History of the Fisher Space Pen

During the early NASA missions, astronauts used pencils. In 1965, Paul S. Fisher designed a pen that works in zero gravity, underwater, and at extreme temperatures. The company invested about $1 million of its own funds, without any funding from NASA.

In 1967, NASA equipped the astronauts on the Apollo mission with these pens. In February 1969, the Soviet Union also purchased 100 pens and 1,000 refills for the Soyuz spaceflights. To this day, American astronauts and Russian cosmonauts use them in orbit.

Frequently Asked Questions

What does "thixotropic ink" mean in the context of the Fisher Space Pen Infinium?

Thixotropic ink is a special formula in which the ink remains in a solid or gel-like state until the pen is used. When writing, the pressure of the ball against the paper liquefies the ink, allowing it to flow smoothly. This prevents leakage at high temperatures and freezing in cold weather. It is this technology that allows the pen to perform reliably in a temperature range from -34°C to +120°C. You don’t need to shake or warm it up before use—it works right away.

Is the Fisher Infinium INFGTN-1 battery pack replaceable?

No. The Infinium series cartridge is built-in and is not designed to be replaced. It is designed so that, under normal use, the ink will last for the entire lifetime of the user. The cartridge lasts up to three times longer than standard ink. The built-in pressurized nitrogen gas cartridge ensures a constant and even flow of ink, regardless of the writing angle.

What is a titanium nitride coating, and what makes it special?

Titanium nitride is an extremely hard and abrasion-resistant coating used in the medical industry to coat implants and in the aerospace industry to protect parts from abrasion. On the Fisher Infinium INFGTN-1 pen, it has a gold-colored finish and provides high resistance to scratches and wear during daily use. It is one of the highest-quality coatings applied to writing instruments.

Is the Fisher Space Pen Infinium a good gift?

Yes, absolutely. The pen comes in a luxurious gift box and is ready to give as a gift without any additional wrapping. It’s suitable for men and women in various professions—doctors, lawyers, military personnel, police officers, teachers, business leaders, and high school seniors. The brand’s history, technology, and exceptional finish make it an excellent conversation starter and an unforgettable gift. At Dulotec.COM, you’ll find this pen at a great price with fast shipping.

What is the warranty on the Fisher Space Pen Infinium?

Every Fisher Space Pen is precision-assembled, hand-tested, and comes with a lifetime warranty against all manufacturing defects. This is the manufacturer’s commitment to product quality. The warranty covers defects in materials and workmanship but does not cover damage resulting from misuse.

Can the Fisher Space Pen Infinium write underwater or in zero gravity?

Yes. The technology of the pressurized nitrogen gas cartridge allows for writing underwater, in zero gravity, and at any angle—including with the pen upside down. This feature is why NASA equipped the astronauts on the Apollo missions with Fisher Space Pens. Later, the Soviet Union also purchased these pens for its Soyuz spaceflights.

The pen is compact and easy to carry. When extended, it is 14.1 cm long, and when retracted, it is 11 cm long. Its diameter is 11.9 mm. These dimensions make it easy to fit in a wallet, organizer, or pocket. The clip allows you to attach it to the edge of a pocket or backpack for added convenience.
