From countdown to capture: Witnessing a rocket's milestone

As a space journalist who has covered dozens of launches across the country, I long thought I had grown accustomed to the roar of liftoff and the routine of countdowns. Yet standing on a rooftop at the Hainan International Commercial Aerospace Launch Center on Friday morning, waiting for the Long March 10B rocket to lift off, I felt the same mix of nervousness, excitement and quiet anticipation that I experienced on my very first launch assignment.

When the first stage was successfully captured by the cable-net recovery system about six minutes after stage separation, cheers erupted among reporters. On the ride back to our hotel, I found myself replaying the recovery footage on my phone, exchanging clips and screenshots with fellow journalists. That split second when the booster locked safely into the net is the kind of frame that stays etched in a reporter's memory for years.

Having covered earlier recovery attempts involving the Long March 12A and ZQ 3 rockets, I know firsthand just how formidable the challenge of rocket reusability is. Guiding a heavy booster back through the atmosphere with pinpoint precision, managing engine reignitions and aerodynamic control, and executing a controlled recovery require flawless coordination across propulsion, navigation, materials science and real-time command systems.

Every setback in previous tests underscored how many variables must align for success. That is why today's breakthrough feels especially gratifying. I share the immense pride of the researchers and engineers at the China Academy of Launch Vehicle Technology who turned this vision into reality.

What makes this milestone even more remarkable is China's independent path of innovation. Unlike conventional recoveries on ground landing pads or offshore drone ships used in the United States and in previous domestic programs, the Long March 10B debuted the world's first operational sea-based net-capture recovery system. By transferring landing hardware from the rocket to the recovery vessel, engineers reduced dead weight and created a distinct, cost-effective technical approach. It is a vivid reflection of the creativity of China's space researchers and the country's growing scientific and technological capabilities.

Beyond the technical achievement, the Long March 10B carries far-reaching strategic significance. Built for large-scale low-Earth-orbit constellation deployment and high-volume commercial launches, it will directly enhance China's competitiveness and influence in the global space sector.

Just as importantly, it is not a standalone model but an integral part of the Long March 10 manned lunar rocket family. Each commercial mission will validate engine reusability, recovery system reliability and rapid launch turnaround capability, forging a development model in which commercial operations drive technological progress for major national programs. This iterative approach will steadily build the expertise needed for China's future manned lunar landings and deep-space exploration.

To be sure, we must remain clear-eyed. A considerable gap still separates China from the US in mature, operational reusable rocket technology, and sustained, steady progress remains essential. But after witnessing today's historic success firsthand, I am confident that China's space community will continue narrowing that gap and further establish itself among the world's leading space powers.
