Nov 5, 2018 · Planetary scientists had learned a great deal about Venus from both Earth-based observations and spacecraft encounters. Two American spacecraft, Mariner 2 in 1962 and Mariner 5 in 1967, studied Venus during their fly-bys and revealed much about the planet’s atmosphere, showing it to be much hotter (527o C) and denser (75-100 atmospheres) than previously expected, and found only a very weak ...

There have been 46 space missions to the planet Venus (including gravity-assist flybys). 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.

The 10 Mariners visited Venus, Mars and Mercury for the first time, and later returned to Venus and Mars for a closer look. The final mission in the series, Mariner 10, flew past Venus before going on to Mercury for a total of three flybys. Mariner 9 became the first spacecraft to orbit another planet when it reached Mars in 1971.
