Why space exploration is always worthwhile

Your guide to advocating for space in a complicated world.

Most people who love space and believe in exploration have probably heard this once or twice: “We shouldn’t waste money on space exploration when there are problems to deal with here on Earth.”

While public health concerns, social injustices, climate change, and other urgent issues are important to address, solving these problems doesn’t depend on defunding space programs.

This can be a difficult conversation to navigate, so we’ve outlined a few ideas here that you can share when advocating for space.

Space research isn’t as expensive as people think

Many countries around the world invest in space science and exploration as a balanced part of their total federal budget. Public opinion research has shown that people estimate NASA to take up as much as a quarter of the U.S. federal budget, but in fact,  NASA’s budget only represents about 0.5% of the total federal budget and the proportion is even smaller for other spacefaring nations . The correct information may go a long way to reassuring critics that space spending isn’t eating up as many public resources as they think.

The United States government spent approximately $6.6 trillion in fiscal year 2020, of which just 0.3% ($22.6 billion) was provided to NASA. In this chart, shades of blue represent mandatory spending programs; shades of orange are discretionary programs that require annual appropriations by Congress. "Defense and related" includes both the Department of Defense and Veterans Affairs. Source: Office of Management and Budget Historical Tables 8.5 and 8.7.

Space spending pays off

If someone is arguing that public funds should be spent on solving the world’s problems, they should know that money spent on NASA positively impacts the U.S. economy . We get the same kind of payoff for space spending in other countries. Spending on space supports highly skilled jobs, fuels technology advancements with practical applications, and creates business opportunities that feed back into the economy. This in turn grows the pool of public money that can be spent on solving the world’s most pressing problems.

Space research directly impacts Earthly problems

When people apply themselves to the challenges of exploring space, they make discoveries that can help the world in other ways too. Studying how we might grow food in orbit or on Mars yields insights into growing food in extreme conditions on Earth , generating knowledge that can help mitigate the impacts of climate change. Medical research conducted on the International Space Station helps us understand the human body in new ways, helping save lives and improve quality of life .

Studying space helps us understand our own world

Studying the cosmos gives us an important perspective shift. When we learn about what lies beyond Earth, it gives us context for understanding our own planet. Studying the other worlds of our solar system and beyond makes it clear that Earth is a precious oasis for life. When we sent spacecraft to Venus we saw how a runaway greenhouse effect turned the world from a habitable planet to an absolute hellscape. When astronauts travel into space they see just how thin and tenuous Earth’s atmosphere is, appreciating the fragile balance in which we live . A cosmic perspective underscores the importance of protecting our planet’s habitability and encourages investment in that effort.

Studying space may one day save us all

All the social and environmental progress in the world won't help us if an asteroid impacts the Earth. We have to explore space to find and study the asteroids and comets in our cosmic neighborhood if we want to make sure we can  defend our planet  if an object ever heads our way.

Space is inspiring

Not every child who dreams of becoming an astronaut will get that opportunity. This is a sad truth that many of us know from experience. But to be inspired to aim for something so grand gives kids the motivation to study hard and gain skills in science, engineering, medicine, or other fields that benefit humanity and directly help overcome problems that we face as a species.

And inspiration isn’t just for kids. When we marvel at the beauty of Jupiter’s clouds or the mystery of Enceladus’ oceans , we get an opportunity to appreciate the wonder and majesty of this cosmos that we inhabit. The idea that life might exist elsewhere in the universe reminds us that we might not be the only planet struggling to achieve balance, justice, and sustainability. And even in the bleakest of times, there’s something beautiful about still striving to achieve something great and discover something that could change how we see ourselves and our cosmos forever.

There’s plenty of room at the table

There’s no denying that there are many important issues facing humanity that need fixing. But to deal with those problems doesn’t mean we have to stop looking up, stop exploring, and stop making discoveries.

Human civilization has astonishing capacity, and we can do more than one important thing at a time. If someone thinks that a particular issue should get more attention and investment, they can and should advocate for that. The problems we face don’t persist because we’re spending money on space science and exploration. And there’s no reason to pit our aspirations against one another.

The Time is Now.

Essay on Space Exploration

• Updated on  
• Jun 11, 2022

For scientists, space is first and foremost a magnificent “playground” — an inexhaustible source of knowledge and learning that is assisting in the solution of some of the most fundamental existential issues concerning Earth’s origins and our place in the Universe. Curiosity has contributed significantly to the evolution of the human species. Curiosity along with the desire for a brighter future has driven humans to explore and develop from the discovery of fire by ancient ancestors to present space explorations.  Here is all the information you need and the best tips to write an essay on space exploration.

What is Space Exploration?  

Space Exploration is the use of astronomy and space technology to explore outer space. While astronomers use telescopes to explore space, both uncrewed robotic space missions and human spaceflight are used to explore it physically. One of the primary sources for space science is space exploration, which is similar to astronomy in its classical form. We can use space exploration to validate or disprove scientific theories that have been created on Earth. Insights into gravity, the magnetosphere, the atmosphere, fluid dynamics, and the geological evolution of other planets have all come from studying the solar system.

Advantages of Space Exploration 

It is vital to understand and point out the advantages of space exploration while writing an essay on the topic.

New inventions have helped the worldwide society. NASA’s additional research was beneficial to society in a variety of ways. Transportation, medical, computer management, agriculture technology, and consumer products all profit from the discoveries. GPS technology, breast cancer treatment, lightweight breathing systems, Teflon fibreglass, and other areas benefited from the space programme.

