Abstract
Project Helios is the first NASA international deep space project—although there have been prior NASA international sub-orbital and earth-orbiting cooperative space projects. Helios is a joint undertaking by the Federal Republic of West Germany and the United States of America, who divide the project responsibilities. Two unmanned scientific satellites are planned for heliocentric orbits—the first to be launched in mid-1974, and the second in late 1975. Prior volumes of this series describe the history and objectives of this program, the contemplated spacecraft configuration, and its telecommunications and telemetry systems, This article deals with the spacecraft’s command system, its requirements, and conceptual block diagrams.
