Laser beams, computers, and satellites were being used by NASA to gather data over a five-year span for the National Oceanic and Atmospheric Administration and the U.S. Geological Survey to help predict earthquakes along California's 965-km (600-mi) San Andreas fault. Lasers at precise locations on either side of the fault were beamed to satellites Explorer 27 (launched April 29, 1965), Explorer 29 (Geos 1, launched Nov. 6, 1965), and Explorer 36 (Geos 2, launched Jan. 11, 1968) and bounced off tiny mirrors. Reflections were recorded by computers and sent to Goddard Space Flight Center, where analysis gave measurements of the slightest variation at a laser's base. A mathematical model would eventually be constructed to assist in predicting quake behavior. (GSFC proj off; GSFC PAO; LA Her-Exam, 3/4/73)
NASA's Lunar Exploration Office in the Apollo/ASTP Program Office was reassigned from the Office of Manned Space Flight (OMSF) to the Office of Space Science (OSS) under the title Lunar Programs Office. The office would be responsible for formulation of future lunar programs, continued operation of lunar science stations, and analysis and synthesis of lunar data. Capt. William T. O'Bryant 'would continue as Director and Dr. Noel W. Hinners as Deputy Director and Chief Scientist. (NASA Hq WB, 3/12/73)
