I'm assuming you've found the difference between Harm and Damage? Page 35 of the preview explains it.
As far as I can tell, there are no rules for what happens when Damage is dealt to individual people (such as a ship firing Lasers to hit one of the characters standing on the ground). I've made a rule in my game that weapons such as these deal Harm equal to Damage+2. However, I also always assume that these weapons don't score direct hits against an individual, since a person is so much smaller than a ship. If there came a situation where the fiction called for the character to suffer a direct hit, I'd say the character dies, as in Death in the Void on page 37 of the preview.
