The challenge of writing in space

Writing in zero gravity isn't as simple as it is on Earth. Ink won't flow down, and pencils pose fire hazards. So, how do astronauts take notes? Image source: generated by AI tool

Why pencils weren’t the best solution

Early space missions used pencils, but broken graphite tips and shavings could be hazardous in a spacecraft. A better solution was needed. Image source: generated by AI tool

The problem with ordinary pens

Traditional ballpoint pens rely on gravity to push ink to the tip. In zero gravity, they simply don’t work. Image source: generated by AI tool

Enter the Fisher Space Pen

Invented by Paul C. Fisher in 1965, the Space Pen used pressurized ink to work in zero gravity. Image source: By Unknown - Original publication: This photo was most likely utilized for the back of packaging (sans the background) during his lifetime, particularly during his last 10-20 years.Immed
