Abstract
Charging of the isolated proof masses which form the mirrors defining the path lengths for the LISA and LISA Pathfinder (LISAPF) interferometers turns out to be one of the limiting sources of spurious noise for both missions. An overview of the charging effects and processes will be given which set the scale of the charge-induced noise contributions within the overall LISA sensitivity budget. The current charge control hardware and operations for LISAPF will be described, followed by a forward look to the necessary further developments needed for LISA. [ABSTRACT FROM AUTHOR]
