So-called 'space pens' use ingenious refill technology to enable them to write in adverse conditions - particularly in zero gravity, but also in a range of earthbound conditions that cause problems for ordinary pens. Take a look at our range of pressurised 'space pens' below, or read on...
The story of pressurised pens starts with Paul Fisher, who invented a pen refill that was able to write in zero gravity and who then persuaded NASA to buy the Fisher Space Pen for space missions. The urban myth that NASA spent millions developing the space pen, while the Russians simply used a pencil is sadly not true.
