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 professor in the lecture does not agree with the three pieces of evidence provided by the reading about the impossibility of humane presence on Venus.
The professor tries to persuade his class that all these pieces of evidence are not convincing and the human can present on Venus if they stay in a balloon 50 Km above Venous' atmosphere.
First, the professor asserts that because the high of this balloon which is 50 Km, the pressure inside it will be equal to the pressure on Earth's surface. This point directly contradicts the point from the reading which state that the pressure on Venus is at least 90 times greater than the pressure on Earth'surface so, almost anything humans might land on Venus would be crushed.
Second, regarding oxygen and water supply, The lecture avers that Venus's atmosphere made up mostly of carbon dioxide and sulfuric acid. Therefore, we can use them in chemical reactions to produce water and oxygen. Again, this point refutes the pint from the reading which claims that there are no reservoirs of water on Venus, surface and its atmosphere contains hardly any oxygen.
Third, regarding sunlight and electricity, the speaker argues that the clouds at 50 Km high are not thick like clouds over Venus,s atmosphere. As a result, sunlight can get through these clouds easily. Furthermore, The clouds above Venus's atmosphere will reflect sunlight. So, we can collect sunlight from both reflection and clouds to produce electricity as we will have enough energy for that. This point casts doubt on the point from the passage which says that very little sunlight reaches the planet's surface so there is lake of light and energy.
