Space Pen

While scanning through TV channels, I got hooked at Discovery Channel’s feature on how carpets are made and even recycled. After the episode, they featured another topic and this time it was about the Fisher Space Pen.

What’s interesting about the Fisher Space Pen is that it can write in zero gravity, upside down, underwater, over wet and greasy paper, at any angle, and in extreme temperature ranges. And the program demonstrated that indeed the space pen really works upside down and even underwater!

Way back when astronauts where being sent to outer space, they discovered that a normal pen won’t work because of the lack of gravity. And Paul Fisher was just in time for his invention.

While finding an image of the pen online, I stumbled upon a blog that shows that even after 10 years, the Fisher Space Pen still works. What’s special about this pen is that the ink cartridge was pressurized with nitrogen so that it didn’t rely on gravity to make it work.The ball point is also made of a special material normally used in making bullets, making it very sturdy. I would love to get one of these pens if given the chance! 🙂


  1. Some space freaks will certainly like this pen. What use is a gravity pen when there is gravity anywhere on earth? Lol.

    Ok. These features are worth considering: write underwater, over wet and greasy paper, at any angle, and in extreme temperature ranges. Wow..US$50 per pen. One would think that these things would be cheaper by now, eh, Doi? 🙂

    Wishing you a happy day,


  2. if you want to write in zero gravity, why not just use a pencil.

    Lou’s last blog post..I just came back from field camp and Mas Selamat got captured.

  3. i guess they wanted to use something permanent to write on.. the russians used pencil. but the americans wants to spend more… 😆

  4. boy you people are dumb says

    you can’t use a pencil because if even a tiny chip of graphite went floating in space and got between a couple of electrical contacts all hell could break loose. Before fisher space pens they used a crayon type marker, the line about the pencil was a joke that a Vegas guy was using, it’s not reality.
