Orbiting Geophysical Observatory 3. All 21 experiments returned good data. At the time, this was the largest experimental complement ever put into orbit. There were 4 cosmic ray instruments (1 of which included a gamma-ray spectrometer), 4 plasma, 2 trapped radiation, 2 magnetic fields, 5 ionosphere, 3 radio/optical, and 1 micrometeoroid detectors. OGO 3 maintained 3-axis stabilization for 46 days. At that point, an attitude controller failed and the spacecraft was put into a spin on 23 July 1966. The spin period varied from 90-125 seconds. By June 1969, data acquisition was limited to 50% of the orbital path. Routine spacecraft operation was discontinued on December 1, 1969, after which only data from Heppner's experiment (Rubidium + Fluxgate magnetometer) was acquired. By March 1971 spacecraft perigee had increased to 16,400 km and the inclination had increased to 75.8 deg. All spacecraft support terminated on February 29, 1972. References: 1 , 2 , 5 , 6 , 278 .
Robert O. Aller, NASA OMSF, told Apollo Program Director Samuel C. Phillips that considerable analysis, planning, and discussion had taken place at MSC on the most effective sequence of Apollo missions following the first manned flight (Apollo 7). The current official assignments included three CSM/LM missions for CSM/LM operations, lunar simulation, and lunar capability. MSC's Flight Operations Directorate (FOD) had offered an alternate approach of that sequence by proposing that the third mission be a lunar-orbit mission rather than a high earth-orbit mission. Aller preferred the FOD proposal, since it would offer considerable operational advantages by conducting a lunar-orbital flight before the lunar landing. He recommended Phillips consider that sequence of missions and that consideration be given to including it as a prime or alternate mission in the Mission Assignments Document. "Identifying it in that document," Aller said, "would initiate the necessary detailed planning." References: 16 .
Robert C. Seamans, Jr., Deputy Administrator of NASA, prepared a memorandum to the file concerning the selection of North American Aviation as the CSM prime contractor. The memorandum, a seven-page document, chronologically reviewed the steps that led to the selection of North American and followed by about a month the statement of NASA Administrator James E. Webb in response to queries from members of the Congress. References: 16 .
