I think that there is enough complicated items in the game that we have to simplify how and what constitutes "Space Units".
So... Here's what we've come up with as Research Items in the game.
1) Weather Satellite
2) Communications Satellite
3) Lauch Pad
4) Reconnaisance Satellite
5) STAR WARS!
Weather Satellite (assuming Weather Still stays in the game). Once this item is researched, the World Market will launch it for you as long as you are a member.
Communications Satellite - May or may not be includedâ€¦ (Should give a boost to Unit Response since this benefits your Command and Control Structure.) Will give a boost to Domestic Approval (population gets more TV channels
) Again, once you have this researched the WM to launch it for you as long as you're a member.
Launch Pads - Separate Tech Item that has to be researched before it can be built. (If you have a Launch Pad - you don't have to be a World Market Member to have Weather and Communication satellites launched.
Reconnaisance Satellite - Once researched, this would require you to have your own Launch Site (NOT ICBM Silo). When you click on the hex that has the launch site, it tells you the status of you recon satellites...
Star Wars Technology --- Requires Launch Site (NOT ICBM Silo).
Once researched, it starts launching protective satellites. When you select the Launch site hex, then it will report Recon Satellite status AND confidence in Missile Intercept.
That's about it... Other than Building a Launch Pad once the research is complete, everything is generally automatic.
