| Summary | Japan's next-generation flagship rocket designed to halve H-IIA costs. Uses three LE-9 engines burning liquid hydrogen — the highest-performing expander-cycle engines in the world. First successful flight was TF2 (Feb 17, 2024). HTV-X1 cargo mission to ISS (Oct 2025) demonstrated operational readiness. | The world's first methane-fueled rocket to achieve orbit (July 12, 2023), beating SpaceX Starship to that milestone. A commercial Chinese rocket built by LandSpace with vertically-integrated methane propulsion — the same propellant strategy as Starship, Neutron, and Terran R. | JAXA's small solid-fuel rocket derived from the M-V rocket heritage. Designed for highly autonomous operations — launch preparations could be managed by just 8 people. The sixth and final E-6 mission (Oct 2022) failed when the PBS kick stage didn't ignite; a ground explosion during Epsilon S testing (Jan 2023) ended the programme. |
