Landing a spacecraft on Venus presents significant challenges due to its hostile environment. The planet's dense atmosphere, composed mainly of carbon dioxide with clouds of sulfuric acid, creates extremely high surface pressure, about 92 times that of Earth's. This, combined with surface temperatures of around 467 degrees Celsius (872 degrees Fahrenheit), can crush and melt spacecraft materials. Additionally, the thick cloud cover makes it difficult to use solar power and hinders communication with Earth. These factors have made Venus a challenging destination for spacecraft, requiring highly specialized and robust technology for successful missions.
