Abstract : The transfer of contaminants in spacecraft by desorption is examined. In this mechanism, contaminants are transferred in an apparent non-line-of-sight manner by first being adsorbed on and subsequently desorbed from a transfer surface. The parameters governing the kinetics of contaminant build-up on a collector surface are determined and discussed. (Modified author abstract)
