Choose Shuttle tiles in reverse current turn order. After everyone chooses, turn order is reset in ascending order of the chosen Shuttle numbers; the player with the lowest number goes first (p. 4).

Yes, if you do not have a structure in an activated sector, you must pay the indicated Credits to the player who has the biggest structure there. Activating every sector in the row is mandatory, so you cannot use a slot if you cannot afford all required payments (p. 4).

You may build one Solar Panel per turn, at any time while performing a Command action, by spending 1 Rare Earth. You cannot build one while the Energy marker is on either of the two rightmost spaces; Energy must first be spent to move it back (p. 5).

An Engineer triggers a Corporation-token bonus after building, a Technician grants one Corporation action after funding a Project, and a Scientist lets you take an Astronaut from the Lunar Gateway after resolving the Command action. The bonus is based on the Astronaut deployed, not on the type of Command action itself (pp. 6–8).

During Maintenance, retrieve crater Astronauts, collect Corporation, Dome, and Headquarters income, pay Reputation and structure maintenance costs, and remove Astronauts from the Command area. For each missing Credit, move your Reputation marker back one space; if it would go below 0, lose 2 VP for each remaining unpaid Credit (pp. 9–10).
