  Title: STS-50 Columbia, Orbiter Vehicle (OV) 102, crew insignia
  STS-50 Columbia, Orbiter Vehicle (OV) 105, crew insignia (logo), the
  official  insignia of the NASA STS-50 United States Microgravity Laboratory
  1 (USML-1)  mission, captures a Space Shuttle traveling above Earth while
  trailing the  USML banner.  The orbiter is oriented vertically in a typical
  attitude for  microgravity science and in this position represents the
  numeral 1 in the  mission's abbreviated title.  This flight represents the
  first in a series of  USML flights on which the primary objective is
  microgravity science, planned  and executed through the combined efforts of
  America's government, industry  and academia.  Visible in the payload bay
  (PLB) are the Spacelab module, and  the extended duration orbiter (EDO)
  "cryo" pallet which will be making its  first flight.  The small g and
  Greek letter mu on the Spacelab module  symbolize the microgravity
  environment being used for research in the areas  of materials science and
  fluid physics.  The large block U extends outside  the patch perimeter,
  symbolizing the potential for the experiments on this  flight to expand the
  current boundaries of knowledge in microgravity science.  The Stars and
  Stripes of the USML block letters and the U.S. landmass in the  Earth scene
  below reflect the crew's pride in the U.S. origin of all onboard 
  experiments. The STS-50 flight crewmembers are Commander Richard N.
  Richards,  Pilot Kenneth D. Bowersox, Mission Specialist (MS) and Payload
  Commander  (PLC) Bonnie J. Dunbar, MS Ellen S. Baker, MS Carl J. Meade,
  Payload  Specialist Lawrence J. DeLucas, and Payload Specialist Eugene H.
  Trinh.  Each  crewmember contributed to the design of the insignia.
