The Space Brothers manga is concluding with its 46th volume on July 22, 2026, and a special chapter, 425.5, will be drawn in space via a robotic arm on the ISS as part of Mission: SPACE COMIC.
Kodansha announced Mission: SPACE COMIC on June 11, 2026, a project to draw a special chapter of Space Brothers aboard the International Space Station. The chapter, numbered 425.5, will be produced using a robotic arm inside the Kibo module. The arm will replicate the hand movements of creator Chuya Koyama, drawing the manga in microgravity. The project is the first commercial use of JAXA's new robotic arm, operated remotely from the ground by Space Entry Co., Ltd.
The special chapter will be released on July 22, 2026, alongside the final 46th volume of the manga. The project turns a fictional technology from the series into a real-world engineering demonstration, testing whether delicate creative work like manga drawing can be reliably performed under the constraints of space. Kodansha announced the mission on June 11, and additional details about the robotic arm's operation were provided on June 16.
