Mars probe marks first step '天问一号'首次轨道修正

China's Mars probe Tianwen-1 successfully carried out its first orbital correction Sunday morning, according to the China National Space Administration (CNSA).

据国家航天局消息，北京时间8月2日，中国火星探测器"天问一号"成功实施了首次轨道修正。

The probe conducted the orbital correction at 7 am (Beijing Time) after its 3,000 N engine worked for 20 seconds, and continued to head for Mars.

当日早7时，"天问一号"3000牛发动机工作20秒完成了轨道修正，并继续飞向火星。

Before the orbital correction, the Mars probe had traveled more than 230 hours in space, and was about 3 million km away from the Earth. All the systems of the probe were in good condition.

此次轨道修正前，"天问一号"已在太空中飞行逾230个小时，距地球约300万公里，所有系统均状态良好。

The probe will undergo several orbital corrections in a more than six-month journey to Mars, said the CNSA source.

国家航天局表示，在6个多月前往火星的旅途中，"天问一号"将进行多次轨道修正。

The Mars probe is expected to reach the red planet around February 2021.

预计"天问一号"火星探测器将在2021年2月前后到达火星。

After entering the orbit, it will spend another two to three months surveying the candidate landing sites before landing.

进入轨道后，"天问一号"还会在着陆前花两三个月对候选着陆点进行考察。
