Thesis Statement On Space Exploration

14 Strikingly Fascinating Pros and Cons of Space Exploration

Space exploration invokes the interest of many. The possibility of finding life in extraterrestrial space leaves us mystified. While some believe that space travel and research in the field has advantages, there are others who criticize the field for having no real benefit for mankind. What are the pros and cons of space exploration?
"Of course risk is part of spaceflight. We accept some of that to achieve greater goals in exploration and find out more about ourselves and the universe."
~ Lisa Nowak, American former naval flight officer and NASA astronaut
We plan vacations to faraway lands. But how would it feel if we could plan a vacation to Mars? Won't it be exciting? Although it sounds unbelievable, it may turn into a reality. Thanks to space exploration, we might be able to find a planet where life can exist, or we may even discover extraterrestrial life. But these are only possibilities. Is the expenditure of money and resources on space travel really worthwhile? Here we discuss the pros and cons of exploring space.
▸ Space exploration can help us gain knowledge of other planets, stars, and celestial bodies. It has the potential to resolve mysteries of the outer space. Somewhere in space, we may find life. We may discover completely different life forms on another planet that supports life. Or we might find a planet that can sustain life. We may even find new human-like species, or aliens who are more developed than us. Exploring space may lead us to the discovery of an all-new world.
▸ Space research has the potential to bring changes to our living by introducing developments in science and opening doors to new information. In fact, space exploration has already benefited us in many ways. Satellites help locate minerals and fossil fuels. We have been able to harness solar energy due to our knowledge of the sun. Scientists are trying to understand if the process by which heat and light energy is produced by the sun, can be replicated on Earth to generate energy for human use. Through space exploration, we may be able to find new energy sources. This field paves the path for the study of cosmic radiations and their effects and uses.
▸ Satellites help us in forecasting weather and in predicting natural calamities. Satellite communication, TV, radio, and GPS are among some of the very important advantages of space exploration.
▸ Our understanding of the Earth has increased due to space exploration. Scientists are able to study the Earth's atmosphere from space and understand the changes in climate and their effects on the life on Earth. A pro of space travel is that it is possible to observe our planet from a distance. Satellites help the scientists assess how well and for how long our planet will be able to sustain life. Changes in the environment, and issues like global warming and ozone depletion can be studied. Space exploration has helped answer questions like how the Earth was formed or where organic materials come from.
▸ By exploring space, scientists can now know when an asteroid is going to pass close to the Earth's orbit or whether there are chances of it striking our planet and the harm it may cause. Asteroids that may threaten life on Earth can be mapped, thanks to space research. And scientists have even been able to devise ways to prevent the impact of asteroids by diverting near-Earth objects away from Earth.
▸ An important benefit of space exploration is that this field creates jobs. Organizations like NASA have thousands of employees. Space programs create employment. Space exploration involves both astronomy and space technology. The fields create work opportunities for not just astronauts, but even scientists and engineers who work on unmanned spacecraft, astronomers who study objects in space, and professionals who work in designing and testing space equipment.
▸ Space exploration whets the human appetite for adventure. Those willing to risk life for that 'out of the world' experience, quite literally so, obtain the relevant education and work with a space research organization. They participate in space studies and some of them even have the opportunity to travel to space. Space exploration satisfies the human desire of adventure and accomplishment.
▸ Space research needs the use of high-end technology, including specialized communication devices, small computers, robots, and other space equipment. Thus space exploration has the potential to drive innovation.
▸ Space exploration programs can help achieve cooperation between countries. Different nations come together in the pursuit of a common goal. When space research agencies come together, resources and expenses are shared and the research costs do not burden just one country. Space studies bring researchers from different parts of the world together, thus achieving a sharing of knowledge and co-operative effort.
▸ One of the most important cons of space exploration is the money spent on research. Space travel is very costly. The research undertaken needs the implementation of advanced technology, further adding to the costs incurred. Due to time that needs to be invested, and that when compared to the outcome, the research does not prove to be cost-effective. The cost of education for this field is also very high. The money that is spent on space exploration can rather be spent to reduce poverty in the underdeveloped countries. The national wealth can be channelized towards the betterment of the downtrodden lot of society. A huge amount of money is required for traveling to space. Critics of space exploration argue that it is not right to spend money on something like space research when several people on the planet are unable to meet even their basic needs.
▸ Manned missions to space pose a great risk on the astronauts. Thus, space exploration risks human life. The stay in a spacecraft is not easy, the conditions are harsh, making the survival during space travel a challenge. Effects of radiation on the body and bone loss resulting from microgravity are some of the health risks during space travel. Of course, unmanned missions eliminate these dangers, but as robots have to be employed, additional technology costs are incurred.
▸ We always associate space research with the discovery of life or precious materials that could be of our use. But exploring space may land us in trouble. In space, we may find something that is lethal to the life on Earth. We may discover something that is harmful to the living beings on our planet. There is a possibility of finding dangerous organisms.
▸ What we leave behind in space, known as space junk or space debris, leads to space pollution. The debris include coolant droplets, dust, non-functional spacecraft, old satellites, and pieces of any man-made objects that continue to orbit the Earth.
▸ Uniting the world may be cited as an advantage of space exploration. However, it may lead to disputes within nations. Satellites could be used by one country to spy over another. Among the cons of space travel is that it may be conducted with the wrong intentions. This may lead to strained relations between countries as also an unhealthy competition.
Space exploration can mean a major leap for mankind. However, it is also criticized for not having achieved any major scientific breakthroughs. Public interest can serve as the determinant in judging the suitability of space exploration. It may not be wise to make such huge expenses on space exploration if other human needs are being ignored or left unfulfilled. But the hope to find extraterrestrial life thrives on space exploration.

