Pros and Cons of Space Exploration

Space exploration is a hot topic these days. But are we ready for it? Some say yes, some say no. So let’s take a look at the pros and cons of space exploration to see where we really stand on this issue.


Space exploration has many upsides. It’s a great way to advance technology, inspire future generations, and create jobs. The United States also benefits from international cooperation and national pride. And there are many more pros!

Advancement of technology

One of the most obvious pros and cons of space exploration is that it advances technology. There are many examples of developments on Earth that have been inspired by space-related activities, such as the development of GPS and touchscreen displays. In addition to this, new technology developed for use in space has also been used on our planet, such as memory foam mattresses (which were created by NASA).

There are also several examples of scientific discoveries made through space exploration; some examples include:

  • The discovery that there is water on mars, which could be used for future colonization efforts or even resource utilization
  • The discovery of dark matter in the universe – this gives us more insight into how it works and what its purpose may be (for example dark matter may be responsible for holding galaxies together)

Scientific discoveries

You may have seen some of the scientific discoveries from space in movies like Gravity or even on your own planet’s news, but there are still many more to come. In fact, some pretty cool ones have already happened:

  • We learned about our Earth’s magnetic field and how it protects us from solar radiation.
  • We discovered that Jupiter has a faint ring system with at least three rings called propellers (they’re named after the propeller-shaped clouds they were first seen behind).
  • Pluto has moons! This was an exciting announcement because it meant that Pluto was no longer classified as a planet but rather a dwarf planet (which is okay).

Inspiration for future generations

  • Inspiration for future generations. In many ways, space exploration is a great thing because it inspires children to study science and engineering. It also inspires people to think about the future, which can be a good thing when done correctly.
  • Space exploration inspires people to dream big, which can be a good thing when done correctly
  • Space exploration is sometimes cited as inspiring curiosity about the world in general

Job creation

Space exploration creates jobs.

Here are some examples of space-related jobs:

Astronaut (1) – In order to go into space, you need someone who can go into space and do things while they’re there. These people have to have a certain set of skills, like being able to pilot spacecrafts or repair them if something breaks. They also need good vision, because looking out the window for hours on end can take its toll on your eyesight! Astronauts also have to be prepared for any potential emergencies that might arise mid-flight; luckily their training helps them avoid most accidents!

Mission Control Operator (2) – This person coordinates all activities between mission control and the astronauts themselves. Their main responsibility is monitoring everything that goes on during a mission—they make sure everyone involved has what they need from one another so that nothing goes wrong during takeoff or landing stages!

National pride

  • National pride is a positive thing.
  • National pride can be a negative thing.

International cooperation

  • International cooperation: Space exploration is a global endeavor, and international cooperation is essential for its success. It’s not just that countries need to work together to launch rockets or control the ISS; NASA also relies on other countries for scientific research. This allows NASA to get more done with less money, since they don’t have to develop every tool themselves. In fact, this kind of cooperation has produced some of the biggest breakthroughs in space science and exploration over the years. For example:
  • The Hubble Telescope was an international effort between NASA and ESA (European Space Agency).
  • Scientific discoveries: International space missions have generated many new insights into how planets form and evolve—and even how life can survive in extreme conditions like those on Mars. Both NASA’s Viking landers from 1976 as well as ESA’s Mars Express orbiter from 2003 found evidence suggesting that there may once have been liquid water on the red planet’s surface; however, they could not determine whether it had occurred recently enough for life forms such as bacteria or algae to exist there today (which means we’ll probably have plenty more questions waiting when humans do eventually set foot on Mars).

Understanding of earth and its place in the universe

Space exploration is important because it helps us to understand what we are a part of. Our planet is a tiny speck in the universe and we need to know more about our place in it. Understanding our place in the solar system, galaxy and universe will help us understand how large and small everything really is. It will also help us understand how important earth is, but also how insignificant humans may be when compared with other planets, stars and galaxies (we are just one small planet).

