lunar-orbit rendezvous (LOR)
As a means of reaching the Moon's surface, it has the advantage that the lunar landing vehicle can be designed specifically for this task and be of low mass since all the equipment and supplies for the return to Earth can be left in lunar orbit. Against this, however, must be set the difficulty and danger of having to maneuver and dock two vehicles in lunar orbit. Despite this drawback, LOR was the technique eventually chosen to convey astronauts to and from the Moon in the Apollo program. The person primarily responsible for urging this approach over two other flight plans that were being considered, the so-called direct ascent and Earth-otbit rendezvous, was John C. Houbolt of the Langley Research Center early in 1962.
