Why pencils cannot be used in space

When the first principal of the movie gathered the students in the garden, he said that in my hand it was a space pen, it was a multi-million dollar pen for the use of astronauts.

Which is used for writing in space. Then Aamir Khan said that if you use a pencil without using this pen, everything will be solved. Ordinary pens in space cannot be used in Micro Gravity or Zero Gravity. Since the Earth has less gravity in space, ordinary Earth columns cannot be used there. So NASA wants such a pen to write in space. Through various experiments, NASA invented a pen called the "Fisher Space Pen" for various manned and outdoor space missions that could be written in space, and it cost millions of dollars to discover this pen.

Currently, the two largest countries in the world, the United States and Russia, use this space fissure pen. This zero gravity paint in space uses pressurized ink cartridges with nitrogen gas. Underwater, above water, wet, oily, plastic, anywhere can be written using this pen in any way. By , both America and Russia were using these pens in space. Pencils have a habit of breaking, shattering, or leaving graphite dust. This would prove to be a serious fire risk in the pressurised, oxygen rich capsule.

For a while, mechanical pencils were favored by NASA; however, these too are dangerous. Stray graphite dust is impossible to gather, highly flammable and conductive—just about the worst thing possible to be floating around in a spacecraft with sensitive electronics that are keeping people alive. Without gravity to allow the graphite to settle, pencil etchings were prone to severe smearing, making them fairly worthless for permanent documentation.

The Russians did use pencils for a brief time, which did not pose the risk to electronics but still suffered from all the other problems, and the paper shrouds used created a lot of flammable waste.

So, the short reason is that astronauts only used pencils when they were waiting for something suitable to be invented. As soon as it was, they switched and never looked back. Even the Russians thought it was a good idea. Another cool thing about the space pen is that it is quoted as being able to write for exactly Plenty enough for a trip to the moon and back.

By Reuters Fact Check. A pen that works in zero gravity, underwater and at extreme temperatures was designed for use in space in the s. Its development was funded by Paul C. It is used by both American and Russian astronauts.
