When you think of an astronaut’s job description, art design may not be the first thing that comes to mind. However, the astronaut crews on each mission are in charge of designing their team's mission patch. 

Unlike other NASA missions, for trips to the ISS astronauts wear two patches as opposed to just one. This is because ISS crews overlap. Astronauts travel to the ISS in groups of three and join a crew of three other astronauts already aboard. These six astronauts form the Expedition, and are represented by a mission patch. About halfway through their time aboard the ISS, half the crew departs. The remaining three are joined by another crew of astronauts, forming a new Expedition and requiring a second patch.  For example, NASA astronaut Randy “Komrade” Bresnik wears the Expedition 52 and 53 mission patches.