Resource utilization

  • Mining
  • Space tourism
  • Space farming
  • Space solar power
  • Exploration

Environmental monitoring

  • Environmental monitoring is a great benefit of space exploration.
  • Monitoring the earth’s environment is important for our survival.
  • Space exploration has allowed us to learn more about our planet and its current health, helping us better understand how things like climate change or pollution affect life here on Earth.

Potential for colonization

Colonization of our solar system is the most exciting prospect related to space exploration. We have all kinds of questions about what life might be like on other planets, and we’ve never been able to go beyond our planet’s atmosphere or far enough away from Earth to answer them. Colonization would allow us to explore these questions in person!

One example of a place that could potentially be colonized is Mars, which has a surface temperature so cold that liquid water cannot exist there except as ice or vapor. However, if we were able to warm up the planet just enough—perhaps with an artificial greenhouse effect—water would become liquid again, allowing humans (or perhaps even plants) to live there comfortably! Another option would be Venus, which has similar conditions but is further away from the Sun than Mars; its thick clouds prevent us from seeing below them into its atmosphere.


The cons are many, and they’re as diverse as they are scary. For example:

  • High cost! It’s expensive to put people into space. Just ask NASA, which has spent tens of billions of dollars on the International Space Station since 1998 without making enough money back to pay for anything else.
  • Risk of human error! As everyone who’s ever watched a sci-fi movie knows, the human body is full of tubes that can explode if you look at them wrong or eat too much pizza—and when you’re stuck in a tin can for months at a time with no gravity holding down your internal organs, that kind of thing happens all the time. If you’re going to be spending hours upon hours every day floating around doing nothing but waiting for something bad (or worse) to happen to you, it would help if there weren’t any humans involved at all!
  • Risk of equipment failure! You’ve probably heard about how expensive rockets are—and it doesn’t stop there: equipment malfunctions happen all the time too (especially when NASA engineers start drinking before work). So unless we want our astronauts’ bodies floating out into space forever with no way home whatsoever

High cost

Space travel is expensive, but that’s not the only reason you should be wary of it. The cost of space exploration is high because of the many risks involved. Space exploration involves complicated technology, which can fail at any moment and send you back to Earth with nothing to show for your efforts. And if your equipment fails in space, there’s no hope of repair or replacement—you’ll have to make do with whatever parts are left behind. But even if everything goes according to plan and you make it safely back home after a few months in orbit around Earth…

…Well then you’ll still have trouble finding someone willing to fund another trip for some time! After all, how many people want their money wasted on something as absurd as flying into outer space?

Risk of human error

Space exploration has many risks, but perhaps the most obvious one is human error. As you might have guessed from the name, NASA is an agency of the United States government; therefore all its employees are government employees and subject to government oversight. While this isn’t necessarily a bad thing overall (for instance, it means that astronauts have access to health insurance), it does mean that any accidents or mistakes made on mission would be heavily scrutinized by Congress and the public alike. In fact, some argue that this scrutiny could actually be detrimental—that if astronauts knew they’d be held accountable for every mistake they made while in space (even small ones), they might be hesitant or nervous enough not to take necessary risks during their missions out of fear of being punished upon their return home.

Risk of equipment failure

The risk of equipment failure is high. What are the consequences of equipment failure? Equipment that fails in space could hurt an astronaut or damage a valuable scientific instrument. How can this be prevented?

We need to ensure that all our equipment is properly tested before it’s sent into space, and we should keep careful track of all parts so we know if any have gone missing or broken down.

Risk of space debris

Space debris is a real problem. It poses a threat to satellites, space stations and astronauts. It can be made up of old satellites, rocket stages, small pieces of metal and other junk. Space debris is dangerous because it moves at very high speeds (some as fast as 17,000 mph) which could cause serious damage to spacecrafts or even worse people in them!

This problem has only gotten worse since the beginning of human space missions. In fact, today we track about 22 thousand objects in Earth orbit that are larger than 4 inches across! That’s enough stuff up there to clog up everything from GPS navigation systems to cell phone signals if any one piece were ever allowed to collide with something important like say…the International Space Station (ISS).

