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.
Both the reading and tbe lecture are talking about maintaining human presence on Venus, but the speaker with the perspective made in the reading material that it is possible for human to maintain a permanent presence, which disagrees with the standpoint in the reading that it is impossiable.
The reading first claims that atmoshperic pressure at Venus's surface is greater that that at Earth's surface. However, the professor objects it with a new proof. The professor says that human can live in a balloon floating above 50 kilometers above the Venus's surface where the pressure is suitable for humans.
Furthermore, the reading conceives that there are no water and oxygen on Venus's surface, which is impratical to ensure a supply from Earth. In contrary, the professor asserts that chemical processes can be used to produce water and oxygen, and the chemical material can can be absorbed from the atmosphere. There is no need to transfer water and oxygen from Earth.
Finally, the reading material proposes that because of the thick clouds, there is very little sunlight that can reach the plant's surface. And humans can not power the machines because of the absence of light. While the professor points that there is no thick clouds above 50 kilometers above the surface so it is easy to receive light from the Sun. In addition, reflacted sunlight can also be used to power the machines and equipment.
Therefore, the speaker departs totally from the opinion on the topics made in the reading.
