Designed by Grumman's brilliant Tom Kelly, the Apollo Lunar Excursion Module (or "LEM" for short) was a triumph of purpose-built engineering. In the six years 1962-1968 between drawing board and first flight, a myriad of challenges were overcome related to weight, reliability and safety. The final design, designated the Lunar Module or "LM," boasted tiny windows instead of large portholes, four legs instead of five and most famously had no seats instead relying on the astronauts' legs to cushion a lunar landing. Ten LMs made it into space including three flown in development and test missions, and six which landed on the Moon. A seventh famously saved the crew of Apollo 13 when that mission's Command Module suffered a catastrophic malfunction. Originally created for NASA by Grumman in 1964, this LEM Familiarization Manual provides an operational description of all subsystems and major components of the lunar lander. It includes sections about the LEM mission, spacecraft structure, operational subsystems, prelaunch operations, and ground support equipment.

Originally created for NASA in 1969 by prime contractor Grumman, this Lunar Module Vehicle Familiarization Manual was mandatory reading for Apollo astronauts, contractors and NASA support staff. This version of the manual describes the so-called ELM, or Extended Lunar Modules designed for the "J"class missions Apollo 15-17 and the never-flown Apollo 18 and 19. The ELM came about as part of NASA's efforts to enhance the scientific study of the Moon and its geology. To do that, longer surface stays would be needed. To make it possible, LM 10 to LM 14 received various modifications intended to increase their payloads, and allow them to return larger samples to Earth. Over forty major changes were planned, including enlarging the fuel and oxidizer tanks on both the ascent and descent stages, extension of the descent engine nozzle to improve its efficiency and allow it to deliver more power, and added capacity of oxygen and water. Some changes, such as adding solar cells and affiliated batteries to allow surface stays of up to 72 hours, proved too difficult given the program's schedule. In the end, the maximum duration of stays on the Moon would be limited to 54 hours. The extended LM weighed up to 36,500 pounds compared to 32,000 for earlier versions. The ELM's larger payload capacity enabled it to carry the 463 pound (mass) Lunar Roving Vehicle and other scientific equipment. The LRV greatly enhanced the astronauts' range and ability to retrieve samples. It's never been easy to find a copy of this text because copies were never made available to the general public -- until now. This reprint features all the original text and diagrams. It's a wonderful reference for the space flight fan, docent or engineering buff or for anyone else who ever wondered, "How'd they do that "

Not illustrated. 1938 edition. Excerpt: ...the statute books clear of obsolete and unimportant and useless acts. TO THINK ABOUT AND DISCUSS What examples of careless law breaking have you seen in your neighborhood? What loss did it cost in life, or limb, or in money values? Can the destruction of other people's property by over-enthusiastic students, in celebrating a football victory, for instance, be justified or condoned? On what basis? Are many automobile accidents due to the non-observance of traffic laws and regulations? What has been your observation? The community spends considerable money in the installation and maintenance of automobile traffic signals at street crossings. Why are there so many accidents at these particular crossings, in spite of the special precautions which have been taken? FOR FURTHER READING Building Citizenship, R. O.

In this review of major extension activities in the past thirty-four years, we find an impressive record from the point of variety and scope of the service of the university to the state. In truth the extension services have done much to make the University of North Carolina at Chapel Hill the "University of the People."
