Effects Of Long Term Space Flight

Space exploration is dangerous for human because it will take a long time and when you landed on earth you will have to adjust on earth again and

Radiation is one of the main forms of energy (Pettigrew 1). In today’s environment we are only familiar with the basic types of radiation. These types are in the form of

The collection follows the story of people from Earth colonizing Mars as Earth is demolished by a nuclear war and their experience adapting to Mars while witnessing the deterioration of their homeland. The novel was written in the 1950’s, when there was a space race between the United States and the Soviet Union. Furthermore, there was very little knowledge about planets other than Earth, and there had been many failed

For my original, scientifically-correct science fiction article that I will be writing later on this quarter, I plan to describe the dangers that astronauts face when traveling to outer space. Not only are there numerous unknowns that may arise as challenges, but there are very real health risks that must be addressed. Among those risks are the effects of long term space travel, and the lack of adaptation by the human body, as well as the high amounts of radiation that are present outside of the protection that the Earth provides. To better understand the radiation exposure that astronauts must deal with in space, I will define the risks of exposure to

While this is a deeply rooted concern for NASA, the organization plans to make progress in making human space travel safe and productive. In 2016, Former President Barack Obama wrote an article on CNN’s wire service with gargantuan hopes for the future generations of space travel to develop in the future. In the article entitled, “ America Will Take the Giant Leap to Mars”, Obama proposes that the United States will be capable of sending astronauts to Mars by the year 2030. To support his statement, he comments, “I’m excited to announce that we are working with our commercial partners to build new habitats that can sustain and transport astronauts on long-duration missions in deep space”(Obama 1). Here, Obama is acknowledging the fact that astronauts have been, and are, affected by radiation and loss of gravity when exposed to “deep space” for long periods of time. He is also revealing that through years of research and development, the government is prepared to safely send America’s astronauts to other planets for the purpose of exploration and advances in many technological fields. Yes, astronauts’ health

As days progress, the martian way of life gets buried even deeper by the sands of time. Ruins remain ruined, and earth men erect buildings, houses, and towns. Mars is becoming an emblem of hope for the people effected by the conflict on earth, much like America, was an emblem of hope for the oppressed pilgrims.

From 1961 to 1972, the government-funded organization NASA ran the Apollo program, which attempted to land humans on the Moon and bring them back to Earth safely. Of the program’s 16 successful flights, five flights landed men on the Moon and a total of twelve men walked on the Moon. Samples taken from the Moon’s surface paved the way for enormous discoveries and increased understanding about space, natural elements and our Moon’s composition. However, one aspect of discovery that the Apollo missions enabled was the discovery of the human body’s reaction to space and weightless environments.

The Martian is the story of an astronaut named Mark Watney who is part of a crew that is the third team of astronauts to go to Mars. Watney is a botanist and mechanical engineer, and starts keeping a journal in hope that a future archaeologist will

Missions to space pose a great risk on astronauts. Space exploration risks human life. Staying in a spacecraft is not easy, the conditions are harsh, and making the survival during space travel is a challenge. The effects of radiation on the body and bone loss are all a risk that you must take to go and explore in space. According to the website NASA, “The human body is

How long would a “long term” space flight be? According to our records, the longest that human has been off Earth is almost 438 days, and it is the mission operated by Russian space station Mir. (Beings not Made for Space, Kenneth Chang, 2014) Long-term space flight requests that astronauts have to be exposed to the real space environment, which includes microgravity, the significant increase in radiation, variation in temperature and space view. Due to these changes of space environment from that of the Earth, astronauts will face the changes on their body and health, some of the changes would be negative. For example, astronauts will see the significant changes in their body; their whole bodies will expand, the mass of their bones and muscles would lose, and some of them might have farsighted eyes. To build a better space environment, scientists have been working hard to find out what is causing the health issues and ways to solve them. They have done well-known researches such as “Twins Study” between Mark and Kelly Scott. The latest technology that involved is called artificial gravity; it is considered desirable for long-term space flight as well as human habitat in space.

Although, it is dangerous for the humans that go and explore space, as there are many things that can go wrong and there many dangers for astronauts in space, space exploration and the space program has lead to many advances in science, technology and more. In fact, the article “Benefits Stemming from Space Exploration” stated “Overcoming the challenges of working in space has led to many technological and scientific advances that have provided benefits to society on Earth in areas including health and medicine, transportation, public safety, consumer goods, energy and environment, information technology, and industrial productivity.” The technological and scientific advances that have come out through the space program have greatly helped society in many ways. One way that the space program has helped people is in the area of health and medicine, because of the space program inventions such as artificial limbs, and infrared ear thermometers have benefitted people all over the world. Next, In the article, “Technologies Benefit Our Lives”, it says, “NASA’s continued funding, coupled with its collective innovations in robotics and shock-absorption/comfort materials are inspiring and enabling the private sector to create new and better solutions for animal and human prostheses. Advancements such as Environmental Robots Inc.’s development of artificial muscle systems with robotic sensing and actuation capabilities for use in NASA space robotic and extravehicular activities are

It can also jeopardize the functional performance when adapting to a novel gravitational environment in an acute phase. Some researches have indicated the changes in manual control, visual performance, spatial orientation and gait control after space flight missions, and the greatest changes usually happen immediately after the astronaut experience gravity transition. Also, it is shown that the longer the time of the flight is, the larger possibility of post flight disturbances

Since NASA’s inception in 1958, more missions have been attempted to Mars than any other place in the solar system besides the moon [1]. However, despite the number of attempts and robotic explorations made to Mars, we have yet to send humans to this red planet. Explanations for this lack of human presence can be attributed to the obstacles faced by scientists; from the technical issues that need to be overcome, to the sheer expense, there is also the challenge of knowing how long-duration space travel can affect astronauts not only physically but also psychologically. My sci-fi story shall give a glimpse into a crew’s round-trip to Mars and the challenge to achieve their mission’s goals and whether the physical and mental wear on their bodies will prevent them from doing so.

The fascination with space is as old, if not older, than the human species itself. Humans have developed the capacity to begin to explore this realm in the twentieth century which represents a flash in the course of human evolution. Furthermore, through the process of natural selection, homo sapiens have evolved under a specific set of physiological constraints. These constraints have shaped the process of human development however they are not present in the same composition in space. Therefore there are many implications for the physical aspects of space travel. There will need to be many developments in the science of physiology in this frontier before long duration flights, such as a trip to Mars, becomes feasible. This analysis will provide a literature review of some of the issues regarding human physiology in this realm as well as one of the more fascinating microorganisms who have shown to be able to withstand some of the adverse effects that space can inflict upon them.

America has reaped the benefits of space exploration for sixty years, despite the open knowledge of its effects on those who enter radiation and low-gravity environments. A low gravity environment is a space in which gravity, an attracting force between two masses, is lowered in a way that causes a feeling of weightlessness (Newman, Phil. “What Is Gravity?”). Lowered gravity can cause gene modification and alter behavior (Shikawa, Chihiro, et al. "Effects of Gravity Changes on Gene Expression of BDNF and Serotonin Receptors in the Mouse Brain."). It can also induce osteoporosis, an incurable disease increasing the susceptibility of bones to fracture ("Osteoporosis."), causing astronauts to lose 1-2% of bone mass per month in space (Bones, Space. “Space Bones.”. Radiation (from space) is a type of ionizing radiation that releases energy when it occurs. When that energy is released, it can be absorbed by living tissue, which can cause irreparable DNA damage (Cucinotta, Francis A. "Space Radiation Risks for Astronauts on Multiple International Space Station Missions.").
