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 states that Venus is not suitable for human living and provides three reasons of support.
However, the lecturer is challenged the claims made by the author. He explains that it would certainly possible to live in Venus and refutes each of the author's claims.
First of all, the reading states that venus surface at least 90 times higher pressure than the pressure at Earth surface and as a result, almost anything human landed on venus have been crused as well, that's why people could not survive Venus. This specific argument is challenged by the lecturer. He says that the hight of the surface and the pressure is exponential related, though the surface of Venus has greater pressure but above 50 meters from the surface has sustain normalpressure. Furthermore, The lecturer says that abover 50 meter build a flaoding station like balon would possible to landing and people could survive.
Secondly, the author argues that Venus has no water and atmosphere consist of carbon dioxide,
nitrogen and sulfuric acid rather than oxygen or water vapor. thus, without water could not survive and to supply water from Earth to Venus is completely impractical thinking. The lecturer, however, rebuts this claim that by the use of chemical compound with carbon dioxide and sulfuric acid in Venus's atmosphere would be possible to turn water, thus no needed to supply water from Earth.
Finally, the article posits that humans in Venus could not operate their equipment because Venus atmosphere filled by thick cloud and below this cloud consists of dense carbon dioxide as a result, sunlight blocked and can not reach in Venus surface. In contrast, the lecturer's position is that
above 50 meters the surface of the atmosphere is thin and sunlight can get through is surface easily. thus this way people would use of solar power and survive.
