There is no water on the surface of Venus because the temperature is too hot. Venus Express has made the first detection of an atmospheric loss process on Venus's day-side.
Where Venus' Water Went. Additionally, the proximity of Venus to the sun has very little to do with why it's so hot. Astronomers have detected that the atmosphere of Venus consists of 0.002% water vapor. By Jeanna Bryner 05 January 2009. Compare that to the Earth’s atmosphere, which contains 0.40% water vapor. Any free hydrogen in the upper atmosphere boils off from the relatively high solar radiation and is gone. Less than .002% in the atmosphere. Is There Water on Venus?
Earth has .4% in its atmosphere. Venus, like Earth and Mars, is immersed in a flow of charged gas from the sun. The surface of venus is much too hot to maintain any liquid water, though. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. There is a very small amount of water vapor in the atmosphere of Venus. Together, these discoveries bring planetary scientists closer to understanding what happened to the water on Venus, which is suspected to have once been as abundant as on Earth. Shares. So no water.
