The only difference between space pens and any other kind of pen is that space pens work in any position in which you hold them, whereas other pens need gravity to make the ink flow to the tip, so that they will dry up if you try to write with them in the wrong position.
The pressure in the bulb of the fountain pen is 1 atmosphere as it is loaded with ink on the surface of earth. As we travel away from earth the pressure drops, so in the space where pressure is subatmospheric, the ink flows out,from inside out as favoured by the pressure gradient. Padmanbahan Raghu, INDIA
Yes, astronauts can see the curvature of the Earth from space.
A sentence using the word earth and space science is this.
A space satellite is any man-made object that orbits Earth or another celestial body, while an Earth satellite specifically orbits Earth. Additionally, space satellites can include artificial satellites launched into space for various purposes, while Earth satellites can refer to natural objects like the Moon that orbit our planet.
Some space missions that have investigated Earth include the Hubble Space Telescope, the Terra satellite, and the International Space Station. These missions have provided valuable data on Earth's atmosphere, climate, land surface, and oceans.
They use space pens for writing notes under water or for space to write any kind of notes on a special pad.
Fountain pens rely on gravity to draw ink towards the nib, which wouldn't work in the microgravity environment of space. Additionally, ink cartridges in fountain pens can leak or explode due to pressure changes in space, making them unsuitable for use in that environment. Ballpoint pens or specialized space pens are commonly used instead.
Pretty much the same way you use pens anywhere else. The "Fisher Space Pen", developed by private industry for NASA, uses a pressurized ink cartridge to push the ink through the barrel to the ball point. This not only enables the user to write in zero-G in space, but also write UPSIDE DOWN here on Earth!
Pencils are often used in space because most pens rely on gravity to work and are therefore useless in orbit.
Yes, pens can work in space. In a zero-gravity environment, pens use a pressurized ink cartridge and a special mechanism to push the ink out onto the paper. This allows the pen to write without relying on gravity to pull the ink down.
due to zero gravity of ink
the history of pens is the weirdest thing on earth but i do not know. that is what I am trying to figure out.
Many people use pens
Lie down and write with a ball point pen upside down. after a while the pen wont work because it needs the ink to fall down to the ball point. there is no gravity in space there fore the ink will just float it wont fall Edit: why not use a pencil?
We use space probes, and send astronauts... etc.
Optical and Radio telescopes.
Yes
