The turn-based game offers campaigns to the moon and sandbox modes for the United States, Russia, and an international alliance. Online multiplayer is also supported using Slitherine’s asynchronous hosting system. The interface lacks tool-tips, does not indicate previously completed missions, and can make it difficult to find specific information quickly. Prestige points earned from attaining milestones increases the budget used to start a variety of programs, research rockets and payloads (probes, crew craft, spacesuits), and pay salaries. Personnel can be assigned to research specific components and increase reliability, or assigned to advanced training to increase their stats. Building upgrades are purchased to support more people, and random events can mix things up. Tense mission briefings incorporate technical issues, solved by assigning the best people to important roles. While the interface is lacking, the historical nature and flexibility (in terms of what can be done next) of Buzz Aldrin's Space Program Manager make it a solid management simulation.
