NASA Craft refers to the three spacecrafts developed by the National Aeronautics and Space Administration (NASA). The first is the Space SHUTTLE, a reusable spacecraft used for transporting astronauts and cargo into space. The second is the Lunar Excursion Module (LEM), a spacecraft designed to land on the moon and return to Earth. The third is the Lunar Excursion Module Simulator (LEMS), a simulator used to train astronauts for the Apollo missions. All three of these spacecrafts were integral to the success of the Apollo missions and the exploration of space.
