Operation Ghost Moon really feels like it is an in-world document for the agent which makes it feel like a fun prop to have handy at your table. The space race theme is a very on theme aesthetic for FIST in general and helps people get into the mid century mindset. It's a great scenario for creating theme appropriate inspiration.
As far as the content itself I had a hard time understanding how to run the the game even after reading it multiple times. The enemies for example have attack ranges measured in spaces. It isn't made clear up until that point that this module uses grid based combat and after reading everything I'm still not sure how I am supposed to use the map. If you are going to change the standards of play of a system in a module I think you have to make that very clear and take time to explain the mechanical changes clearly.
Also, as said before if the reader doesn't have knowledge of A Space Odyssey, this scenario offers more questions than answers. I think it would be beneficial to be more specific and less referential to make the scenario require less homework.
