China's Tianwen 1 Mars probe completed a deep-space maneuver about 29.4 million kilometers away from Earth on Oct 9 under various constraint conditions and with concern for propellant conservation.
The probe has made two midcourse maneuvers and is expected to travel another four months before reaching Mars, during which another two or three orbital corrections will be carried out.
The Mars probe's mission includes six stages: the launch, the Earth-Mars transfer, entering Mars' gravitational field, orbiting Mars, landing and scientific experiments.
The probe is now enroute to Mars with its flight controlled and powered by the orbiter.
The entire transfer period will last about six and a half months.
