The STS-100/6A emblem reflects the complex interaction of robotics and extravehicular activity (EVA) on this mission.
Endeavour's payload bay houses a Spacelab pallet, itself holding the SSRMS and the Space Station Ultra High Frequency Antenna, and the Italian-built Multi-Purpose Logistics Module "Raffaello." American, Russian, Canadian, and Italian astronauts compose the crew, and their flags are stylized in the lower portion of the emblem. Source: NASA
