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.
space satellites are in space and earth satellites are in earth.
It studies the earth and its neighbors in space.
Earth has lots of gravity to pull you back and space does not, space is like a never ending trampoline.
Space probes leave Earth, they do not go toit.
A sentence using the word earth and space science is this.
They use space pens for writing notes under water or for space to write any kind of notes on a special pad.
there are no ballpoint pens in space. But you can use pencils or a fine-liner (that uses capillary suction).
Pencils are often used in space because most pens rely on gravity to work and are therefore useless in orbit.
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.
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!
Many people use pens
We use space probes, and send astronauts... etc.
Optical and Radio telescopes.
Yes
Sounds like a homework question.The mass doesn't change. Only the weight.
black pens are neater and easier to read.
