Abstract
Fourteen windows of the Gemini spacecraft were closely examined after return from space flight for evidence of meteoroid impact. Although a number of microscopic pits were found on each window, only one of these pits appears to have been caused by a meteoroid impact. A meteoroid flux-mass relation calculated from this single hit is found to be in close agreement with Naumann's (1966) analysis of the Explorer and Pegasus meteoroid penetration experiments. Particle, mass, and area distribution curves are derived from the flux-mass relation and are presented in graphical form. Problems in interpreting the data because of contaminants on the windows are also discussed.
