When NASA sent the first person into space we learned an ink pen would not work in zero gravity. The US spent something like $20,000 developing a pen that would work in outer space. The Russians used a pencil.
inside the craft a standard biro works fine, as capliary action will continue to push ink down the tube. infact it may work better than it would on the ground, as when "upside down" it doesn't have gravity to contend with.
meanwhile pencils release tiny bits of graphite, which can get into the electronics and play merry hell with them, apparently.
