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 tenor is mainly about an analysis of the possibilities for human to live under condition on Venus. The article shows three traits that demonstrates the inhospitable for human being. However, the professor in the lecture disagrees. He proposes that a floating station would be a solution to deal with the problems.
First of all, the atmospheric pressure for human survival. The paragraph suggests that the pressure at the surface of Venus is so high that people would be crashed and dead. However, the professor claims that the atmospheric condition at the height as sixty kilometer above the surface of Venus is equal to it of Earth and suitable for human to build a floating space station.
Secondly, the argument mentions that Venus lacks water and oxide-gen for human to sustain their life. In contrast, the teacher proposes that they could be extracted from carbon dioxide through chemical process.
Finally, the paragraph claims that the sunlight energy at the surface of Venus is barely to power machines and equipment because most sunlight is reflected by the thick cloud and only 40 percent of it is allowed to reach the surface. Moreover, the blocked layer consisting of carbon dioxide reduces energy of sunlight further. On the contrary, the professor proposes that the circumstance at the high floor, 60 kilometer above the surface of Venus, is able to collect the sunlight energy from both reflected back toward the sun and down to the surface. It effectively powers the electric machine and devices.
