One Paragraph Synopsis of the Paper:
Not very long ago, I was taking space and space travel at the University of Washington. I still remember the basic lessons I learned. I believe I graduated around twenty to twenty one years ago by now but there is no point in counting. College has become irrelevant in my career. Frankly, having a career has become irrelevant for most of my peers. I believe I read recently that the United States has reached a new high in unemployment, again. With technology capable of rebuilding its self and improving its self progressively, it won’t be long till people leave the solar system. I give it another twenty years. Today, though, I finally made my decision. It’s

For this reason, the human body’s fluids rely on gravity to move downward to the lower areas of the body, such as a person legs. In microgravity, a person is no longer experiencing earth’s gravitational pull as one would experience it on the surface of the earth; therefore, their fluids are redistributed to the upper part of the body. The astronaut will start to experience a puffy face, congestion, nerve swelling, retinal changes, and an increase in intracranial pressure. To prevent this, NASA has guidelines for us to wear Chinibus LBNP (lower body negative pressure ) suits. These suits designed to provide gravity simulating stress to the body’s cardiovascular and circulatory system. The body interprets the pressure differential between the upper and lower body as a gravity like force. These suits help the body continue to distribute fluids as it would on earth.

The astronaut’s circadian rhythms and their light-dark cycle are thrown off rhythm. For example, on the international space station an astronaut would experience another dawn every 90 minutes. This is much faster periods of light and dark than earths 24 hour cycle. (The Effects of Space Travel on the Human Body)
NASA has installed bulbs on my space craft to minimize sleep deprivation. The bulbs mimic a twenty four hour cycle on earth. A 24 hour cycle will help regular many body processes including sleep patterns. In order to precisely mimic earth’s night and day cycle, the bulbs are also designed to shine different wavelengths of light later in the day to approximate what happens as dusk approaches earth.
