註釋Meteoroid experiments by five Lunar Orbiters have provided a direct measurement in the near-lunar environment of the rate of meteoroid penetration of 0.025-mm-thick beryllium-copper. Each experiment used 20 pressurized-cell detectors having a total effective exposed area of 0.186 m2. The spacecraft carrying the cells were in both equatorial and polar orbits; altituded ranged between 30 and 6200 km. Data collected continuously for 17 months indicate that the rate of penetration in the lunar environment is approximately half the rate in the near-earth environment as measured by detectors of the same type aboard Explorers XVI and XXIII.
