NASA GSFC reached out to Newton to develop full-scale mock-ups of the WFIRST spacecraft and the WFIRST Instrument Carrier.  The WFIRST spacecraft mock-up is a 14 foot wide hexagon that straddles two dollies and “splits open” like a clam, allowing passer-by full view of the propulsion tanks and high gain antenna (HGA) embedded inside of the spacecraft. Of the six spacecraft “modules”, Newton’s contract included developing a fully-detailed module and radiator panel that includes 4 connectorized electronics boxes. Additionally, the WFIRST Instrument Carrier mock-up is a 1:1 scale structure constructed from riveted aluminum box beams and composite tubes. Both the spacecraft and the instrument carrier were wrapped with simulation carbon fiber composite material to offer the final aesthetics that would be expected from a composite structure.
