The Pros And Cons Of Human Space Flight

The National Aeronautics and Space Administration (NASA) is perhaps the most well known space agency in the world. Since its formation in 19581, it has pioneered in space science, yet is also renowned for its large budget. NASA has the highest budget of any space agency, $18.6 billion2 in 2015, the equivalent of every American paying $54 towards the agency3, meaning 0.14% of total GDP is spent on NASA3 . This money is spent on the ISS, sending astronauts, probes and satellites into space, astrophysics and planetary science research, maintaining and developing NASA’s space telescopes (the Wide Field Infrared Survey telescope searching for dark energy and exoplanets, the James Webb Space Telescope and the Hubble Space Telescope) and developing spacecraft2. Space exploration is an incredibly expensive process with one shuttle launch costing $450 million4 however NASA’s colossal budget benefits the USA greatly; the agency employs 18,000 people5 as astronauts, engineers, scientists and teachers and G. Scott Hubbard, former director of the NASA Ames Research Center estimates that every dollar spent on NASA returns $8 to the economy6.While this figure is an estimate, it demonstrates NASA’s worth and capacity for money making. NASA works on pioneering research and as its patents and licenses return to the US treasury, it

Our bodies are not built for space. The exposure to radiation can cause cataracts, brain damage, and cancer. Weightlessness can cause muscle mass loss, bone mass loss, and bad circulation. Author of "Humans may dream of traveling to Mars, but our bodies aren't built for it," Charles Wohlforth and Amanda Hendrix explains "Doctor-astronauts working on the International Space Station in 2009 also discovered that living in weightlessness can damage the optic nerve. In the absence of gravity, cerebral-spinal fluid stops circulating. On voyages of more than a year, that could lead to blindness or contribute to dementia," [3]. This is a big problem when it comes to space travel, and should be NASA's biggest priority.

One of the ultimate goals of space research and space travel is to put human beings into space, be it for deep space research, recreation, or colonization. As we develop new technology and plot a course of action to progress towards this goal, one of the factors that cannot be ignored is how the human body reacts when in space for a long time. Both speculative projections from experienced scientists and actual research done by NASA suggests that the situation is a lot more complicated then just sending people into orbit with enough food and water to keep them alive. The human body developed on earth, and is very fragile when put into the hostile environment of outer space. There are a number of prominent

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.

“One small step for man, one giant leap for mankind,” said Neil Armstrong, the first man to be on the moon. Mankind has benefited so much from the Space Race. The Space Race was a Cold War competition between NASA and the USSR to reach the moon. The Space Race took place from 1957 up until 1975. On May 26, 1961, President Kennedy laid the Soviet challenge before the American people. During the Cold War, around a hundred space advancements were made. In the 20th century, more space breakthroughs happened after the moon landing itself. A few more moon landings followed Apollo 11. The Space Race had a positive effect on the world. Before the Space Race, most of the space exploration had been done by robots (Miller

Space exploration has exploded in the past 56 years. From the first successful satellite mission in 1961, to the first mission space walk in 1969 a to the first time lettuce was grown and eaten in space in 2015. These are just the beginning steps towards potential space exploration and advancing technology to the maximum.

The Space Race was a time of great exploration, and created many new techniques in the studies of science and technology. Many new techniques of engineering and technological advances resulted as positives of the Space Race. The cause of this great exploration and learning was fueled by rivalry and competitiveness of two governments, the Soviet Union and The United States. The Soviet Union and the United States were in a race to see which could reach space supremacy first. This rivalry unfolded in front of millions of spectators, and instilled a sense of competiveness into the viewers. During the mid nineteen-sixties, the achievements of the United States space program caused them to leap ahead of the Soviet Union space program, which was very unexpected. The achievements by the United States during the Space Race in the nineteen-sixties created a gap in space exploration between the Soviet Union space program and the United States space program because the United States was able extremely motivated by government forces and was able to achieve great technological advances in their space crafts.

