Scientific paper
Radar, ultraviolet, and space-probe observations of Venus are discussed. Difficulties in observing the surface are described together with determination of the 243-day rotational period and possible generation mechanisms of the very high winds. The chemical composition of the atmosphere and clouds is discussed in detail, emphasizing the atmospheric oxygen deficiency and the presence of hydrogen chloride, hydrogen fluoride, and sulfuric acid. Measurements of the surface and cloud-top temperatures are reviewed, physical properties of the atmosphere are considered, and the greenhouse effect is explained. It is shown that the surface of Venus is apparently much smoother than that of the moon, Mercury, or Mars and is characterized by a rather flat terrain. It is noted that while Venus is assumed to be fundamentally similar to earth in regard to its internal structure, the lack of water and absence of a magnetic field make it strikingly different. The evolutionary history of the planet is considered in the framework of the greenhouse effect and the problems raised by the present-day lack of water.
