The mission logo mark of the "AKATSUKI" was designed by reflecting its original nickname, "VCO," the abbreviation of the Venus Climate Orbiter, which has been used since the initial study phase. In the logo, the AKATSUKI is flying over Venus, which is shown by "O" in the drawing, on an orbit depicted by "C." It was designed by the AKATSUKI project team.
Two mascot characters "AKATSUKI-KUN" and "KINSEI-CHAN" were also introduced for people to feel more familiar with the AKATSUKI.
"AKATSUKI-KUN" is the satellite name with the honorific title of "KUN" in Japanese for a little boy. "KINSEI-CHAN" reflects the Japanese name of Venus (KINSEI) with the honorific title of "CHAN" for a little child.
