List of the Advantages of Space Exploration
1. Space exploration allows us to prepare for potential hazards.
The universe is a vast place where hidden dangers could be lurking almost anywhere. 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. Oumuamua, or 11/2018 U1, was discovered by the Pan-STARRS1 telescope in 2017 by the University of Hawaii through funding from the Near-Earth Object Observations Program. 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.
2. 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.
3. 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.
4. 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 0.12 pixel crescent. 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.
“Look again at that dot,” wrote Sagan. “That’s here. That’s home. That’s us. 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.”
5. 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.
6. Investments into space exploration create real economic benefits at home.
The governments which provide the majority of our space exploration infrastructure employ over 20,000 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. Even though many of these programs receive taxpayer funding, the wages, manufacturing, and indirect investments contribute over 70% more in overall value at the local level compared to each dollar spent in the United States. These opportunities allows us to explore many different fields of study in addition to what is waiting in the universe as well.
7. Anyone can become a space explorer.
Space exploration doesn’t need to involve starships, space stations, or intergalactic travel. 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. We have made some incredible discoveries with this technology already.
- We have a better idea about the age of the universe (around 13.7 billion years).
- Images of the deep universe show that there are thousands of galaxies out there.
- It helped us to discover four of the five moons that orbit Pluto.
- We have a better understanding of planetary seasons in our universe.
- It works to peer into the atmospheres of alien planets so that we know what is waiting for us in our future exploration efforts.
8. Space exploration encourages us to share instead of being selfish.
Being human-first from a space exploration standpoint isn’t about dominating other cultures that we might find waiting for us in the universe. 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. This advantage won’t solve our problems, but it can shift our attitude toward something that is healthier than our current state.
9. 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.
List of the Disadvantages of Space Exploration
1. Our current technology makes it dangerous to get into space in the first place.
Several agencies are developing “space tourism” packages that can take people in a comfortable aircraft to the very outer layers of our atmosphere, but that is not an exploration effort. 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-38 in October 1964, there have been over 20 individuals who lost their lives in the line of duty while advancing U.S. space program interests. 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.
2. 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. When the space shuttle program was active in the United States, the total cost of the launch was about $500 million. That figure does not include the expenses of postponement that often occurred because the conditions were not right to send a rocket into space.
Manned missions in our solar system could cost 10 times that amount, and that might get us to Mars or one of Jupiter’s moons. 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.
3. Astronauts receive exposure to natural dangers while in space.
If the launching process doesn’t kill you during a manned space exploration effort, then the natural dangers that are present outside of our planet’s atmosphere could become problematic in a variety of ways. 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.
4. Current space exploration efforts could be a one-way trip.
When we sent astronauts to the moon, our technology provided them with a chance to land on the surface and return to their spacecraft. It is possible that we could perform a similar action for asteroids, moons around other planets, and other celestial bodies that do not have an atmosphere. If we are going to start exploring Mars, then that journey could be a one-way trip for the astronauts.
Even if this journey does not become a one-way trip, the amount of time necessary to reach a destination beyond the moon makes it virtually impossible to mount a rescue mission if something goes wrong. Our current vision of space exploration requires perfection to create a successful result.
5. There may not be a reason to start exploring at this time.
Human cultures have always had a fascination with exploring space because it satisfies our need to learn more about the universe. Taking long-distance pictures with the Hubble telescope is not the same as visiting the location in-person. What we must ask ourselves right now is if there is a valid reason to begin this effort, and the truth is that there are few pragmatic applications to consider.
We could start mining asteroids for their raw materials and mineral content in the future. Planetary colonization could be necessary in future generations. Since we are still dealing with issues like crime and poverty here at home, addressing our immediate concerns might be better than looking at future needs which might never be necessary.
6. Unmanned probes are even a waste of resources.
One of the ways that we attempt to limit expenses with our space travel needs is to send unmanned probes into the dark vastness that lies beyond. There have been some successes with these efforts, most notably the Voyager 1 and Voyager 2 missions that allow us to peer outside of our solar system. This option allows us to almost eliminate the risk to human life entirely as well.
There are also disadvantages to consider with this approach, starting with the fact that there is little adaptability to changing circumstances. The Mars Climate Orbiter is an excellent example of this problem. When it received incorrect coordinates for landing, it burned up while entering the atmosphere before sending any data at a cost of more than $120 million.
7. Our current information is well out-of-date.
On February 22, 2017, NASA announced that it had found seven planets the size of Earth in a single solar system. Three of the planets were in the so-called Goldilocks Zone, which means they are at a distance from their star that is not too hot and not too cold. It is called the Trappist-1 group, and this set of planets lies in the Aquarius system. That’s about 235 trillion miles away, which is at least a measurable distance.
The problem is that this planetary system is 40 light-years away from us. That means the information that we can observe right now took forty years to get to our scientists. Think about all of the changes that have happened in your life in just the past 5 years, and then apply that concept to a planetary scale. When we start exploring space, we must take into account that this delay is present so that we don’t fly into an unexpectedly dangerous situation.
8. It may lead us into future conflict with beings who have superior technology.
Space exploration makes us think in noble terms about what lies in wait for us in the universe. When we sent the Voyager spacecraft into our solar system and beyond, there were two records placed on the devices to communicate with whoever might find them to let that intelligent life know that we exist.
Most theorists who seriously consider the pros and cons of meeting alien life say that there are only two possible outcomes that can occur with first contact. That alien species will either be so advanced that their technological presence as led to a peaceful society where an exchange of information may one day be possible, or it will be aggressive and want to access our planetary resources.
9. Space exploration creates a lot of trash around our planet.
There are over half-a-million items of trash from over 50 years of space travel and satellite placement which orbit our planet right now. Unless these items fall into the atmosphere and burn up, they will stay in place forever. The ring of debris that we have created makes space exploration more dangerous because an impact with a ship’s hull could have deadly results. We will need to clean up this mess in the future to provide better safety to our future explorers, and we have no idea what the expense might be.
Verdict on the Advantages and Disadvantages of Space Exploration
Space exploration is beneficial even if we only look at it through the lens of hope. It is an idea that unites us as one race instead of over 190 different countries. We can proceed into the universe as one people, taking the first steps toward new experiences just like we did when we placed astronauts on the moon for the first time.
Explorers always face danger, and space is no exception to that rule. The vacuum of the universe was not meant for humans, which means we must constantly adapt and protect ourselves when we are outside of our atmosphere. Then there is the risk of an encounter with alien life to consider too.
The advantages and disadvantages of space exploration must come from a common sense perspective. Other races could harm us, but there is also the possibility that we could be dangerous to other life as well. We should continue with these efforts, but with the understanding that this work is not a race. It is a cooperative effort that will eventually define our humanity.
