EXPRESS PPU POWER PROPULSION UNIT 160 CIRCUIT BOARDS FOR POWER UNIT OF ION THRUSTER

Environmental Portrait, Electrical Power Systems Employee, hardware for the High Power 300-Volt Power Processing Unit (PPU). The Printed Circuit Boards (PCBs) are the Discharge Module Inverter and the Pulse Width Modulation (PWM) Controller

KENNEDY SPACE CENTER, FLA. -- In Vehicle Assembly Building (VAB) high bay 4, installation of a Payload Bay Door Drying Enclosure is in progress. The enclosure will keep moisture from being absorbed into the graphite epoxy used on the payload bay doors of the Shuttle orbiters with the assistance of mini-Portable Purge Units (PPUs). Once in operation, the enclosure will allow NASA the option to store an orbiter in the VAB bay up to 180 days in a "standby-to-stack" mode.
