STS035-35-007 (2-10 Dec 1990) --- During the STS-35 mission, the Astronomy Laboratory 1 (ASTRO-1) payload, in its on-orbit operating configuration in the payload bay (PLB), is silhouetted against the firing of a reaction control system (RCS) jet. In the center of the frame, three ultraviolet telescopes are mounted and precisely co-aligned on a common structure, called the cruciform, that is attached to the instrument pointing system (IPS). Visible on the cruciform are Integrated Radiator System (IRS) (silver box on left), the Optical Sensor Package (OSP) (above IRS), the Ultraviolet Imaging Telescope (UIT), and the star tracker (S TRK) (far right). A right RCS jet is fired during this maneuver of Columbia, Orbiter Vehicle (OV) 102.

STS035-13-008 (2-10 Dec. 1990) --- The various components of the Astro-1 payload are seen backdropped against the blue and white Earth in this 35mm scene photographed through Columbia's aft flight deck windows. Parts of the Hopkins Ultraviolet Telescope (HUT), Ultraviolet Imaging Telescope (UIT) and the Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) are visible on the Spacelab Pallet in the foreground. The Broad Band X-Ray Telescope (BBXRT) is behind this pallet and is not visible in this scene. The smaller cylinder in the foreground is the "Igloo," which is a pressurized container housing the Command and Data Management System, which interfaces with the in-cabin controllers to control the Instrument Pointing System (IPS) and the telescopes.

STS035-28-006 (2-10 Dec 1990) --- STS-35 Astronomy Laboratory 1 (ASTRO-1) telescopes, in on-orbit operating position in the payload bay (PLB), are silhouetted against an reaction control system (RCS) right thruster firing. Three ultraviolet telescopes are mounted and precisely co-aligned on a common structure, called the cruciform, that is attached to the instrument pointing system (IPS). Here the IPS holds the telescopes in a position that is parallel to the Earth's limb below. Visible on the cruciform are the star tracker (S TRK) (silver cone at the top), the Ultraviolet Imaging Telescope (UIT) (behind S TRK), and the Hopkins Ultraviolet Telescope(HUT).
