Success! China Launches & Recovers its' Long March 10B Rocket

from Google AI:

The Long March 10B (CZ-10B) is a medium-lift, partially reusable two-stage rocket operated by Chinarocket Co., Ltd., a commercial subsidiary of the China Academy of Launch Vehicle Technology (CALT). On July 10, 2026, the rocket made global history during its maiden flight. It successfully delivered its satellite payload into orbit and accomplished China's first-ever successful recovery of an orbital-class rocket booster.

The Historic Net-Based Recovery System

Unlike the vertical ground and autonomous drone ship landings pioneered by companies like SpaceX, the Long March 10B utilizes a world-first marine net-capture system.

• The Mechanism: Instead of deploying heavy landing legs, the first-stage booster is built with structural "landing hooks" near its top.
• The Ship: After separating from the second stage, the booster performed a controlled, propulsive descent downrange onto a specialized floating platform named the LingHangZhe (Navigator).
• The Catch: Tensioned, moving cables on the ship's structural frame automatically adjusted to snare the rocket's hooks, absorbing its remaining energy for a soft landing.
• The Advantage: Catching the booster via wires avoids the severe stress of a hard structural landing and eliminates the heavy weight and aerodynamic drag of traditional landing legs.

Rocket Specifications & Design

According to official details tracked on platforms like Next Spaceflight, the Long March 10B is structured as a mixed-propellant vehicle:

• Dimensions: Measures 63 meters in height and 5 meters in diameter.
• First Stage: Inherited directly from the crewed Long March 10A. It is powered by seven YF-100K staged-combustion engines burning kerosene and liquid oxygen (kerolox), outputting roughly 8,700 kilonewtons of thrust.
• Second Stage: Powered by a single YF-219 engine utilizing liquid methane and liquid oxygen (methalox). This marked the first flight test of this specific engine.
• Payload Capacity: Capable of lofting at least 16 metric tons to Low Earth Orbit (LEO) in its reusable configuration.

Strategic Purpose & Future Plans

The development of the Long March 10B serves two primary strategic goals for China's expanding space program:

• Commercial Competitiveness: Designed to provide highly cost-effective, routine launch services for commercial satellite constellations.
• Lunar Program Precursor: It acts as the "younger sibling" to the crewed Long March 10A. Flight data gathered by the 10B directly validates the recovery, guidance, and engine technologies needed for the heavier, three-core Long March 10. The main Long March 10 is central to China's objective of landing astronauts on the Moon by 2030.

State media reported that the China Aerospace Science and Technology Corporation (CASC) is already inspecting the recovered first stage with plans to re-fly the exact same booster before the end of 2026.