College is the pinnacle of any education known to humankind, the sanctuary of knowledge, and the birth of new ideas and idealists. Since the University of Al-Karaouine was commissioned in 859 A.D., colleges have expanded their range of teachings from mathematics, physics, and foreign languages to many diverse fields that deal with nearly every aspect of today’s world. More academic institutions were established over the next millennia, but only a privileged few would be able to attend the schools of Paris, Oxford, and Montpelier. In addition to beneficial education in particular fields, colleges offer positive factors for their students. These factors include building relationships with students and professors while improving one’s standing

I did the article of S.T.E.A.M it was about how we need to improve on it because it’s going to be very important in the science world because it is so open such as the space race till this day and we are still against other countries in the world. A lot of it was talking how now this is a course in school that kids take to get ahead in the classes.

SOCIAL WHEELS AND SPACE RACES When we talk about recent innovation, social change, industrial change, what pops into most of our heads is “space technology”. Gps systems, wifi, the moon landing, and probes all fall into this category. But how did all these interstellar wonders appear into our everyday life? What pushed our civilization to expand out tech beyond the sky.

Elon Musk, founder of SpaceX, has been trying to get a manned mission to Mars since 2002; it was the reason that he started his own business to build and improve on rocket technology.

Space exploration is the future of humanity. As technology improves, new solutions arise to answer the question of sustaining life outside Earth. Many types of life support systems are developed and used on regular missions. However, determining the most suitable life support system for missions on Mars presents a challenge that this paper will solve. This article compares different life support systems using the Equivalent System Mass (ESM), which measures the relative cost of hardware based on its mass, volume, power, and cooling requirements. Bioregenerative systems are more practicable and secure for longer missions as they avoid the cost of constant food supply. However, the ESM shows that the higher initial cost of bioregenerative systems makes it way more expensive than the Physical/Chemical systems for long-duration missions. For short duration missions, the least expensive life support uses direct provision of water, oxygen and food from Earth. As Mars missions aren’t brief, the physical/chemical life support system is the most suitable. The ESM breakeven analysis confirms these well-known and widely accepted results. The conclusion makes the substantial past efforts to develop bioregenerative life support appear impractical.

Mankind has always been fascinated with exploring the unknown. From sailing to distant lands to someday setting foot on other planets, the spirit of exploration is the same. Bur now with the current economic situation and the high cost of sending people to space, NASA is being looked at as a way to free up some much needed funds. Although, there is many problems here on planet Earth that need addressing, the benefits of space exploration far out weight the disadvantages. Space exploration has given us more advanced technology, advances in the medical field, and a boost to the economy and these facts cannot be disputed.

The mysterious vastness beyond Earth has allured many scientists to explore and contribute much of their effort to the understanding of space. Although humans have been looking up at space for thousands of years, the physical exploration of this frontier has been only going on for the past few decades. Our current understanding of space is unparalleled to any time before in our history, but we still only know a small fraction of what there is to learn. Governments around the world spend about $40 billion dollars a year (Rockefeller, 2010) hoping to undertake tasks such as “human exploration of the solar system” to discovering the origins of life itself (Tatarewicz, 2009, p. 531). Recently, the private sector has also shown interest in space exploration in order to engage in profitable activities such as harnessing minerals from asteroids. Although it is easy to debate about the benefits and negatives of space exploration in its entirety, it is simpler focus on one aspect of it - the direct effect it has to those down on Earth. Rather than trying to decide whether or not going to other planets is worth it, this paper will argue about the value of the terrestrial benefits of space exploration. It is an important topic to think about as programs such as space exploration change lives and help acquire knowledge. Despite the large costs associated with space exploration, the multitude of discoveries in the past few decades has greatly improved daily life on Earth, the jobs the

This peer-reviewed journal article talks about the positive consequences of developments in future space exploration in scientific perspective. The author states the development of future space exploration by using resources from the solar system will produce varies beneficial results, such as space tourism, asteroid resources, and so on. The main beneficiary among all the others is science. Supported by space resources, the growth of space economy can provide the cost of building scientific instruments, outposts, and infrastructures in space. Improvement in scientific technology leads to further discoveries and knowledge. Which shows the symbiotic relationship existed between science and space resources.
