There need to be better mission descriptions in the manual. The Mission Description section contains vague notes about some of the mission requirements, but very little about what they actually entail.

Some of my concerns:

• There's a brief mention of the (Orbit) descriptor in the Docking Module section, but it should be (re-)referenced in the Mission Description section. It's described only once, briefly, and is confusing to novice players.
• What is an Orbiting Lab? What steps are involved?
• There are two missions named Joint Manned Orbitals Docking EVA Duration (30 & 35).
• What does it mean that Joint Manned Lunar Orbital: LOR (47) is a joint mission? Why is it joint? What's the difference between it and Manned Lunar Orbital (46)? (Note: In-game it is referred to as an EOR).
