The far-infrared planetary brightness temperatures of Armstrong, Harper, and Low (1972) are recalibrated to allow for the varying temperature of Mars, using the thermal model of Neugebauer et al. (1971). The revised 30-300-micron brightness temperatures are: Jupiter, 127 + or - 3 K; Saturn, 85 + or - 2 K; and Venus, 240 + or - 8 K. The Jupiter value agrees with the Pioneer 10 and Pioneer 11 radiometer experiment. A table of Mars brightness temperature up to October 1978 is given.
