The Pioneer mission to Venus consisted of two spacecraft, an orbiter and a multiprobe that entered the Venusian atmosphere, each of them launched separately. This is a model of the Pioneer Venus orbiter, which studied the planet for more than a decade following its arrival in 1978. The Pioneer Venus orbiter carried a radar altimeter, which was used to make the first global map of the surface elevations. Its main antenna was used to produce moderate-resolution radar images of the equatorial region.
