Rocket Infrared Spectroscopy of the Zodiacal Dust Cloud

Abstract

The 8-14 micrometer infrared spectrum of the zodiacal dust cloud has been measured with a resolution of delta lambda/lambda approximately equal to 0. 03. The observations were made with a liquid helium cooled array spectrometer and telescope from an altitude of approximately equal to 300km. The design, testing, and calibration of the rocket payload are described. Technical problems occurred during the flight that destroyed approximately equal to 90 percent of the data. However, one good scan across the ecliptic plane at a solar elongation of approximately equal to 103 degrees was obtained. The spectrum shows a pronounced silicate emission feature similar to that seen in carbonaceous chondrites and in the Orion Nebula, along with a dilute underlying blackbody.
