text: First, there's a thick atmosphere of almost 97 percent carbon dioxide blankets Venus. On the planets surface temperatures average over 800 degress Fahrenheit, and the atomospheric pressure is 90 times greater that what we expreinced on our own planet. These conditions are far more extreme than anything humans encounter on Earth; such an enviroment would crush even a submarine accustomed to diving to the deepest parts of our oceans and would liqefy many metals. Also notable, Venus has the hottest surface temperature of any planet in our solar system, even though Mercury is closer to our sun. Beyond high pressure and heat, Venusian geology and weather presnt additional impediments like erupting volcanoes, powerful earthquakes, and frequent lightning strikes to probes seeking to land on its surface.
