China recovers rocket booster at sea using net system

China on Friday successfully launched its Long March 10B carrier rocket on its debut flight, recovering the first stage using a net attached to a sea platform — a method the China Aerospace Science and Technology Corporation (CASC) called the "world's first net-based recovery of a launch vehicle."nytimes+1

A New Chapter in Rocket Reusability

The Long March 10B lifted off at 12:15 a.m. Eastern (0415 UTC) on July 10 from the Hainan Commercial Space Launch Site, also known as the Wenchang Commercial Space Launch Site, on China's southern island province. The rocket sent a satellite to orbit before the first stage separated and descended to a controlled landing on a sea-based platform roughly 430 kilometers downrange from the launch site.facebook+2

The recovery method differs from SpaceX's propulsive vertical landings. Instead of guiding the booster to a pinpoint touchdown, the Long March 10B's first stage was caught by a net system mounted on a ship at sea. According to U.S. News & World Report, citing Reuters, the net-based approach "helps simplify the rocket's onboard structure," reducing complexity and weight compared to propulsive landing systems.japantimes+1

The achievement makes China the second country after the United States to successfully recover an orbital-class rocket booster, according to SpaceNews. China had made an earlier attempt at reusable rocket recovery in February with a Long March 10A, which completed a controlled descent but did not achieve a full operational recovery.spacenews+1

Strategic Implications

The Long March 10B is designed to carry at least 16 tonnes to a 200-kilometer low Earth orbit in reusable mode. Experts quoted by Chinese state media described the milestone as ushering China into a "rocket recovery era," with the capability expected to dramatically reduce launch costs for the country's growing constellation of commercial satellites.wikipedia+1

The New York Times reported that the launch and recovery "could represent a long-awaited breakthrough for Chinese satellite companies," which have been constrained by limited and expensive launch capacity.nytimes

Market Reaction

Hong Kong-listed stocks rallied on Friday, with the benchmark Hang Seng Index climbing 1.86 percent in the morning session. While broader market gains were driven in part by the blockbuster U.S. listing of SK Hynix, Chinese commercial space-related shares benefited from the Long March 10B milestone, with investors betting that reusability will unlock a new wave of demand for Chinese launch services.english.news
