An Educational Comic About NASA's Global Precipitation Measurement Mission. In the spring of 2013, the Global Precipitation Measurement (GPM) mission hosted the GPM Anime Challenge, a contest for artists of all ages around the world to develop an anime-themed comic book character to teach students about the mission. The Japanese anime / manga style of art was chosen because the mission is a collaboration between NASA and JAXA, the Japan Aerospace Exploration Agency. At the end of the contest two grand prize winners were selected. "GPM" by Yuki Kiriga, and "Mizu-Chan" by Sabrynne Buchholz.
