TPO-50
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. One problem is that a round-trip to Mars and back is likely to take at least two years. The trip to the Moon lasted only a few days, and it was easy to bring enough supplies of food, water, and oxygen; but the cargo capacity of space vehicles is too limited to put on board the food, water, and oxygen required by a crew for a period of two years. Without those essentials, though, a Mars mission is impossible. A second problem is that astronauts on the Mars mission would be in the zero-gravity environment of space for many months at a time. Spending a long time in the zero-gravity environment has negative effects on the human body, such as decreased muscle mass and lower bone density. Over the course of a two-year mission, the effects would be so severe, they would make it impossible for humans to make the trip without experiencing grave medical problems. Finally, astronauts on a mission to Mars would be exposed to dangerous levels of space radiation, much of which comes in the form of charged particles emitted by the Sun. Earth’s magnetic field, which normally protects us from dangerous solar radiation, would not be able to protect a spaceship traveling in interplanetary space. Constructing a shield that would protect the whole spaceship from space radiation is at present impossible because it would add too much weight to the ship.
Both the reading and the listening materials discuss three hypotheses around mars traveling. The reading points out that traveling to the mars is impossible, however, the listening uses a number of points to refute the reading passage.
The article of the reading, firstly, suggests that astronauts cannot manage their food, water, and clean air supply during their trip to Mars because this travel takes at least two years. however, the professor elucidates that "hydroponic"-technology that makes possible to plant into the small area in outer space- solve the problem of a capacity of cargo limit.
Furthermore, the reading passage mentions another challenging problem about astronauts' health issue. Living in outer space, zero gravity, negatively affect muscle mass during two-years long trip. Nevertheless, the listening gives a solution that many astronauts went to space for a few weeks to months. They managed to slow muscle mass density by doing regular exercise in space.
The last point of the reading adds that hap hazardous solar radiation of the sun can be a more serious problem with a spaceship. The listening rejects this idea saying that solar radiation rarely is dangerous hence if astronauts protect them from that moment, it is manageable to set a spaceship with small shield room.
