China recovers Long March 10B booster at sea after maiden flight

China recovered part of the Long March 10B reusable rocket on its maiden flight, marking the country’s first controlled orbital-class booster recovery and making China the second nation to achieve that feat. The 70 metre tall, 5 metre wide medium-lift rocket lifted off from Wenchang at 12.15pm; about six minutes after stage separation the first stage returned vertically and was recovered by a sea platform, state broadcaster CCTV reported. Unlike SpaceX’s legged landings, Long March 10B used a sea-based net-and-cable capture system that absorbs the booster’s remaining energy during final descent. The two-stage booster is powered by seven YF-100K kerosene/liquid-oxygen engines, can deliver up to 16 tonnes to low Earth orbit, and is primarily designed for cargo missions. The flight validated first-stage reusability for the Long March 10 family and is a step toward the more powerful crewed lunar Long March 10, which would use 21 YF-100K engines at liftoff for lunar missions planned before 2030. The mission followed February tests in which a Long March 10A stage completed a controlled descent during an in-flight abort, and it comes after recent failed vertical-landing attempts by other Chinese rockets, including Zhuque-3 and Long March 12A. CCTV said another Long March 10B reusable launch and a full Long March 10A flight are expected later this year.
