About Venus

So, in my previous posts, I mentioned Mars a lot. The reason behind this is that it is the best option for becoming our second home, and also we have the technology to travel through Mars and examine the needed properties. While doing research for my blog, I came across an article about how Venus went through global warming. And it sure does sound familiar. So today, I will briefly mention Venus and why it should be a warning sign for us. 

Venus has the same mass and same mass as Earth. It has a thick atmosphere. Its atmosphere contains greenhouse gas carbon dioxide and its clouds are made up of sulfuric acid. It rotates so slow that 1 year on Earth is equal to 2 days in Venus. It is the hottest planet we know, but it is not the closest planet to the Sun, its surface temperature is 460 degrees in Celcius. The best survival rate for a robot in Venus is 2 hours. 

Heres a brief video about Venus;

Data collected at NASA's Pioneer Mission to Venus has given some insight into Venus's past climate and geology. It is suggested that Venus had a very familiar climate and geology to ours, but its seas has evaporated because of its nearness to Sun. "As a result, the planet’s early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. With no water left on the surface, carbon dioxide built up in the atmosphere, leading to a so-called runaway greenhouse effect that created present conditions."
