text: Venus has a thick atomosphere of almost 97 percent carbon dioxide blankets. The really big thing is the temperature of Venus atomosphere. On Venus surface, temperatures average over 800 degrees Fahrenheit, and the pressure is 90 times greater than what the Earth is. Such an evironment as Venus could crush a submarine accustomed to diving in the deepest oceans. Venus has the hottest surface temperature of any planet in our solar system. Venusian geolgoy and weather present additional impediments like erupting volcanoes, powerful earthquakes, and frequent lightning strikes to probes seeking to land on its surface. Each previous mission was unmanned, and for a good reason, sincce no spacecraft survived the landing for more than a few hours. Not a single spacecraft has safly touched down in Venus for over three decades. This is why it is really dangerouse to study Venus atompshere and surface of Venus
