1: It's A Decent Starting System, 2: You Can't Really Recommission Much, You're Basically Starting Over, 3: Yes, Rather A Lot, (You're Starting At 'Average' Tech Instead Of 'Pre-Warp',) 4: 50 Basic Credits, 5: Undecided.

Over the First Month or so, your Orion Bots come to grips with the resources available to you, and they turn out to be both better and worse than you had expected. The first thing that becomes painfully obvious, is that you will not be able to reactivate most of the former colonial infrastructure, it was bombed into oblivion by the Anatarans. You manage to assemble a working Marine Barracks and get a crude Orbital Defense Platform / Shipyard put up in geostationary orbit over the central colony, but that's all.

Once that's out of the way, your scientists turn their eyes to the heavens and examine your star system: finding the following system features:

Staghorn Primaris: Main sequence Mishara-class Yellow-white dwarf star.
Staghorn I: Tiny (can only hold 1 population), Barren, Rich Minerals.
Staghorn II: your 'capital' world. Average Size, Terran, 8/12 population, Average Minerals.
Staghorn III: Small, Arid, (7 max population), low gravity, average minerals.
Asteroid Belt: uninhabitable.
Staghorn V: Gas Giant: uninhabitable.

Now, even as this is going on, your scientists are examining the population for useful scraps of technical data from the old Orion era and they come up with a treasure trove!

It seems nearly everyone remembers some useful tidbit of information which allows you to recover the following technologies: Electronic Computers, Freighters, Troop Transports, Outpost Ships, Colony Ships, Atomic Drives, Atomic Bombs, Atomic Missiles, Titanium Armor, Standard Fuel Cells, Extended Fuel Cells, Space Scanners, Laser Rifles, And Laser Cannons: basically, you're starting at an "average" tech level while everyone else will be beginning at "pre-warp"!

In terms of stockpiled resources, you have only about 50 Basic Credits, but, that's ok, you'll earn more.

And lastly, we come to your construction orders, to whit, you didn't give any, nor research orders either, now that you know what you already have it's time to decide what to work on next...
