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 and the listening lecture, both talk about the possibility of living on Venus. The passage accounts for Venus because of its certain features, does not have mandatory conditions for human living, but on the other hand, the lecturer explains in the listening that it is possible that a permanent human presence maintains.
First, the author explains that Venus has a pressure 90 times greater than Earth. Accordingly, if a spacecraft want to land on the venus, it will crush to the surface of this planet by this high pressure. Contrariwise, The lecturer believes that this problem can be solved by constructing with these floating stations. The lecturer describes that if a station is built 50 kilometers up the level of this planet, the humans do face no danger at all.
Second, the author says there is a problem of lack of water and oxygen in the atmosphere of Venus, and all the atmosphere of Venus is comprised of carbon dioxide, nitrogen, and sulfuric acid, etc. However, the lecturer pays to this fact in a different way. The lecturer reveals that the rocks and chemical materials on Venus contain the water and oxygen which needed for human living and humans can excavate these compounds to supply the required water and oxygen.
Finally, the author indicates that in addition to the mentioned problems, there is a scarcity of sunlight in Venus. He says that about 60 percent of the sunlight that hits Venus is reflected back into space by the thick clouds that fill the atmosphere. So it faces humans with a lack of sufficient energy to use for their equipment. On the other hand, the lecturer explains that humans can solve this issue by installing the two-sided solar panels on the appropriate altitudes to absorb both transmitting and reflecting sunlight that provides enough energy to use.
