The spacecraft that took astronauts to the moon was the Apollo Lunar Module (LM), also known as the "Lunar Excursion Module". It was a two-stage spacecraft that was designed to land on the moon and return its crew back to lunar orbit.

While the Apollo LM is the most recognizable part, it was actually a part of the larger Apollo Command/Service Module (CSM) spacecraft. The CSM served as the astronauts' transportation to the moon and back, providing life support, propulsion, and a command center.

So, to be completely accurate, the astronauts traveled to the moon in the Apollo CSM and then landed on the moon in the Apollo LM.
