FOREWORD From July 19 through July 31, 1965, the National Aeronautics and Space Administration conducted a Lunar Exploration and Science Conference at the Lawrence High School in Falmouth, Massachusetts. The conference was held immediately after completion of the Space Science Summer Study conducted at Woods Hole, Massachusetts, for NASA by the National Academy of Sciences. The Lunar Conference was under the auspices of the Manned Space Science Coordinating Committee appointed by Homer E. Newell, the Associate Admin- istrator for the Office of Space Science and Applications (OSSA). This Coordinating Committee was established to advise Willis B. Foster, Director of the Manned Space Science Program of the Office of Space Science and Applications, and consists of one member from each of the Subcommittees of the Space Science Steering Committee and the Chairmen of seven discipline-oriented Working Groups. The Chairman of the Coordinating Committee is Richard J. Allenby, Deputy Director, Manned Space Science Programs, who also acted as conference chairman. The conference secretary was Jay Holmes, Field Center Development, Office of Manned Space Flight. The function of the Working Groups and the Coordinating Committee is to advise NASA on a sound, feasible, scientific exploration pro- gram for the Moon. The Chairmen and Secretaries of the Working Groups of the Manned Space Science Coordinating Committee are as follows: GEODESY/CARTOGRAPHY: Chairman, Hellmut Sehmid, U.S. Coast and Geodetic Survey, Rockville, Maryland; secretary, James Sasser, Manned Spacecraft Center, NASA, Houston, Texas. GEOLOGY: Chairman, Eugene M. Shoemaker, U.S. Geological Survey, Flagstaff, Arizona; secretary, Donald Beattie, Advanced Manned Missions Program Office, Office of Manned Space Flight, NASA Headquarters. 2 CONFERENCE ON LUNAR EXPLORATION AND SCIENCE GEOPHYSICS: Chairman, Frank Press, Massachusetts Institute of Technology, Cambridge, Massachusetts; secretary, Edward Davin, Manned Space Science Programs, Office of Space Science and Applications, NASA Headquarters. BIOSCIENCE: Chairman, Melvin Calvin, University of California, Berkeley, California; secretary, Siegfried Gerathewohl, Manned Space Science Programs, Office of Space Science and Applications, NASA Headquarters. GEOCHEMISTRY: Chairman, James Arnold, Scripps Oceano- graphic Institute, La Jolla, California; secretary, Paul Lowman, Goddard Space Flight Center, NASA, Greenbelt, Maryland. PARTICLES AND FIELDS: Chairman, Wilmot Hess, Goddard Space Flight Center, NASA, Greenbelt, Maryland; secretary, Jacob Trombka, Manned
