▶ Your Answer :
The reading passage points out several
problems with a manned mission to Mars. On the other hand, the lecturer provides
possible solutions to each problem.
First, according to the passage, Martian
dust can cause serious troubles to both spaceship and astronauts such as malfunction
and health problems. However, the speaker argues that dust can be controlled by
utilizing sound technology. To be specific, when high-pitched sound is created,
it can remove dust away from the spaceship and a human.
Second, the writer claims there is a high
risk that astronauts might suffer from anxiety and depression since they carry
out their mission for an extend period of time alone. On the other hand, the lecturer
maintains that this problem is manageable through several methods. For example,
an astronaut undergoes a special training which teaches how to deal with
isolation. Furthermore, they can receive counselling including video therapy
during their missions.
The last point made by the author is that a
manned Mars expedition poses a huge financial burden on a country because it
costs a lot. Also, there is no guarantee that they would obtain immediate benefit
from the missions. However, the lecturer suggests that it can be solved if several
nations pool the resources together. For example, international space station
built by using resources of fifteen countries shows international partnership
is possible. Moreover, even if it might appear an expedition does not produce
immediate effect, it leads to technological advances in the long term.
