据中国载人航天工程办公室消息,北京时间1月6日凌晨,空间站机械臂转位货运飞船试验取得圆满成功。
it was the first time that the robotic arm operated a large in-orbit spacecraft for a transfer test.这是我国首次利用空间站机械臂操作大型在轨飞行器进行转位试验。
1月6日凌晨,机械臂成功捕获天舟二号货运飞船(the arm secured the robotic 1 craft)。6时12分转位试验开始,天舟二号货运飞船与天和核心舱解锁分离(be unlocked and separated from the space station core 2 tianhe)后,在机械臂拖动下以核心舱节点舱球心为圆心进行平面转位(be moved into a predetermined position);而后,反向操作(reversed the maneuvers),直至货运飞船与核心舱重新对接并完成锁紧(re-docked with the core module and completed locking)。
此次试验,初步检验了利用机械臂操作空间站舱段转位的可行性和有效性(the test preliminarily verified the feasibility of using the mechanical arm to conduct a space station module transfer),验证了空间站舱段转位技术和机械臂大负载操控技术,为后续空间站在轨组装建造积累了经验(laid a foundation for the subsequent in-orbit assembly and construction of the country's space station)。
