Zodiacal Light Photometer

NSSDCA ID: 1974-097A-11

Mission Name: Helios-A
Principal Investigator:Dr. Christoph Leinert


This experiment (E9) consisted of three photometers looking at 15 deg, 30 deg, and 90 deg from the ecliptic. These photometers observed the intensity and polarization of the zodiacal light in UV, blue, and visual bands. The purpose of this experiment was to obtain information about the spatial distribution, size, and nature of interplanetary dust particles. For further details, see pp. 264-267 of Raumfahrtforschung, v. 19, n. 5, 1975.
