Hubble Space Telescope mirror under construction at Perkin-Elmer. The construction of the main mirror was begun in 1979 and completed in 1981. However,the polishing ran over budget and behind schedule,producing significant friction with NASA. Due to a miscalibrated null corrector,the primary mirror was also found to have a significant spherical aberration after reaching orbit. A NASA investigation heavily criticized Perkin-Elmer for management failings,disregarding written quality guidelines,and ignoring test data that showed this miscalibration | |
