They have machines that they could do excersise with a treadmill and that is how thet stay in shape

# data[].attributes.body
Something i learned during this was that when you get to space you can feel sick and that if you don't exercise when you return to space you will be really weak.

# data[].attributes.body
I learned from the videos that you can lose up to 10 percent of your bones and most of your muscle mass while in space. That is why it is important for astronauts to at least work out once a an hour every so they do not lose that muscles mass.

Since there is no gravitiy in space you can just float with a sleeping bag while it mounted on the wall.

I learned that whenever there's a form of water in space, due to there being no gravity, it becomes a ball and the more water there is, the larger the bubble will be!

Most of the space-caused gene expression changes in Scott returned to normal when he returned to Earth but some still stayed even after 6 months

In space you can not eat and drink like you do on earth. Liquids like milk could float and get on things and could break them and make your kourne unsafe. So, instead they use little pouches of liquid and kind of like a gogo squeez with a straw so it doesn't go anywhere excent of your mouth.

Something I learned while reading about the NASA twin study is that when you are in space the bones in your spine spread out and they relax and that causes you to be taller. I also learned that you have to workout a lot in space so when you get back to earth you won't be super weak.

# data[].attributes.body
Something I learned is that when you get home, the gravity can feel like a car smashed on top of you. This make it so you have to relearn a lot of skills even walking.

# data[].attributes.body
I learned that when showering they have to use a bag of water and no rinse shampoo.

# data[].attributes.body
When coming back from space your legs are very weak and you can hardly stand up. Helping prevent this from happening is exercising. In space the average astronaut exercises 2 times a day. SO that when they come back it only takes a couple days to get used to earth again.

# data[].attributes.body
I learned that when you are in space it can make your body weak so you have to exercise for almost 2 hours per day.

White blood cells revealed genes, or regions of the genome, where DNA methylation was altered in flight but returned to baseline upon his return.

# data[].attributes.body
Astronauts have to attach themselves to something, so they don't float around and bump into something.

# data[].attributes.body
When you wash your hair in space, the water can be warm. You get the roots wet then you put leave in shampoo in it. Sometimes your water will try and escape and you can grab it and put it on your hair.

# data[].attributes.body
In the article NASA Twin Studies I found out that on the first couple of days being there, you feel nauseous, you vomit a lot, and you don't have your appetite. It basically was described as being on a rollercoaster because you're twisting, turning, and everything inside your stomach is floating around causing that.

# data[].attributes.body
In space, when you brush your teeth you can not run the toothbrush under a tap. You have to get a bag that is filled with water and than it will come out in a bubble and you put it on the toothbrush and that's how you brush your teeth. When you are done you have to swallow the toothpaste because there is where for you to spit the water out.

In space, since there is no gravity, weightlessness is a problem many people have to go through. It may sound fun, but it's not. In fact, it can cause loss of strength and loss of muscle, which can impact your health.

# data[].attributes.body
I found in space it can cause your spine to stretch, because of the no gravity you can grow up to 2 inches.

# data[].attributes.body
In space the water that gets evaporated from anything evan washing your hair gets collected in the air conditioning system and goes threw a process that turns the evaporated part of the water back into fresh clean drinking water.

# data[].attributes.body
Your muscles get weaker quicker in space hence the reason astronauts need to exercise more than usual. Muscles get weaker quicker because of zero gravity. Your muscles don't have to contract or work a lot in space.

A lot of people feel sick so they have to throw up in special bags.

# data[].attributes.body
I learned that you feel really sick when you go to space because like your body, and everything else in space the food in your stomach is floating around causing you to feel nauseous and queasy.

There was a ton of interesting things I found along the way of reading the Nasa Twin Study and the others but one thing that really stood out for me was how space impacted their genetics ( a change in telomere length dynamics during spaceflight specifically).

# data[].attributes.body
On average 6-foot astronauts gain 2 inches of height in space due to their spin decompressing. I feel like this is interesting because I wonder how much taller humanity will be when we live in space full time

A mesmerizing fact is when you cry your tears begin to form a bubble of water and run all over your face and not float into the atmosphere. I think this is cool because I know that water floats in space and ultimately your tears don't!

# data[].attributes.body
I learned that being in space does not affect you mentally.

# data[].attributes.body
I learned that space doesn't affect your physical health. all astronauts that stay out of orbit all recover from there space expedition making a space expedition to mars possible.

# data[].attributes.body
I learned that in space, you can't eat certain foods because of their texture, for example: bread makes crumbs so in space, bread is substituted with tortillas, so crumbs don't float away.

# data[].attributes.body
You can experience a change of tolomere length dynamics (basically the tissues of your chromosome)During spaceflight during the days of your landing.It happens due to the changes that your body faces in space that confuses.

# data[].attributes.body
I learned that there was two twins one went to space and on stayed on earth

# data[].attributes.headline
Drinks come in pouches because if they came regularly  it would float and damage something same with their food it comes in pouches.

Did you know that you could choke on water in space because there's no gravity. since there's no gravity the water floats down your throat instead of just going straight down.

# data[].attributes.body
After you come back to earth everything feels weird! if you lift a 4 month old there basically the same weight as a bed to some because everything in space were light weight.

# data[].attributes.body
A fact is that from the twins study, someone who has experience of being in space of a couple of times, their body adjusts, and they don't get the boning effects, body weakness and etc.

# data[].attributes.body
Food in space is sealed in an airtight bag so it can be good for up to 18 months.

# data[].attributes.body
One interesting fact that I learned is that astronauts bodies adapt to environment in space and will have to learn how to walk agian.

# data[].attributes.body
I think the most fasnating fact is that astronaught mussels become weak over time due to low gravity

# data[].attributes.body
That when you cry it stays in a little bubble and moves around your face until you dry it up with a towel.

# data[].attributes.body
One fact I thought was interesting was that being weightless is not as fun as it seems and can cause sickness and problems in the long run.

# data[].attributes.body
When you want to eat something in space, you would need to adapt to something due to zero gravity. An example of this is if you want to eat a sandwich, you would need to substitute it with something like a tortilla because when you eat the bread on a sandwich, the crumbs would fall onto the ground, but in space, it would just float up.

# data[].attributes.body
One interesting fact I found was water in space. There is no gravity so it forms a ball and floats around. They usually keep it in straws and pouches so it doesn't float around.

# data[].attributes.body
In one of the videos they talked about how astronauts sleep. They sleep on the walls, strapped to a sleeping bag.

# data[].attributes.body
When/if you cry in space the tears don't fall off your face. It forms a bubble of water on your face, and gets bigger as more tears come down.
