Both the reading and listening are arguing over a question whether it is possible to send human being to Mars. The reading lists out three problems to a successful carrying out. However, the listening offers three solutions to these questions.
First, the reading raises the question that it takes too long to send people to Mars, approximately two years and no spacecraft could take that many loads of food, water and life essentials. Instead, the listening says this is not a real problem since the astronauts could use hydroponics to grow crop plants in water and food will not be an obstacle. Also, they could grow plants with recycle waste water and reuse it as clean water vapor, which could be drunk. Plus, since all plants do photosynthesis, the astronauts could breathe fresh air released by them.
Second, the reading asserts that living in a zero-gravity environment would exert a negative effect on one’s health. Nevertheless, the professor says that the astronauts have learned to use several techniques to make up for the health issue. They will do regular exercise to prevent muscle mass from decreasing and take vitamins and minerals to slow down problem with their bone density. In another word, they’ve figured out how to cope with the potential health problem.
Third, the reading claims that radiation emitted by the sun would be dangerous to astronauts. This time professor subtly rejects by pointing out that a third solution has come out. The spaceship would be equipped with a special instrument to monitor the radiation. What’s more, the device could also shield against the radiation. When astronauts meet the period of a large amount of radiation, they could hide behind the shielded areas and come out when the danger has passed.
The reading states that the scientists are going to find the possibility of sending human to Mars, but there are some problems about this project. However, the speaker finds all ideas dubious and presents some evidences to refute them all.
First, the author argues that a round trip to Mars and back is probably to last 2 years, while a journey to the moon takes just a few days. So, bringing enough sources of food, water and oxygen is easy in the trip to moon. Because of the limited capacity of space vehicles, it seems that putting a great amount of food, water and oxygen for 2 years in Mars mission is impossible. Conversely, the lecturer brings up the idea that the astronauts to solve this problem can use the hydroponic which is a technique that use water rather than soil to grow plants and with this method they can cultivate the required plants with the recycling waste water, as a source of food and drinking water. Also, the plants by photosynthesis can absorb dioxide carbon and release oxygen to provide fresh air.
Furthermore, the reading passage holds the view that during the Mars mission, there is a zero-gravity environment that astronaut may face to it and in the long run, it can be dangerous for astronauts' body. On the contrary, the professor underlies the fact that astronauts can prevent the muscles' mass decreasing with regular exercises or taking the minerals like Calcium can avoid the bone density depletion.
Finally, the reading asserts that during the mars mission, the astronauts can be subjected to the dangerous levels of space radiation especially by the sun and constructing a shield to prevent the spaceship from space radiation may add the excessive weights to the spaceship. In contrast, the speaker dismisses the issue due to the fact that the solar radiation will not be dangerous all the time and occasionally during the particular time they may be dangerous. So after the detection of the dangerous levels of solar radiation by a special equipment, the astronauts can use a small shelter to hide themselves until the danger has passed.
