Abstract : During the second flight of Stratoscope II, the infrared spectrum of the Moon (Mare Tranquilitatis) was traced from 0.8 microns to 3.0 microns at a balloon altitude of 83500 feet. The intensity of the reflected solar radiation was found to decrease from 0.8 microns to about 2.5 microns where the Moon's thermal emission becomes significant. The computed radiance factor (phase angle = 53 degrees) increases smoothly from about 4 per cent at 1 micron to about 12 per cent at 2.3 microns, indicating that the lunar albedo is substantially higher in the infrared than in the visual.
