5 Things We Have Thanks to Space Exploration

5 Things We Have Thanks to Space Exploration

In a time when economic austerity is en vogue, we find ourselves debating what is worth spending money on and what isn’t. Programs have to justify their existence and those programs that are seen as ancillary or superfluous get the ax. Unfortunately, often science that doesn’t have an immediate practical use is seen as fluff and a waste of time and money. In the United States, NASA can be an object of this debate. We should not be exploring the solar system, some say, when we have so many problems on the Earth. This, I believe, is an incredibly myopic point of view that ignores the myriad of technological advances that make our lives longer, safer, and more fun made possible by the space program.

Cell Phone Camera

You know how you basically can’t buy a cell phone anymore without a camera? Yeah, you can thank NASA for that. In the 1960s, engineers at the Jet Propulsion Laboratory (JPL) first developed the concept of the digital camera. In the 1990s, a team at the JPL worked to create cameras that are small enough to fit on spacecraft while maintaining scientific quality. One third of cell phone cameras contain the technology developed from this research.

Clean Energy Technology

Not every piece of technology is directly applicable to non-space faring activities. But, more often than not, technology developed for space flight is refined to create something useful for us land lubbers. For example, the company that developed the Space Shuttle Main Engine is using the expertise gained to create clean energy technology that would decrease carbon emissions by 10 percent, the equivalent of taking 50,000 cars off the road.

Scratch-Resistant Lenses

In an attempt to find diamond-hard coatings for aerospace systems, the Lewis Research Center contributed to making sunglass lenses more resistant to scratches and spotting. A technique for creating diamond-hard coatings was developed and patented, and in the late 1980s Air Products and Chemicals, Inc. got a license to use the patent. The technique was further developed and later used to make lenses that are scratch-resistant and shed water more easily.

Water Filtration and Purification

Lest you think NASA tech is just used for superficial creature comforts, think again. NASA has contributed quite a lot to the development of water purification technology over the years. Just by necessity, NASA developed ways to filter water for manned space missions. But that’s not all. Water purification technology also helped treat contaminated water after the 2010 Deepwater Horizon oil spill off the Gulf of Mexico. Furthermore, technology developed to purify water on Apollo spacecraft is now used to purify dolphin tanks and is an alternative to chemical disinfectants.

CAT Scans

A space program needs a pretty good digital image analysis to locate and measure objects. Digital imaging is the computer processed numerical representation of physical images. The JPL played a lead role in developing this technology. This has proven incredibly useful in a variety of medical technologies, like CAT scanners, radiography and microscopy.

These are just a very few of the derivative technologies that we have thanks to investment in space exploration. You can find many more on the NASA website. But, at the risk of sounding like a new age hippie, these ignore perhaps the most important impact a robust space program can have: inspiration.

Space is undeniably huge and strange and beautiful. It’s a mistake to think of the study of space as esoteric. Billions and billions of years ago, supernovae exploded and littered the universe with the elements necessary to create the Earth and everything on it. We literally owe our existence to dying stars. It’s what Carl Sagan meant when he said that we are made of star stuff. The study of space is the study of us and our place in space and time. These are questions philosophers and theologians have been pondering for millennia, and these questions have answers. All we have to do is invest in finding the answers.

I know of no astronaut who returns from space after seeing the Earth with no artificial borders and advocates that we become more divided, more hostile, or more petty. There is something about knowing that we are on an insignificant pale blue dot in an insignificant galaxy that makes one realize how special life is. And we wouldn’t even have a clue if not for our ability to explore our corner of space.

i couldn't even imagine that all of these thinkgs were made because of space exporation :)

If these benefits are from our space program, why are we outsourcing it to Russia now?

DARPA also does research with spin off. Right now they are working on bio-diesel from algae as a renewable substitute for petroleum diesel, In about another 8 years they should have a commercial proudct cost-competitive with petroleum. Not only renewable and cost-competitive but CARBON NEGATIVE.

Like Daniel G states, Very few citizens are aware of how much our space program benefits us on a daily basis. Much of our modern technologies were first pioneered through the space program. And we're slowly abandoning it.

I had no idea that so many things came from technologies developed for space exploration. I am one in the past has said that getting our own planet in working order should be our first order of business. But I amend that now and marvel at the creative "geniuses" that develop these applications!

And yes Daniel G, the article may fall short of so many other technologies that where developed through NASA that we certainly use every day and barely even think about, but we can use our curiousity to read further on the internet. That is assuming some have that initiative.

One specific NASA and Golf connection: Dave Pelz ( was an Engineer and Senior Scientist at Goddard Space Flight Center from 1961 to 1976. He left NASA then to pursue development and marketing of his golf-related ideas and inventions. He is still at it.

This article falls so short of so many other technologies that where developed through NASA that we certainly use every day and barely even think about.

Fuel cells, ballpoint pens, velcro, special materials to extend the limits of what we take into consideration are often times used or where developed specifically for NASA.

In fact, if you want to see some of the potential in materials engineering, you just have to look at NASA and golf. (the latter I have still to find an answer, I have never found golf to be too interesting but it seems like some of the cutting edge materials with the most amazing properties eventually find the majority of their market in golf clubs and golf balls, that makes me sad, perhaps its due to the cuts on NASA over the past several years).

But yes, indeed, the economic benefit we have received from inventions that came out of NASA merits perhaps a large chunk for the United States economic power status, that and the interstate highway system that made it possible for goods to travel from one point to the other faster and more efficiently.

What is sad is that we are losing our standing very quickly as we allow our bridges to deteriorate and fall apart, our rail way system now operates at a slower pace than it did a few decades ago., etc., and we are falling behind in all those critical fields to other countries that are investing more of their money on those technologies.

Wow that's so cool! Some of those things are things I see or use everyday!
