Scientists are considering the possibility of sending humans to Mars in the coming decades.
A wonderful dream that human being explore to Mars is facing tremendous challenges. The reading passage proposes several major problems that would happen in extremely long-distance space traveling. The lecturer, moreover, suggests three possible solutions to these concerns, respectively.
First of all, the professor argues with the food supplement problem that essential foods, water and oxygen will be running out in a minimum two-year space trip by a new-invented product, Hydropunix. This special food could be well-packed into a relatively small size as well as large number in spaceship and, therefore, provide sufficient food and water supplement. In addition, the recyclable resting such as water is able to re-use and the carbon dioxide could be transferred into oxygen.
Secondly, the professor suggests that human could concur zero-gravity environment through regular exercise. An astronomer, serving in International Space Station, has proved this statement by himself. Hence, it is possible for humankind to survive in the extremely low gravity circumstance.
Finally, the professor contends the statement that the radiation in cosmos is quite harmful for spaceman. In fact, the harmful radiation is only occasionally happened, and the astronomers could be protected in the special device.
