| I think the idea behind using a pen is that pencil points break off. This leaves a little conductive piece of graphite and clay floating around. Also, sharpening a pencil is messy with the effect of gravity, in freefall NASA would need a multimillion dollar pencil sharpener that costs an addition $10000 to lift into orbit. Even if mechanical pencils were used, you'd still have the broken points (and probably entire pencil leads floating around). | |
