Welcome to the Moon

Choose a common adventure sheet and one matching A, B and C mission. Multiplayer uses 63 shuffled Starship cards divided into three equal piles, number side up. Adventures work separately or through the campaign; apply each adventure’s exceptions alongside these standard rules.

In multiplayer reveal three number-action combinations each turn. Everyone independently chooses one, and several players may choose the same combination. Do not mix a number from one combination with another’s action. When piles run out, reshuffle each discard pile separately.

Write the chosen number in an empty legal space. Numbers ascend within each zone without duplicates, but gaps and skipped values are allowed. If none of the three choices can be written, mark a System Error and take no action; do not voluntarily reject a legal number.

Normally write first, then optionally use the paired action. Astronaut can adjust the value by zero, one or two before writing, in either direction but never below zero. Planning adds an X; multiple Xs are legal in one zone, and Xs count as filled spaces.

Robot, Energy, Water and Plant work as specified by the adventure. Water and Plant normally require writing in an appropriate position to use that action; otherwise you may still write a legal number. Ordinary actions are optional, with specific adventures such as the first changing this procedure.

Resolve incidents after actions and before missions. Claiming a qualifying mission is optional. All players first claiming it in the same turn receive its higher value; later turns receive the lower value. Each player completes each mission only once and keeps its award even if its condition later ceases to hold.

Standard end conditions are checked at turn end: all three missions completed, all System Error boxes used, or the marking area filled. Apply the adventure’s scoring and error penalty. Standard ties favor fewer crossed-off System Errors, then share victory.

Adventure one uses action symbols to restrict rocket floors rather than performing the six normal actions; its bottom floor is wild. The official FAQ requires crossing all rockets below the 150 box before clearing circled System Errors. Circling every error triggers the finish. Launching requires clearing every circled error too; simultaneous launches compare extra rockets.

ASTRA solo draws three Starship cards and uses two different cards for number and action, giving the third to ASTRA even after a failed placement. Resolve drawn effect cards immediately and replace them until you have three Starship cards. Solo bonuses can permanently discard a card instead of giving it to ASTRA.

On the first exhaustion reshuffle only your own discards and effect cards, leaving ASTRA’s cards out. Failure to draw three cards on the second exhaustion ends play immediately; other endings follow the adventure. ASTRA normally scores received action types plus fixed and difficulty values, but adventure one uses its special launch track instead.
