Aug 26, 2020 · The Pioneer 12 probe may have been first to map Venus using radar, but Venera 15 and 16 did it better, reaching a resolution of about a mile (1 to 2 km) per pixel.
May 19, 2024 · Over the course of their eight-month missions, Venera 15 and 16 mapped approximately 25% of Venus’ surface, revealing a world dominated by vast plains, towering volcanoes, and intricate networks of tectonic faults.
Venera 15 (Russian: Венера-15 meaning Venus 15) was a spacecraft sent to Venus by the Soviet Union. This uncrewed orbiter was to map the surface of Venus using high resolution imaging systems. The spacecraft was identical to Venera 16 and based on modifications to the earlier Venera space probes.
The Venera (Russian: Вене́ра, pronounced [vʲɪˈnʲɛrə] 'Venus') program was a series of space probes developed by the Soviet Union between 1961 and 1984 to gather information about the planet Venus. Thirteen probes successfully entered the Venusian atmosphere, including the two Vega program and Venera-Halley probes.

The images had a 1–2 kilometres (0.62–1.24 mi) resolution, comparable to those obtained by the best Earth radars. Venera 15 analyzed and mapped the upper atmosphere with an infrared Fourier spectrometer.
