Paul C. Fisher designed the pressurized
refill technology over 50 years ago. The
original space pen
also know as the Astronaut pen was brought to market in 1948.
Further developement was undertaken to improve the
pressurized refills
, ball point and ink technology.

The main technology behind the pen is
the
pressuirzed refill.
The ballpoint is made from tungsten carbide and is precisely fitted in order to
avoid leaks. A sliding float separates the ink from the pressurized gas. The
thixotropic ink in the hermetically sealed and pressurized reservoir is claimed
to write for three times longer than a standard ballpoint pen. The pen can write
at altitudes up to 12,500 feet (3810 m). The ink is forced out by compressed air
at a pressure of nearly 35 pounds per square inch (240 kPa). Operating
temperatures range from -30 to 250 degrees Fahrenheit (-35 to 120 degrees
Celsius). The pen has an estimated shelf life of 100 years.
The refills come with a Parker style adapter allowing it to fit most ball point
pens, not just to be used in the Space pens range.
"It’s a
story that hasn’t circulated outside the inner circles of the U.S. Space
program, but a ball-point pen helped the original Moon-Landing astronauts, Neil
Armstrong and Edwin (Buzz) Aldrin get back to Earth. A spokesman for NASA
recounted the story for Paul C. Fisher. Up there on the
moon, when the astronauts were climbing back into the LEM module, the life
support system backpack brushed against the plastic arming switch and broke
it...."
