High Altitude Venus Operational Concept (HAVOC) was a proposed set of crewed NASA mission concepts to the planet Venus. All human portions of the missions would be conducted from lighter-than-air craft or from orbit. [1] A similar concept, the "Floating Islands of Venus", was proposed by Soviet engineer and sci-fi writer Sergei Zhitomirsky in 1971.
Missions to Venus constitute part of the exploration of Venus. The Soviet Union, followed by the United States, have soft landed probes on the surface. 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 ...
Venera 13 and 14 were identical spacecraft built to take advantage of the 1981 Venus launch opportunity. The probes were launched five days apart, with Venera 13 launching on 30 October 1981 at 06:04 UTC and Venera 14 launching on 4 November 1981 at 05:31 UTC.
Venera 8's photometer measurements showed for the first time that the Venusian clouds end at a high altitude, and the atmosphere was relatively clear from there down to the surface. The on-board gamma ray spectrometer measured the uranium / thorium / potassium ratio of the surface rock, indicating it was similar to Alkali basalt .
A comparison of past surface-imaging missions to Venus, of which Magellan is the most recent. VERITAS will collect data to help answer these questions in several ways. High-resolution imagery will be obtained using an X-band radar configured as a single pass interferometric synthetic aperture radar (InSAR). [19]
Whereas all ground missions measured their operational time in minutes or hours, several Soviet missions found success in launching small balloons, that operated until their batteries were exhausted (days). At 55 km of altitude, the atmosphere of Venus is 27C and .5 bar (the equivalent pressure to about 18000 feet on Earth).

'Venus-9'), manufacturer's designation: 4V-1 No. 660, [4] was a Soviet uncrewed space mission to Venus. It consisted of an orbiter and a lander. It consisted of an orbiter and a lander. It was launched on June 8, 1975, at 02:38:00 UTC and had a mass of 4,936 kilograms (10,882 lb). [ 5 ]
