Abstract Recent investigations have discovered evidence of micron and submicron impacts on returned spacecraft surfaces which have been exposed in near earth space. These craters are generally assumed to be due to particles of near earth origin. The theoretical possibility that some of them could be due to impacts caused by lunar ejecta, as well as the possibility that lunar ejecta may exist in enhanced spatial density regions of the earth's magnetosphere between L values of 1.7 and 3.0, is discussed. A comparison of trapping dynamics is made between micron and submicron debris injected into the earth's magnetosphere during solid rocket propellent burns and ejecta in the earth's magnetosphere originating on the lunar surface. The possible effects of particle charging on trapping and quasi-trapping in this size range are discussed.
