The thixotropicink in the hermetically sealed and pressurized reservoir is able to write for three times longer than a standard ballpoint pen. The pen can write at altitudes up to 12,500 feet (3800 m). The ink is forced out by compressed nitrogen at a pressure of nearly 35 psi (240 kPa).
Correspondingly, why can't you use a pencil in space?
Russian sensibility. It's also entirely false. 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.
Beside above, how does Fisher Space Pen work? The secret to the space pen is in the cartridge. It is a hermetically sealed tube containing thixotropic ink, pressurized nitrogen gas, and a tungsten carbide ballpoint tip. He developed a thixotropic ink that is a gel at rest, but turns into a liquid under pressure. Sort of like toothpaste.
Considering this, why did NASA spend millions a pen?
During the height of the space race in the 1960s, legend has it, NASA scientists realized that pens could not function in zero gravity. They therefore spent years and millions of taxpayer dollars developing a ballpoint pen that could put ink to paper without needing gravitational force to pull on the fluid.
Do ballpoint pens work in space?
A ballpoint pen will work just fine in outer space. However, a normal ballpoint pen won't work so well in the absence of appreciable gravity for the same reason that a normal ballpoint pen won't write upside down the ink doesn't flow onto the ball in enough quantity for the pen to work.

Fire is a different beast in space than it is on the ground. When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don't rise. Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.What can I use I pencil for?
