After serving as a liaison officer of NACA and as a participating member of an Advanced Research Projects Agency panel, Maxime A. Faget reported to Dr. Hugh Dryden on resulting studies and attending recommendations on the subject of manned space flight. He stated that the Advanced Research Projects Agency panel was quite aware that the responsibility for such a program might be placed with the soon-to-be-created civilian space agency, although they recommended program management be placed with the Air Force under executive control of NACA and the Advanced Research Projects Agency. The panel also recommended that the program start immediately even though the specific manager was, as yet, unassigned. Several of the proposals put forth by the panel on the proposed development were rather similar to the subsequent evolvement. The system suggested by the Advanced Research Projects Agency was to be based on the use of the Atlas launch vehicle with the Atlas-Sentry system serving as backup; retrorockets were to be used to initiate the return from orbit; the spacecraft was to be nonlifting, ballistic type, and the crew was to be selected from qualified volunteers in the Army, Navy, and Air Force.

Secretary of the Air Force Eugene M. Zuckert announced that three firms, Douglas Aircraft Company, General Electric Company, and The Martin Company, had received authorization to begin work on space station studies. Zuckert predicted also that the Titan III would be test-flown that summer and would launch the Manned Orbiting Laboratory sometime in 1967 or 1968.

OGO 6 was a large observatory instrumented with 26 experiments designed to study the various interrelationships between, and latitudinal distributions of, high-altitude atmospheric parameters during a period of increased solar activity. On June 22, 1969, the spacecraft potential dropped significantly during sunlight operation and remained so during subsequent sunlight operation. This unexplained shift affected seven experiments which made measurements dependent upon knowledge of the spacecraft plasma sheath. During October 1969, a string of solar cells failed, but the only effect of the decreased power was to cause two experiments to change their mode of operation. Also during October 1969, a combination of manual and automatic attitude control was initiated, which extended the control gas lifetime of the attitude control system. In August 1970, tape recorder (TR) no. 1 operation degraded, so all recorded data were subsequently taken with TR no. 2. By September 1970, power and equipment degradation left 14 experiments operating normally, 3 partially, and 9 off. From October 14, 1970, TR no. 2 was used only on Wednesdays (world days) to conserve power and extend TR operation. In June 1971, the number of 'on' experiments decreased from 13 to 7, and on June 28, 1971, the spacecraft was placed in a spin-stabilized mode about the yaw (Z) axis and turned off due to difficulties with spacecraft power. OGO 6 was turned on again from October 10, 1971, through March 1972, for operation of experiment 25 by The Radio Research Laboratory, Japan. References: 1 , 2 , 5 , 6 .
