The Venera-D ( Russian: Венера-Д, pronounced  [vʲɪˈnʲɛrə ˈdɛ]) probe is a proposed Russian space probe to Venus, to be launched around 2026. [3] [2] [4] 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. [3] 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.

History

In 2003, Venera-D was proposed to the Russian Academy of Sciences for its "wish list" of scientific projects to be included into the Federal Space Program in 2006–2015. During the formulation of the mission concept in 2004, the launch of Venera-D was expected in 2013 and its landing on the surface of Venus in 2014. [5] In its original conception, it had a large orbiter, sub-satellite, two balloons, two small landers, and a large, long-lived lander (24 h). By 2011, the mission had been pushed back to 2018, and scaled back to an orbiter with a subsatellite orbiter, and a single lander with an expected 3-hour operation time. [6] By the beginning of 2011, the Venera-D project entered Phase A (Preliminary Design) stage of development. Following the loss of the Phobos-Grunt spacecraft in November 2011 and resulting delays in all Russian planetary projects (with the exception of ExoMars, a joint effort with the European Space Agency), the implementation of the project was again delayed to no earlier than 2026.
