The Story Behind the Legend

In NASA's early missions, astronauts used mechanical pencils. For the Project Gemini program in 1965, NASA purchased 34 mechanical pencils for a total of $4,382.50—about $128.89 each.

This sparked widespread public outrage. NASA immediately began looking for alternatives.

At the same time, Paul S. Fisher of Fisher Pen Co. was developing a ballpoint pen designed specifically for the space environment. The pressurized ink cartridge works in zero gravity, underwater, and at extreme temperatures ranging from -34°C to +120°C.

The development was funded entirely by the company—an investment of about 1 million U.S. dollars without any funding from NASA. After obtaining a patent, Fisher offered the pens to NASA in 1965.

In 1967, after rigorous testing, NASA approved the pens for the Apollo missions. About 400 pens were purchased at a price of $6 each. 🌙

In February 1969, the Soviet Union also purchased 100 ballpoint pens and 1,000 refills for the Soyuz spaceflights. Since then, both American astronauts and Russian cosmonauts have continued to use them.

Frequently Asked Questions

What is the difference between the Fisher Space Pen AG7 and a regular ballpoint pen?

The Fisher Space Pen AG7 uses a special pressurized ink cartridge designed to function in the space environment. Unlike ordinary pens, it writes in zero gravity, underwater, in other liquids, and at extreme temperatures ranging from -34°C to +120°C. The body is made of solid brass with a chrome-plated finish, making it significantly more durable than standard pens. The design has remained unchanged for more than 50 years, which in itself speaks to the reliability of its construction.

Is the Fisher Space Pen AG7 a good gift?

Yes, the AG7 is an excellent gift choice for men and women in a variety of professions. The pen comes in a sturdy, padded gift box along with a brochure detailing the history of the Fisher Space Pen. It’s perfect for teachers, doctors, lawyers, military personnel, police officers, business leaders, high school seniors, and many others. Its history and the technology behind it make it not only a practical gift, but also an interesting and prestigious one.

Why is the Fisher Space Pen AG7 a good choice for doctors?

The pen is so sturdy and durable that it can withstand processing in an autoclave—the device used to sterilize medical instruments. This makes it exceptionally well-suited for use in a medical setting. Its chrome-plated brass construction allows for repeated disinfection without damaging the materials.

What type of refill does the Fisher Space Pen AG7 use?

The AG7 comes with a Fisher Pressurized PR4 refill with black ink and a medium nib. The refill uses pressurized ink, which ensures reliable writing under various conditions—including in cold or hot weather and when held at an angle. Fisher Space Pen refills are standardized and interchangeable.

How does the Fisher Space Pen AG7 mechanism work?

The AG7 features a dual-action mechanism for operating the refill. There is a push button at the top that extends the refill for writing. The side button is used to retract the refill. The mechanism’s special design ensures that the refill is always retracted before the pen is put back in your pocket. This prevents stains on clothing and is a practical solution for everyday use.

What is the history of the Fisher Space Pen AG7 and the Apollo mission?

Paul S. Fisher of Fisher Pen Co. developed the space pen without financial support from NASA, investing approximately $1 million of the company’s own funds. After NASA approved the pens for the Apollo missions in 1967, approximately 400 were purchased at a price of $6 each. The AG7 was used on the Apollo 7 mission in 1968 and has been present on all U.S. manned spaceflights ever since. In 1969, the Soviet Union also purchased 100 pens and 1,000 refills for the Soyuz flights.
