Image Caption: STS-35 Astronomy Laboratory 1 (ASTRO-1) telescopes, in onorbit configuration, are documented in the payload bay (PLB) of Columbia, Orbiter Vehicle (OV) 102, and backdropped against the blue and white surface of the Earth. In the center of the frame are three ultraviolet telescopes mounted and precisely coaligned on a common structure, called the cruciform, that is attached to the instrument pointing system (IPS). Visible on the cruciform are the star tracker (S TRK) (silver cone at far left), the Hopkins Ultraviolet Telescope (HUT), and the Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) (at top right). In the foreground and located at the head of the unpressurized spacelab pallet (U-pallet) is the igloo, a pressurized cylindrical container that houses subsystems that provide such services as power, telemetry and commands to the instruments.
