Apollo Lunar Module the "Aquarius" and the Command Module "Odyssey". The development and construction of the lunar module is dramatized in the miniseries "From the Earth to the Moon" episode entitled "Spider". This is in reference to LM-3, used on Apollo 9, which the crew named "Spider" after its spidery appearance. The unused LM-13 stood in during the teleplay to depict LM-3 and LM-5, "Eagle", used by Apollo 11. Apollo Lunar Module The Apollo Lunar Module, or simply lunar module (LM, pronounced "Lem"), originally designated the lunar excursion module (LEM), was the spacecraft which was flown to and landed on the Moon. The
Apollo Lunar Module the Moon via Lunar Orbit Rendezvous (LOR) instead of the direct ascent or Earth Orbit Rendezvous (EOR) methods. Both direct ascent and EOR would have involved landing a much heavier, complete Apollo spacecraft on the Moon. Once the decision had been made to proceed using LOR, it became necessary to produce a separate craft capable of reaching the lunar surface and ascending back to lunar orbit. In July 1962, eleven firms were invited to submit proposals for the LEM. Nine companies responded in September, answering 20 specific questions posed by the NASA RFP in a 60-page limited technical proposal. Grumman
