Scientists are considering the possibility of sending humans to Mars in the coming decades. Although there have been successful manned missions to the Moon in the 1960s and 1970s, Mars is 150 times further away from Earth than the Moon is. Thus the project of sending humans to Mars would require solving an array of problems the Moon missions did not have to face.
The reading and lecture are both about mission of astronauts to travel Mars. The author of the reading believes that there are three solutions required to successfully land on Mars. However, the lecturer casts doubts about the claims made in the passage and refutes all the theories presented.
First of all, the author points out that travelling to Mars would take two years. The article notes that their space ship has no enough cargo space to cater to the astronauts daily supply of food, water and oxygen for two years. Conversely, the point is challenged by the lecturer. She says that hydrophonics is one solution to solve the pressing problem. Furthermore, she argues that astronauts can grow plants on little space they have and can cultivate food crops in the spaceship. In addition, they can recycle waste water into clean water vapor and will be used as portable drinking water and also can have fresh air.
Secondly, the author contends that astronauts will be facing zero gravity on Mars. The article establishes that it has negative effects on human body such as decrease in body mass and bone density. On the contrary, the lecturer rebuts this argument. She suggests that other mission includes dealing with zero gravity for several months and it can be addressed by doing regular exercise so that the muscles will be healthy, talking calcium supplements to strengthen bones. As a result, the lecturer implied that it is possible to travel to Mars.
Finally, the author states that astronauts are exposed to dangerous space radiation. The article denotes that creating shield for the whole space craft will be impossible because it will create excessive weight in the ship. The lecturer, on the other hand, posits that solar radiation exposure are not dangerous when the contact is minimal. She puts forth the idea that small shielded shelter can be placed to protect the astronaut with the solar radiation and it is light weight and do not pose extra weight on the spacecraft. Also, there are instrument to detect radiation and they can stay on the shielded area until the radiation is over.
