  Title: STS-54 Endeavour, Orbiter Vehicle (OV) 105, crew insignia
  STS-54 Endeavour, Orbiter Vehicle (OV) 105, crew insignia (logo), the 
  official insignia of the NASA STS-54 mission, depicts the American bald
  eagle  soaring above Earth and is emblematic of Space Shuttle Endeavour in
  service  to the United States and the world.  The eagle is clutching an
  eight-pointed  star in its talons and is placing this larger star among a
  constellation of  four others, representing the placement of the fifth
  Tracking and Data Relay  Satellite (TDRS) into orbit to join the four
  already in service.  The  blackness of space -- with stars conspicuously
  absent -- represents the  crew's other primary mission in carrying the
  Diffuse X-Ray Spectrometer to  orbit to conduct astronomical observations
  of invisible x-ray sources within  the Milky Way Galaxy.  The depiction of
  the Earth showing North America is an  expression of the crewmembers and
  NASA's intention that the medical and  scientific experiments conducted
  onboard be for the benefit of mankind.  The  clouds and blue of the Earth
  represent the crew's part in NASA's Mission to  Planet Earth in conducting
  Earth-observation photography.  The names of the  STS-54 flight crewmembers
  are located along the border of the patch.  They  are Commander John H.
  Casper, Pilot Donald R. McMonagle, Mission Specialist 1  (MS1) Mario Runco,
  Jr, MS2 Gregory J. Harbaugh, and MS3 Susan J. Helms.  Each  crewmember
  contributed to the design of the insignia.
