One. Shepard flew into space twice: Mercury 3, America's first manned space mission, and Apollo 14, the third moon landing. Mercury 3 was a sub-orbital flight lasting 15 minutes. Apollo 14 made one full orbit of the earth before TLI (trans-lunar injection), the refiring of the third stage rocket, that send the CSM (command and service modules) to the moon. TLI occurred halfway through what would have been the second orbit.