It is impossible to dispute that space exploration creates a large number of employment opportunities around the world. A better way to approach space exploration is to spend less and make it more cost-effective. In the current job market, space research initiatives provide far too much to science, technology, and communication. As a result, a large number of jobs are created.

Understanding

NASA’s time-travelling space exploration programmes and satellite missions aid in the discovery of previously unknown facts about our universe. Scientists have gained a greater understanding of Earth’s nature and atmosphere, as well as those of other space entities. These are the research initiatives that alert us to impending natural disasters and other related forecasts. It also paves the way for our all-powerful universe to be saved from time to time.

Disadvantages of Space Exploration

Highlighting disadvantages will give another depth to your essay on space exploration. Here are some important points to keep in mind.

Pollution is one of the most concerning issues in space travel. Many satellites are launched into space each year, but not all of them return. The remnants of such incidents degrade over time, becoming debris that floats in the air. Old satellites, various types of equipment, launch pads, and rocket fragments all contribute to pollution. Space debris pollutes the atmosphere in a variety of ways. Not only is space exploration harmful to the environment, but it is also harmful to space.

A government space exploration programme is expensive. Many people believe that space mission initiatives are economical. It should be mentioned that NASA just celebrated its 30th anniversary with $196.5 billion spent.

Space exploration isn’t a walk in the park. Many historical occurrences demonstrate the dangers that come with sad situations. The Challenger space shuttle accident on January 28, 1986, must be remembered. The spacecraft exploded in under 73 seconds, resulting in a tremendous loss of life and property.

Conclusion 

There are two sides to every coin. To survive on Earth, one must confront and overcome obstacles. Space exploration is an essential activity that cannot be overlooked, but it can be enhanced by technological advancements.

Space Exploration Courses

Well, if your dream is to explore space and you want to make a career in it, then maybe space exploration courses are the right choice for you to turn your dreams into reality.

Various universities offering space exploration courses are :

• Arizona State University, USA
• Bachelor of Science in Earth and Space Exploration

Tips to write an IELTS Essay  on Space Exploration

• The essay’s word count should be at least 250 words. There is no maximum word count. If you write less than 250 words, you risk submitting an incomplete essay. The goal should be to write a minimum of 250-words essay.
• There will be more than one question on the essay topic. The questions must be answered in their entirety. For example, for the topic ‘crime is unavoidable,’ you might see questions like 1. Speak in favour of and against this topic, 2. Give your opinion, and 3. Suggest some measures to avoid crime. This topic now has three parts, and all of them must be answered; only then will the essay be complete.
• Maintain a smooth writing flow. You can’t get off track and create an essay that has nothing to do with the issue. The essay must be completely consistent with the question. The essay’s thoughts should be tied to the question directly. Make use of instances, experiences, and concepts that you can relate to.
• Use a restricted number of linking phrases and words to organise your writing. Adverbial phrases should be used instead of standard linking words.
• The essay should be broken up into little paragraphs of at least two sentences each. Your essay should be divided into three sections: introduction, body, and conclusion. ( cheapest pharmacy to fill prescriptions without insurance )
• Don’t overuse complicated and long words in your essay. Make appropriate use of collocations and idioms. You must be able to use words and circumstances effectively.
• The essay must be written correctly in terms of grammar. In terms of spelling, grammar, and tenses, there should be no mistakes. Avoid using long, difficult sentences to avoid grammatical problems. Make your sentences succinct and to-the-point.

10 Reasons Why Space Exploration Matters to You

At the time of the moon landing in 1969, many people envisioned that by the beginning of the 21st century, space travel would become routine, and we would be visiting other planets in our solar system and perhaps even daring to venture into interstellar space.

That future didn't arrive as planned. In fact, humans haven't made it any deeper into space than when we landed the moon in the late 1960s and early 1970s, though we have operated a manned orbital outpost, the International Space Station, which has been continuously occupied for more than two decades [source: Howell ]. NASA currently is planning to resume human missions to the moon in the mid-to-late 2020s, as a prelude to astronauts eventually traveling to Mars [source: Dvorsky ].

We've also seen the rise of private space entrepreneurs such as Elon Musk, who has described his dream of building a rocket capable of reaching Mars and supporting a permanent human settlement there [source: Torchinsky ]. And other countries are looking to reach Mars as well. China, for example, aims to send its astronauts to the Red Planet by 2033 [source: Kharpal ].

But those who've long dreamed of humans becoming a truly spacefaring race argue that exploring space provides down-to-earth benefits in areas such as health, mining and security. And more inspirational benefits, too. Here are some of the most compelling arguments for continuing the exploration of space.

• Protection From a Catastrophic Asteroid
• It Will Lead to More Great Inventions
• It Will Be Good for Your Health
• Space Exploration Is Inspirational
• It's Important for National Security
• We Need Raw Materials From Space
• Nations Can Work Together Peacefully
• It Could Help Answer a Really Big Question
• Humans Need to Fulfill Their Urge to Explore
• We May Need to Colonize Space to Survive

10: Protection From a Catastrophic Asteroid

If we don't want to go the way of the dinosaurs someday, we need to protect ourselves against the threat of being hit by a big asteroid. According to NASA , typically about once every 10,000 years, a rocky or iron asteroid the size of a football field could smash into our planet's surface and possibly cause tidal waves big enough to inundate coastal areas.

But it's the real monsters — asteroids about 328 feet (100 meters) across or bigger — that we really have to fear. Such a collision would unleash a firestorm of heated debris and fill the atmosphere with sun-blocking dust, which would wipe out forests and farm fields and starve the human and animal life that it didn't immediately kill [sources: NASA , NSS ].

