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 passage explores the issure of sending humans to Mars, proposing three difficulties that are impossible to settle. The speaker deals with the same issue, however, contrary to the author's standpoint, she thinks these obstacles can be overcome. She raises three specific points to support her idea.
First, the passage suggests that there will be no room to take enough resources like food, water and oxygen, because the trip takes over two years and the capacity is limited. Whereas, the speaker proposes a solution. she thinks that astronauts can grow plants in the water instead of soil, which will take less room and the plants can serve as food to consume, help recycle water and produce oxygen as well as absorbing carbon dioxide. Thus, the problem can be solved by this proposition.
Moreover, while the passage contends that staying in zero gravity for a long time will have a negative impact on human's body, the speaker maintains that the problem has been investigated and solved by practice. she points out that there have been some astronauts spending many months in zero-gravity. They do regular exercise to prevent muscle mass from decreasing, and eat vitamin and minerals to keep bone density. In other words, the health problems have been effectively settled.
Finally, despite the fact that the passage claims that being exposed to high level of space radiation in interplanetary space is detrimental to astronauts' health and it is impractical to build a shield to protect the spaceship due to its weight, the speaker hold fast to the opposite standpoint. she point out that the harmful radiation just happens occasionally. Therefore, the spaceship can be equipped with a special instrument to detect radiation, and only a part of the spaceship needs to be shielded. When harmful radiaiton arrives, the astronauts can go to the shielded area.
