The International Space Station Expedition 38 Crew Patch signifies how the Space Station has become humanity's stepping stone to future space exploration. The patch represents a visual roadmap of Exploration Targets beyond Low Earth Orbit.
The flowing Expedition 38 numbers wrap around Earth before reaching out to the Moon and ultimately Mars.
"Just as the sun is a guiding light in the galaxy, the ISS illuminates the bottom of the design as it is a shining beacon of the advancement of science, knowledge, and technology carried out aboard the Space Station," the NASA description of the patch said.
The use of red, white and blue represents the flags of the countries of origin of the six crew members.
