Even if you consider only our solar system, there are asteroid and comet threats which could devastate our planet if an impact were to occur. Exploring space gives us an opportunity to locate these hazards in advance to prepare an encounter that could help to preserve our race. Then there are the interstellar items to consider.
It was originally thought to be an asteroid, then a comet since it was accelerating, and up to 10 times as long as it was wide. These items could create interstellar impacts as well.
18 Biggest Advantages and Disadvantages of Space Exploration
It gives us more information about our solar system, galaxy, and universe. When we take on the effort to start exploring space, then we can discover new truths about our planet and culture simultaneously. The information we obtain from these studies can then be applied to our STEM resources here at home. NASA technologies that were originally developed for space programs include infrared ear thermometers, LED lighting, ventricular-assist devices, anti-icing systems, and even temper foam.

Because it requires us to innovate to reach to the stars, our efforts to solve critical problems create opportunities to make life better here on our planet at the same time. Exploring space is one of the few human endeavors that crosses borders. There are currently 72 countries who claim to have a space program, but there are only three which have an operating government space agency: China, Russia, and the United States. Despite the political conflicts that occur between these nations, their capability of producing human spaceflight provides the gold standard for future exploration efforts.
Only 14 of the 72 nations who operate in this space even have a basic launch capacity and six adding Europe, India, and Japan have the capability to launch or recover multiple satellites.

Because of the expenses and resources necessary to achieve space flight, the remaining nations work together with those who have the capability of a full launch to manage this aspect of human existence. This endeavor is one of the few ways that humans from all nations cooperate without conflict. We can see humanity in a different way with space exploration.
Carl Sagan suggested that Voyager 1 take a picture of Earth while it was 4 billion miles away at more than 30 degrees above the ecliptic plane. In that image, our planet appears as a 0. All of our conflicts, political battles, successes, failures, love, loss, and life occur on this one-tenth of a pixel. In the scope of a universal lens, we are but one small point of light amount countless others. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.
The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer, every king and peasant… every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam. Space exploration provides us access to new raw materials. When we began to launch satellites into space, it allowed us to find new raw material deposits on our planet that we could access to make life easier here.
If we apply this technology as an extension to the rest of our solar system, then it gives us the same benefit to find minerals, precious metals, and even new materials that we can use. Although the expense of exploring space is admittedly high, this advantage gives us a way to offset those costs somewhat. There is even the potential that it could become profitable one day if we can provide these efforts with enough capital. Investments into space exploration create real economic benefits at home.
The governments which provide the majority of our space exploration infrastructure employ over 20, people per agency who make direct positive economic impacts on their community. There are private companies who look at the potential benefits of this industry and contribute to this advantage as well, such as SpaceX and their thousands of staff. People from all walks of life contribute to space exploration every day, ranging from astronomers to actual rocket scientists.
These opportunities allows us to explore many different fields of study in addition to what is waiting in the universe as well. Anyone can become a space explorer. If you own a telescope and can look up at the sky, then you can embrace this element of human existence. Our scientists have taken this advantage to the next level with the Hubble Space Telescope, which has made over 1 million observations in almost 30 years of service.
https://johfaiparancho.tk We have made some incredible discoveries with this technology already. Space exploration encourages us to share instead of being selfish. It is a way for us to find common ground outside of our physical appearance, cultural differences, or religious preferences. For far too long, we have allowed ourselves to be consumed by our petty problems instead of looking at the big picture. If someone is hungry, then we should feed them. If they are cold, then we should clothe them. If they need a job, then we should help to train them.

