A REMARKABLE DIAGRAM OF THE ONLY CREWED VEHICLE TO LAND ANYWHERE BEYOND EARTH The Lunar Module was built for the US Apollo program by Grumman, with the aim of carrying a crew of two from lunar orbit to the surface of the moon, and safely back. After completing its mission, the LM was then discarded. Interestingly, the LM was capable of operation only in outer space. Aerodynamically and structurally, it could not fly through Earth's atmosphere. It was also the first manned spacecraft to operate exclusively in the airless vacuum of space.

AN INCREDIBLE PIECE OF DESIGN HISTORY
