[x] Global Cooperative - You take control of the Global Space Agency. Thanks to an unprecedented bit of cooperation, the Internationale/UN/etc. have decided to pursue a global space program and the countries of the world have agreed to provide you funding. Here you will deal less with outside actors (because everyone agreed to fund you) and more with juggling the political support to keep their support.
[X] Bipolar World - You take control of one of two agencies, beholden to a pair of opposing superpowers, in a race to demonstrate your nation's technological dominance in the field of spaceflight. You will have great resources at your disposal, and relatively few demands on how you complete the objectives given to you by your nation's political establishment - only that you do complete them and one-up The Enemy. There are limited opportunities for cooperation and a political cost to attempting to do so, though it may be possible if you're willing to make that sacrifice.
[X] Multipolar World - You take control of one of four agencies in a world where multiple competing nations or national groupings have emerged (like the EU, or a very-early African Union). There are more political interests at play here, but there are also more opportunities for cooperation and international initiatives - provided one bloc or another doesn't, say, declare war on someone. Then things might get messier.