That's why it's vital to develop a way to neutralize such a threat to Earth. NASA's Double Asteroid Redirection Test , set for launch in late September 2022, will be the first mission to demonstrate a technology called asteroid deflection by kinetic impactor. A robotic spacecraft will be crashed into the binary asteroid system Didymos, in an effort to show that it's possible to slightly alter the path of an asteroid. That would enable NASA to redirect potential threats to miss Earth [sources: DART , Mann ].

9: It Will Lead to More Great Inventions

A very long list of gadgets, materials and processes originally were developed for the U.S. space program but found other applications back on Earth — so many that NASA has an office that looks for ways to repurpose space technology as products. We all know about freeze-dried food, but there are plenty of others. In the 1960s, for example, NASA scientists developed a plastic coated with a metallic reflecting agent. When used in a blanket, it reflects about 80 percent of a user's body heat back to him or her — an ability that helps accident victims and post-marathon runners to stay warm.

Another more obscure but valuable innovation is nitinol , a flexible but resilient alloy that was developed to enable satellites to spring open after being folded into a rocket. Today, orthodontists equip patients with braces made from the material [source: Independent ].

According to NASA, other inventions spawned by the space program include CAT scans, LED lights, memory foam, freeze-dried food, shock absorbing materials used in artificial limbs, the computer mouse and portable computers, and a key nutritional ingredient in baby formula [source: JPL ].

8: It Will Be Good for Your Health

The International Space Station alone has generated scores of medical innovations with uses on Earth, such as a method for delivering cancer-fighting medication directly to tumors; gadgetry that a nurse can hold to perform ultrasounds and transmit the results to a doctor thousands of miles away; and a robotic arm that can perform delicate surgery inside an MRI machine.

NASA scientists, in an effort to protect astronauts from losing bone and muscle in the microgravity environment of space, also helped a pharmaceutical company to test Prolia, a drug that today helps protect elderly people from osteoporosis. Although mice and humans don't have identical physiology or biology, it made sense to test this drug on mice in space, since astronauts lose around 1.5 percent of their bone mineral density each month in microgravity, which correlates to the 1.5 percent yearly bone density loss of an elderly woman on Earth to osteoporosis [source: Kiger ].

7: Space Exploration Is Inspirational

If we want a world in which our kids aspire to being great scientists and engineers instead of reality show hosts, rappers or Wall Street financial tycoons, having a great enterprise to attract and inspire them is crucial.

As astrophysicist, author and lecturer Neil deGrasse Tyson told National Public Radio in 2012, "I could stand in front of eighth graders and say, 'Who wants to be an aerospace engineer so you can design an airplane 20 percent more fuel-efficient than the one your parents flew?' That doesn't usually work. But if I say, 'Who wants to be an aerospace engineer to design the airplane that will navigate the rarefied atmosphere of Mars?' ... I'm getting the best students in the class." This still holds true today and inspiring kids will always be the key to future space exploration.

6: It's Important for National Security

The U.S. needs to detect and prevent a hostile nation or terrorist group from deploying space-based weapons or attacking its navigational, communications and surveillance satellites. And while it and other major powers such as Russia and China are signatories of a 1967 treaty that forbids nations from claiming territory in space, it's not hard to think of examples of past treaties that were tossed aside when someone saw a benefit in doing so.

Even if the U.S. privatizes much of space exploration, it still wants to ensure that companies can mine the moon or asteroids without worrying that interlopers will usurp their claims or steal their production [source Minter ]. That's why it's crucial to back up diplomacy with a NASA spacefaring capacity that could be converted to military use, if needed. In 2019, a law passed by Congress with bipartisan support created the U.S. Space Force, a new branch of the U.S. armed forces devoted to protecting U.S. interests in space [source: Space Force ].

5: We Need Raw Materials From Space

There's gold out there in the cosmos, and silver , platinum and other valuable substances, too [source: Letzter ]. A lot of attention has been given to a private-sector venture that envisions mining operations on asteroids, but space miners wouldn't have to go that far to find riches.

The moon, for example, is a potentially lucrative source of helium-3 , which is used for certain MRIs and a possible fuel for nuclear power plants. The moon also is believed to be a potential source of rare earth elements such as europium and tantalum, which are in high demand for use in electronics, solar panels and other advanced gadgetry [source: Ouellette ].

4: Nations Can Work Together Peacefully

Earlier, we mentioned the ominous notion of international conflict in space. But it doesn't have to be that way, as evidenced by the cooperation of multiple nations on the International Space Station . And a U.S. space program could allow other countries, large and small, to join in their exploration efforts.

A 2018 paper from NASA points out the benefits of international cooperation . For one, the hefty costs could be spread around. For another, it could forge stronger diplomatic ties between nations such as the U.S. and India, and help create new jobs in both countries, for example.

In 2020, NASA awarded the first contracts to four companies to collect small amounts of lunar regolith, the loose rock and dust that sits atop the surface, when missions to the moon eventually resume in the 2020s. It could be the first step toward mining of raw materials from the moon. "Space resources are the fuel that will propel America and all of humanity to the stars," Mike Gold, NASA's then-acting administrator for international and interagency relations, explained at the time [source: NASA ].

3: It Could Help Answer a Really Big Question

Nearly two-thirds of Americans (close to 65 percent) believe that intelligent life exists on other planets, according to a 2021 Pew Research Center survey. In general, the public does not view UFOs as a major threat to the country. When asked to think about U.S. national security, 51 percent of Americans say that UFOs are not a threat at all, and 36 percent believe they are a minor threat.

