The reading passage and the lecture have a discussion about the possibility of humans' mission to Mars. The article mentions three potential problems. On the contrary, the lecturer considers none of them would affect the mission with certainty.
First, the article suggests that supplies for astronauts will be a problem. However, the opinion has been opposed by the professor with new proof. The professor says that a technique called hydroponics can solve the issue. With the new technology which takes little place of space ships, wastewater can be recycled into usable recourse also make the air fresher. As a result, the opinion from the reading has been challenged heavily.
Moreover, the author claims that a zero-gravity environment will cause health concerns, while the lecturer states that during years of research, scientists figured that regular exercise helps the astronauts maintain body strong, which differs from the reading as well.
Finally, the author believes that radiation from space is a crucial issue. On the other hand, the professor on the listening material maintains that the radiation is not at a dangerous level, and the shelter can prevent astronauts expose directly to the radiation. Thus, the reading passage has been refuted again.
Therefore, the speaker departs totally from the opinions on the topic made in the reading.
