STS067-713-072 (2-18 March 1995) --- This 70mm cargo bay scene, backdropped against a desert area of Namibia, typifies the view that daily greeted the Astro-2 crew members during their almost 17-days aboard the Space Shuttle Endeavour. Positioned on the Spacelab pallet amidst other hardware, the Astro-2 payload is in its operational mode. Visible here are the Instrument Pointing System (IPS), Hopkins Ultraviolet Telescope (HUT), Star Tracker (ST), Ultraviolet Imaging Telescope (UIT), Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE), and Integrated Radiator System (IRS). At this angle, the Optical Sensor Package (OPS) is not seen. The Igloo, which supports the package of experiments, is in center foreground. Two Get-Away Special (GAS) canisters are in lower left foreground. The Extended Duration Orbiter (EDO) pallet, located aft of the cargo bay, is obscured by the Astro-2 payload. The Endeavour was 190 nautical miles above Earth.

STS067-371-028 (2-18 March 1995) --- This 35mm lunar-illuminated scene of the Astro-2 payload in the Space Shuttle Endeavour's cargo bay was recorded by one of by the seven crew members during one of the many night passes of the almost 17-day mission. The cluster of telescopes and the Instrument Pointing System (IPS) are backdropped against the blue and white Earth and the darkness of space. What is believed to be the Constellation Orion is visible at upper center.

S93-33258 (15 Mar 1993) --- An optical schematic diagram of one of the four channels of the Wide Field\Planetary Camera-2 (WF\PC-2) shows the path taken by beams from the Hubble Space Telescope (HST) before an image is formed at the camera's charge-coupled devices. A team of NASA astronauts will pay a visit to the HST later this year, carrying with them the new WF/PC-2 to replace the one currently on the HST. The Jet Propulsion Laboratory in Pasadena, California has been working on the replacement system for several months. See NASA photo S93-33257 for a close-up view of tiny articulating mirrors designed to realign incoming light in order to make certain the beams fall precisely in the middle of the secondary mirrors.

51F-33-005 (29 July - 6 August 1985) --- Experiments and the instrument pointing system (IPS) for Spacelab 2 are backdropped against the Libya/Tunisia Mediterranean coast and black space in this 70mm view photographed through the aft flight deck windows of the Space Shuttle Challenger. Also partially visible among the cluster of Spacelab 2 hardware are the solar optical universal polarimeter (SOUP) experiment and the coronal helium abundance experiment (CHASE).

STS067-377-008 (2-18 March 1995) --- Astronaut John M. Grunsfeld, mission specialist, uses a handheld Hasselblad camera to record the Astro-2 payload. Orbiting Earth at 190 nautical miles, Grunsfeld joined four other NASA astronauts and two scientists for almost 17 days conducting research in support of the Astro-2 mission.

STS056-91-050 (8-17 April 1993) --- This 70mm frame shows the cargo bay of the Earth-orbiting Space Shuttle Discovery backdropped against clouds. Most of the elements of the ATLAS-2 payload can be seen, but missing is the SPARTAN-201 satellite which was in the midst of its separation from Discovery when the photo was made.

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).
