The reason not to use pencils in Space wasn't that Pencil are inflamable, the main reason was the graphit dust produced by Pencils, which because of the lack of gravity, enter floating in the electronic, causing short circuits as main risk.
Besides that, NASA wasn't the one that funded the research behind the pen, they bought the completed pens. The expenses for the research were funded by Fisher
I’ve owned a fair few Fisher Space Pens throughout the years. It’s an interesting bit of space memorabilia that’s functional and affordable. It’s an impressive bit of engineering.
As a space nerd, I love the pen. As a pen guy…. There’s better options. The cartridge just doesn’t write as smooth as I like, nor is it a really bold, saturated line. For daily actual writing use, I use a Lamy Safari rollerball or a Pilot B2P.
I got big into pens for a bit before settling on my edc one-size-fits-most pen. During my travels, I saw that the Fisher Space pens are still highly regarded as great writers even for us grounded folk. Yeah, there's better, but for the size and build quality they're great options. I went with the Ti Arto by Big Idea Design instead. Just so I could use basically any pen cartridges (except cheap bic roller ball).
Huh, the Arto used to be 70usd. I'd say not worth anymore. I got the black one and the paint has already chipped plus the clip is not titanium unless you buy an expensive "premium" clip.
