The ballpoint pen is a truly revolutionary invention that made writing widely accessible to the public, and it became a key tool in scientific discoveries as well. Imagine being able to write clearly underwater or even in space. Thanks to these types of pens, now it is possible. They provide a functioning method to document observations in space discovery, aviation, or even deep-sea diving.In this article, you can learn all about the exciting journey of the ballpoint pen from the deepest depths of the ocean to outer space.
The Role of Ballpoint Pens in Aviation
Early aviation heavily relied on writing instruments for recording information and maintaining flight records. Traditional fountain pens were commonly used during this time and prone to leakage or ink spills during flights.
Altitude and air pressure changes led to ink flow issues and messy writing. The ink used in fountain pens could freeze at high altitudes or extremely low temperatures. The ballpoint pen emerged as a solution to the challenges posed by fountain pens.
Ballpoint pens introduced a new mechanism where ink was delivered through a small ball at the tip. This prevented leaks and provided a smoother writing experience. The main advantage of these pen inks is that they are less likely to freeze or experience flow issues in extreme aviation conditions. Also, the ball and socket mechanism prevents ink from leaking, making them more reliable during flights.
The Ballpoint Pen’s Journey into Space
During the space race between the United States and the Soviet Union, space exploration became a top priority. Astronauts required reliable writing instruments to record observations, perform calculations, and document experiments in challenging space conditions.
Pencils were out of the question, as they contain graphite, which conducts electricity and causes a threat to the electronic components. Graphite is also inflammable, so bringing any on a spaceship is unadvised.
Traditional pens relied on gravity to draw ink to the ball, making them ineffective in zero-gravity environments. The pressurized ink cartridge uses nitrogen gas to force the ink towards the ballpoint, allowing it to write in any orientation, including upside down and underwater. One ZEBRA pen also has this feature.
Paul C. Fisher, an inventor and entrepreneur, recognized the need for a pen that could write in zero gravity and extreme conditions. Fisher’s pen, known as the Fisher Space Pen, gained recognition for its reliability in space missions and was adopted by NASA.
There was one significant difference between this pen and a regular ballpoint pen. First, the ink was a thixotropic gel turned into a liquid by pressure. A second method involved forcing the ink against the ball in the pen tip by pressurizing it at two atmospheres (similar to the pressure in car tires).
Ballpoint Pens for Underwater Use
Deep-sea environments experience extreme pressure, which can affect traditional ballpoint pens’ functionality and ink flow. Standard pens are not designed to be waterproof; water can seep into them, causing ink leakage or rendering them unusable underwater. Deep-sea temperatures are often much colder than the surface, affecting ink viscosity and pen performance.
There are ballpoint pens specifically designed for underwater use. These pens are built with seals and mechanisms to prevent water from entering the pen. Underwater pens typically use sealed ink cartridges that avert water from compromising the ink and causing leakage. Underwater pens’ ink is formulated to withstand colder temperatures, preventing ink from thickening or freezing. Operators of submersibles and ROVs commonly use ballpoint pens to annotate maps, record instrument readings, or mark important locations during underwater missions.
From the Deep Waters to Outer Space
The ballpoint pen was, and still is, an important device to make notes during discoveries. While using a fountain pen can be messy in our everyday lives, using one underwater or in space is impossible due to the pressure and temperature difference. Due to their design, ballpoint pens are less likely to start leaking and are generally more reliable than other types. A special kind used during space discovery works perfectly even in extreme conditions, with no gravity. The underwater types have different seals and mechanisms to provide good functionality.