Space exploration unites us in ways that other global efforts do not because we see ourselves as humans first. We know more about our planet thanks to our efforts to explore space. Because space exploration gives us a different perspective, it allows us to look at our planet in a different way.
The view from outside of our atmosphere allows us to see the big picture instead of trying to extrapolate information from micro-scale research. This advantage allowed us to discover the problem of ozone depletion in the upper atmosphere, begin the conversations on global warming, and examine the current and future impact of weather pattern changes that may happen because of a changing climate. Space exploration helps us to look inward as well as outward, helping us all to find the changes that are necessary to keep our planet healthy for our children, grandchildren, and beyond.
Our current technology makes it dangerous to get into space in the first place. We currently strap astronauts into a vehicle that gets attached to a very large rocket so that there is enough speed available to break the grasp of gravity. Starting with Theodore Freeman, who was killed in the crash of a T in October , there have been over 20 individuals who lost their lives in the line of duty while advancing U.
There have been two individuals Gus Grissom and Peter Siebold who were able to survive a problem that resulted in the loss of a space vehicle. There are cost considerations to look at with space exploration. The cost of exploring space is one of the biggest criticisms of the efforts to launch a program that takes us beyond our planet. That figure does not include the expenses of postponement that often occurred because the conditions were not right to send a rocket into space.
Technology advancements in recent years could make this issue cheaper for the next generation, but we should ask ourselves if spending billions on space exploration is the right thing to do if we have people dying of hunger on our planet. Astronauts receive exposure to natural dangers while in space. The radiation that comes from the sun is a constant danger to astronauts when they are in space, and the weightless environment can change their physical conditioning.
Experiments with identical twins, with one staying on our planet and the other spending a lengthy assignment in space, show that there are changes at the cellular and genetic level that occur with space travel as well.

Sure, it's great that NASA can elevate technology to the next level time and time again, so why not make technology that directly benefits us? And as there are millions round the world who are starving to death, when people spend more and more money on space technology they should realize they are the killers. Also, why take so much time and money to learn about Mars or any other planet, when we know so little about our own? We should learn more about Earth and the ocean before wasting time and money on Space exploration. No because Production of these product leads to redevelopment, sales and distribution - all of which leads to more jobs; somebody has to build, sell, and repair.
One last point, we know that Russia and China have both put men in space and now even more countries are getting involved. Obviously we have seen the power of Google Maps and that is only at the civilian level. Imagine now, that other powerful countries have satellites to spy on us and can position weapons directly above our country, dont you think it would be a good idea to be abloe to stave that off.
If we decided to stop "wasting" money on space programs, we can say goodbye to many new developments that will be out of reach of garage scientist and we can expect to be overwhelmed with visitors in the skies above the US. There are endless possibilities, ranging from solar energy farms to revolutionary and cheap intercontinental transportation. Imagine a solar farm, capable of harvesting the solar winds; this translates to an unlimited supply of energy for not just the United States, but the entire world! The human race is changing, and expanding.
Soon, the Earth will simply not be big enough and we need to start considering our future as a species. There are issues that do plague us as a race. There is poverty and injustice in the world. While these issues exist and should certainly not be ignored, the funds put forth to space exploration have a quantifiable impact and are no less of a priority.
These problems will likely not be solved by the evolution of invention and space exploration alone, but as technology improves so will the lives of every man, woman, and child regardless of gender, skin color, or wealth. Space exploration needs focus and funding, it is representative of our future, and will secure it. Space exploration is arguably the single-most important investment we could possibly make. Space exploration gives us no direct benefit There have been no direct benefits from space travel; the only 'good things' to come from it are indirect, and not the end aims.
NASA weren't aiming for velcro, but the moon. We got velcro, the moon gave us nothing except some pretty pictures of the planet below. Scientists and inventors could give us the same by-products for a lot less cost if the associated space exploration was removed from the equation. All the by-products of the space race could have been developed by commercial companies aiming to make a profit by developing good products and selling them, at a fraction of the cost: the Post-it note is possibly as useful as velcro, but was developed by 3M at a fraction of the cost.
Furthermore, a lot of the 'advances' space exploration bring us is irrelevant to daily life: why bother spending money developing a pen that works in zero-gravity when a a pencil will do and b the vast majority of the world's 6 billion people will never experience zero gravity? However indirect they might be, the advances would not have come were it not for the space programmes of NASA, as there would have been no technological need. Space exploration gave impetus to projects that have been useful, as well as providing valuable scientific knowledge.
For example, the laser-targetting of mirrors left on the moon by Apollo astronauts helps test and understand basic physics, which in turn leads to advances in very earthly things like electronics, hyper-conductivity, etc. Anyway, space exploration absolutely does give us a direct benefit. When space technology has advanced far enough, we will be able to leave this planet in large numbers and live among the stars.
