Image Credit: NASA Mission HighlightsThree communications satellites, all attached to the Payload Assist Module-D (PAM-D) motors, were deployed: MORELOS-A, for Mexico; ARABSAT-A, for Arab Satellite Communications Organization; and TELSTAR-3D, for AT&T. Also flown: deployable/retrievable Shuttle Pointed Autonomous Research Tool for Astronomy (SPARTAN-1); six Get Away Special canisters; Strategic Defense Initiative experiment called the High Precision Tracking Experiment (HPTE); a materials processing furnace called Automated Directional Solidification Furnace (ADSF); and two French biomedical experiments.

By the end of his seven days in space, Sultan Abdul-Aziz Al-Saud had given up looking for his own country, or even his own continent, and came to realize that all humans belonged to just “One World.” It is a message which continues to resonate today. Photo Credit: NASA
