The Pioneer Venus program encompasses two spacecraft missions, Orbiter and Multiprobe, to be launched and to encounter Venus during the 1978 Venus mission opportunity. The missions are described in detail including mission and spacecraft descriptions, scientific objectives and payloads. The ways in which the payloads address the major scientific questions concerning Venus are treated in subsequent papers.
