When it comes to a business with a great claim to fame, it is hard to beat Fisher Space Pens. That is because Fisher Space Pens invented the pen used by astronauts in space to this day. Made in the USA, Fisher Space Pens have become synonymous with exploration, dependability, and history (Gene Rodenberry would be proud). To cover it all and talk about what personalized Fisher pens are now available at Dayspring Pens, I will blast right off: The History of Fisher Space Pens What’s So Special About Them Personalized Fisher Space Pens Available at Dayspring Pens History of Fisher Space Pens The story goes that NASA looked into a pen for space travel, but it was just too expensive to research and develop. Why not just use pencils? Well, they did. But, there were issues with graphite dust affecting electronics in zero gravity, lead breaking, flammable wood, and smudging making record keeping a little less than permanent. Enter: Paul C. Fisher and the creation of zero gravity writing. Zero Gravity Writing To understand the problem with writing in space, we have to understand how ballpoint pens work. Gravity pulls the oil-based ink down the refill to the tip of the pen. Unfortunately, one of the many things space lacks…is gravity…meaning there was no way for the ink to actually move through the pen to write. Now, Paul C. Fisher was an American businessman and inventor who decided quite on his own to tackle this problem. He did it by creating the pressurized ink refill that would push a new kind of ink out of the pen while writing instead of needing ink to be drawn out of the pen by gravity. Fisher submitted his pen to NASA. They did extensive testing. And the AG7 “anti-gravity” pen became the official Space Pen in 1966. Fun Fact: In 1969, the Soviet Union purchased 100 space pens and began to use them on their Soyuz missions. The Bullet Space Pen: Work of Art Paul Fisher’s success did not stop with the AG7 Original Space Pen. In 1948, the concept of the Bullet Space Pen was born and by the 1990s when people talked about a space pen, chances are they were thinking about the Bullet Space Pen, not the AG7 actually used by astronauts. A collapsible pen filled with the same zero-gravity ink synonymous with Fisher, the Bullet pen captured American culture with its minimalist, industrial design and ability to write at any angle. Learn More: The MOMA permanently exhibits the Bullet Space Pen as an example of industrial art. It was so popular by 1991, Seinfeld created an entire episode titled “The Pen”. What’s So Special About the Fisher Space Pen? So it writes in space and has a good story…is it actually that good a pen? Yes. It is. And it doesn’t just write in space. It also has the ability to write underwater, in extreme temperatures from -30 to +250 degrees Fahrenheit, and to write in greasy environments. This is all because Paul Fisher invented thixotropic ink and that aforementioned pressurized ink refill. Pressurized Ink Refill What is thixotropic ink and what does that have to do with the pressurized ink refill? Bear with me a moment. A thixotropic liquid is a liquid that is so thick it is basically a solid. But, if stress or force is applied to the “liquid” it begins to flow, becoming more liquidity. So when thixotropic ink is put under pressure, it flows like liquid ink. The pressurized ink refill serves two purposes. It keeps the ink in a more liquid state and does not require gravity to write since the pressure pushes the ink out instead of creating a vacuum. The other boon to thixotropic ink is that outside conditions like temperature or water do not affect it since they are not creating stress on it. It’s actually really, really neat, and why Fisher Space Pens have become so useful outside of astronauts in space, because people need to write in less than ideal environments at times. EDC Pens Hence, these handy Fisher ballpoint pens have now become some of the leading Everyday Carry (EDC) pens on the market. When you need a pen that will write no matter what condition you are in, the Fisher pressurized refill will do it. Fisher Space Pen realized the unique capabilities of their pens and started creating durable barrels that could take rough situations without breaking.
