China News Agency, Beijing, October 9th (Guo Chaokai) At 23:00 Beijing time on October 9, under the control of the flight control team of China’s first Mars exploration mission, the main engine of the Tianwen-1 probe ignited for more than 480 seconds, successfully completing the deep Air maneuver.

Experts said that in order to reduce the flight deviation, the orbit control performed by the probe to fly along a predetermined orbit is called correction.
The orbital control performed by changing the current orbit of the probe into a new orbit is called maneuvering.
The orbital maneuver was carried out in deep space approximately 29.4 million kilometers from the earth.
The orbit design of the Tianwen-1 probe comprehensively considered various constraints from launch to Mars capture and made the propellant consumption as small as possible, and adopted the strategy of conducting a deep space maneuver during the transfer process.

The China Tianwen-1 probe was successfully launched on July 23 and was directly sent to the ground fire transfer orbit by the Long March 5 carrier rocket. During the flight, the ground-moon photo acquisition, two midway corrections of the orbit, and payload self-checking were successfully completed. .
In the future, the Tianwen-1 probe will rendezvous with Mars in the current orbit about four months later, during which time it will implement two or three midway corrections to its orbit.
