我国首次实现火箭陆地回收！

2026年8月19日，朱雀三号遥二运载火箭在东风商业航天创新试验区发射升空，火箭一子级按预定程序成功完成陆地回收，飞行任务取得圆满成功。

此次任务是我国首次成功实施重复使用运载火箭一子级着陆腿方式回收，标志着我国重复使用火箭技术取得重大突破。

In a landmark moment for China's space sector, a huge rocket booster gently touched down on China's northwestern desert terrain on Wednesday morning, marking the country's first-ever successful land recovery of a rocket.

Footage from surveillance drones flying near the landing trajectory shows that during the final phase of its return to Earth, at an altitude of roughly three kilometers above the ground, the booster ignited an engine at the center of its base for propulsive deceleration.

Shortly before touchdown, its four landing legs deployed. At the instant of touchdown, the engine shut down, and the legs held the over 40-meter-tall first stage firmly upright on the concrete landing pad in Minqin county, Gansu province.

The recovery has made LandSpace the second in China to bring a booster back to Earth intact and the first to successfully land a rocket on Chinese soil.

重复使用火箭助力低轨星座组网

朱雀三号运载火箭是由国家航天局批复立项的新一代低成本、大运力、高频次、重复使用液氧甲烷运载火箭型号。此型火箭采用单芯级两级串联构型，全箭长66.1米，一二子级箭体直径4.5米，整流罩直径5.2米。

型号研制负责人介绍，箭体主结构采用不锈钢材料，以“燃箱在上、氧箱在下”的总体布局优化飞行质心。

火箭一子级配备九台天鹊-12A液氧甲烷发动机，动力系统可在40%至110%的推力范围间调节，可在完成轨道发射后实施垂直回收与再利用。

The 66.1-meter ZQ 3 Y2, a gigantic craft made primarily by stainless steel, blasted off at 7:35 am from its dedicated launch service tower at the Jiuquan Satellite Launch Center, which is about 390 kilometers away from the landing site, in northwestern China's Inner Mongolia autonomous region.

Technical specs from LandSpace shows the ZQ 3 Y2 had a diameter of 4.5 meters and weighed about 570 metric tons when fully fueled.

The rocket was propelled by nine TQ 12A methane engines on the first stage and a TQ 15A methane engine on the second stage, boasting a liftoff thrust of nearly 770 tons that was enough to transport heavy satellites to low-Earth or Sun-synchronous orbits.

2026年4月，我国部署加强新一代通信网等“六张网”规划建设。

站在“十五五”开局之年，以卫星互联网为代表的太空新质生产力、以重复使用火箭为代表的太空新质“运力”是实现空天地海一体、通感算智融合的重要“底座”。

业界专家认为，朱雀三号“液氧甲烷推进剂+不锈钢箭体+垂直回收”技术路线的成功验证，有望助力我国低轨星座加速组网。

火箭重复使用次数越多发射成本越低

“一般情况下，液氧甲烷燃料费用占发射成本的1%至3%，火箭一子级成本占全箭成本的约70%。火箭重复使用次数越多，发射成本越低。”型号研制负责人说。

据介绍，蓝箭航天计划尽快实施回收箭体的复用任务，加快构建“发射-回收-检测-复用”闭环体系，为后续高频次、低成本商业化运营奠定基础。

下一步，国家航天局将持续推进我国重复使用运载火箭工程化应用，切实提升我国大运力、低成本、高频次进入空间能力。
