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 debate on the possiblity of human residence on the Venus as it is theoretically possible on the Moon and Mars. More specifically, in regard to the passage, the writer puts forth three different ideas. In the listening passage on the other hand, the lecturer is quick to point out that there are some serious flaws in the writer's claims and addresses, in detail, the trouble with each point made in the reading passage.

First and foremost, the author of the article states that because of high atmospheric pressure at Venus' surface, anything that lands on Venus, including humans will crush. Some professionals in the same field, however, stand in firm opposition to this claim. In the listening, for instance, the professor states that a floating ballon shaped space station could stands 50 km above the surface of the Venus. He goes on to say that as the pressure will decrease as the elevation rises, atmospheric pressure will be just like the Earth's surface pressure at the height of 50 km, so it would be tollerable.

Furthermore, on group of scholars, represented by the writer, thinks that because of the lack of water and oxygen existance on the Venus and the need for supplying them from the Earth, it would be impossible to defeat the purpose of establishing a permanent station on Venus. Of course, though, not all experts in the field believe this is accurate. Again, the speaker addresses this point when he points out that with the use of chemical processes in the floating station mentioned above, scientists can overcome their need of oxygen and water.

Finally, the author brings his argument to a close by suggesting that The lack of light would prevent the use of solar power cells, so humans could not get electricity to power their machines and equipment. Not surprisingly, the lecturer takes issue with this claim by contending that the amount of sunrise in 50 km above the surface of the Venus is high. So, by the use of solar panels, scientists can produce the electricity they need to power their equipments.