But so far, sweeps of the sky with Earth-based telescopes for signals that might be beacons from distant civilizations have proven fruitless, possibly because the Earth's atmosphere interferes with such messages reaching us. That's why searchers for extraterrestrial civilizations are eager for the deployment of more orbital observatories such as the James Webb Space Telescope. That satellite, which was launched on Christmas Day 2021, has the ability to search for the chemical signs of life in the atmospheres of distant planets outside our solar system [sources: Kramer , Howell ]. That's a start, but an even more aggressive space-based effort to look for clues of extraterrestrials might finally help us to answer the question of whether we have company out there.

2: Humans Need to Fulfill Their Urge to Explore

Our primitive ancestors spread from east Africa to all over the planet, and since then, we've never stopped moving. We're running out of fresh territory on Earth , so the only way to meet this ancient urge is to find somewhere new to go — whether it's making brief jaunts to the moon as a tourist, or signing up for an interstellar voyage that will take multiple generations.

In a speech , to the Bay Area Houston Economic Partnership, former NASA administrator Michael Griffin differentiated between "acceptable reasons" and "real reasons" for space exploration. Acceptable reasons would be issues like economic benefit and national security. But real reasons include concepts like curiosity, competitiveness and monument-building.

"Who among us does not know the wonder and mystery and awe and magic of seeing something, even on television, never seen before, an experience brought back to us by a robotic space mission?" Griffin added that "when we do things for real reasons as opposed to acceptable reasons, we produce our highest achievements."

1: We May Need to Colonize Space to Survive

Already, our ability to put satellites in space is helping us to monitor and combat pressing problems on Earth, from forest fires and oil spills to the depletion of aquifers that people depend upon for drinking water [source: Fowler ].

But our burgeoning population, rampant greed and thoughtlessness about environmental consequences have already done pretty severe damage to our planet. According to a 2012 survey of research, most scientists estimate that Earth has a carrying capacity of between 8 and 16 billion — and we already have a population of nearly 8 billion [source: UNEP ]. That's led some futurists to argue that we should be preparing to colonize another planet, and soon. Your life — or those of your descendants — might depend upon it.

Why Space Exploration Matters FAQs

Why is space exploration important, what are the cons of space exploration, how has space exploration benefited health and medicine, how is space exploration important for national security, what resources can we get from space, lots more information, author's note: 10 reasons why space exploration matters to you.

I was a child in the 1960s, a time when many of us believed that someday we would be flying off into the cosmos in search of adventure. I can't say precisely when that dream ended for me, but I remember that back in the mid-1990s, the British folk singer Billy Bragg recorded a song that seemed to capture some of what I felt. In "The Space Race is Over," Bragg sang of staring at the moon as a child, and dreaming that night of walking on the Sea of Tranquility.

But decades later, he stood staring at the same sky with his young son, who asked him, "Why did they ever go?" As Bragg lamented, "The space race is over, and I can't help but feel that we're all just going nowhere." Despite the beauty of his lyrics, I must differ with him respectfully on that last point. I continue to believe that humanity still has a chance to become a truly spacefaring race, and that we must find a way to do so.

Why explore space?

Why should we explore space? Why should money, time and effort be spent researching something with apparently so few benefits? Why should resources be spent on space rather than on conditions and people on Earth?

Perhaps the best answer lies in our history. What made our ancestors move from the trees onto the plains? Did a wider distribution of our species offer a better chance of survival?

Nearly all successful civilisations have been willing to explore. In exploring, the dangers of surrounding areas may be identified and prepared for. Without knowledge, these dangers have the ability to harm us. With knowledge, their effects or consequences may be lessened.

While many resources are spent on what seems a small return, the exploration of space allows new resources to be created. Resources translate into success at survival. Resources may be more than physical assets.

Knowledge or techniques acquired in exploring or preparing to explore always filter from the developers to the general population.

Techniques may be medical applications, such as new drugs or ways of living to increase the quantity or the quality of time lived. Techniques may be social, allowing the people in a society to better understand those within or outside that culture.

ESA’s space programme is a strategic asset. ESA does what individual European nations cannot do on their own.

Scientists from European nations can function at world-class level in their specialist fields, in co-operation rather than competition.

By studying alien worlds, such as Venus, Mars or Saturn’s moon Titan, we can place our own world in context. ESA’s exploration of the Solar System is focused on understanding the Earth’s relationship with the other planets, essential stepping stones for exploring the wider Universe.

While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The chance of a large asteroid or comet hitting the Earth is small. But given time, it will happen.

Some explanations for extinctions and evolution include strikes by asteroids or comets. Our technology is reaching the point where we can detect such a threat and might be able to do something about it.

The dangers exist and knowledge can allow us as a species to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

Earth is the only planet known to sustain life, but our ability to adapt could eventually allow us to inhabit other planets and moons.

Our lifestyles would be different, but human life and cultures have adapted in the past and surely could in the future. Space allows us to expand and succeed.

space exploration , investigation, by means of crewed and uncrewed spacecraft , of the reaches of the universe beyond Earth ’s atmosphere and the use of the information so gained to increase knowledge of the cosmos and benefit humanity. A complete list of all crewed spaceflights, with details on each mission’s accomplishments and crew, is available in the section Chronology of crewed spaceflights .

