Micrometeorite flux determined from the 1965 Luster sounding rocket collection.

Electron microscopic examination of collection surfaces flown on a sounding rocket to sample micrometeorites at altitudes from 60 to 145 km above the earth's surface revealed fewer micrometeorites than anticipated. A double shadowing technique was used to distinguish between possible micrometeorites and contaminants. From the number of possible micrometeorites present, estimates were made of the maximum possible flux of micrometeorites above the atmosphere at the time of sampling. The derived maximum flux of 7 × 10¹ particles greater than 0.1 micron in diameter per square meter per second is significantly smaller than flux estimates based on satellite data and data from previous rocket collection experiments.
