In 1978, the Pioneer Venus Multiprobe spacecraft was launched to study the planet Venus. The spacecraft consisted of four identical probes that were designed to enter the Venusian atmosphere and collect data on the planet’s conditions. The probes were equipped with a variety of sensors that measured temperature, pressure, composition, and other atmospheric parameters.
The Pioneer Venus Multiprobe mission was highly successful in gathering data about the planet Venus. The data collected by the probes has helped scientists to better understand the conditions on Venus and has also provided new insights into the evolution of planetary atmospheres.
