NASA launches Space Shuttle Atlantis on the 46th shuttle mission, carrying the Spacelab-based ATLAS (Atmospheric Laboratory for Applications and Science) experiment module. Aboard Atlantis for the nearly-nine-day flight are Commander Charles Bolden, Pilot Brian Duffy, Payload Commander Kathyrn Sullivan, mission specialists David Leestma and Michael Foale, and payload specialists Byron Lichtenberg and Dirk Frimout. NASA extends the mission by one day to accomodate additional experiments.
