Question

There has been discussion about people moving from Earth to Mars in the future. An organization called MarsOne is recruiting investors and volunteers for the first manned mission there. The gravity on Mars is 62% lower than the gravity on Earth, meaning that someone weighing 100 kg on Earth would weigh 38 kg on Mars (Williams, 2014). Imagine that you were able to move to Mars. In this forum, discuss some of the activities you engage in every day that would be dramatically different in lower gravity.

1. What would be the advantages or disadvantages? Would some of your daily activities be easier, more difficult, or even completely impossible?

2.If you could create your workspace in an environment with or without gravity, which would you choose? Why?

3. How would the gravity or lack of gravity impact your physical activity?

Explanation / Answer

(1) there will be more disadvatnges than advantges. eating and drinking water will be difficult.the speed of waterfalls from which we generate electricity will decrease and hence the electricity output will decrease.one of the advantages can be that the sportsperson can jump much higher with less effort.

(2) we would always choose the worspace with gravity. without gravity everything would be messy. things will float because of motion of earth if there is no gravity. we will also not be able to hold on to the ground in case of no gravity.

(3) with no gravity, moving around becomes easy. it will be easier to jump or rather we would keep floating. a disadvantage to having no gravity would be that you would lose bone mass and your muscles would get weaker over time.
