Collection Item Summary:
This is the engineering prototype of the optical telescope and spectrograph, carried by the third Orbiting Astronomical Observatory (OAO III) called "Copernicus." The telescope, known as the Princeton Experiment Package, consisted of an 82-cm (32-inch) parabolic mirror and a high-resolution spectrograph mounted at a modified Cassegrain focus. Launched on August 21, 1972, Copernicus was the second successful satellite in the OAO series. Over a 9-year period, Copernicus observed the ultraviolet spectra of stars, galaxies, a nova, and the interstellar medium. It provided new information about how stars form and age. Transferred from NASA in 1973.
