This is our best effort of a reproduction of this patch design. Columbia was to carry the ASTRO-1 observatory, which would be used to make astronomical observations including observations of Halley's Comet. ASTRO-1 consisted of three ultraviolet telescopes mounted on two Spacelab pallets, controlled by the Instrument Pointing System (IPS) which was first tested on STS-51-F. This mission, along with space shuttle launches from the west coast, was canceled following the Challenger disaster in January 1986. The flight was later manifested as STS-35. If STS-61E had flown as planned, the flight details would have been: Launch Date: March 6, 1986 Launch Vehicle: Discovery Crew: Commander: Jon A. McBride Pilot: Richard N. Richards Mission Specialists: Jeffrey A. Hoffman, David C. Leestma, Robert A. Parker Payload Specialists: Samuel T. Durrance, Ronald A. Parise Reproduction of this design from the source material was guided by David T. Pinson working with the AB Emblem design team. Approximately 4" x 4 1/2"
