In this set of materials, the reading passage discusses that journey to Mars need to overcome some serious problems which nowadays we cannot fix them, and was shared three of these problems. While in the listening the professor casts doubt on what was presented in the text and believes that travel to Mars would be definitely challenging, but scientists have been proposed several solutions for these problems.
First of all, in the text, it is clearly mentioned that travel to Mars is a very long trip and providing enough food and other supplies would be a big challenge. However, the professor claims that we can use the hydroponic technique for growing crops on water which need very fewer space rather than soil. In addition, we can recycle this water and use it as drinking water. Moreover, the growing plants would absorb CO2 and produced fresh air in the spacecraft.
In addition, the professor disagrees with this idea that the presence of people in the zero-gravity environment on Mars produced health problems that cannot avoid. She says that today astronauts spend a long time on space on zero-gravity and this condition did not create serious health damage to them. Astronauts can through regular exercise decrease the rate of losing muscle mass, and by consuming calcium, they can reduce the speed of losing bone density.
Finally, in the text, it is stated that the astronauts would be exposed to the very dangerous solar radiation. The professor subscribes that sun occasionally produce those particular dangerous radiations and we can use some instruments to monitor radiation and astronauts do their activities in the shielded portion until the dangerous radiation pass from other parts.
