Portion of the structure from a full-scale replica of the Infrared Astronomical Satellite (IRAS; Cat# 19870107000). The replica was constructed by Ball, 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. This replica was displayed in several local displays in Colorado prior to shipping to NASM. IRAS was donated to the Museum by the Ball Corporation in April 1987.
