Spectrum of the cosmic background radiation between 3 mm and 800 µm

Abstract

WE report the successful flight of an experiment designed to measure the spectrum of the cosmic background radiation from 3 mm to wavelengths shorter than the Planck peak for a temperature of 2.7 K. The experiment was launched, to an altitude of 40 km, on March 13, 1974, from Palestine, Texas. Because of an on-site computer fault, the complete data were not available to us until May 7, 1974. The instrument has been described previously1,2 and will be discussed in detail in a future paper; we present here the results of preliminary analysis of the flight data.
