles or mass drivers as that's the most practical stuff we can field right now. I'll leave naming these ships up to you guys.

Manufacturing
> Design and manufacture some small arms, from low-yield sidearms to rifles. We want our guys able to defend themselves at this point, and also be able to field marines if it turns to boarding combat but let's start simple for now.
Actions
> Send a one-man shuttle or unarmed scout craft out to investigate the Moonies; if its just running on conventional drives and not reliant on external input it should avoid the notorious jamming problem that plagued our drones. We need to find out what the hell is going on; make sure the craft has a good communication device so we can talk to them once we get close enough. Give him orders to turn back if anything starts to look wrong, though.
> Allow the new colonists to touch down on Gaia; build a survival bunker to protect them for now, a compound or wall would make them feel trapped and oppressed. Send some Mavens down there for field testing as well as keeping order and assisting/protecting the colony, but NO GUNS. Have security bots maintain a perimeter around the colony as well, we can control them more reliably.
