That’s the way it looks. It doesn’t explicitly say that the “Co-Operate” action is removed from the game, but, Stations p. 22:
There is exactly one type of trade that may involve a non-trading agency: a non-trading agency may give money to a trading agency in exchange for a joint venture share. That is the only type of inter-agency trade that non-trading agencies may participate in.
(And a non-trading agency is any national agency that has no joint venture shares. If you do have a JV share, you can trade with anyone, not just fellow partners in that JV)
Incidentally I’ve updated my rulebook with the rocket tables and purchasable item list; link in the first post.
I’m exactly replicating my last turn, see what succeeds etc.
(Reminder: Okey doke, let’s show y’all how it’s done. One Atlas, one Soyuz, two juno. Junos on the atlas and launch the atlas/ Juno and Soyuz (on its own). If both successful I’ll fire the HR guy and pay off the Atlas. Otherwise pay off both.)
Apologies for the confusing Juno shenanigans. I was getting mixed up between Earth orbit as suborbital. Was planing to fire the Junos back down to test re-entry, oops. I’m slowly remembering how to play…
Updated rules PDF. It now has an appendix with manoeuvre tables for standard rockets and ions, the full purchasable item list, and transfer windows (both when they’re available and which ones you can chain).
Might as well fire off the last Juno. If it’s success then I’m basically counting that as that we’ve got it right and no need to worry about further testing. Pretty sure the maths agree with this perspective.
