Many scientists believe it would be possible to maintain a permanent human presence on Mars or the Moon. On the other hand, conditions on Venus are so extreme and inhospitable that maintaining a human presence there would be impossible.
First, atmospheric pressure at Venus’ surface is at least 90 times greater than the pressure at Earth’s surface. This means that a force of 100 kilograms is pressing down on every square centimeter of surface. All spacecraft that have landed on Venus have been crushed by this extreme pressure within an hour of landing. Almost anything humans might land on Venus would be crushed as well.
Second, as far as we know, there are no reservoirs of water on Venus' surface, and the planet's atmosphere, made up mostly of carbon dioxide, nitrogen, and sulfuric acid, contains hardly any oxygen or water vapor Water and oxygen would therefore probably have to be supplied to Venus from Earth. The idea of ensuring a regular supply of water and oxygen from Earth is impractical in the extreme and would probably defeat the purpose of establishing a permanent station on Venus.
Third, very little sunlight reaches the planet's surface. About 60 percent of the sunlight that hits Venus is reflected back into space by the thick clouds that fill the atmosphere, which means that only 40 percent of the sunlight can get through the clouds Below these clouds is a dense layer of carbon dioxide, which blocks even more light, so very little light reaches the surface. The lack of light would prevent the use of solar power cells, so humans could not get electricity to power their machines and equipment.
the articles state that venus conditions are very difficult to inhabitant by humans , and provide three reasons for support .however, the professor explains that it could be possible to human presence there and refutes each of the author's reasons.
first, the reading claims that atmospheric pressure on the surface of Venus is much higher than earth's atmosphere and anything will crash on its surface. the professor refutes this point by saying that if they make a floating station above the venus surface which is at least 50 km up the atmospheric pressure will equal that of earth, he states that no crush will occur.
second, the reading posits that there is no reservoir of water and o2 and bring them from earth is impossible.the professor says that there are other chemicals like co2 and sulfuric acid could be used to generate water and o2 .
third , the article says that there is no enough light reach into surface and most of it reflected by clouds, the professor oppses this point by explaining that station will be 50km above so light will reach more and reflected light also may collected and benefit from them in power and electricity .
