The reading states that it is not possible to keep humans on Venus and provides three reasons to support this claim. However, the professor opposes these arguments and refutes each of the points made in the reading.
First, the passage mentions that since the atmosphere pressure in Venus is ninety times greater than the one on the Earth, anything that lands on Venus will be crushed. The professor disagrees with this idea and explains that if they try to establish a flouting station like a balloon fifty kilometers above the surface, the pressure problem will be solved. He adds that the pressure at high altitudes is lower than the one near the surface of the planets and by making this floating station the pressure of Venus will be equal to the Earth's pressure.
Second, the reading asserts that there is no water or oxygen in Venus and if humans want to stay on Venus, they will have to receive the supply of vital materials from the Earth which seems unrealistic. This contradicts the lecture that states, Venus has a great amount of carbon dioxide and sulfuric acid which can be used for producing water and oxygen supplies for people who want to stay in there. Therefore, there is no need for sending these compounds from the earth.
Third, the reading claims that there are thick clouds in Venus that blocks the great percentage of sunlight from reaching Venus' surface and make it impossible to use solar cells in Venus. The professor refutes this idea and argues that the clouds are not thick and it is possible to filter the sunlight and use it for electric energy. He explains that the amount of energy that is reflected by clouds also can be used at the height of fifty kilometers of Venus' surface and they also can use direct sunlight. In this case, there will be more than enough energy to support a station on Venus.
