长征十号乙火箭完成全球首次海上网系回收 更多现场画面 专家解读火箭发射回收过程

According to the China Aerospace Science and Technology Corporation, at 12:15 PM today, a Long March-10B carrier rocket launched from the Hainan Commercial Space Launch Site, successfully sending a satellite into its predetermined orbit. Simultaneously, the successful controlled recovery of the rocket's first stage marks a new historic breakthrough for my country in the field of reusable rocket technology. At 12:15 PM, the Long March-10B carrier rocket ignited and lifted off. Approximately six minutes after the first and second stages separated, the first stage returned vertically and was successfully recovered at a sea-based recovery platform using a net-based capture method. The Long March-10B carrier rocket became my country's first successfully recovered reusable carrier rocket, and also the world's first carrier rocket recovered using a net-based system. The Long March 10B is a large liquid-fueled launch vehicle with a 5-meter diameter, two-stage tandem configuration. The first stage is identical to that of the Long March 10A launch vehicle, using liquid oxygen and kerosene propellants. The total liftoff thrust is approximately 890 tons, and the liftoff weight is approximately 760 tons. The maiden flight rocket was approximately 63 meters long, with a reusable payload capacity of 16 tons to low Earth orbit, meeting the needs of various missions such as low-Earth orbit satellite internet constellation deployment and large commercial satellite launches. The Long March 10B launch vehicle development team will continue to optimize rocket performance and accelerate the iterative upgrade of reusable rocket technology, expecting to complete the reusable flight of the first stage rocket by the end of this year. The maiden flight of the Long March 10B launch vehicle was a complete success. The maiden flight of the Long March 10B launch vehicle was a complete success. At the launch test center of the Hainan Commercial Aircraft Launch Vehicle Co., Ltd., CCTV reporter Cui Xia witnessed this historic moment. What was the situation like on site? CCTV reporter Cui Xia: From rocket ignition to successful recovery, it was only 8 minutes. Being there felt like watching a blockbuster movie. Let's first interview Rong Yi, the chief designer of the Long March 10A carrier rocket. Rong Yi, China Aerospace Science and Technology Corporation: First of all, thank you all for your continued attention and concern. The core of this flight test was to verify our country's unique and pioneering marine-based recovery technology. The mission was successfully completed. From our initial conception to the blueprints more than four years ago, and then to turning it into reality, the hard work of the entire team has yielded today's results, and we are very happy and proud! The first stages of the Long March 10B and Long March 10A are from the same source. In the subsequent application of reusable technology, the two rocket teams will continue to integrate. Reusability presents many challenges, but now that we have taken the first step, we will not stop. In the future, we will mature the reusable technology, improve its reliability, and reduce costs. Lou Luliang, China Aerospace Science and Technology Corporation: This mission deserves a perfect score of 100 for the Long March 10B! Both of the established main objectives were successfully achieved! Chinese aerospace engineers have their own pursuit of technological innovation and an understanding of rockets. Adopting a recovery method more suitable for ourselves is also a contribution to the world's aerospace industry. The successful recovery and reuse of the first stage can significantly reduce costs and improve efficiency. In deep space exploration, China can go even further. After the first stage is recovered, it will be inspected and restored as soon as possible. If conditions permit, we hope it can be put back into flight within six months. Obtaining more practical data through flight will accelerate our understanding of the "recovery-reuse" process. Long March 10B Completes World's First Sea-Based Net System Recovery At 12:15 PM today, the Long March 10B rocket launched from the Hainan Commercial Space Launch Site. After completing its payload mission, its first stage separated from the second stage and, after performing maneuvers such as gliding, aerodynamic deceleration, powered deceleration, and hovering in the air, landed steadily on the sea-based recovery platform. The entire process, from launch to capture, lasted approximately eight minutes.
