STS-57 Endeavour, Orbiter Vehicle (OV) 105, crew insignia (logo), the official insignia of the NASA STS-57 mission, depicts the Space Shuttle Endeavour maneuvering to retrieve the European Retrievable Carrier (EURECA) microgravity experiment satellite. Spacehab -- the first commercial space laboratory -- is depicted in the cargo bay (payload bay (PLB)), and its characteristic shape is represented by the inner red border of the patch. The three gold plumes surrounded the five stars trailing EURECA are suggestive of the United States (U.S.) astronaut logo. The five gold stars together with the shape of the orbiter's mechanical arm form the mission's numerical designation. The six stars on the American flag represent the U.S. astronauts who comprise the crew. With detailed input from the crewmembers, the final artwork was accomplished by artist Tim Hall. The names of the STS-57 flight crewmembers are located along the border of the patch. They are Commander Ronald J. Grabe, Pilot Brian J. Duffy, Mission Specialist (MS) and Payload Commander (PLC) G. David Low, MS 2 Nancy J. Sherlock, MS3 Peter J.K. Wisoff, MS4 Janice E. Voss.Each crewmember contributed to the design of the insignia.
