 Although European manned spaceflight, performed by ESA, is dependent on US or Russian launches, most European astronauts have worn a patch designed for their particular mission (apart from some of the earlier Shuttle flights, when ESA astronauts wore the same crew patches as their NASA colleagues).ESA patches are designed either by the agency's graphics teams or occasionally by members of the public through competitions organized by ESA.ESA maintains a patch gallery of every patch worn by its astronauts.
