Long Duration Human Space Flight Missions

The National Aeronautics and Space Administration (NASA) is one of the leading organizations in space technology and research. In the past 60 years, NASA has sent numerous satellites, telescopes and crew modules into space. Despite drawbacks in launch failures and lack of funding, NASA continues to focus on its mission in space exploration and technological advancement. One of NASA’s projects is to explore deep space, in which entails a manned missions to Mars, exploration of the asteroid belt, and beyond. With these goals in mind, NASA has engineered new rocketry and even created a program to better allocate costs of such conquests. With these new advancements, NASA has created a new age of how space travel is carried out.

Neil Armstrong 's 1969 lunar landing was one of humanity 's greatest accomplishments. Since then, we have found that an infinite supply of knowledge and resources await us just outside our atmosphere. Today, however, critics are beginning to argue more and more that the cost of space exploration is too high, and therefore new technological developments should be left to the private sector. Whether funded privately or by the government, funding of space exploration is imperative because NASA is essentially the only agency with the technological capabilities to support aircraft manufacturing, air safety and air transportation. Space exploration has also resulted in remarkable innovations that has played a key role in aeronautics research, preventative medicine, and allows scientists to study asteroids, along with other space debris and their impacts on Earth.

The space industry has produced many amazing technologies in the past from the development of fireproof material that makes up the modern firefighter suit to new forms of power generation. This is based on the fact that the National Aeronautics Space Agency (NASA)

Humans have dreamed of leaving the earth and traveling space for many years, and up to this day they have taken many steps in the right direction. Yet, with every new frontier they approach, new problems loom over the horizon. Some of these problems arise right here on Earth. Some of the issues have been resolved, such as escaping the forces of gravity to reach outer space. Most of the problems are far more arduous and the solutions need more time to be worked out properly. In “The Coming Schism” by James E. and Alcestis R. Oberg, they posit that humans can colonize space. Humans need to buckle up and build the technology which will help to solve problems that would arise to

The NASA space program has had enormous impacts on the world. Thanks to NASA the United States has explored thousands of celestial bodies throughout the galaxy with telescopes, rovers, and in the moon 's case, people. In the next decade, NASA plans to expand the United State’s human exploration to more than just the moon. A Mars mission has been in NASA’s eye for quite a while now and with technology advancing every day, they feel it is time to send men and women to the red planet. Some believe the journey could prove too dangerous for humans; however, through research and development scientists can find ways to safely transport astronauts to and from Mars. This is a necessary step in the country 's advancements in health, technology and

When most people think of NASA (National Aeronautics and Space Administration) and its Space Program, the first image that can come to mind is a giant rocket and outer space but far more is involved. NASA’s space program, and the need for major innovations to get man to space directly sparked a large number of spin-offs of space technology into some of todays important advancements, such as: water filtration, fuel cells, and technology that provides doctors a better way to scan patients for breast cancer. Modern water filtration for instance, would not be what it is today if not without the need to provide clean water to astronauts in outer space. What most people do not realize is, NASA benefits the everyday lives of people here on Earth

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. The major impacts that I will be talking about are microgravity and space radiation. 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. There will also be increase in risk of Alzheimer’s disease, damage in immune system and destroys of microbiomes. 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.

In his Remarks at the Dedication of the Aerospace Medical Health Center speech, John F. Kennedy made two cases clear: space medicine and technology will make life on earth healthy and happy, and that the U.S. should be a leader in space. These statements that he addresses are valid, as JFK himself provides his audience with orthodox evidence. Because of this sound data, his claims are genuine and believable.

Our knowledge of the long term space flight's effects on the human body is still limited, but we do have quite a bit of research done on the short term effects, which is necessary to know before considering the long term effects. These effects include but are not limited to blood

Since its conception in 1958, NASA has been a pivotal organization in innovative technology and space exploration. With inventions such as the Hubble telescope, or the space shuttle, NASA has provided the world with existential research regarding space. With a renewal of popular interest in NASA, the organization would be able to continue contributing vital research in the medical, and technological fields, as well as the future exploration of space as humans know it, and the future habitation of other planets.

Surviving in space and on another planet for a long span of time is a difficult task to accomplish. Humans require quite a bit of upkeep to stay alive, and when confined to small space shuttle it is difficult to provide all the necessities to survive. For the trip to another planet astronauts have to live in the space shuttle for a long duration. Strategies must be developed to maintain a livable habitat in the shuttle, and also when the astronauts reach the planet they will have to survive on the planet for a long period of time. There are many obstacles in the path of achieving habitability in space and on another planet.

Since the first space exploration in 1958, many controversial disputes have arisen questioning the necessity of space exploration. Some claim that space travel is simply not worth the risks regarding astronaut safety and economic costs. Others claim that the stars are a bridge for all nations, allowing us to solve problems, build wealth, and enhance life for people on Earth. Although space exploration has made a broad impact on the world we know today, I strongly believe that it is unnecessary to continue to fund programs involving space exploration when considering the extraordinary costs, unsafe conditions, and contamination problems which could potentially endanger us. Initially, manned exploration missions to space involved a greater amount

Due to the exponential increasing of human population and the limited resources availability, space colonization became a goal for the survival of human civilization and expansion of the human population. However, we have to acknowledge that we, the Earth’s living beings, have been evolving under the control of Earth’s environmental and climate changes, especially the effects of Earth’s gravity and exposure to sunlight, since 4100 million years ago. From a single-stranded of DNA to the formation of prokaryotes, the trials-and-errors of chemical processes created a stable and favorable system for us to live. For us, the human beings undoubtedly evolved from lots more obstacles and challenges. As a reminder of the ratio of size scale of Earth to Solar system, which is overwhelmingly large, the dangers and challenges would even be greater in million folds. Yet, the smartest and most creative living beings, humans, are going for this exploitation and exploration as an all-or-null challenge for future generations.

Cutting-edge science in space is currently done by probes and robots rather than human beings, such as the Mars rovers or the New Horizons mission. Human based efforts in space are now essentially limited to work done on the International Space Station, which many scientific communities find unnecessary or wasteful, especially considering their cost (Scientific American, Coates). These communities site various problems with the ISS, including the difficulty of conducting experiments because of vibrations throughout the station and the station’s need to vent gases into its surroundings (Scientific American). It is also prohibitively expensive for communities

6). With this approach, the scientists and engineers would create technology that would keep people safe wherever they went in space. “The capability-driven approach will usher in a dramatic series of “firsts” in space exploration. These “firsts” represent major achievements toward realizing the goal of a human presence throughout our solar system. NASA hopes to capitalize on the excitement generated by these achievements to inspire the next generations of explorers and scientists that will keep our nation on the leading edge of exploration, science, and technology” (Olson, 2011, p. 32).
