Mariner 2 Anniversary Issue This computer-generated view of Venus shows the planet's topography, with the highest regions coded as red and the lowest as dark blue. The radar of the Pioneer Venus Orbiter provided the altimetry data from which this image was generated, and can also detect small-scale surface roughness. Rougher areas are coded as a white glint on this picture. Drs. James Blinn and Walter Brown, JPL
