Pencils in Space: What NASA Actually Used Before the Space Pen

The most famous story about writing in space is also one of the most misleading.

According to the popular version, NASA spent millions of dollars inventing a pen that could write in zero gravity while Soviet cosmonauts solved the same problem with an ordinary pencil. The real history is more interesting. Both Americans and Soviets used pencils, NASA later adopted the Fisher Space Pen, and the pen itself was developed privately rather than through a multimillion-dollar NASA invention program.

Pencils were present in the American space program from the beginning. The Smithsonian preserves a notepad and pencil issued to John Glenn for the Friendship 7 mission in February 1962. The pencil was attached with nylon cord so it would not float away, an early example of how even a familiar writing tool had to be adapted for microgravity.

NASA continued using pencils during Project Gemini. Mechanical pencils were attached to spacecraft interiors with retractable cords, allowing astronauts to make notes, record anomalies, and work with flight documents without losing the writing instrument inside the cabin.

The choice of a mechanical pencil made sense. It avoided the need for a sharpener, provided a consistently narrow point, and could be built in a sturdy metal body. But it was not a perfect solution.

Broken graphite was the main concern.

On Earth, a snapped piece of lead falls onto a desk. In microgravity, it can float through the cabin. NASA later explained that loose conductive graphite fragments could threaten switches and electronics. Wooden pencils also introduced combustible material and possible shavings.

The pencil problem was therefore not that graphite stopped working in space. Graphite works perfectly well without gravity.

The problem was what happened when pieces of it escaped.

NASA also encountered another issue: cost. The National Air and Space Museum records that the agency bought 34 mechanical pencils from Tycam Engineering Manufacturing for $4,382.50, equivalent to $128.89 per pencil at the time. That purchase later attracted criticism.

The Apollo program still carried mechanical pencils.

One of the best documented examples is the Garland 35-P. The Smithsonian preserves Garland mechanical pencils associated with Apollo 11, including examples connected with Michael Collins. These were polished chrome pencils with a twist mechanism for advancing the lead.

NASA purchased Garland pencils from Lew Manufacturing of Rhode Island for Apollo and Skylab use. A piece of Velcro was added to the barrel so the pencil could be fixed to the spacecraft interior instead of drifting around the cabin.

The Smithsonian lists the Apollo 11 Garland at about five inches long and a quarter inch in diameter: a compact tool suited to checklists, flight plans, and restrained equipment.

Astronauts used these pencils for practical work rather than ceremony.

They wrote notes and made alterations to flight plans.

That detail matters because Apollo paperwork was not static. Mission crews had procedures, checklists, charts, and plans that sometimes needed to be amended during flight. A pencil remained useful precisely because it could make an immediate mark without batteries, ink flow, or complicated hardware.

The Fisher Space Pen entered this environment in the late 1960s.

Paul Fisher had already been developing a pressurized ballpoint cartridge through his own company. NASA did not pay him millions to invent it. Fisher created the technology privately and submitted the resulting AG7 pen for testing.

NASA tested the pen under demanding conditions. The pressurized cartridge used nitrogen to push the ink toward the ball, so the pen did not depend on gravity. The ink was formulated to remain thick until friction at the rotating ball liquefied it enough to write.

Apollo 7 became the first NASA mission to carry the Fisher Space Pen in 1968.

NASA later adopted it broadly, and Soviet cosmonauts began using Fisher pens as well. That last fact alone breaks the familiar myth. The real choice was not “expensive American pen versus sensible Soviet pencil.” Both space programs used pencils, and both eventually used pressurized pens.

Pencils did not disappear instantly.

Apollo-era collections show that mechanical pencils and Space Pens overlapped. The transition was practical rather than theatrical. NASA was replacing a tool that worked but carried small debris risks with one that could write in microgravity without producing graphite fragments.

For collectors, space-program pencils are fascinating because ordinary design features suddenly acquire aerospace reasons.

A cord is not decorative.

Velcro is not a convenience feature.

A short metal barrel is not merely stylish.

Each modification helps solve the problem of using a tiny hand tool inside a spacecraft where nothing simply stays on the table.

The Garland 35-P is especially interesting because it looks almost too ordinary for Apollo 11. There is no futuristic shape and no dramatic mechanism. It is a small chrome mechanical pencil with a twist advance and a Velcro patch.

That simplicity is exactly what makes it historically valuable.

The pencil reminds us that spaceflight depended not only on rockets, computers, and spacesuits but also on thousands of modest objects that had to work reliably in an environment for which they were never originally designed.

The Space Pen eventually became the famous object.

The pencils came first.
