Venera 15. 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.
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. The images returned by these ...
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]

In 1983, the Soviet Union launched the last two spacecraft of the Venera program, Venera 15 and 16. These missions were dedicated orbiters equipped with synthetic aperture radar systems, which allowed them to map and study the planet’s surface in unprecedented detail.

Jun 2, 1983 · The Venera 15 and 16 synthetic aperture radar (SAR) systems were identical, and were used to map the surface of Venus at a resolution of 1 to 2 kilometers (.6 to 1.2 miles) over a period of 8 months. Radar is necessary for Venus surface mapping because the planet is covered by an unbroken layer of thick clouds.

Venera 16 was launched on 7 June 1983 at 02:32 UT, five days after the Venera 15 launch. Launch took place from Baikonur Cosmodrome (Tyuratam) on a Proton-K booster. After two course corrections on 15 June and 5 October, it arrived at Venus and went into a 977.3 x 67,078 km altitude, 24 hour, 34 minute period orbit on 14 October 1983 at 06:22 UT.
