China Recovered its First Reusable Rocket and Showed a New Way to Do It

China's sprawling state-owned rocket developer, maker of the country's Long March rocket family, announced it recovered a reusable orbital-class booster for the first time Friday in the South China Sea.
The milestone mission began with the liftoff of a Long March 10B rocket from the Wenchang Commercial Space Launch Site on Hainan Island, China's southernmost province. Powered by seven kerosene-fueled engines, the approximately 209-foot-tall (63.6-meter) rocket took off at 12:15 am EDT (04:15 UTC), or 12:15 pm local time at the seaside spaceport at Wenchang.
About 10 minutes later, the Long March 10B booster descended from space and guided itself into a four-legged frame affixed to an offshore vessel. Tensioned cables stretched over the ship in a grid pattern captured the rocket as it shut down its landing engines, leaving the smoldering booster hanging in midair. The rocket's upper stage continued into orbit and deployed a payload known only as CX-26. Chinese officials hailed the flight as a "complete success."
"A historic day in China's space program!" wrote Mao Ning, a spokesperson for the Chinese Foreign Ministry, on X. "China's Long March 10B has successfully completed its maiden flight-and recovered its first stage via a sea-based net. This marks the country's first-ever controlled rocket recovery. A major leap toward reusable launch capabilities."
The landing on Friday makes the China Aerospace Science and Technology Corporation (CASC) and its subsidiary, the China Academy of Launch Vehicle Technology (CALT), the third enterprise to accomplish this feat. SpaceX did it with its Falcon 9 rocket in 2015 and with its Starship/Super Heavy booster in 2024. Blue Origin landed its New Glenn booster on an offshore platform for the first time last November.
SpaceX and Blue Origin use propulsive landings to return their Falcon 9 and New Glenn boosters to offshore platforms or onshore landing pads. With Starship, SpaceX pioneered a new method of catching the rocket's reusable booster back at its launch pad using mechanical arms mounted to the launch tower.
The Long March 10B employs a different approach for recovery, combining an offshore vessel floating downrange with the catch technique somewhat like what SpaceX uses for Starship. Catching the rocket in this way reduces the effect of reuse on payload capacity. The Long March 10B doesn't have to carry the extra mass of landing legs, and recovering it downrange reduces how much fuel the rocket must consume during its descent.
