Venus, often called Earth’s twin because of its similar size, mass, and rocky structure, has an environment that is extremely different from our planet. The surface pressure on Venus is about 92 times greater than Earth’s, which is equivalent to being nearly 900 meters underwater on Earth. Such pressure would crush most human-made equipment. Additionally, Venus is the hottest planet in the Solar System, with an average surface temperature of around 462°C—hotter than Mercury, even though it is farther from the Sun. The atmosphere of Venus is mostly carbon dioxide, with thick clouds of sulfuric acid that block sunlight and make it impossible to see the surface from space. As a result, scientists use radar imaging to study the planet's surface. These images have revealed features such as mountains, volcanic plains, and even a towering peak called Mount Maxwell, which is over 10,000 meters high. At this altitude, the pressure and temperature are much lower than on the surface, offering a slight break from the otherwise extreme conditions. In 1982, the Soviet probe Venera 13 set a record for the longest survival on Venus, operating for 127 minutes before being destroyed by the intense heat and pressure. This mission provided some of the first images of Venus’s surface and valuable data about its harsh environment. The conditions on Venus, including the presence of supercritical carbon dioxide—where the gas and liquid states of a substance are indistinguishable—highlight the extreme challenges faced by any technology attempting to operate there. Studying Venus is crucial for understanding how rocky planets evolve over time. Despite its similarities to Earth, Venus has developed an environment that is completely inhospitable, raising questions about why Earth has remained habitable while Venus has undergone a dramatic climate shift known as a thermal runaway. This divergence helps scientists explore the mechanisms behind extreme greenhouse effects and the factors that determine a planet’s ability to support life. It also provides a useful comparison for studying rocky exoplanets beyond our Solar System, some of which may experience similar extreme conditions.
