Part B:

What are some of the challenges astronauts face living in a microgravity environment? How are these challenges overcome?

When living on the ISS astronauts experience many temporary and long-term health effects from living on the ISS. The reason astronauts experience many health effects is because when you are in space your experience weightlessness, or zero gravity.

Some of the temporary effects of living on the ISS are the astronauts experience disruption to their proprioceptive system, which is a system in the body which tells the arms, legs and other parts of the body are in relation to each other. This effect can cause astronauts to feel nauseous for a short period of time.

A long-term affect for the astronauts is that over time their calcium in their bones start to weaken making it easier for the bones to be broken. Once the astronauts return back to earth it takes months of rehabilitation to adjust to earth
