Before and after Venus flyby, Venera 11 and Venera 12 yielded detailed time-profiles for 143 gamma-ray bursts, resulting in the first ever catalog of such events. The last gamma-ray burst reported by Venera 11 occurred on January 27, 1980. List of flight platform instruments and experiments: [7] 30–166 nm Extreme UV spectrometer
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.
Venera 4's battery ran out while still slowly floating through the massive atmosphere, and Venera 5 and 6 were crushed by high pressure 18 km (60,000 ft) above the surface. The first successful landing on Venus was by Venera 7 on December 15, 1970 — the first successful soft (non-crash) landing on another planet, as well as the first ...

Vega mission description. The Vega program (Russian: Вега) was a series of Venus missions that also took advantage of the appearance of comet 1P/Halley in 1986. Vega 1 and Vega 2 were uncrewed spacecraft launched in a cooperative effort among the Soviet Union (who also provided the spacecraft and launch vehicle) and Austria, [1] Bulgaria, France, Hungary, the German Democratic Republic ...
