China recovered its first reusable rocket and showed a new way to do it

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. In a statement, CASC said the Long March 10B test flight “validated key core technologies” for a reusable launch architecture, such as multiple engine restarts with high-altitude ignition, high-precision navigation and control, and the first capture and recovery using a net system on a sea-based platform. A heavier configuration, known simply as the Long March 10, is a key part of China’s Moon program. This more powerful rocket will combine three Long March 10 first stage boosters—each reusable—together to generate more thrust at liftoff. A second stage and third stage will propel Chinese astronauts and their lunar landers toward the Moon. The Chinese government says it aims to land its citizens on the Moon by 2030. Friday’s launch was a small step toward that goal. China launched a scaled-down version of the Long March 10A rocket in February with a prototype of the Mengzhou capsule to test the spacecraft’s launch abort system, which would trigger to whisk crew members away from a failing rocket. The Mengzhou test went well, and remarkably, the Long March 10A continued flying after the capsule fired away from the booster, eventually coming back to Earth for a controlled splashdown at sea. The Long March 10B took this achievement a step further with a midair catch. Multiple commercial and government-backed Chinese rocket companies are trying to level the playing field with the United States. China is the world’s second-largest spacefaring nation, but US companies, dominated by SpaceX, are launching payloads into orbit about twice as often as Chinese rockets. SpaceX’s blistering launch cadence is made possible by the partially reusable Falcon 9, something Blue Origin and Chinese companies are seeking to emulate. US military officials have identified China’s advancements in reusable rocketry as a key to unlocking the country’s ability to potentially threaten US assets in space. “I’m concerned about when the Chinese figure out how to do reusable lift that allows them to put more capability on orbit at a quicker cadence than currently exists,” said Maj. Gen. Brian Sidari, the Space Force’s deputy chief of space operations for intelligence, at a conference last year. The next flight of the Zhuque-3 rocket could happen later this month or in August, with LandSpace again expected to attempt to land the booster downrange. Other Chinese rockets that could soon achieve reusability include Space Pioneer’s Tianlong-3, China Commercial Rocket Co.’s Long March 12B, CAS Space’s Kinetica-2, i-Space’s Hyperbola-3, and Galactic Energy’s Pallas-1. Further into the future, China aims to debut a huge new reusable rocket on the scale of Starship named the Long March 9. In the United States, there are SpaceX’s Falcon 9, Falcon Heavy, and Starship, along with Blue Origin’s New Glenn rocket. Rocket Lab is aiming to launch its first medium-lift Neutron rocket with a reusable booster by the end of the year. Relativity Space is developing a partially reusable heavy-lifter named Terran R, and Firefly Aerospace is partnering with Northrop Grumman on the Eclipse rocket, which officials say will eventually have a recoverable and reusable first stage. Stoke Space has the bolder ambition of a fully reusable rocket called Nova. Several European companies also plan to test reusable rocket technology, but their vehicles are not as mature as many of the US and Chinese rockets. Rocket builders in India, Japan, and Russia have reuse in their roadmaps, with varying degrees of realism. The proliferation of Chinese rocket companies, scattered across four land-based spaceports and multiple ocean-going launch platforms, should set up China to quickly ramp up its launch cadence. “It probably won’t be but a few years before they’re able to achieve a much higher launch cadence,” Galbreath said. “They also have more launch sites than the United States currently, so if you couple their number of sites with reusability, they could surpass us in terms of launch rate, which in and of itself is more of a pride thing. But it’s the capability that’s being launched as a result of that that could actually have a significant impact on our competition, and if we got to it, a conflict. “There’s nothing wrong with competition as long as it’s peaceful,” Galbreath said. “That can drive innovation, but I’m concerned that the historic example of Chinese behavior has not always remained peaceful. So, we have to look at everything they do carefully. On the one hand, they’re competing with SpaceX, but we know that because of the way China has organized its military, its space capabilities, all under military control, that there is significant utility that their armed forces will receive from this race.”
