NASA designed the MET lunar hand cart to help with problems such as the Apollo 12 astronauts had in carrying hand tools, sample boxes and bags, a stereo camera, and other equipment on the lunar surface. The MET would extend lunar surface activities to a greater distance from the lunar module prior to availability of the Apollo Lunar Rover vehicle. It was planned to use the MET on Apollo 13, 14, and 15. But the Apollo 13 landing was aborted, and the original Apollo 15 H class mission was cancelled. So the MET was only used on Apollo 14.

NASA was considering incorporation of a mobile equipment transporter on LM-8, LM-9, and LM-10, to help with problems such as the Apollo 12 astronauts had in carrying hand tools, sample boxes and bags, a stereo camera, and other equipment on the lunar surface. The MET also could extend lunar surface activities to a greater distance from the lunar module. A prototype MET and training hardware were being fabricated and were expected to be available in late December.
