Hubble's third-generation rigid solar array tested at ESTEC in the Large Space Simulator (LSS) test chamber, which was not available when the earlier European-made Hubble arrays had been constructed. The technicians prepare to disconnect it from the crane. This US array is a third smaller than previous European designs, with no need for flexibility since it is not going to be returned to Earth on a Space Shuttle.
