Abstract

We present an overview of the ongoing progress towards flight readiness of the SIM project. We summarize the engineering milestones that have been completed in the last two years, namely: the Brass-Board Internal and External Metrology Beam Launchers, the Brass-Board Metrology Source, and the Instrument Communication Hardware/Software Architecture Demonstration. We also show other progress such as: the life test of the bass-screw and PZT actuators, building the Metrology Fiducials and the Single Strut Test Article. We status the ongoing work on the Brass-Board Fast Steering Mirror and the Brass-Board Astrometric Beam Combiner. We end with a proposed path towards finishing the Brass-Board suite.
