China's Tianwen 1 Mars probe carried out its second midcourse correction maneuver on Sunday night, according to the China National Space Administration.

據國家航天局消息，9月20日晚，我國的“天問一號”火星探測器完成第二次軌道中途修正。

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.

國家航天局9月21日上午發佈聲明稱，9月20日晚11時許，在收到地面控制團隊的控制信號後，“天問一號”探測器四臺120N發動機同時點火，工作20秒，完成了軌道修正任務。

By Monday morning, Tianwen 1 had traveled 160 million kilometers in an Earth-Mars transfer trajectory toward the red planet and was nearly 19 million km from Earth, it added.

截至9月21日上午，“天問一號”探測器已經在地火轉移軌道上飛行了1.6億公里，距離地球約1900萬公里，仍在繼續飛向火星。

China launched Tianwen 1, the country's first independent Mars mission, on July 23 at the Wenchang Space Launch Center in Hainan province, opening the nation's planetary exploration program.
