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 command and service module separate lunar module, and thus had no provisions for docking with another spacecraft. This, plus other required design changes, led to the decision to design two versions of the CSM: Block I was to be used for uncrewed missions and a single crewed Earth orbit flight (Apollo 1), while the more advanced Block II was designed for use with the lunar module. The Apollo 1 flight was cancelled after a cabin fire killed the crew and destroyed their command module during a launch rehearsal test. Corrections of the problems which caused the fire were applied to the Block II spacecraft,
