Should Astronauts Choose Pencils With Hard Or Soft Lead For Making Notes In Space Explain

Astronauts should choose pencils with a soft lead because it doesn’t as much force to mark on paper. Theoretically speaking, the magnitude of the force could push an astronaut away from the piece of paper in space; therefore, a soft lead is easier to use in space.

The astronauts used these writing utensils in space to write mission reports, conduct post-mission analysis, or record anomalies on fireproof paper. The pencils were generally safe to use, but they came at a huge cost: NASA paid $4,382.50 for 34 mechanical pencils from Tycam Engineering Manufacturing in Houston, or $128.89 per pencil.

NASA wanted to avoid pencils because the lead could easily break off and float away, creating a hazard to astronauts and sensitive electronics on the spacecraft. In fact, a pencil is such an impractical alternative in space that cosmonauts also have been using Space Pens since 1969. Did it cost taxpayers millions? Nope.

To understand why NASA was so keen on a workable space pen, you have to understand that the pencil is not suited for space travel. The problem is that they have a habit of breaking, shattering, and leaving graphite dust behind.

Can astronauts use pencil in space?

The pencil wasn’t an ideal choice for writing in space because its tip could flake and break off, drifting in microgravity with the potential to harm an astronaut or an equipment. Apart from this, pencils are flammable, and NASA wanted to avoid anything flammable aboard a spacecraft.

Do pens work in space?

Ordinary ball point pens did not work in space because the ink would not flow by gravity to the ball and the pen leaked if pressure was created in the ink reservoir (here).

Do astronauts use Space Pens?

NASA astronaut Walter Cunningham writes with a Fisher Space Pen during the flight of Apollo 7, the first crewed Apollo flight and the Space Pen’s first trip to space. The pens have been used on every NASA human spaceflight mission since.

Why did NASA stop using pencils?

Pencils may not have been the best choice anyway. The tips flaked and broke off, drifting in microgravity 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.

Why dont astronauts use pencils in space?

NASA wanted an alternative to pencils because the lead could easily break off and float away, creating a hazard to astronauts and sensitive electronics on the spacecraft. Cosmonauts also have been using Space Pens since 1969.

Do astronauts use pencils?

But, alas, it is just a myth. Originally, NASA astronauts, like the Soviet cosmonauts, used pencils, according to NASA historians. In fact, NASA ordered 34 mechanical pencils from Houston’s Tycam Engineering Manufacturing, Inc., in 1965.

Why pens are not used in space?

Ordinary ball point pens did not work in space because the ink would not flow by gravity to the ball and the pen leaked if pressure was created in the ink reservoir (here). NASA used to use pencils, and in 1965 there was controversy over how much they spent on them.

Are space pens worth it?

I’ve grown to love the Fisher Bullet Space Pen, after a few days of practice and regular use. The pen writes very smoothly and without the stickiness of a standard cheap ballpoint pen. The pen leaves a deep black line on the page, without having to excerpt so much pressure that writing becomes uncomfortable.

So the maximum acceleration is amax =29,420/12,000=2.45 m/s 2 =5.5 mph/s. This means that if you speed up to 5.5 mph in one second, the rope will almost break. Of course, there will be friction and so to be safe I would recommend a factor of roughly two, an acceleration of about 3 mph/s would probably be safe.
