Meteoroid Detectors

NSSDCA ID: 1967-041A-03

Mission Name: Lunar Orbiter 4
Principal Investigator:Mr. Charles A. Gurtler

Description

Twenty 0.025-mm beryllium copper pressurized cell detectors were used to provide direct measurements in the near-lunar environment of the rate of penetration by micrometeoroids. The detectors were arranged on the periphery of the tank deck. Each cell was a helium pressurized semicylinder with a pressure sensitive switch that remained closed until pressure was released by puncture of the cell's surface. Meteoroid hits were recorded by discrete telemetry channel state changes. The total exposed area of the detectors was 0.282 sq m, and the effective area after shielding by other components was 0.186 sq m. Two micrometeoroid hits were recorded during the photographic mission phase of the flight.
