In 1975 the Soviet Union sent two spacecraft landers to Venus, Venera 9 and Venera 10. These landers were the very first to reach the planet’s surface and they sent back images to the Earth. It is not a very clear picture but it is famous since this is the first photograph we have of the surface of Venus. The Venera 1 space probe was launched in 1961, but lost contact with base. The USA also lost their first probe to Venus, Mariner 1, although Mariner 2 was able to take measurements of the planet in 1962. The Soviet Union’s Venera 3 was the first man-made craft to land on Venus in 1966.

The atmosphere on Venus is composed of carbon dioxide. The surface is heated by radiation from the sun, but the heat cannot escape through the clouds and layer of carbon dioxide. (This is a “greenhouse effect”).

Venus, the second planet from the sun, is named for the Roman goddess of love and beauty. The planet is know as the twin sister of planet Earth. Venus is the hottest planet in our solar system. The average surface temperature is 462 °C, and because Venus does not tilt on its axis, there is no seasonal variation. The dense atmosphere of around 96.5 percent carbon dioxide traps heat and causes a greenhouse effect. Venus rotates couter-clockwise with Uranus. Other planets rotates clockwise. Venus is known as the Morning Star and Evening Star because the planet was sometimes viewed from Earth in the daytime.
