Space pen is a ballpoint pen invented by Paul C. Fisher

Answer 2

in space there is no gravity which will pull the pen on the paper on anything and on moon there is no friction which will create friction between the pen and the surface on which it is been used and the writings of the pen will not be visible so it is not possible to write with pen space
