 The primary distinction between the later Apollo missions and Lunex was the orbital rendezvous maneuver.The Lunex vehicle, composed of a landing module and a lifting body return/re-entry module, would land the entire vehicle and all astronauts on the surface, whereas the final Apollo mission involved a separate ascent module leaving the command module and service module connected in lunar orbit with a single astronaut.The original plan for Apollo was for direct ascent, similar to Lunex.
