We suggested this and hope they add it. There is a mod called bounty you might like, I think its in the Hanger Bay section. Not sure, or maybe API section, have a look.
It would be really great if one of the "visibility" properties for mission was, "Player on playfield:[Akua, Akua Orbit] etc..."
The ones in the game seem basic though they are good starter goals that gave me general idea of what to "do" in the game. Would like to see a more fleshed out campaign/story driven missions in the future.
