In 1960’s During the space race between Russia and NASA
NASA scientists realized that pens could not function in space.
They needed to find an another way for the astronauts to write things in space. So they spent years and millions of taxpayer dollars to develop a pen that could put ink to paper without gravity.
But Russian scientists, simply handed pencils to their Astronauts
The whole world laughed at NASA, social media till now trolling ” NASA Spent Millions to Develop a Pen that Would Write in Space, whereas the Soviet Cosmonauts Used a Pencil “
It’s just a myth in Fact NASA ordered 34 mechanical pencils from Houston’s Tycam Engineering Manufacturing, Inc., in 1965.
They paid $4,382.50 or $128.89 per pencil. When these prices became public, there was an outcry and NASA scrambled to find something cheaper for the astronauts to use.
Pencils may not have been the best choice anyway.
Their tips are made up of graphite,The tips flaked and broke off, drifting in microgravity and they can conduct electricity too, where they could potentially harm an astronaut or equipment.
And pencils are flammable–a quality NASA wanted to avoid in onboard objects after the Apollo 1 fire.
Paul C. Fisher and his company, the Fisher Pen Company, reportedly invested $1 million to create what is now commonly known as the space pen.
None of this investment money came from NASA’s coffers–the agency only became involved after the pen was dreamed into existence.
In 1965 Fisher patented a pen that could write upside-down, in frigid or roasting conditions (down to minus 50 degrees Fahrenheit or up to 400 degrees F), and even underwater or in other liquids. If too hot, though, the ink turned green instead of its normal blue.
The same year fisher offered NASA To use AG-7 The Antigravity space pen, After testing the pen NASA decided to use in Space pen in 1967
How Space pen works?
Fisher’s pen does not rely on gravity to get the ink flowing. The cartridge is instead pressurized with nitrogen at 35 pounds per square inch.
This pressure pushes the ink toward the tungsten carbide ball at the pen’s tip.
The ink is different for space pens unlike ballpoint pens space pen ink is not in liquid form, a gel like solid ink
