Ink relies on gravity to make it flow down and out of the pen. When you are in space, there is no constant gravity so the ink doesn't flow. A pencil doesn't have that problem, it works regardless of gravity. Just put pencil on the page and push it around and the graphite tip will leave a mark.

What are some tools that astronauts use to explore space?
Astronauts use tools such as space suits equipped with life support systems, robotic arms for handling objects outside the spacecraft, and scientific instruments like spectrometers and telescopes to explore space. They also rely on spacecraft like the International Space Station and rovers to aid in their exploration.
Do astronauts sleep in space?
Yes, they do.
How do astronauts get oxygen into space?
They carry it with them on board.
What is the time astronauts use while in the space since they travel from so fast between time zones?
Houston time.
Can a pencil write in outer space?
A traditional ballpoint or fountain pen relies upon gravity; try writing on a piece of paper with the pen upside down for a while, and it will cease to function. Similarly, if you attempt to use a conventional pen in a low/zero gravity environment there is nothing to direct the flow of ink 'downwards' through the nib or ballpoint, so the ink will eventually stop flowing. The lack of gravity is a greater concern for astronauts who wish to keep a diary than the hostile environment of space. Extreme temperatures and the vacuum of space are not the main issues likely to affect an astronaut floating around in his insulated, oxygenated tin can. If they did become issues, it is unlikely that he/she would stop to write about it anyway, as imminent death has presumably higher priority than ink flow. However, that didn't stop NASA courting some controversy over the use of some very expensive pencil holders designed for use by suited astronauts with bulky gloves. The issue of a space pen has been the subject of legends that go something like this: Back in the 60's, as the space race was gearing up, NASA was faced with developing a method of writing in zero gravity and/or the vacuum of space; the 'astronaut pen' was developed at a final cost of about $1,500,000. Russia's space agency was faced with precisely the same problem; they used pencils. Of course, this is completely false, and probably attributable to some clever marketing by the Fisher Space Pen Company. Pressurised ink cartridges are used in the Fisher 'Space Pen'. It is claimed that it can write in zero gravity, under water, upon wet or greasy surfaces, and at extreme temperatures... so it's exactly what you need should you have to write an SOS note during the explosive decompression of your space capsule!
Why do astronauts use space pen?
astronauts use space pen because as there is 0gravity in space ink will not fall on the paper
What do astronauts use?
a space belt
Why can't a pencil be used in outer space?
A pencil can be used in outer space, but traditional wooden pencils are not ideal for writing in space due to the lack of gravity. The graphite tip can break off and float around, potentially getting in astronauts' eyes or equipment. Instead, astronauts often use special mechanical pencils or pens that work in microgravity.
What is space spacecraft?
A rocket plane that astronauts use to travel to space.
How do astronauts get oxygen in space?
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
What do astronauts use to stay cool in space?
ac
What do astronauts use to go to the moon?
Space Ships
How do astronauts navigate in space?
They read the same way as they do on earth.
How do we explore space from earth?
We use space probes, and send astronauts... etc.
What does astronauts use?
Astronauts use space shuttles( trasport people and equipment), Space probes (robotic exploration, Spacecrafts (trasport crew, equipment, and other technologies)
What technology does astronauts use?
Astronauts use space shuttles( trasport people and equipment), Space probes (robotic exploration, Spacecrafts (trasport crew, equipment, and other technologies)
How do astronauts communicate outside the space shuttle?
They use radios built in their space suits.
