Authors Note:
This is an essay talking about the difficulty astronauts have living in a micro-gravity environment for long periods of time. Please notice my use secondary sources noted at the bottom.
Imagine
the world is floating, every task you try to do your weightless, your whole
world is literally turned around. This is what it is like for people living on the
international space station also known as the ISS. Everyday tasks become a
challenge like eating, brushing your teeth, working out, and even going to the
bathroom because they all require special equipment and skills.
The
ISS is an important feature to the exploration to the atmosphere around
us. On the ISS they can find ways to
predict weather more effectively, see where to clean up pollution and oil
spills, and find lots of ways to improve our life on Earth. (The Space
Operation Learning Center). In total, more than 400 scientific experiments in
fields such as biology, human physiology, and physical and materials
science, have been conducted on or in
the space station over the last decade. (Is the International Space
Station Worth $100 Billion?) They also use this
facility to see how peoples body’s adapt to living in a microgravity for long
periods of time.
Now
getting to how people live on the ISS, when they wake up the first thing they
do is get up and go to the bathroom and brush their teeth, seams simple but
it’s really not. To brush your teeth on the ISS, you first take a sip from a
bag with a straw but don’t swallow, then
grab your tooth brush and your tooth paste and you brush, when it’s time to
spit you have to do it differently. If you spit into a sink your spit would
just float everywhere in the air so instead you spit into a Kleenex then throw the Kleenex away. (The Atlantic, How to brush your teath on the
international space station). Since there is no
gravity to either hold a toilet bowl full of water in place or pull a humans
waste down, the toilets are much different in space. Although it is designed to
be as much as possible like those on Earth, there are a number of changes.
Straps are there to hold feet against the floor, and pivoting bars swing across
the thighs ensuring the user remains seated. There is a hose, which can be used
in a standing position or can be used sitting (Space/Astronomy).
Although
getting up, brushing your teeth, and going to the bathroom are all a key point
in life you need food to survive! On the ISS there isn’t a refrigerator and
since you’re in space for a long time the food you eat can’t perish you have to
eat a special kind of food. The food they eat is like the food you would take
camping for a long time. It has to be something that can cook by just adding
moisture. According to Irene Klotz of the Discovery Channel website, some of
astronauts favorite foods include Japanese takeout, Sweetish meatballs, yogurt,
chicken soup, tortillas, shrimp, hot
sauce, M&Ms, dried produce, and mystery meals. If you want salt or pepper on
any of those meals you can but they are only available in a liquid form. This
is because astronauts can't sprinkle salt and pepper on their food in space, the
salt and pepper would simply float away and that causes a danger that they
could clog air vents, contaminate equipment or get stuck in an astronaut's
eyes, mouth or nose (The Space Operation Learning
Center).
There are many reasons why you must
work out in space. Since astronauts are in orbit around the earth they don’t
feel the effects of gravity there for they don’t have to use their muscles as
much doing normal everyday things
(Rothstein).
Because of that they have to work out with special equipment to prevent muscle atrophy, a condition
astronauts experience after long periods of inactivity (The Space
Operation Learning Center). Muscle atrophy is a decrease in the mass of the muscle; it can be a partial
or complete wasting away of muscle (Merrian-Webster). So because of that astronauts exercise two
hours per day. Lifting 200 pounds on Earth may be a lot of work, but in space
it is easy, the 200 pounds appear to weigh nothing. Therefore, exercise
equipment needs to be specially designed for use in space so astronauts will
receive the workout needed.
One way they prevent muscle atrophy
is by using a piece of specialized equipment call an Advanced Resistive
Exercise Device or aRED for short. This device acts like a weight machine but
it doesn't use weights at all, instead it has a system of vacuum cylinders; canisters with air that have
had a vacuum suction that provide up to
600 pounds of weight (Landau). When you’re using this
device it is kind of like a bicycle pump only in reverse. So if you squat the vacuum
compresses and then when you stand back up the vacuum sucks air into it and as
a result puts strain on you as you try to stand back up making it a effective
workout (Landau).
Every
kid in the world had a dream occupation they wanted to be weather it was a
fireman, a police man, or a doctor but in 2013 it was reported that astronaut
was the second highest ranked dream job of kids across the world (Share Ranks).
For all the kids and adults out there that want to be an astronaut just
remember that you could live on the ISS and help the development of space
exploration.
