Human Spaceflight: The Benefits and the Disadvantages

For many years humans have been exploring space to discover the unknown and fuel their curious and adventurous nature, but the decision of whether space exploration is worth the cost is strongly debated. Due to various arguments and evidence space exploration is strongly supported is proven to be worth the cost. Some of these reasons include space exploration being able to expand our knowledge and it being able to generate wealth. With these reasons the argument of whether space exploration is worth the risk can be easily decided.

It is not true that human space travel is cheaper in any sense; life support systems, places to sleep and work, manual control systems all take up room, and most importantly, cost fuel. However, when it comes to planetary exploration, humans can get the job done better. They adapt to the situations they’re put into. A robot can only do everything it was told it was supposed to do, but programmer bound to the Earth will only think to program so many things, even if they are very thorough. Robots movements encompass a narrow set of navigable terrains whereas a human with mobility equipment can explore much further to garner samples or collect data (Crawford). A human can also think on their feet, which is essential in many mission scenarios. Far from the earth, where communication is severely limited by the distances involved, robots lag the humans watching. Events that occur for only a few minutes, like storms and novel hazards like rockslides or avalanches, may be completely missed by a rover and can even compromise the mission. When delay inhibits data collection and the safety of crucial components, this is where on-site humans can shine. Specifically, Crawford (2010) outlines five areas where human travel is necessary, which for brevity has been condensed into four. The focus is mainly on why humans are essential for these types of missions.

The purely scientific benefits of space exploration and research have been vast. These advancements have influenced everything from communications, earth sciences, weather prediction, astrophysics, astronomy, planetary research (Moon, Mars, etc.), archaeology, solar research, asteroids and comets, environmental sciences, and medical science. The world today would be a poorer place without the scientific advancements achieved through space exploration and research.

Carl Sagan once said “every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds.” The National Aeronautics and Space Administration or NASA, is executing Sagan’s words every day. President Dwight D. Eisenhower created NASA in 1958 with the purpose of peaceful rather than military space exploration and research to contribute to society. Just 11 years after the creation, NASA put Neil Armstrong and Buzz Aldrin on the moon, the first humans to

Although space exploration is now being emphasized on and invested in, what does this do to benefit earth or even every individual who lives on Earth? Many writers, engineers, mathematicians, and chemists can agree that space exploration is going to provide more research for medicine and environmental factors. Others may also argue that the risks of exploring another planet will be too damaging because the life or atmosphere as it is will not be the same after humans have made their print on it.

Space has always been an unknown to the humanity, and therefore humanity has in insatiable desire to know as much as possible about the area beyond the Earth's atmosphere. Exploring space can lead to many new and exciting discoveries such as (see hubble, planets, kepler, moon rocks etc). When the United States first entered the realm of space in the [1960s], NASA had much funding. However, the motivation of this funding was not for science – it was political, as the government was determined to beat Russia in the Cold War Space Race. Today, as there is no political motivator as great as the Cold War, NASA is faced with a lack of funding and must make hard decisions. They must decide between the adventure and excitement of sending manned missions

Space exploration funding has been drastically reduced since the conclusion of the Space Race. Even though the Space Race is no longer relevant, it has positively affected human civilization, and we should continue to invest in space exploration to continue this trend. The first and primary reason we should continue to work with space is to aid industries on earth. Most notable is the use of satellites for purposes such as commercial communications, the GPS system, and meteorology. The second reason is because humans have an inherent hunger for knowledge, and space funding helps us develop technology for seeing what’s beyond earth. Space probes such as New Horizons and telescopes such as the James Webb Telescope have expanded our knowledge

The first reason exploration is worth the risk is medical research. Medical research is very important and John F. Kennedy couldn’t have explained it better. Stated in Remarks at the Dedication of the Aerospace Medical Health Center “Examinations of the astronaut’s physical, and mental, and emotional reactions can teach us more about the differences between normal and abnormal.” This evidence shows that space exploration could help us tell the difference between normal and anomalous. Another thing that Kennedy greatly stated in Remarks at the Dedication of the Aerospace Medical Health Center was “About the causes and effects of disorientation, about changes in metabolism which could result in extending the life span.” So this evidence shows that space exploration could help us extending the human

This worked out exceptionally well as NASA helped quite well through the usage of the research and the Apollo program. With the use of this exceptional program, for the first time in man-kind history, people had left Earth, orbited it as well as, to a great surprise, had also landed on the moon. Overall these trips, especially the ones involving human beings travelling in space, continue to help NASA and scientists investigate further.

The amount of accomplishments America has achieved in the area of space research is staggering. We have sent man to the moon, landed rovers, and discovered uncountable celestial bodies just by telescope! There are many benefits of space exploration, making it absolutely worth the cost. Some of these benefits are creating new beneficial jobs, and expanding our knowledge. While some argue there are drawbacks to space exploration, I think that the benefits outweigh these drawbacks. In addition, we desire to explore the unknown. As Georgia Douglass Johnson said the the poem “Your World”, in stanza 1 “Your world is as big as you make it”. This means that we can do whatever we want, as long as we’re determined.

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.

You hear a lot of people saying that space research is cool but it is typically a waste of money and valuable resources that could be used to benefit our own planet and the many problems that we have all over earth today. But I completely, one hundred percent agree on the further exploration of space for different reasons such as: we are living in a virtual age where everything is done with smart phones and computers and physical exploration is much needed. Second it can actually help the economy in multiple ways not just waste money. Lastly It also guarantees the development of good technology, not only with companies, but among the younger people who need to be inspired through the educational systems we have in America.

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.

Humans have always been interested in space and the wonder in which it may hold. In the past, humans worshiped the stars as if they were gods while also studying their position to give them guidance for their lives. Their interested in space has fathered the desire to know more. Today, space has been seen by many as the new frontier or the home beyond earth. Society have even taken a step forward through the creation of stories in books and movies based of the idea of humans living in space and the present of alliances. Yet there is still controversy on the need to continue space exploration when our own planet has so many detrimental problems. There is an ongoing debate on whether not the money used for space travel could be better beneficially use for other causes. It is true that space exploration costs billions of dollars a year alone according to NASA current budget, which is constantly increasing. However, what many refuses to understand is that without space exploration many of the innovations that we have today would not have existed. While there have been, many failed attempts involving space exploration that has caused a tremendous amount of money to go down the drain. However, many people fail to realize the benefits of space exploration and the possible future it may
