The Venera-D (Russian: Венера-Д, pronounced [vʲɪˈnʲɛrə ˈdɛ]) probe is a proposed Russian space probe to Venus, to be launched around 2026. Venera-D's prime purpose is to make radar remote-sensing observations around the planet Venus in a manner similar to that of the Venera 15 and Venera 16 probes in the 1980s or the U.S. Magellan in the 1990s, but with the use of more-powerful radar. Venera-D is also intended to map future landing sites. A lander, based on the Venera design, is also planned, capable of operating for a long duration (24 h) on the planet's surface.
The "D" in Venera-D stands for "dolgozhivushaya," which means "long lasting" in Russian. Venera-D will be the first Venus probe launched by the Russian Federation (the earlier Venera probes were launched by the former Soviet Union). Venera-D will serve as the flagship for a new generation of Russian-built Venus probes, culminating with a lander capable of withstanding the harsh Venerian environment for more than the 1½ hours logged by the Soviet probes. The surface of Venus experiences average temperatures of 462° Celsius (864 Fahrenheit), crushing 90-bar pressures, and corroding clouds of carbon dioxide laced with sulfuric acid. Venera-D will most likely be launched on the Proton booster, but may be designed to be launched on the more powerful Angara rocket instead.
