A spaceship can travel in a vacuum because it produces thrust. The thrust going on the back the the craft actually pushes on the front of the craft (much like a balloon does when you release the untied end. Since it is in a vacuum, there is no friction to slow the craft down once it is moving.

No, a fly would not be able to fly in a vacuum because it relies on air resistance and pressure to generate lift and maneuver in the air. In a vacuum, there would be no air molecules for the fly to interact with, so it would not be able to fly.
