The Pioneer Venus Multiprobe was a NASA mission launched in 1978 to study the planet Venus. It consisted of three components: an orbiter and two atmospheric probes. The mission aimed to gather data on Venus's atmosphere, surface, and overall environment, providing insights into its composition and weather patterns. The two atmospheric probes, named Pioneer Venus Atmospheric Probe and Pioneer Venus Daytime Probe, entered Venus's atmosphere and transmitted valuable information back to Earth. The mission significantly advanced our understanding of Venus, revealing details about its thick clouds, high temperatures, and pressure, which are crucial for comparative planetology.
