BALL'S CORRECTIVE OPTICS FOR HUBBLE SPACE TELESCOPE EXCEEDS SPECIFICATIONS FOR CORRECTING THE SPHERICAL ABERRATION

 BOULDER, Colo., July 1 /PRNewswire/ -- As Ball Corp. (NYSE: BLL) prepares to deliver the Corrective Optics Space Telescope Axial Replacement (COSTAR) instrument in early July to NASA's Goddard Space Flight Center, three independent verification methods indicate that COSTAR will meet and, in most cases exceed, its specifications for correcting the spherical aberration on NASA's Hubble Space Telescope (HST) for the Goddard High Resolution Spectrograph, the Faint Object Camera and the Faint Object Spectrograph.
 "We couldn't be more pleased with these results," said Ball's Electro-Optics and Cryogenics Division Senior Vice President and General Manager Dr. Ed Vande Noord, "not only are we meeting, but in most cases exceeding, the customer's optical requirements for COSTAR. This result is a real tribute to the Ball, NASA/Goddard and the Space Telescope Science Institute team that worked so diligently to develop COSTAR."
 Ball has completed COSTAR environmental testing including a full complement of "before and after" optics verification testing. COSTAR performed simulated "on-orbit" electrical functions during the most severe thermal vacuum environments. The "before and after" optics testing was performed using three independent verification methods in Ball's cleanroom: 1) a structural model of the European Space Agency's Faint Object Camera; 2) the Ball Image Analyzer; and, 3) the Independent Verification Team's Aberrated Beam Analyzer.
 All methods indicated that Ball has exceeded most of the performance specifications on all five pairs of optics used to correct the Ball- built Goddard High Resolution Spectrograph, the Faint Object Camera and the Faint Object Spectrograph instruments for the HST optics aberrations.
