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.
Recently, there has been a ton of debates about the possibility of building a permanent station on Venus. More specifically, according to the passage, the writer puts forth the idea that it is unlikely that humans can live on Venus. In the listening passage, the lecturer is quick to point out there are some serious flaws in the writer's claims. The professor believes that humans can build floating stations in Venus' atmosphere, and addresses, in detail the trouble with each point made in the reading text.
First and foremost, the author of the reading states that atmospheric pressure at the surface of Venus is extremely higher than the pressure at Earth's surface. Some professionals in the same field, however, stand in firm opposition to this claim. In the listening, such as the professor states that the floating stations in Venus have pressure equal to the pressure on Earth's surface. He goes on to say that the atmospheric pressure in Venus decrease with height.
One group of scholars, represented by the writer, thinks that Venus' surface does not contain any water or oxygen and it is only made from huge amounts of other gases. Of course, though, not all experts in this field believe this is correct. Again, the professor specifically addresses this point when he states that humans can produce water and oxygen in the floating stations by using available gases on Venus' surface.
Finally, the author wraps his argument by positing that a little amount of sunlight reaches the Venus' surface due to the thickness of Venus' clouds. Not surprisingly, the lecturer takes this issue with his claim by contending that the clouds in Venus are not very thick at 50-kilometer height. Moreover, power cells on the stations can collect the sunlight easily.