Risk of space warfare

Space is a valuable resource. It’s not surprising that we’re seeing new efforts to expand out into the universe, as well as protect what we have here on Earth. The very fact that there’s so much untapped potential out there means that we’ll have to work with other countries and organizations in order to harness it safely and responsibly. The risk of space warfare is one of the biggest cons of space exploration in general—but it’s also one of its greatest potential benefits!

Risk of environmental damage

While all of the pros listed above are major selling points for space exploration, it’s important to keep in mind that there are some negatives as well. For example, while NASA has made significant progress towards cleaning up their own messes, we must still be aware of what impact human activities have had on Earth’s environment. The risk of environmental damage is also high when you consider how many satellites have been launched into space over the years and how much space debris they have left behind as they burned up in our atmosphere or crashed into one another. However, this doesn’t mean that we can’t use current technology to help us better understand our planet!

Risk of political tension

Space exploration is a global effort. The International Space Station (ISS), which has been continuously occupied by humans since 2000, is owned and operated by the United States, Russia, Japan, Canada and 11 member states of the European Space Agency (ESA). The ISS orbits Earth at an altitude of between 330 and 435 kilometers (205 to 270 miles). As a result of this international cooperation, several nations have already agreed on how they should manage outer space activities—and if we want to continue our efforts in exploring outer space, it’s important to continue these agreements.

Developing countries are often excluded from discussions about space exploration because they cannot afford it; however, this does not mean that these countries are not interested in participating in programs related to astronomy or astrophysics research—they would just need more financial support from developed nations such as Australia or Japan before doing so could become feasible.

Risk of exploitation

The risk of exploitation is a serious danger that comes from the very nature of space exploration. Resources, people, and the environment are all at risk for exploitation. We’ve seen it happen time and again here on Earth—people who have had their lives turned upside down by natural disasters or economic hardship can be taken advantage of by others in more stable positions. In such situations, we’ve seen opportunistic individuals take advantage of desperate ones to make money or get power. In the same way that our media portrayals help define what it means to be “American,” they also help shape how we think about other peoples—and while this may seem benign or even beneficial at first glance (for instance, if you watch TV shows like Star Trek), it can pave the way for prejudice and discrimination later on when those same ideas become ingrained in society as well as individual mindsets (e.g., white people are superior; men are stronger than women).

Risk of cultural impact

If you’re a fan of science fiction, the idea of space exploration has probably piqued your interest at least once in your life. It’s hard to deny that it sounds pretty cool. But what are the real pros and cons of space exploration? Let’s take a look:

  • Pros: Advancement of technology, Scientific discoveries, Inspiration for future generations, Job creation and National pride
  • Cons: High cost and Risk of human error (and other stuff).

Risk of unknown consequences

In the 21st century, there are many risks associated with space exploration. Some of these include:

  • High cost: Space travel costs a lot of money, and private investors may not be willing to invest in projects that don’t have a guaranteed return on their investment.
  • Risk of human error: One thing we’ve learned about humans is that mistakes happen all the time—and sometimes they’re fatal! That said, accidents do happen when people are working in dangerous environments like outer space (just ask Apollo 13). This means that we need to plan carefully so that any accidents can be avoided or mitigated as much as possible during missions. And if something does go wrong? We’ll have no choice but to deal with it!
  • Risk of equipment failure: In addition to human error, there’s also always going to be some risk when dealing with technology—even top-of-the line stuff like NASA’s probes aren’t perfect yet! If something goes wrong while exploring new worlds or discovering alien life forms…well then we’re really gonna have our hands full trying figure out what went wrong because most likely nothing has ever happened before this moment in history!


While there are many benefits to space exploration, the risks are great and may outweigh the rewards. We need to think long and hard before we send humans into space so we can ensure that the possible benefits outweigh the potential harm it could cause.
