STS-35 Astro-1 telescopes, in their on-orbit operating
configuration, are documented in the payload bay of Columbia.
To the right of the Astro-1 payload is the constellation Orion.
The three ultraviolet telescopes are mounted and precisely
aligned on a common structure, called the cruciform, that is
attached to the instrument pointing system (IPS). Visible here
are the star tracker (silver cone at the far left), the Hopkins
Ultraviolet Telescope (HUT), and the Wisconsin Ultraviolet
Photo-Polarimeter Experiment (WUPPE) (to the right of HUT).
Since the photo was taken during orbital night, the payload
is being illuminated only by scattered light from the nearly
full moon. (Astro-1)
