This is one of two simulated solar panels from a full-scale replica of the Infrared Astronomical Satellite. Ball Brothers Aerospace Corporation constructed this replica, with assistance from the Jet Propulsion Laboratory, Perkin-Elmer and the Netherlands Aerospace Agency. Reconstruction began in mid-1986 using backup and leftover parts, with some new components.
IRAS and these solar panels were donated to the Museum by the Ball Corporation in April 1987.
