Mission objectives

Columbia was to carry the ASTRO-1 observatory, which would be used to make astronomical observations including observations of Comet Halley. ASTRO-1 consisted of three ultraviolet telescopes mounted on two Spacelab pallets, controlled by the Instrument Pointing System which was first tested on STS-51-F.[1]

After the Challenger disaster, the flight was remanifested as STS-35 and several crew members were replaced. Both Richards and Leestma were reassigned to STS-28 while McBride left NASA in 1989. Vance Brand replaced McBride as the commander while Guy Gardner and Mike Lounge replaced Richards and Leestma, respectively.
