What would happen if I walked on Moon without my spacesuit?
That sounds really dangerous. What about if I wore a spacesuit with no helmet?
Wearing a spacesuit without a helmet on the moon would still be lethal, as the lack of atmosphere would cause the oxygen and air in your body to boil away into space. You would also be exposed to harmful radiation and extreme temperatures. It's always important to wear full protective gear in space.
