The term SPACE CRAFT can be broken down into two parts: the acronym LEM, which stands for Lunar Excursion Module, and the word 'CRAFT'. The Lunar Excursion Module was a spacecraft built by the United States during the Apollo program in the 1960s and 1970s. It was designed to transport astronauts from the Command Module to the surface of the moon and back. The CRAFT was the first manned vehicle to land on the moon and was used in all six successful Apollo missions.