Humans have always looked at the heavens and wondered about the nature of the objects seen in the night sky. With the development of rockets and the advances in electronics and other technologies in the 20th century, it became possible to send machines and animals and then people above Earth’s atmosphere into outer space . Well before technology made these achievements possible, however, space exploration had already captured the minds of many people, not only aircraft pilots and scientists but also writers and artists. The strong hold that space travel has always had on the imagination may well explain why professional astronauts and laypeople alike consent at their great peril, in the words of Tom Wolfe in The Right Stuff (1979), to sit “on top of an enormous Roman candle, such as a Redstone, Atlas , Titan or Saturn rocket , and wait for someone to light the fuse.” It perhaps also explains why space exploration has been a common and enduring theme in literature and art. As centuries of speculative fiction in books and more recently in films make clear, “one small step for [a] man, one giant leap for mankind” was taken by the human spirit many times and in many ways before Neil Armstrong stamped humankind’s first footprint on the Moon .

Achieving spaceflight enabled humans to begin to explore the solar system and the rest of the universe, to understand the many objects and phenomena that are better observed from a space perspective, and to use for human benefit the resources and attributes of the space environment . All of these activities—discovery, scientific understanding, and the application of that understanding to serve human purposes—are elements of space exploration . (For a general discussion of spacecraft , launch considerations, flight trajectories, and navigation , docking, and recovery procedures, see spaceflight .)

Overview of recent space achievements

Although the possibility of exploring space has long excited people in many walks of life, for most of the latter 20th century and into the early 21st century, only national governments could afford the very high costs of launching people and machines into space. This reality meant that space exploration had to serve very broad interests, and it indeed has done so in a variety of ways. Government space programs have increased knowledge, served as indicators of national prestige and power, enhanced national security and military strength, and provided significant benefits to the general public. In areas where the private sector could profit from activities in space, most notably the use of satellites as telecommunication relays, commercial space activity has flourished without government funding. In the early 21st century, entrepreneurs believed that there were several other areas of commercial potential in space, most notably privately funded space travel.

In the years after World War II , governments assumed a leading role in the support of research that increased fundamental knowledge about nature, a role that earlier had been played by universities, private foundations, and other nongovernmental supporters. This change came for two reasons. First, the need for complex equipment to carry out many scientific experiments and for the large teams of researchers to use that equipment led to costs that only governments could afford. Second, governments were willing to take on this responsibility because of the belief that fundamental research would produce new knowledge essential to the health, the security, and the quality of life of their citizens. Thus, when scientists sought government support for early space experiments, it was forthcoming. Since the start of space efforts in the United States , the Soviet Union , and Europe , national governments have given high priority to the support of science done in and from space. From modest beginnings, space science has expanded under government support to include multibillion-dollar exploratory missions in the solar system. Examples of such efforts include the development of the Curiosity Mars rover, the Cassini-Huygens mission to Saturn and its moons, and the development of major space-based astronomical observatories such as the Hubble Space Telescope .

Soviet leader Nikita Khrushchev in 1957 used the fact that his country had been first to launch a satellite as evidence of the technological power of the Soviet Union and of the superiority of communism . He repeated these claims after Yuri Gagarin ’s orbital flight in 1961. Although U.S. Pres. Dwight D. Eisenhower had decided not to compete for prestige with the Soviet Union in a space race, his successor, John F. Kennedy , had a different view. On April 20, 1961, in the aftermath of the Gagarin flight, he asked his advisers to identify a “space program which promises dramatic results in which we could win.” The response came in a May 8, 1961, memorandum recommending that the United States commit to sending people to the Moon , because “dramatic achievements in space…symbolize the technological power and organizing capacity of a nation” and because the ensuing prestige would be “part of the battle along the fluid front of the cold war.” From 1961 until the collapse of the Soviet Union in 1991, competition between the United States and the Soviet Union was a major influence on the pace and content of their space programs. Other countries also viewed having a successful space program as an important indicator of national strength.

Even before the first satellite was launched, U.S. leaders recognized that the ability to observe military activities around the world from space would be an asset to national security. Following on the success of its photoreconnaissance satellites, which began operation in 1960, the United States built increasingly complex observation and electronic-intercept intelligence satellites. The Soviet Union also quickly developed an array of intelligence satellites, and later a few other countries instituted their own satellite observation programs. Intelligence-gathering satellites have been used to verify arms-control agreements, provide warnings of military threats, and identify targets during military operations, among other uses.

In addition to providing security benefits, satellites offered military forces the potential for improved communications, weather observation, navigation, timing, and position location. This led to significant government funding for military space programs in the United States and the Soviet Union. Although the advantages and disadvantages of stationing force-delivery weapons in space have been debated, as of the early 21st century, such weapons had not been deployed , nor had space-based antisatellite systems—that is, systems that can attack or interfere with orbiting satellites. The stationing of weapons of mass destruction in orbit or on celestial bodies is prohibited by international law .

Governments realized early on that the ability to observe Earth from space could provide significant benefits to the general public apart from security and military uses. The first application to be pursued was the development of satellites for assisting in weather forecasting . A second application involved remote observation of land and sea surfaces to gather imagery and other data of value in crop forecasting, resource management, environmental monitoring, and other applications. The U.S., the Soviet Union, Europe, and China also developed their own satellite-based global positioning systems , originally for military purposes, that could pinpoint a user’s exact location, help in navigating from one point to another, and provide very precise time signals. These satellites quickly found numerous civilian uses in such areas as personal navigation, surveying and cartography, geology, air-traffic control , and the operation of information-transfer networks. They illustrate a reality that has remained constant for a half century—as space capabilities are developed, they often can be used for both military and civilian purposes.

