The National Aeronautics and Space Administration (NASA) is developing an architecture for communication, navigation, and time distribution to support the future human exploration of space. Foreseeable applications span a wide range of demands for time services, including event logging by robotic and human explorers, networking of cooperative elements on a planetary surface, time transfer for navigation, and time synchronization and correlation for communication and science. This paper describes the key attributes of a flexible approach designed to meet those demands.
