Micrometeorite Spectrometer

NSSDCA ID: 1960-001A-04

Mission Name: Pioneer 5
Principal Investigator:Dr. Maurice Dubin


A micrometeorite detector (micrometeorite momentum spectrometer), which consisted of two diaphragm and microphone combinations, was used to measure the number and momentum of meteoritic dust particles at various distances between the orbits of Earth and Venus. The outputs from the piezoelectric microphones were connected in parallel to the electronics so that it was not possible to tell which of the individual detectors was hit. The experiment produced no meaningful data because the data system saturated and failed to operate properly as a counter of impulses from the micrometeorite detector.