Another space application that began under government sponsorship but quickly moved into the private sector is the relay of voice, video, and data via orbiting satellites. Satellite telecommunications has developed into a multibillion-dollar business and is the one clearly successful area of commercial space activity. A related, but economically much smaller, commercial space business is the provision of launches for private and government satellites. In 2004 a privately financed venture sent a piloted spacecraft, SpaceShipOne , to the lower edge of space for three brief suborbital flights. Although it was technically a much less challenging achievement than carrying humans into orbit, its success was seen as an important step toward opening up space to commercial travel and eventually to tourism . More than 15 years after SpaceShipOne reached space, several firms began to carry out such suborbital flights. Companies have arisen that also use satellite imagery to provide data for business about economic trends . Suggestions have been made that in the future other areas of space activity, including using resources found on the Moon and near-Earth asteroids and the capture of solar energy to provide electric power on Earth , could become successful businesses.

Most space activities have been pursued because they serve some utilitarian purpose, whether increasing knowledge, adding to national power, or making a profit . Nevertheless, there remains a powerful underlying sense that it is important for humans to explore space for its own sake, “to see what is there.” Although the only voyages that humans have made away from the near vicinity of Earth—the Apollo flights to the Moon—were motivated by Cold War competition, there have been recurrent calls for humans to return to the Moon, travel to Mars, and visit other locations in the solar system and beyond. Until humans resume such journeys of exploration, robotic spacecraft will continue to serve in their stead to explore the solar system and probe the mysteries of the universe.

How can astronomy improve life on earth?

Much of astronomy is concerned with understanding distant phenomena, seeing the invisible, and studying the most extreme events in the Universe. But how does this pursuit help our daily lives here on Earth?

The need for extremely precise instrumentation in astronomy can often be transferred into the medical field. Beyond pure research, which benefits humanity through various technological applications, some laboratories at the Center for Astrophysics pursue research that’s more directly beneficial. 

High-energy and neutron optics laboratories design mirrors for the next generation of space-based telescopes. But with a simple modification, these optics can accurately aim high-energy particles for radiation treatment, focusing on destroying tumors while leaving surrounding tissue unharmed. Engineers are working on mirrors that can both focus neutrons from across the Universe, as well as those from a radioactive source sitting in the same room.

Work on nuclear magnetic resonance, which can be used to study molecular physics, can also be used to scan the human body. When used for imaging, this is known as magnetic resonance imaging, or MRI. Scientists at the CfA are developing an open-access, low-magnetic-field human MRI instrument, that can be used for molecular imaging and the study of traumatic brain injury.

On the other side of the coin, astrophysics sometimes adapts technology from the medical field. The complicated debris leftover after a supernova explosion, known as a supernova remnant, can be hard to visualize. We only have our vantage point and cannot travel around the remnant to view the intricacies of its structure. But by measuring how fast the material is traveling, and whether it’s traveling towards us or away, we can create a 3D map of the material’s motion. Supernova researchers are putting this data into medical imaging software originally designed for brain scans to get a 3D model that can be viewed in 360 degrees. To take it one step further, the models can then be 3D printed, allowing you to hold a dead star in your hand.

The Center for Astrophysics | Harvard & Smithsonian sets the standard for astronomical discovery. By pursuing scientific research, our scientists never know what might be the next big breakthrough. New detector technology means better lighter cameras. Astronomical data analysis software can be reconfigured to make cars safer. Novel techniques in radio astronomy paved the way for wireless internet. We don’t know what we are going to find, but we will never know if we don’t look. 

How Curiosity Drives Ingenuity

Understanding our Universe is not an easy task. It requires an incredible amount of focused effort among worldwide collaborations of dedicated experts, the constant development of new technology at great expense, and theoretical modelling that pushes the boundaries of science. Even without any guarantee of success, such an undertaking has its benefits.

Astronomy is continually innovating and progressing. Seemingly by accident, scientific and technological developments in astronomy have worked their way into our daily lives. For example, the device you’re currently reading this text on is very likely to involve components and systems that saw their first application in astronomy.

Computers, satellites and the smartphones they service, Global Positioning System (GPS), energy-efficient solar panels, digital camera sensors, airport security scanners, portable X-ray machines, and Magnetic Resonance Imaging (MRI) scanners are just a few of technological advances that are the legacy of astronomy, and that benefit us all on Earth. None of these would have happened if we hadn’t first been dedicated to simple human curiosity about what may be out in the far reaches of our Universe. As it has been throughout our history, the impulse to explore is still one of the greatest wellsprings of human ingenuity.

Protecting the Planet

In 1859, the Sun launched an enormous magnetized mass of plasma at the Earth, shorting electrical lines, starting electrical fires and knocking out telegraph communication. The northern lights could be seen as far south as Mexico. If such a solar event hit the Earth today, it is estimated to cause damage measured in the trillions of dollars. 

Coronal mass ejections (CMEs), like the 1859 event, are giant eruptions of charged particles that threaten satellites, astronauts, and our electrical grid. A suite of CFA missions and instruments are monitoring the Sun, giving us warning of incoming CMEs, allowing time to prepare and protect people and our highly susceptible electronic and communication systems.

The X-ray Telescope (XRT) aboard the Hinode spacecraft observes flares, CMEs, and the source of the highly charged flow of particles from the Sun, known as the solar wind.

The Atmospheric Imaging Assembly (AIA), developed by scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA), aboard the Solar Dynamics Observatory (SDO) takes fast, multi-wavelength images of the full sun. This allows scientists to watch monitor features at different temperatures and levels of the solar atmosphere.

The Parker Solar Probe, will race through the Sun’s atmosphere, collecting material and measuring the solar wind at its source. It will eventually orbit seven times closer than any previous satellite, and withstand temperatures of 2,500 degrees (1,377 degrees Celsius). The Solar Wind Electrons Alphas and Protons (SWEAP) Investigation, developed by CfA scientists and engineers, is the set of instruments on the spacecraft that will directly measure the properties of the plasma in the solar atmosphere during these encounters. A special component of SWEAP is a small instrument that will look around the protective heat shield of the spacecraft directly at the Sun. This will allow SWEAP to sweep up a sample of the atmosphere and touch the Sun, our star, for the first time.

