Found it! Phys.org's Japan rocket with manga art launches satellite into space:
Japan's H-2A rocket, carrying a Himawari-9 weather satellite, (was) launched on Tanegashima Island on November 2, 2016
Japan's domestically developed mainstay rocket carried two pieces of manga artwork originally drawn by Chuya Koyama, known for his comic book on two brothers who dream about becoming astronauts.
"We believe it's the first time in the world to launch a rocket with manga art on it," said Hirokazu Kosada of Young Astronauts Club Japan, the foundation that organised the rocket art project.
The artworks were created by using 30,000 digital images of photographs and paintings sent by children across Japan, according to Kosada.
