What goes up, must come down! Dr Niamh Shaw explains why in this Space Hub and tells us about gravity on earth and other planets too. Plus, Niamh talks about how living in space isn't really good for our bodies.
One of the fun things Niamh talks about is how our bodies would feel if we were to travel to other planets. How easy or difficult would it be to just jump in the air?!
Check out this image from Nasa where they tell you how much you would 'weigh' on other planets if you were 100 pounds (45 kilos) earth.
On this link from Exploratorium in the USA you can enter your own weight in any units you wish, so go for pounds, kilos or even stones and you will get the answer.
And that's just the planets, she tells us how living in zero gravity can is not good for our bodies so they have to work out on special machines.
You can check out the International Space Station workout plan in this cool video from NASA!
NASA Commentator Lori Meggs talks with Gail Perusek of NASA's Exercise Countermeasures Lab at the Glenn Research Center about the exercises that keep International Space Station crew members healthy during extended missions in weightlessness and how the scientists design the hardware for use on orbit.
Resistance and aerobic exercises are vital to keeping the crew members healthy in an environment where they don’t even have to work against the pull of gravity in their day to day lives.
