He note out that, Those men will face the problem like, reduction in muscle mass and lower down the bone density. In contrast to that, The speaker contends that, now a days many astronauts are staying in zero gravity zone for more than two months. He point out that, they developed several technique to mitigate this problem; like a regular exercise and taking the table of calcium and different mineral.

Lastly, The author believe that, radiation of charged particle is harming the astronauts. He also argues that, now a days it is iimpossible to develop the shiel which can protect them. on the opposite side the tutor stand out that, rsolar radiation are coming out in specific time and scientis are
