do pens work in space, or do they have a special type of writing untensil?
also, when the guys are space walking, when they are pushing and pulling on the space station to do what they need to do, does the iss move around?
I don't know if this is an urban myth but, there was some speculation years abo that during the space race NASA spent millions on designing a biro that would work in free fall and that the Russians just used pencils.
My view - score one for the Russians.
Yes they would move the ISS around, but only a tiny tiny bit due to the difference in mass.
