A wonderful technical achievement.

Quote:Astronomers have detected that the atmosphere of Venus consists of 0.002% water vapor. Compare that to the Earth’s atmosphere, which contains 0.40% water vapor.http://www.universetoday.com/36291/is-th...-on-venus/

Quote:Venus could be an inhabitable planet in progress, maybe it was or maybe neither.It would have started with slightly MORE Hadean conditions (more bombardment, more solar radiation) than the Earth, which is similar in size. I suspect that its surface temperature never fell to the point where water condensed out of the atmosphere to form seas BEFORE the solar wind had blown away the water vapor. Is that speculation?
Quote:If it was than we could longshot speculate there is some sort of remnants of life or even (longer shot) civilization.Nope.
Quote:Venus is sometimes referred to as Earth's sister planet because of its similarity to the Earth in size and mass, but its climate is very different. Venus has a massive CO2 atmosphere which is extremely hot due to the greenhouse effect and is covered by sulfuric acid clouds.
