Extremely rare NASA first generation paper model of the Hubble Space Telescope, standing approximately 13″ in height and 12″ wide with extended solar array panels, signed on the underside of the upper lid in silver ink, “Jeffrey Hoffman, STS-61, (SM-1).” The carefully detailed model, with articulating high gain antennae, has every panel and bay labeled for easy reference. This working model originates from the Hubble Program Office at the Goddard Space Flight Center and was used as a reference by NASA engineers and Mission Control personnel in the event of any unforeseen issues. In fine condition, with light overall staining from exposure to cigarette smoke. Models such as this one can be viewed in various NASA documentaries pertaining to the earlier Hubble Service Missions. A handsomely rendered working NASA model that falls into the ‘endangered’ category—a remote handful of these models have survived over the years, with this example all the more desirable for its superb condition.
