Long Term Space Travel And Its Effects On The Human Body

Long-term Space Travel and its Effects on the Human Body Synopsis: Humans are planning more space missions to Mars and deeper into the solar system. These manned missions require longer periods of time in space than any human has ever spent, as well as traveling farther from Earth’s protection than ever before. There has been very little research conducted regarding the effects of prolonged space travel on the human body. This paper examines how space travel will likely alter bodily functions. The evolution of life on Earth means that humans are adapted and specialized to live and function in Earth’s environment. The environment of open space presents hazards such as: solar radiation, microgravity, and extreme isolation. Prolonged exposure to these hazards could result in cardiovascular issues, cancers, cellular disruption, decreased bone density, osteoporosis, psychological issues, and more. It is important for scientists to research these hazards and their effects on the human body further so as to find solutions and ways to combat the negative outcomes. Exploration is a key component of human nature. Humans have always had the will to venture out into the unknown and explore new world. The curious and adventurous nature of mankind colonized the Earth and landed men on the moon. But what is the next step? How much farther can man go? Humans are looking past the moon, to the stars and beyond now. In the past decade, multiple spacefaring governments and corporations haveShow MoreRelatedThe Feasibility of Prolonged Space Travel1363 Words   |  5 PagesThe Feasibility of Prolonged Space Travel My scientifically accurate sci-fi paper will focus on long term space travel on a future mission to a distant exoplanet, such as the recently discovered Kepler-186f, that is thought to be habitable for human life and later colonization. The astronauts travelling to the exoplanet will have to deal with the effects of space travel such as radiation on their bodies, both physically and psychologically.

This occurs because of the decrease in amount of nitrogen and oxygen molecules that are used to populate the air. This alone has tremendous effects on the human body, not just physically, but mentally. In the 1950’s, a major concern of those involved with space research and travel was a psychological problem, called the â€Å"Break-OffRead MoreEffects Of Long Term Space Flight1578 Words   |  7 PagesResearch Topic: Effect of Long-Term Space Flight How long would a â€Å"long term† space flight be?

However, despite the number of attempts and robotic explorations made to Mars, we have yet to send humans to this red planet.

Biomedical complications disrupt any advancements in the effort, as astronaut safety is considered the most fundamental aspect of a successful mission. In order to study the effects of weightlessness and radiation in a deep space environment, NASA launches a government funded space station into high earth orbit.

Some of the most prominent threats include loss of muscle mass, decrease in bone density, and weakening of the immune system. Other dangerous potential effects are alteration in circadian rhythms and exposure to radiation. Each effect either has current treatments, or are currently being researched to discover more effective forms to combat the potential dange rs they pose.
