Venera 8 (Russian: Венера-8 meaning Venus 8) was a probe in the Soviet Venera program for the exploration of Venus and was the second robotic space probe to ...
Venera 4 was the first successful probe, and showed that CO 2 is the main component in Venus' atmosphere. [15] [5] Venera 7 found the temperature and pressure data as well as the atmospheric composition. [5] [16] Venera 8 measured the K, U, and Th on the surface through gamma-ray analysis. [5]
From 1961 to 1984, the Soviet Union developed the Venera probes for surface mapping by radar. The Venera 4 (on October 18, 1967) was the first lander to make a soft landing on Venus (also the first for another planetary object). The probe operated for about 23 minutes before being destroyed by the Venusian atmosphere.
[36] [37] Venera 7 remained in contact with Earth for 23 minutes, relaying surface temperatures of 455 to 475 °C (851 to 887 °F), and an atmospheric pressure of 92 bar. [38] Venera 8 landed on July 22, 1972. In addition to pressure and temperature profiles, a photometer showed that the clouds of Venus formed a layer ending over 35 kilometres ...
Russian space science plans include the launch of the Venera-D (Venus-D) probe in 2029. [111] The main scientific goals of the Venera-D mission are investigation of the structure and chemical composition of the atmosphere and investigation of the upper atmosphere, ionosphere, electrical activity, magnetosphere, and escape rate.

Zond 3MV-1 No.2 [3] (or No. 4A [4]), also known as Venera 1964A in the West, was a Soviet spacecraft, which was launched in 1964 as part of the Zond program. Due to a problem with its carrier rocket third stage, it failed to reach low Earth orbit .
Beta Regio is a region of the planet Venus known as a volcanic rise.Measuring about 3,000 kilometres (1,900 miles) in extent, it constitutes a prominent upland region of Venus centered at
DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) is a planned mission for an orbiter and atmospheric probe to the planet Venus.Together with the separate VERITAS mission, which will also study Venus, it was selected by NASA on June 2, 2021 to be part of their Discovery Program.