Our Sun makes life on Earth possible, but is still an unpredictable, sometimes volatile star. By learning more about our Sun, astronomers can warn us about incoming solar storms and predict the next big eruption.

This image from NASA's Solar Dynamics Observatory shows a large sunspot that produced a coronal mass ejection in 2017. Astronomers monitor solar weather to help predict when such storms might hit Earth, affecting communications and power grids.

Space Watch

Though the Solar System has certainly cleaned up its act in the 66 million years since an asteroid wiped out the dinosaurs, there have since been a couple of near misses that are too close for comfort.

The Minor Planet Center, located at the Center for Astrophysics, is tasked by the International Astronomical Union to collect and circulate positional measurements of minor planets like asteroids and comets. The Center calculates the motions of newfound objects and alerts observers when an object that might impact the Earth is detected. The orbit calculation and announcement of newly discovered Near-Earth Asteroids (NEOs) is a critically important job, ensuring that we won’t suffer the same fate as the dinosaurs.

This diagram shows some of the orbits of known Near Earth Objects (NEOs), asteroids and other bodies that pass close to our planet. Tracking such objects helps us understand how likely they are to strike Earth; thankfully, no known NEO is currently a danger to us.

Benefits Beyond the Balance Sheet

Astronomy has a unique ability to unite humans. Simply by asking big questions about the Universe and our place in it, we see ourselves as we are: together, voyaging through a singular moment in time on one very special but relatively minuscule planet among the vastness of space.

The sense of wonder inspired by humanity’s quest for knowledge of our Universe has its own important applications. In education, we see the teaching of astronomy at the primary or secondary level leading students to pursue careers in STEM (science, technology, engineering, and math). In international relations, we see astronomy as a scientific field that transcends borders and promotes collaboration between global teams in unified pursuit of knowledge. In our culture, we see the impact of keystone scientific discoveries creating a more informed and scientifically literate society.   And let’s not forget that astronomy offers us a glimpse into our shared future. Will our species be able to spread across the cosmos, to colonize other planets, and to preserve our heritage and legacy through the ages? If so, it will only be through the study of astronomy.

Space Exploration

Benefits of space exploration, negatives of space exploration, increase in space exploration and possible future impacts, ways of space exploration with the least damage.

Space exploration is one of the most rapidly developing science which is known for its high financial implications and advanced cutting-edge technologies. Life beyond the planet was always an object of researches and investigation. Many new developments, equipment, and discoveries from space are notably useful and efficient for improving the level and the quality of life on the Earth. The history of that kind of researches started in ancient times when philosophers tried to investigate the night sky to find out the system of stars arrangement. Since then, studies in this field have progressed in a significant way, and now people even have their own space station in Earth orbit. Nowadays, there are specialized organizations such as the Aerospace Industries Association or American Astronautical Society the goal of which is to explore space. The purpose of this paper is to describe the particularities of space exploration, taking into consideration its advantages and disadvantages for humanity, ethical questions, and predictions about the future of this industry.

It is an erroneous belief that the exploration of space does not have any impact on the life of ordinary humans. It improves the quality of the life of millions of people every day: the technologies designed for space studies are now used in the medical sphere and for conducting other experiments (Rai et al., 2016). Nevertheless, space research also poses many ethical questions to society concerning colonization, financial resources, and ecological issues. With the advancement of this science, increasingly more questions rest without any answers. For many people who are not very familiar with the topic, it seems to be a complete waste of the governmental budget and just a way for experts to entertain themselves.

In the era of Gagarin and first trips into space, being a cosmonaut was considered to be highly prestigious, respected, and, at the same time, romantic. At the present moment, this science went too far away frthe om basic understanding that people regret that their taxes are spent on the exploration of the place that they would never visit. The attitude of the researchers in this field is rather ambivalent; the main beneficial and negative points of space exploration would be covered in the next parts to make the argumentative and clear statement.

The investigation of space has many advantages for society despite the fact that they are not highly notable for an ordinary person. For example, space researches encourage studies of different types of science (Panesor, 2009). What is more, the young specialists in chemistry, biology, or engineering become interested in the space sphere (Panesor, 2009). It is profitable for both sides – students provide innovative ideas, and the research centers help the new generation of scientists to get the job and to be well-paid. The benefits of space exploration cannot be counted only in money because the impact on society is non-quantifiable. According to Jacksona et al. (2019), a woman plays a crucial role in space studies. Thanks to women-cosmonauts, the level of social inequality declined rapidly in the last decade of the 20th century. A variety of studies show that women and men think and act in contrasting ways. It helps the industry of space exploration to function in a more efficient way considering several distinct points of view.

Space exploration is often claimed to be the sphere for wasting a large sum of money. This industry is one of the most expensive because of the intellectual resources and high-priced equipment details (“Cost of Space Exploration,” 1961). Nonetheless, Baum (2009) proposes the idea of cost-beneficial analysis; from his point of view, it is necessary to keep in mind the ethical risks and the alternative options of the distribution of the budget. In his other study, he raises the issue of the problem of colonization (Baum, 2016). According to his research, if people cannot save nature on the planet, there is no use to attempt to find other places to live. Moreover, the ecological situation becomes significantly severe because of the desire of humans to leave the Earth.

