This is a replica of the Pioneer V satellite. The spacecraft was designed to send back scientific data on interplanetary space while in orbit about the sun. It was launched on March, 11 1960 and entered an orbit around the Sun between the Earth and Venus. Pioneer V provided a wealth of new data on interplanetary space including measurements of magnetic fields, cosmic radiation, electrical fields, and micrometeorites. It transmitted information until June 26, 1960, when it was 22.5 million miles from Earth. The replica was re-assembled by the program coordinator, Space Technology Laboratories Inc., from original parts that failed to meet flight specifications and donated by them in 1964 to the Smithsonian Institution. It was displayed at the Palais de la Decouverte in Paris from October 1970 until October 1975.
