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 reading passage says that permanent Station on Venus, opossite of the percense of human on Mars or the Moon, is impossible because some reason. However, the lecture casts doubt on this view.
The speaker says that the pressure at Venus' surface which is at least 90 times greater than the pressure at Earth' s surface, is not a reasonable explanation for impossibility of station on Venus. Because there are a pressure similar the Earth at the around 50 kilometer of Venus and if the station establish there, that station will not have any problem with pressure at that position.
The lecturer also refutes the reading' s claim about absence of any water and oxygen on the Venus' s surface which make it impossible to station of human on that place. She explain' s that because there are some compound like carbon dioxide and sulfuric acid on Venus, if the station be on the atmosphere of it, the oxygen can be produced by some chemical process. So there are not any needs for bring oxygen from Earth.
Finally, she explains that the clouds which are around the Venus are not so thick to make a crucial problem for sunlight to get through it. And she claims that if the station be at atmosphere, the reflection of the sunlight by clouds can be absorbed by the station. And this lights can make electricity which it needs at that position without any problem.
At the end, the speaker says that it is possible for humans to think about permanent station on venus.