Space exploration is beneficial to mankind in many ways. It should not be viewed as a waste of resources, time, or money. There are different arguments concerning the issue whether space exploration is a waste or not.

Space exploration and astronomy in general allow us to learn more about our home, the Earth. We are now aware of the existence of other planets, stars, and galaxies that exist beyond it. As humanity develops, so does the technological exploration that improves our abilities to travel to space, which are beneficial to us despite the fact that many opponents do not agree here.
Counterarguments only consider the disadvantages that come with space exploration – for example, the expensive cost of operations. But we should take into consideration that space exploration comes together with important technological improvements. Heavy reliance on technology triggers extensive research that develops technical knowledge that is applied not only in space exploration. Doeden (2011) asserts that space exploration involves investigation of physical conditions in space and on stars, planets, and their moons using artificial satellites. Astronomy encourages future generations to focus on what is beyond the Earth whether for fun or scientific discoveries. In addition, it creates sufficient awareness about what is around our planet.

Public contention and politics have over the years become a big challenge for space exploration. It is a political problem because of the high level of resources required for the related projects. Some members of the public ask why it is necessary to waste their money on space while it can be spent for some other purposes. This is an indicator of the lack of knowledge about the benefits of space exploration. Not many people remember that owing to astronomy and space exploration, we have learned that there is water on the Moon, meaning that there is a possibility of existence of life. The efforts in this case were applied for the overall benefit of mankind (Morris, 2012). Competition to travel to the Moon was at first a political issue that became competition between countries (Sadeh, 2002).

Space exploration has the potential of discovering new concepts and phenomena about space. These activities resolve mysteries about everything that surrounds the Earth. Through the exploration of space, we may discover resources that will help us in future – for example, minerals and rocks (Kirkland, 2010). This would be a good investment because of the pressure on the existing resources on Earth. And it is not just a fulfillment of the human appetite for adventure; rather, there is a lot to benefit from. Stott says that the “majority of those against space exploration do not understand its benefits to humanity” (Stott, 2010).

Space exploration brings together different people from various research and science fields and puts them to work on some very difficult problems. The result in this case is seen in useful inventions and discoveries. Thus, space exploration triggers technological advancement and is worth its cost because it benefits the people. Without knowledge of our surroundings we become vulnerable to threats. The Sun, asteroids, and other things around us can pose a great threat. Space exploration gives us better understanding of all the possible dangers we face and our relationship with things like the Sun and the Moon. A number of arguments against space exploration show that we do not have enough money to waste on such activities. Underfunding of space exploration programs leads to poor results. Space travel costs millions of dollars for a single trip. It is possible to pay millions to go to space adventure tours. For tours that are more than just adventure, the cost is justified (Morris, 2012).

The satellites in space help us predict any hazardous weather conditions and provide services such as television and communications. Without space exploration, television and communication services would not be as they are. Angelo shows that space programs also lead to other cutting edge technology developments that critics still take for granted – for example, long distance communication and smoke detectors. Cost should not be a concern in such important matters. Space exploration has pros and cons in this case. It is necessary to determine the level of disadvantages as opposed to advantages in terms of expenditures.

The cost of space exploration is high, but the return is even higher, thus making space exploration well worth the cost. Those who are convinced that it is all about wasteful adventure lack knowledge about basic things like telecommunication satellites in space. It is true, we have to settle the matters down here before focusing on those outside…
