深空机动
deep-space maneuver
China's Mars probe Tianwen-1 successfully completed a deep-space maneuver after its main engine worked for over 480 seconds.
The maneuver took place 29.4 million km from Earth, aiming to help the probe achieve a sound rendezvous with Mars.
Going forward, the probe will travel along the Earth-Mars transfer orbit for about four months and complete two or three mid-course orbital corrections.
中国“天问一号”火星探测器主发动机点火工作480余秒，顺利完成深空机动。
此次轨道机动在距离地球大约2940万千米的深空实施，旨在帮助探测器实现与火星的完美交会。
“天问一号”将在当前轨道飞行约4个月后与火星交会，其间还将实施两到三次轨道中途修正。
