Mission Name: Pioneer 11The Pioneer 11 infrared radiometer experiment measured the Jovian and Saturnian thermal balance, temperature distribution in the outer atmosphere, general surface composition (including the overall hydrogen-to-helium ratio), and dark-side temperature. The instrument consisted of a 7.62-cm reflecting Cassegrain telescope with a 1-deg by 3-deg field of view that illuminated a pair of 88-channel, thin-film bimetallic thermopiles in two bands of the IR spectrum (14 to 25 micrometers and 19 to 56 micrometers) to measure the irradiance. The two-channel radiometer was similar to those flown on Mariners 6 and 7, but was more accurate and had better spatial resolution. This instrument was turned off in October 1979.
