post #20: When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity. To combat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down, underwater, on almost any surface, and at temperatures ranging from below freezing to 300 degrees Celsius.
The Russians used a pencil.
post 21 # it seems using a pencil was not enough to send a man to moon for Russians.
Why don't you kindly remind everyone who sent the first rocket into space, or the first human into space, perhaps who had the first satelite or even the first space station. And all of the world fanciest pens didn't help the US built a comparable rocket engine to the RD-180 so they just perchased it from Russia and put it in their rockets.
In any case stop polluting this forum, and you're Turkish you have no right critisizing anyones technology since you can do very little without forign help.
