This Klingon mission patch was designed by astronaut and current ISS commander Steve Swanson as the official Expedition 40 crew patch. Unfortunately, due to copyright concerns, the patch had to be redesigned.
[He] collaborated with his daughter to create an insignia for the outpost’s Expedition 40 crew. What he and his fellow astronauts and cosmonauts ultimately launched with to the space station was a patch depicting the “past, present, and future of human space exploration.”
What Swanson had first proposed however, was a badge of a decidedly different type.
“He wanted something that was kind of badass,” revealed Mary Swanson, Steve’s wife, in a call with collectSPACE, “and Klingons are kind of badass.”
