Why did NASA spend millions developing a pen that would work in space when a pencil is just as good? ​

Answer»

Because pens can't function in zero gravityExplanation:NASA scientists realized that pens could not function in zero gravity. They therefore spent years and millions of taxpayer dollars developing a ballpoint pen that could put ink to paper without needing gravitational force to pull on the fluid.PENCILS may not have been the best choice anyway. The tips could flake or break off, drifting in microgravity where they might harm an ASTRONAUT or EQUIPMENT. And pencils are flammable—a characteristic NASA wanted to avoid in onboard objects after the APOLLO 1 fire.
