Micrometeorite

NSSDCA ID: 1958-007A-03

Mission Name: Pioneer 1
Principal Investigator:Dr. Maurice Dubin

Description

A diaphragm/microphone micrometeorite detector assembly that permitted a two-level discrimination of impact energy was designed to determine micrometeorite density in interstellar space. The area of the exterior diaphragm equaled a predetermined fraction of the total surface area of the spacecraft. Results were limited because of a vehicle failure which caused the spacecraft to reenter the atmosphere over the South Pacific on October 12, 1958.