It is important to mention that the cost of space explorations is not always high. It generally depends on the type of research and its goal (“International Space Exploration Coordination Group,” 2013). If the data of previous experiments were used, it would help to make the price for the surveys lower (Battat, 2012). However, it requires more time and effort from the staff and makes this task, not an easy one. Another disadvantage is that it takes years or even decades for inventions and technologies to be a part of the life of ordinary people. The negatives of space exploration are highly notable for society because they cannot see the real impact.

The industry of space studies plays an essential role in the political, social, and economic spheres. If there were more money invested, it might result in a financial crisis in the country. Even though space exploration is supposed to have many non-material benefits and unexpected advantages in the nearest future. For example, the recent developments would be directly integrated into different fields of science. The robotics like the mechanic hand or neurotransmitter are now saving and improving thousands of Roboticsnks to space technologies. The level of intellectual needs in this sphere would encourage cultural and cognitive growth for many people interested in this area of study (Crawford, 2019). If the specialists would not find any place for colonization, it may influence the attitude of the society to the planet and its beautiful nature. People might become more accurate and carrying about the ecological situation on Earth.

First of all, the previous experience and results should be attentively analyzed to make the price of the new inventions lower. Secondly, there should be specialists in public relations who would explain the society why space explorations are too crucial and what are the benefits of it. Finally, space study should become a global issue for developed countries (Krichevsky, 2018). It would reduce the cost for each separate country and would make the process more efficient.

In the modern world, space exploration has its benefits and negatives. The advantages are mostly non-economical and concern the social sphere of life, while the disadvantages are centered around the high costs of the researches. Nevertheless, there are several ways to improve the financial situation and to make the price lower: by using the experience of previous generations or by optimizing the process. Ethical questions should also be taken into consideration and make humanity reflect on ecological and moral questions. Space study is one of the fascinating spheres of science in the 21st century.

Space tourism: What are the pros and cons?

Space tourism has its fans — and its critics.

Private companies are offering many opportunities to make the leap off Earth , ranging from a quick suborbital hop to a multi month stay on the International Space Station (ISS). But the advent of the space tourism industry has spurred a vigorous debate: Is it helping to propel humanity to the stars , or is it just letting rich people have a little fun while providing no real value?

Here's a look at the pros and cons of space tourism.

Related: How SpaceShipOne's historic launch 20 years ago paved the way for a new space tourism era

The pros of space tourism

A handful of private individuals, colloquially known as space tourists,  managed to purchase tickets to the ISS or Russia's Mir station. However, with the end of the space shuttle program in 2011, NASA canceled any further opportunities. That picture changed with the emergence of private spaceflight companies headed by various billionaires, including Elon Musk's SpaceX , Jeff Bezos' Blue Origin and Richard Branson's Virgin Galactic .

Of the three, only Virgin Galactic has a stated long-term goal of promoting space tourism, offering quick suborbital flights just above the Kármán line — the arbitrary but internationally recognized edge of space. Paying customers can get a similar experience with Blue Origin, but that company hopes to pivot to orbital industries. With SpaceX, you can get a multiday stay in orbit, but you'll have to bid against numerous government contracts for the opportunity.

Promoters of space tourism have suggested various benefits of the industry. For example, many space tourists are actively running and participating in experiments, such as examining the effects of microgravity on human health , plant growth and material properties. This is real science that needs to be done to propel humanity to the stars.

There's also financial propulsion, with hundreds of millions of dollars of investment going into the newfound industry. Companies are developing new equipment, techniques, technologies and more so they can offer tickets to space. And the more we invest in space in general, the better off our shared ventures will be.

The frequent launches of space tourists, including celebrities such as William Shatner , have caught the media by storm. This, in turn, fuels more public interest, which can lead to more discussion, more awareness and more funding.

The cons of space tourism

On the other hand, critics of space tourism point out that the industry is catering solely to exceptionally wealthy individuals. Ironically, this can lead to a sense of public disillusionment with space: Instead of opening it up to everyone, it might cause people to roll their eyes at the inaccessibility. Basically, it's just rich people doing rich-people things.

Because of the enormous cost of a ticket — anywhere from hundreds of thousands to tens of millions of dollars — it's hard for most people to see the value in space tourism as an industry. They simply don't get to participate in it. 

And while some space tourists have conducted experiments during their expeditions, those experiments haven't exactly been revolutionary or consisted of anything that couldn't be done by astronauts on the ISS. So space tourism isn't really advancing human spaceflight in any significant way.

Lastly, space tourism is a niche business. While some companies have developed technologies that are specific to this industry, those technologies will not necessarily transfer to other space-related activities, like industrial or scientific applications. We could be spending all this time, money and resources on a business venture that never grows significantly and never leads to anything else.

The bottom line

The bottom line is that space is hard — it's difficult to get to space, and it's difficult for humans to remain in space for any length of time. Most space tourism companies have folded well before their first attempted launch, and it's not clear that this business niche will grow all that much. Only roughly 60 people have been to space as tourists, and the vast majority of them have gone only on quick suborbital joyrides with a few minutes of weightlessness. 

There are only a few launches, at most, every year dedicated to space tourism, and a peek at planned launch schedules reveals that this number will not change much over the coming years.

— Do space tourists really understand the risk they're taking?

— The rise of space tourism could affect Earth's climate in unforeseen ways, scientists worry

— Most Americans expect routine space tourism by 2073, but few would actually try it  

Most people will never get the opportunity to become a space tourist; it will likely remain a niche industry serving a select set of very wealthy individuals. It's not a game changer in any direction. It will continue to be a component of the overall human interest in space but not a major driver of innovation or expansion.

But hey, if you're ever given the chance, go for it!
