Two Japanese companies, Takasago Thermal Engineering and ispace, have joined forces to achieve the ambitious goal of producing hydrogen on the moon. Takasago has designed a mini electrolyzer specifically tailored to function in low gravity and withstand the intense vibrations of a rocket liftoff. The hydrogen-making machine will operate remotely from ispace's Mission Control Centre in Tokyo during the upcoming mission set to launch by the end of 2024. The mission involves bringing a small amount of Earth water to the moon for electrolysis, with the long-term vision of eventually extracting hydrogen from lunar water on future missions. Challenges such as adapting to the low moon gravity have been highlighted, emphasizing the experimental nature of this groundbreaking endeavor. If successful, the mission could pave the way for utilizing hydrogen as a propellant for spacecraft, potentially revolutionizing space exploration capabilities. Ispace's improved lander, equipped with the electrolyzer and a rover for data collection on the lunar surface, is poised for launch in late 2024. The ultimate goal is to establish a moon gas station, enabling extended space habitation and exploration. The collaboration marks a significant step forward in space technology, offering new possibilities for utilizing resources beyond Earth and opening up avenues for further missions and advancements in space travel.
