you seem to like these vague puzzles with multiple potential answers...
first guess: it is a space ship. the rock in a asteroid. the rip in the spacesuit causes depresurization when he goes out of the airlock and he explodes in a rather "gory" fashon.
second guess: it is a regular ship. the rock is a rock. the man's pants get caught on either the edge of the sip, or on the door and he gets squished beween the ship and the rock.
for your next one can you try something a bit more logic based and less "looking at the problem through the eyes of the poster"?
i'd suggest something like the 3 switches/1 lightbulb in a closed room problem. if people don't already know that one I can post it.
