| Description | Four Pioneer Venus Probe spacecraft entered the Venusian atmosphere on December 9 1978, and descended to the surface while making in situ measurements of chemical composition, structure, and radiative balance. In the lower Venusian atmosphere, a number of anomalous events were noted in some of the scientific instruments and Probe engineering data. Many of these anomalies occurred on each of the Probes at approximately the same altitude. The anomalies are thought to be the result of some unexpected electrical interaction between the Probe and the Venusian atmosphere. This conclusion is based on analysis and testing of similar Probe hardware on the ground. However, the possibility that some anomalies were a result of latent design of manufacturing flaws cannot be ruled out. |
