Venus is scarred by numerous impact craters distrubuted randomly over its surface.Small craters less that 2 kilometers (1.2 miles) are almost non-existent due to the heavy Venusian atmosphere.Among the personal ads there are many profiles with hidden pictures, because many persons asked for privacy; however you will be able to see those pictures too, after you will become a subscriber and you will receive a password. ru, Last year in July me and my lady had our first meeting in Cheboksary.After a wonderful meeting in Russia and holidays in Egypt, we decided to marry in September 2006.Both formed about the same time and condensed out of the same nebula.However, during the last few years scientists have found that the kinship ends here. It has no oceans and is surrounded by a heavy atmosphere composed mainly of carbon dioxide with virtually no water vapor. At the surface, the atmospheric pressure is 92 times that of the Earth's at sea-level.One theory suggests that the bright material might be composed of metallic compounds.
Hugh lava flows, extending for hundreds of kilometers, have flooded the lowlands creating vast plains.
Four of the most successful missions in revealing the Venusian surface are NASA's Pioneer Venus mission (1978), the Soviet Union's Venera 15 and 16 missions (1983-1984), and NASA's Magellan radar mapping mission (1990-1994).
As these spacecraft began mapping the planet a new picture of Venus emerged.
Magellan images of highland regions above 2.5 kilometers (1.5 miles) are unusually bright, characteristic of moist soil.
However, liquid water does not exist on the surface and cannot account for the bright highlands.
Early astronomers once thought Venus to be two separate bodies.
