The game is designed to challenge players by testing their knowledge on a variety of information bases related to the U.S. space program. The object of Mission Commander is to complete a lunar mission without losing your ship (or the lives of your crew). Players maintain their missions, their equipment and their lives by accumulating and conserving energy along the journey. Energy is gained through the accumulation of energy points, which are earned by answering questions during the mission. Questions are provided by a deck of playing cards which are placed on the board prior to the start of each game. As a general rule, correct answers to questions gain energy, while incorrect answers will lose energy. The first player to complete his or her mission with the minimum required amount of energy points wins the game.
