因维机甲雨点般的落下，光怪陆离的蟹形装甲战机乘着强有力的推进器，向哨兵们俯冲袭来。

The robotic spacecraft ran its four 120-Newton thrusters for 20 seconds at around 11 pm after receiving control signals from its ground controllers, the administration said in a statement on Monday morning.

国家航天局9月21日上午发布声明称，9月20日晚11时许，在收到地面控制团队的控制信号后，“天问一号”探测器四台120N发动机同时点火，工作20秒，完成了轨道修正任务。

小型推进器在让“新视野号”旋转的同时，也导致其稍稍偏离航向。
