STS-67 Patch

Mission Highlights Endeavour logged 6.9 million miles (11 million kilometers) in completing the longest shuttle flight to date, allowing sustained examination of the “hidden universe” of ultraviolet light. Primary payload, Astro Observatory, flown once before — on STS-35 in December 1990 — but second flight had almost twice the duration. Planned Astro-2 observations built on discoveries made by Astro-1, as well as seeking answers to other questions. Astro-2 marked the second flight of three ultraviolet telescopes flown on Astro-1, mounted on Instrument Pointing System on Spacelab pallet in cargo bay. Hopkins Ultraviolet Telescope (HUT), developed at the Johns Hopkins University, performs spectroscopy in far ultraviolet region of spectrum to identify physical processes and chemical composition of a celestial object. Improvements made to HUT after Astro-1 made it three times more sensitive. Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE), built at the University of Wisconsin,
