Japan’s space agency JAXA studying new reusuable rocket concepts
Even as it struggles to complete the first launch of its H3 hydrogen-fueled expendable rocket, Japan’s space agency JAXA has begun study work on new reusuable rocket concepts, working with its long-time rocket partner Mitsubishi.
Few details were released, but it appears they are studying a replacement for the H3, possibly using methane fuel rather than hydrogen (which is very difficult and expensive to handle), that would be ready for launch in the 2030s.
Meanwhile, the H3 remains grounded after its March 2023 launch failure, when its upper stage engine failed to ignite. No new launch date has been set. Because Japan has no more H2A rockets left, and its smaller Epsilon rocket is also grounded due to launch and test problems, JAXA right now has no capability to launch anything.
Japan’s policy towards space was changed this year to encourage the development of independent, privately owned rockets, but this transition from government-run to commercial has barely begun, and might not go anywhere based on this new study. It appears both JAXA and Mitsubishi are fighting to hold onto their turf.
