X-15 No. 3 was flown to 3,580 mph (mach 5.11) and 254,200-ft. altitude by NASA pilot William H. Dana for altitude buildup, micrometeoroid collection, measurements of total solar flux and broadband light distribution by JPL spectroradiometer, and radiometer measurements of ultraviolet exhaust plume characteristics. ‘‘(X-15 Proj. Off.; FRC Release; JPL Release 408)’’
LUNA XI, U.S.S.R.’s second lunar orbiting satellite, launched Aug. 24, was continuing to orbit moon and had completed 1,410 revolutions, Tass announced. All equipment was functioning normally. ‘‘(Tass, 9/ 14/66)’’
U.S.S.R. astronomers had scanned the Milky Way in six-centimeter wavelength for first time, using Pulkovo Observatory’s huge radiotelescope and parabolic antenna. Observations did not confirm current theory that radio emanations were primarily linked with radio glow of “hot gas” (ionized hydrogen) in our galaxy, but showed that “even in these wave-lengths a considerable role is played by the emanation of fast electrons moving in magnetic fields at speeds close to that of light.” Simultaneously, Pulkovo astronomers conducted detailed study of 80 other clouds of ionized hydrogen to “help determine more exactly the physical conditions which exist in the most interesting parts of the Milky Way and their relationship with the continuous radio emanation of our galaxy as a whole.” ‘‘(Tass, 9/14/66)’’
