Yes, that's Groot and Rocket Raccoon in this official NASA patch. It will represent all of the science missions of the US National Laboratory on board the International Space Station during 2016. The Center for the Advancement of Science in Space (CASIS) worked with Marvel artist Juan Doe to develop the design. Space.com reports:
"A major mission for us here at CASIS is to find unique and innovative ways to bring notoriety to the International Space Station National Laboratory and the research that is being conducted," stated Ken Shields, CASIS's operations and educational opportunities director. "There are very few brands in the world who have as large an impact as Marvel and we are thrilled to partner with them on this project."
