From our earliest days, humans have looked to the stars for answers. Space has been a continuous fascination and a source of wonderment, mystery and, in many ways, fear.
It's the great unknown, the true frontier, making it both captivating and terrifying.
Space encapsulates the most fundamental questions of life: Are we alone in the universe? How did we come to be? Why are we here?
To look to space is to ask these questions, to enter is to search for the answers. Over the course of the past century, humans have made incredible leaps forward in this regard, which was particularly evident once again on July 14, 2015.
After traveling for more than nine years and three billion miles, NASA's New Horizons spacecraft finally made its flyby of Pluto on Tuesday, the New York Times reports.
At approximately 7:49 am, traveling at approximately 30,000 mph, it made history by getting the closest a spacecraft has ever been to the dwarf planet, around 7,800 miles away.
We've now seen Pluto up close for the first time:
This is an incredible scientific achievement and a testament to human ingenuity.
It's also a vital event in the history of space exploration, as no space mission has ever traveled to and explored a world so far from Earth.
As NASA Administrator Charles Bolden stated:
While this is an especially proud moment for NASA and the US, it's a feat for all humans to celebrate.
It might sound dramatic, but space exploration is crucial to our survival as a species.
To borrow from Stephen Hawking:
This is a fair assertion, particularly when you look at the detrimental impact humans are currently having on their home planet.
The sad fact is many of our activities are fatal to the natural world, and we're jeopardizing our own survival as a consequence.
As we seek to improve our relationship with the environment and rise to the challenges climate change presents, we can't afford to ignore the importance of space exploration.
Humans have survived and thrived because of innovation and scientific advancement.
Space exploration plays a vital role in catalyzing scientific discovery, and it's important we continue to support it.
No one explains it better than world-renowned astrophysicist Neil deGrasse Tyson:
In the US especially, where students are lagging behind the rest of the world in science and math, we need to get young people more interested in science.
As Tyson aptly notes, space exploration is one of the best means of accomplishing this.
We also make incredibly significant discoveries via exploration itself.
Research on Mars and its climate will help us better understand our own, putting us in a better position to combat climate change.
Furthermore, scientists believe the recent and remarkable comet landing, for example, will give us a better idea of how the Earth formed.
Thus, space travel is fundamentally about understanding who, what and why we are.
Moreover, as the Council on Foreign Relations highlights, many important medical advancements, including improvements to artificial hearts and mammograms as well as laser eye surgery, were derived from space technologies.
A number of popular household items, including vacuums and memory foam mattresses, are also linked to NASA.
In other words, space-related research is abundantly beneficial.
But over the years, NASA has been made less of a priority, seeing significant cuts to funding.
We are doing a disservice to ourselves by not providing NASA with the support it needs to further scientific innovation and discovery.
Space exploration is becoming increasingly commercialized, with private companies playing a large role. Many, including Neil deGrasse Tyson, believe it would be a mistake not to have NASA, with its expertise and experience, at the center of these initiatives.
Recently, there has been a lot of debate in Congress over how the limited funds appropriated for NASA should be distributed.
This has included heated discourse over the allocation of money for NASA's earth sciences programs.
The fact of the matter is both earth sciences and space exploration are important, and NASA simply needs more funding in general.
Simply put, the health of our planet and humanity's long-term survival depends on keeping a watchful eye on Earth while also looking beyond it.
NASA plays an imperative role in this endeavor, particularly via space travel.
Perhaps most importantly, space exploration helps us recognize our place in the universe, diminishing our egos while helping us overcome our petty differences.
In the words of Carl Sagan:
We are simply a small, but interconnected, part of something more vast than we can begin to comprehend.
If we can recognize this, the disputes that plague our world might finally begin to dissipate.
