Ranger 7 was a real spacecraft. The first Ranger missions flew past the moon becuase of miscalculations and a hope that they might enter orbit of the moon, even though they had way to much velocity to do such. Ranger 7 was deliberately pointed AT the moon and successfully impacted, giving a lot of great information for scientists here on earth about the moon and its composition in addition to the close up pictures it returned.
