Answer:
Friction exists in space, just that not in the most familiar cases. Walking or rolling are not normally possible without gravity pushing both bodies in contact with a normal force. However the normal force does not have to be only gravity, it could be caused by pressure or some other force (thrusters, magnetism etc.

Answer:
Friction exists even without gravity. Because the only thing you need to create friction is force no matter from where it is applied.
Explanation:
If you rub your hands in space heat it produced which indicates the presence of friction ( GRAVITY DOESN'T EXISTS IN SPACE )
