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]
Venera 4V-2 (Russian: Венера 4В-2) was a series of two identical spacecraft sent to Venus by the Soviet Union, consisting of Venera 15 and Venera 16. [1] Both uncrewed orbiters were to map the surface of Venus using high resolution imaging systems. The spacecraft were identical and based on modifications to the earlier Venera space probes.
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 7 was the first lander overall and first for the Soviet Union, touching down on 15 December 1970. Pioneer Venus 2 contained the first spacecraft to land from the United States, the Day Probe. It soft landed on 9 December 1978.
Venera 14 (called Venus 14 in English) was a probe in the Soviet Venera program for the exploration of Venus. Venera 14 was identical to the Venera 13 spacecraft, built to take advantage of the 1981 Venus launch opportunity. Venera 14 was launched on 4 November 1981 at 05:31:00 UTC, five days after Venera 13 launched on 30 October 1981 at 06:04 ...
Venera 4 (Russian: Венера-4, lit. 'Venus-4'), also designated 4V-1 No.310, was a probe in the Soviet Venera program for the exploration of Venus.The probe comprised a lander, designed to enter the Venusian atmosphere and parachute to the surface, and a carrier/flyby spacecraft, which carried the lander to Venus and served as a communications relay for it.
The spacecraft also carried a medallion bearing the State Coat of Arms of the Soviet Union and a bas-relief of Lenin to the night side of Venus. Given the results from Venera 4, the Venera 5 and Venera 6 landers contained new chemical analysis experiments tuned to provide more precise measurements of the atmosphere's components. Knowing the ...
Venera 7 (Russian: Венера-7, lit. 'Venus 7') was a Soviet spacecraft, part of the Venera series of probes to Venus . When it landed on the Venusian surface on 15 December 1970, it became the first spacecraft to soft land on another planet and the first to transmit data from there back to Earth .
