Space Travel

Space Travel

Aerospace travel began on October 4, 1957 (Aerospace), and from that day onward, the world had changed. The planets, the stars, and the endless sky. There is nothing more like it. People look into the night sky and wish they were up there floating through space feeling weightless and free like nothing is holding them back. Space sounds like a dream, but a nightmare is folded inside. From effect to the body, isolation from family, and space radiation these are all effects of space travel.

The body works differently in space then it does on Earth. The microbes in space change the human body (NASA). Microorganisms can move from person to person; the percentage of passing of sickness is higher than it would be on earth.  So, when one person gets sick everyone else will get sick in the space shuttle as well. Also, human hormone levels are increased and the body immune system is changed(NASA). Because of this, the chances of getting sick or even diseases is greater. When NASA is picking their astronauts, the astronauts need to be in the best physical condition(NASA). While the human body is in space an astronaut starts to lose calcium, bones, and muscles began to shrink away(BBC). Bone loss can occur in space because the bones in the human body doesn't have to be supported in space. There is a lot that happens to the body while the human body is in space, but that is not the only problem. Think about being stuck with the same people for months on end.

Isolation is another big drawback in space travel; the person is far from their friends and family. If being isolated isn’t bad enough, the body also goes under multiple emotional changes. Some of the problems are a decrease in mood, cognition, morale, or interpersonal interaction(NASA). A person in space can also develop a sleeping problem which is occurred because the body circadian rhythm is changed or altered while a person is in space(NASA). Depression may even occur due to isolation while an astronaut is in space(NASA). Another huge risk for astronauts is space radiation.

Astronauts are being exposed to ten times more radiation than a human would be exposed to on Earth (NASA). Radiation exposure may increase the human risk for cancer (NASA). It also affects the body nervous system. Other effects to the body such as behavioral changes, cognitive changes, and lessened motor function (NASA). Astronauts can also suffer from radiation sickness, vomiting, and nausea, cataracts, cardiac, and circulatory diseases(NASA).

Space has a large amount of drawbacks such as  effects to the body, isolation, or space radiation. All these things may affect an astronaut during space travel does not matter to the moon or to Mars. Space is a dangerous world for the human body. Space is dangerous for all humans hopefully scientists will finally be able to make space a safer place for astronauts.

Follow your Heart

      "Sweetie come downstairs, you do not want to get late for your first day at your guitar lesson," said my mom.  "I will be there in just a minute," I said as I put on my clothes. As I sat sluggishly in the back of my dad's car I thought of how great the guitar lesson might turn out to be.        "Honey, are you excited? I have heard your teacher is very friendly," my dad said.  Once we got there I struggled to put a smile on my face. For some reason just looking at the place made me feel like I didn't belong there at all.  "Hi my name is Mr. Bowman and I will be teaching you the guitar," said my guitar teacher in a very fancy way.    "Hi my name is Hayleigh," I said trying to lift my hand to shake his hand. Looking at his hands I saw bristle and line marks. He said those marks were from the guitar strings.  Once we got started  I felt like I could doze off,  but it will show my dad that I never wanted ...

What the World Gains from Optimism

Image
Optimism changes lives!      Optimism is a character trait which many people have. Some people are pessimists, this means they will find a problem with every situation. While many choose to be in the dark, optimists choose to see every challenging situation in a new light. The world gains an immense amount from optimism… From people to technologies to hope there is no sight for what optimism can bring.  Being optimistic is the key to life!     Optimism and world peace go hand in hand. We always need optimistic people to change the world. If there was no Nelson Mandela, Abraham Lincoln, Mahatma Gandhi, or Martin Luther King Jr. this would be a very different world right now. For example, let's take Martin Luther King Jr. he was so optimistic, and he kept fighting for African-Americans rights. If these people were not optimistic we would not be living in the world we are living in right now. All these world leaders fought for a cause, and they changed t...
