China's Jiu-3 Reusable Rocket: How It Differs From SpaceX's Falcon-9 LandSpace, a private Chinese aerospace company, has achieved a significant breakthrough in rocket technology with the successful landing of its Jiu-3 rocket. During a test on August 19, 2026, the rocket's first stage successfully returned to Earth after delivering the Honggu-03 satellite to orbit. The second stage had already placed the satellite into its designated orbit, while the first stage executed a controlled descent and landed safely in Gansu Province without major issues. The Jiu-3 rocket uses liquid methane and liquid oxygen as propellants, differing from SpaceX's Falcon-9, which relies on kerosene-based RP-1 fuel and liquid oxygen. Both rockets utilize liquid oxygen to oxidize the fuel, but the choice of methane in the Jiu-3 is seen as a forward-looking approach. While Falcon-9's fuel system has been extensively tested and refined over years, the methane-based engine represents a new direction in rocket propulsion. The landing techniques of the two rockets also show distinct differences. The Jiu-3's first stage slows its descent by reigniting its engines after separating from the second stage, deploying landing legs to ensure a controlled touchdown. Similarly, Falcon-9 adjusts its speed and direction post-separation before landing on its legs. However, Falcon-9's landing technology has been refined through hundreds of missions, offering a proven track record of reliability. LandSpace's achievement marks its first successful recovery of a orbital-class booster, while SpaceX has been reusing Falcon-9 boosters for years. In July 2026, a Falcon-9 booster completed its 36th flight, highlighting the maturity of SpaceX's reusable rocket system.#falcon_9 #spacex #landspace #jiu_3 #honggu_03
China's Zhuke-3 rocket achieved a significant milestone in space transportation by successfully completing its first mission, marking a pivotal step in the nation's efforts to develop reusable rocket technology. The launch, conducted on August 19, 2025, saw the rocket deliver a payload to orbit while recovering its first stage via a vertical landing on land. This accomplishment underscores China's growing capabilities in space exploration and its competitive edge in the global aerospace industry. The Zhuke-3, developed by the private space company LandSpace, is a two-stage rocket with a diameter of 4.5 meters, a total length of 66.1 meters, and a payload capacity of approximately 570 tons. Its first stage features nine Tianyan-12A liquid-fueled engines using oxygen-methane propellant, along with a recovery system that includes a lattice control system, guidance system, and landing legs. These components enable the rocket to autonomously return to Earth after completing its orbital mission, a critical advancement in reducing the cost and complexity of space launches. The success of the Zhuke-3 mission builds on LandSpace's earlier achievements, including the recovery of the Long March-10B rocket's first stage from the ocean in July 2025 using a net-based retrieval system. This dual approach—land and sea recovery—demonstrates China's ability to adapt its technology to different operational environments. The Zhuke-3's successful landing on land, however, represents a more complex and ambitious feat, as it requires precise control and stability during descent. The significance of this achievement extends beyond technical innovation. It positions China as a major player in the global space race, particularly in the realm of reusable rocket technology.#china #landspace #zhuke_3 #tianyan_12a #long_march_10b
