Micrometeorite Microphone

NSSDCA ID: 1960-014A-05

Mission Name: Explorer 8
Principal Investigator:Mr. Curtis W. McCracken


Two piezoelectric crystals, each attached to two sounding boards acoustically isolated from the satellite skin, were used to measure the frequency and momentum of micrometeorite impact. Information from these sensors was obtained in low-, medium-, and high-sensitivity levels and stored in three independent digital counters. The experiment performed normally.
